Finally, we will examine various strategies for managing and treating stress.
Introduction to Stress and Its Biology
Introduction to Stress and Its Biology

Stress has become a major issue for today’s society. It is present in everyone’s life, and not recognizing it can lead to significant health problems. Understanding what causes it and how it affects us is the first step towards learning how to manage it effectively. The biology of stress can be complex, but looking at its different components will help us understand it better.
n
Stress is essentially an emotional and physical response to a stimulus that our body perceives as threatening. This response is caused by a complex network of hormones, neurotransmitters, and physiological responses. The hypothalamic-pituitary-adrenal (HPA) axis is one of the main components of this network. It is responsible for the production of cortisol, a hormone that helps regulate the body’s response to stress.
n
The endocrine system helps regulate the hormones released during stressful situations, while the autonomic nervous system (ANS) is responsible for controlling the body’s involuntary responses, such as increased heart rate and respiration. Neurotransmitters are also involved in the response to stress. These are chemicals that are released by nerve cells and influence the way we think and behave.
n
The role of glucocorticoids, such as cortisol, is to help regulate the body’s response to stress. They are released by the adrenal glands and can have a number of effects on the body, such as increasing energy levels and helping to control inflammation. Epinephrine (adrenaline) is another hormone that is released during stressful situations. It is responsible for the “fight or flight” response, increasing heart rate and respiration.
n
Cortisol is also released in response to stress and is responsible for regulating metabolism and energy levels. Norepinephrine is a neurotransmitter that helps regulate the body’s response to stress by controlling heart rate and blood pressure. Serotonin is another neurotransmitter that helps modulate mood, anxiety, and appetite.
The Role of the Hypothalamic-Pituitary-Adrenal Axis in Stress
The hypothalamus is a section of the brain that plays a central role in the regulation of stress responses. It is connected to the pituitary gland, which is connected to the adrenal gland. This connection is known as the hypothalamic-pituitary-adrenal (HPA) axis. This axis is responsible for leading the body’s response to stress.
When an individual experiences stress, the hypothalamus triggers a cascade of events in the body. It tells the pituitary gland to secrete hormones, and the pituitary gland tells the adrenal gland to secrete adrenaline and cortisol. Adrenaline is a hormone that increases heart rate, respiration, and blood pressure, while cortisol is a hormone that increases glucose levels in the blood.
The effects of cortisol on the body are complex. It can reduce inflammation and immune responses, but over time it can also lead to an increased risk of certain diseases such as cardiovascular disease and metabolic syndrome. Cortisol also acts on the brain, namely the hippocampus, which is involved in memory and other cognitive functions. Chronic stress can cause changes in the hippocampus that can result in impaired cognitive functioning.
The HPA axis works in coordination with other systems such as the sympathetic nervous system and the parasympathetic nervous system. The two systems are responsible for maintaining balance in the body. The sympathetic nervous system is responsible for helping the body respond to stress and danger, while the parasympathetic nervous system is responsible for calming the body down and restoring balance.
The HPA axis works to maintain balance between these two systems. In response to stress, the HPA axis triggers a cascade of events that prepare the body for fight or flight. This includes increasing heart rate, blood pressure, respiration, and glucose levels as well as decreasing inflammation and immune responses. Over time, this repeated activation of the HPA axis can lead to an array of physiological and psychological problems.
The role of the HPA axis in stress is crucial for maintaining homeostasis in the body. It helps the body respond to stress and danger in an efficient way. However, when it is overactivated due to chronic stress or trauma, it can have a significant impact on physical and mental health.
The Endocrine System and Stress
The hypothalamus, a part of the brain, is responsible for communicating messages to the endocrine system. It does this by releasing hormones that stimulate the pituitary gland, one of the most important glands in the body. The pituitary gland then releases hormones that influence other endocrine glands, such as the adrenal glands, thyroid, and gonads. These hormones are key in the body’s response to stress.
The Role of Glucocorticoids
Glucocorticoids are hormones released by the adrenal glands in response to stress. These hormones have several functions, including helping to reduce inflammation and regulating blood sugar levels. Glucocorticoids also help the body to conserve energy in times of stress by activating the breakdown of proteins and fats into glucose, which can be used by the body for energy. Glucocorticoids also help to regulate the immune response and can reduce fear and anxiety.
The Role of Epinephrine (Adrenaline)
Epinephrine is another hormone released in response to stress. It helps to increase heart rate and blood pressure, which allows more oxygen and nutrients to be available to tissues and organs. Epinephrine also increases alertness and sharpens focus, allowing an individual to respond more quickly and effectively to a stressful situation.
The Role of Cortisol
Cortisol is considered the primary glucocorticoid hormone. It is released in response to stress and helps to regulate energy availability and metabolism. In addition, cortisol helps to regulate inflammation, salt retention, and immune responses. Cortisol levels are highest during the early morning hours and decrease throughout the day.
The Role of Norepinephrine
Norepinephrine is a neurotransmitter released in response to stress. This hormone helps to increase heart rate and respiration, along with blood pressure. Norepinephrine also affects moods and mental alertness, helping an individual cope with stress. It is also important for long-term memory formation.
The Role of Serotonin
Serotonin is a neurotransmitter that helps regulate moods, sleep, appetite, and digestion. It is also responsible for helping an individual cope with stress and anxiety. Low serotonin levels can lead to depression or other emotional issues.
The Autonomic Nervous System and Stress
The Autonomic Nervous System and Stress
The Autonomic Nervous System (ANS) is responsible for controlling our internal organs, and its primary function is to maintain homeostasis. During times of acute stress, the ANS is responsible for releasing a number of hormones and neurotransmitters that help the body to respond to the stressful situation. The ANS is divided into two branches, the sympathetic nervous system and parasympathetic nervous system, and each of these systems plays an important role in the body’s response to stress.
The sympathetic nervous system is often referred to as the “fight or flight” response. It is activated when the body senses a threat or a stressful situation. Upon activation, this system releases a number of hormones and neurotransmitters, such as epinephrine, norepinephrine, and cortisol. These hormones and neurotransmitters increase heart rate, blood pressure, and breathing rate, and they also cause blood vessels to constrict. These physiological changes are what provide the body with the energy needed to either fight or flee from the perceived danger.
The parasympathetic nervous system is often referred to as the “rest and digest” response. It is activated when the body is in a relaxed state and it helps to slow down the heart rate and breathing rate, and it also helps to stimulate digestion. This system primarily operates in opposition to the sympathetic nervous system, as it helps to counterbalance the effects of the fight or flight response.
Understanding how the autonomic nervous system works during times of stress can be beneficial as it can help us to better manage the physical and emotional effects of stress. By understanding how our body responds to stress, we can better identify when we are in danger and when we need to take steps to relax and reduce our levels of stress.
Neurotransmitters and Stress
Neurotransmitters and Stress
Neurotransmitters are chemical messengers that play a key role in regulating brain function and behavior. When we experience stress, the body releases various hormones and neurotransmitters. These hormones and neurotransmitters can have a significant effect on our physical and mental well-being.
Serotonin: Serotonin is an important neurotransmitter involved in regulating mood, sleep, appetite, and sexual desire. It acts as a natural anti-depressant and can help reduce anxiety and stress levels. Low levels of serotonin can lead to depression, anxiety, and increased stress.
Norepinephrine: Norepinephrine is an important neurotransmitter involved in the body’s “flight-or-fight” response to stress. It helps to regulate our moods and energy levels and can increase alertness and focus. High levels of norepinephrine can lead to anxiety, insomnia, poor concentration, and impaired judgment.
Epinephrine (Adrenaline): Epinephrine (also known as adrenaline) is released during times of stress. It increases heart rate, breathing rate, and blood pressure. It also helps to increase alertness and focus. However, high levels of epinephrine can lead to feelings of anxiousness, restlessness, irritability, and difficulty sleeping.
Dopamine: Dopamine is a neurotransmitter that plays a role in pleasure, reward, motivation, and movement. Low levels of dopamine can lead to depression, low energy levels, and lack of motivation. High levels can lead to anxiety, irritability, agitation, restlessness, and difficulty sleeping.
Neurotransmitters play a major role in how we respond to stress. Understanding how these neurotransmitters work can help us better manage our stress levels and improve our overall mental and physical health.
The Role of Glucocorticoids
The Role of Glucocorticoids
Glucocorticoids, commonly known as corticosteroids, are a class of hormones that includes cortisol, corticosterone, and cortisone. These hormones are produced by the adrenal glands in response to stress. Glucocorticoids are potent stimulators of the body’s stress response, and they can also help regulate other physiological processes such as metabolism, immune system response, and inflammation.
Glucocorticoids are released in response to physical or psychological stress, and their primary function is to prepare the body for fight or flight – the body’s natural response to danger. Glucocorticoids increase heart rate, blood pressure, and breathing rate, and they can also mobilize energy stores in the form of fatty acids and glucose. Cortisol, in particular, is important in regulating glucose metabolism and has been linked to appetite regulation, energy storage, and immune system response.
Glucocorticoids also have an inflammatory effect on the body. They can reduce inflammation by inhibiting the production of certain inflammatory molecules, such as cytokines. This can help reduce pain and swelling associated with inflammation. However, long-term exposure to glucocorticoids can have negative effects on the body, such as an increased risk of infection, increased blood pressure, and increased risk of osteoporosis.
In summary, glucocorticoids play an important role in the body’s stress response. They help regulate metabolism, immune system response, and inflammation, and can help mobilize energy stores in times of stress. However, long-term exposure to glucocorticoids can have negative effects on the body, so it’s important to reduce stress levels where possible and to manage stress effectively.
The Role of Epinephrine (Adrenaline)
The Role of Epinephrine (Adrenaline) on Stress
Epinephrine, also known as adrenaline, is a hormone and neurotransmitter produced by the adrenal glands which plays a key role in the body’s stress response. It is released in response to physical or psychological stress and prepares the body for fight-or-flight. Epinephrine increases heart rate, blood pressure, respiration, and glucose levels. It also constricts the pupils, stimulates the release of fatty acids from fat cells and increases blood flow to skeletal muscles.
Epinephrine has both short-term and long-term effects on the body. In the short-term, it can cause a feeling of alertness and energy. The increased heart rate and respiration can cause a racing heart and difficulty breathing, while the constricted pupils can cause blurred vision. In the long-term, these effects can lead to fatigue, anxiety, insomnia, headaches, and other symptoms of chronic stress.
Epinephrine has been found to play a role in the development of anxiety disorders such as phobias and panic disorder. Research has shown that when people with these disorders are exposed to a stressful situation, they produce more epinephrine than those without anxiety disorders. This suggests that epinephrine may play a role in the development of these disorders or at least contribute to their severity.
Epinephrine is also thought to be involved in the development of post-traumatic stress disorder (PTSD). People with PTSD produce higher levels of epinephrine than those without PTSD when exposed to traumatic situations.
Due to its role in the stress response, epinephrine has become a target for treatment of stress-related disorders. Several medications have been developed that target epinephrine levels in the body, including beta-blockers and monoamine oxidase inhibitors (MAOIs). These medications can help reduce the physical symptoms of stress and can also improve mood and reduce anxiety.
Overall, epinephrine plays an important role in the body’s stress response and has been linked to several mental health disorders. Its effects can lead to both short-term and long-term changes in the body, and its involvement in anxiety and PTSD make it an important target for treatment.
The Role of Cortisol
The Role of Cortisol
Cortisol is a hormone produced by the adrenal glands. It is the primary hormone involved in the body’s stress response, and its levels increase when the body is under stress. Cortisol affects many different systems in the body, and understanding this hormone is important for understanding how the body responds to stress.
Functions of Cortisol
Cortisol has many important functions in the body, including regulating metabolism, regulating the body’s response to stress, and maintaining healthy blood sugar levels. Additionally, cortisol plays an important role in inflammatory processes and immune response.
The Stress Response and Cortisol
When the body experiences a stressful situation, cortisol is released. This puts the body in “fight or flight” mode, increasing heart rate and blood pressure and preparing the body to respond to the situation. Cortisol also suppresses non-essential bodily functions, such as digestion and reproduction, so that energy can be diverted to the areas needed for fight or flight.
Long-Term Effects of Cortisol
Prolonged exposure to stress can lead to an imbalance of cortisol in the body. This can cause a host of health problems, such as depression, anxiety, fatigue, difficulty sleeping, weight gain, digestive issues, and weakened immune system. It is important to recognize the signs of prolonged exposure to stress and manage it to avoid these long-term effects.
The Role of Norepinephrine
The role of norepinephrine in stress is complex. It is a neurotransmitter and a hormone released both by neurons and the adrenal gland. It takes part in the sympathetic nervous system and is responsible for the fight or flight response in a stressful situation. Norepinephrine plays an important role in the regulation of heart rate, respiration, and blood pressure, and helps prepare the body for physical activity in response to a stressful situation. It is also involved in the regulation of anxiety and memory, as well as emotional responses.
Norepinephrine interacts with several hormones and neurotransmitters, including epinephrine, cortisol, and serotonin. It has been found to have an inhibitory effect on cortisol release during stress, possibly limiting its potential effects. In addition, it has been shown to have a stimulating effect on serotonin production, resulting in improved mood and reduced anxiety.
The release of norepinephrine during times of stress is also linked to improved cognitive performance. Studies have shown that it can improve memory, focus, and attention. It is also thought to help regulate negative emotions, such as fear and anxiety. This is because norepinephrine helps to control the body’s response to stressful events.
Norepinephrine is an important part of the body’s response to stress. While it can help to improve cognitive performance and regulate negative emotions, it is important to note that too much of it can be detrimental. Excessive levels of norepinephrine can lead to anxiety, irritability, insomnia, and even depression. Therefore, it is important to manage stress levels appropriately in order to maintain healthy levels of norepinephrine in the body.
The Role of Serotonin
The Role of Serotonin
Serotonin is a neurotransmitter that affects many aspects of the body, including mood, sleep, appetite, and digestion. Serotonin is involved in the stress response in two ways: it is released from nerve endings in the brain and it is released from platelets.
The release of serotonin from nerve endings in the brain is part of the autonomic nervous system’s reaction to stress. It is believed that this release of serotonin helps to regulate the body’s response to stress by acting as a calming agent.
The release of serotonin from platelets, however, is a different story. Platelets contain large amounts of serotonin, so when the body is under stress, this serotonin is released into the bloodstream. Studies have shown that increased levels of serotonin in the bloodstream have been linked to increased feelings of anxiety and depression.
The role of serotonin is complex and not fully understood. It is thought that serotonin plays an important role in mood regulation and can be used as a target for treatments for stress-related conditions. Researchers are continuing to explore the role of serotonin in the body’s response to stress.
Physiological Changes in Stress
Physiological Changes in Stress
Stress affects the body in a variety of ways. The physiological changes that occur in response to stress, such as increased heart rate, increased blood pressure, and increased respiration rate, are important for survival in the short term. In the long term, however, these physiological changes can be detrimental to health and well-being.
The body’s response to stress is mediated by the hypothalamic-pituitary-adrenal (HPA) axis. This system is responsible for releasing hormones such as cortisol, epinephrine (also known as adrenaline), and norepinephrine in response to stress. These hormones are known as “stress hormones” and they are responsible for the physiological changes that occur when someone is stressed.
The release of cortisol is one of the most important physiological changes that occur in response to stress. Cortisol is a hormone released by the adrenal glands in response to stress and it plays an important role in the body’s fight-or-flight response. Cortisol increases blood sugar levels, which provide energy for the body to respond to stress. It also helps to suppress the immune system, which can help reduce inflammation and pain.
The release of epinephrine and norepinephrine are also important when responding to stress. These hormones are released by the adrenal glands and affect the cardiovascular system. They can increase heart rate, blood pressure, and respiration rate.
When a person is exposed to chronic stress, their body may become over-stressed. This can lead to an imbalance of stress hormones, which can contribute to a range of physical and mental health issues. It is important to manage stress in order to maintain health and wellbeing.
Cardiovascular Effects of Stress
The HPA axis starts with a signal from the hypothalamus, an area in the brain responsible for releasing hormones. This signal stimulates the pituitary gland to secrete adrenocorticotropic hormone (ACTH). ACTH then signals the adrenal glands to release hormones, such as corticotropin-releasing hormone (CRH). This in turn triggers a cascade of physiological changes that result in a heightened state of alertness, increased heart rate and blood pressure, and increased levels of stress hormones. All of these changes lead to an increased workload for the cardiovascular system.n
These cardiovascular effects of stress can be beneficial in some situations. A rapid heart rate and increased blood pressure can boost energy levels and help people respond quickly and effectively to dangerous threats. However, in the long term, they can be detrimental to health. Prolonged stress can lead to the development of cardiovascular disease, atherosclerosis, and hypertension. Therefore, it is important to recognize and manage stress before it gets to this point.n
The best way to manage stress is to identify its sources and find effective coping strategies. Finding ways to relax and reduce anxiety can help reduce the impact of stress on the cardiovascular system. Exercise can also be incredibly helpful in managing stress. It helps reduce tension, increase energy levels, and improve mood. Finally, talking to a professional can provide support and guidance on managing stress effectively.
Gastrointestinal Effects of Stress
Gastrointestinal Effects of Stress
The gastrointestinal system is highly sensitive to both physical and psychological stress. In response to stress, the body produces hormones that can affect the functioning of the entire digestive system. These hormones may lead to a wide variety of gastrointestinal problems, including but not limited to:
- Increased gastric acid: Stress can lead to an increase in stomach acid production, leading to heartburn, indigestion, and even ulcers.
- A decrease in digestive enzymes: Stress can reduce the production of enzymes that are necessary for proper digestion.
- Changes in the microbiome: Prolonged periods of stress can alter the balance of bacteria in the gut, contributing to digestive issues.
Chronic stress can also lead to other gastrointestinal conditions such as irritable bowel syndrome (IBS), Crohn’s disease, and ulcerative colitis. Although a direct causal relationship has not been established, some studies suggest that stress may play a role in the onset and progression of these conditions.
In addition to its effects on the digestive system, stress can also lead to changes in appetite. It is not uncommon for people experiencing prolonged periods of stress to have either a decrease or an increase in appetite. In either case, it is important to maintain a healthy diet and be mindful of what and how much food you are consuming.
Finally, stress can also lead to changes in eating habits. People under stress may find themselves binge eating or turning to comfort foods as a way to cope with their feelings. However, it is important to be aware of these behaviors and take steps to address them in order to maintain a healthy lifestyle.
Immune System Responses to Stress
The immune system plays an important role in the body’s response to stress. When the body is undergoing stress, it produces various hormones that can affect the functioning of the immune system. In particular, cortisol and epinephrine, both of which are released during the stress response, have been found to suppress certain components of the immune system.
Immune system cells, called leukocytes, have been found to be especially affected by cortisol and epinephrine. These cells are involved in the body’s defense against pathogens, so a decrease in their activity can increase susceptibility to infection and disease. In addition, studies have shown that cortisol and epinephrine can reduce the production of certain cytokines by leukocytes, which are molecules involved in the body’s immune response.
Stress can also modify the activity of the innate immune system, which is the body’s first line of defense against infection. In response to stress, the innate immune system can become overactive or underactive. When underactive, it can lead to an increased risk for infection. On the other hand, when overactive, it can cause chronic inflammation, which can lead to a variety of health problems.
In summary, stress can have a significant impact on the functioning of the immune system. It can lead to changes in the production of hormones such as cortisol and epinephrine, which can then affect leukocytes and the body’s innate immune system. As a result, stress can increase the risk of infection and disease, as well as chronic inflammation.
Cognitive Effects of Stress
The release of cortisol can have a long-term effect on the brain. Over time, it can lead to structural changes in areas of the brain important for memory and learning. For example, studies have shown that chronically elevated levels of cortisol can reduce the size of the hippocampus. This is concerning, as the hippocampus is essential for memory formation and spatial navigation.
The release of epinephrine is also disruptive to our cognitive functioning. It increases heart rate and blood pressure, which can make it difficult to concentrate on tasks and think clearly. It also makes us more prone to emotional reactions, such as fear or aggression.
Stress can also lead to changes in our behavior. When we are under stress, we may become more impulsive and take risks that we wouldn’t normally take. We may also be more likely to engage in harmful behaviors, such as smoking or excessive drinking. These behaviors can further interfere with our cognitive functioning, leading to poor decision making and difficulty concentrating.
The good news is that there are ways to manage stress and its effects on our cognitive functioning. Some strategies include mindful meditation, exercise, and cognitive behavioral therapy. Taking steps to reduce stress and practice self-care can help to improve cognitive function and reduce the risk of long-term damage to the brain.
Behavioral Effects of Stress
These behavioral responses to stress are heavily impacted by the neurochemical changes that occur during this state. When the body is in a state of stress, neurochemicals like cortisol, epinephrine, and norepinephrine are released into the brain. These neurochemicals affect how people perceive and respond to stressful situations, making them more prone to becoming overwhelmed and anxious.
The release of these neurochemicals also has an effect on people’s thought processes. During periods of stress, people’s ability to think clearly is impaired, as their brains become focused on responding to the perceived threat rather than processing complex information. Additionally, people’s ability to concentrate and remember information can be greatly reduced. In extreme cases, people may even experience dissociation, which is a disconnection from reality.
Stress can also cause people to engage in risky behaviors, such as drug and alcohol use, gambling or overspending. These behaviors can lead to even more severe mental and physical health issues in the long run.
The behavioral effects of stress can be particularly hard to manage as they often occur suddenly and without warning. However, there are a number of strategies that can be used to help manage stress-related behaviors. These include mindfulness techniques, cognitive behavioral therapy (CBT), exercise, and relaxation techniques such as deep breathing or yoga. People should also ensure that they are getting adequate rest and nutrition, as this can help reduce the risk of developing serious mental health issues.
Emotional Effects of Stress
The psychological symptoms of stress can be divided into three main categories: cognitive, behavioral, and emotional.
Cognitive Effects of Stress
Cognitive effects of stress include difficulty concentrating, impaired memory, negative thinking, and difficulty making decisions. These symptoms can lead to decreased performance at work or school, as well as problems in personal relationships.
Behavioral Effects of Stress
The behavioral effects of stress include changes in eating habits, sleep patterns, and physical activity. People under extended periods of stress may engage in riskier behaviors such as substance abuse. They may also become more aggressive or withdraw from social activities.
Emotional Effects of Stress
The emotional effects of stress can range from mild feelings of sadness to intense feelings of fear or panic. People under prolonged periods of stress may experience feelings of hopelessness or despair. They may also have difficulty controlling their emotions and resort to outbursts of anger or aggression.
In summary, the emotional effects of stress can be significant and have long-term implications for an individual’s mental health. It is important to recognize the signs of stress and take measures to manage it in order to avoid developing more serious psychological issues.
The Impact of Long-Term Stress
Physical impact of long-term stress
Long-term exposure to stress can lead to a range of physical health problems. It can weaken the immune system, making it easier for illnesses like colds and flu to take hold. Stress can also cause headaches, muscle pain, digestive issues, and insomnia. It can also increase blood pressure, increasing the risk of heart attack or stroke.
Mental impact of long-term stress
The mental effects of prolonged stress can be even more damaging. Long-term exposure to stress can lead to depression and anxiety, as well as difficulty concentrating and making decisions. It can also lead to feelings of irritability and frustration, which can have a detrimental impact on both personal and professional relationships.
Managing long-term stress
The good news is that it is possible to manage long-term stress. It’s important to recognize the signs of stress and take steps to reduce the level of stress in your life. Exercise and relaxation techniques are one way to reduce stress levels. Talking to a therapist or counselor can also be beneficial, as they can help you identify the sources of your stress and develop coping strategies. It’s also important to get adequate rest and nutrition so that you’re better equipped to cope with stressful situations.
Management and Treatment of Stress
Most people find that lifestyle changes, such as better time management and increased physical activity, are useful for managing stress. Additionally, there are psychological techniques, such as mindfulness, cognitive restructuring, and relaxation techniques that can be used to manage stress.
Mindfulness
Mindfulness is a technique that involves paying attention on purpose, in the present moment, without judgement. It can help to increase our awareness of our own thoughts and feelings. It is important to note that we are not trying to judge or control these thoughts and feelings; rather, we are simply trying to observe them non-judgementally.
Cognitive Restructuring
Cognitive restructuring is a technique used to challenge and replace negative thought patterns with more positive ones. It involves identifying and changing irrational beliefs and thinking patterns that may lead to stress or anxiety. Identifying these thought patterns can help us gain insight into our own behaviour and our reactions to stressful situations.
Relaxation Techniques
Relaxation techniques such as yoga, tai chi, and meditation can be helpful in managing stress. These techniques help to reduce physical tension and relax the body, which in turn can reduce mental stress. Additionally, relaxation techniques can help us to become more mindful and aware of our own thoughts and feelings.
In summary, managing stress requires an understanding of the source of the stress and an implementation of coping strategies. Lifestyle changes such as time management and physical activity can be beneficial for managing stress. Additionally, psychological techniques such as mindfulness, cognitive restructuring, and relaxation techniques can be used to manage stress.
Conclusion: A Summary of the Biology of Stress
