Stressed Out:
A Body-Mind Connection

Did you grab this book because you’re stressed out? Maybe you feel stress when you think about all the homework you have to do or about pressure to get good grades. You may be so stressed about schoolwork that you put it off or don’t do it at all. And you know where that gets you!

For some people, school pressure can create panic attacks. One young woman experienced daily panic attacks that sometimes seemed to come out of nowhere. She would feel her heart beating very fast, and she would start to hyperventilate. She felt as if she was in danger, and she could focus only on the fear in her mind and her difficulty breathing. Everything else around her was a blur. Other people may experience a panic attack with light-headedness, nausea, physical agitation, chest tightness, hot or cold flashes, sweating, and racing thoughts. They might fear they will lose control or faint.

People commonly feel stress and anxiety when they cannot control their situations. If your family is in financial difficulty or your parents are going through a divorce, for example, you might feel stress every day. If you’re bullied or assaulted or picked on because of your race, religion, gender, or any other trait, you might have constant stress. Or maybe you or someone you care about has health problems that feel overwhelming. You aren’t sure how to cope. All of these very real issues can weigh you down and leave little room for calm or for happiness.

Stress in Your Body

When we talk about stress, we usually think of it as a negative. Neurologists and psychologists point out that the mind and body experience two types of stress: positive stress—called eustress—and negative stress, or distress. We experience both types through physical sensations.

Eustress is the body’s short-term psychological response to a positive, healthy stress such as getting excited and motivated for a game or performance. We can also experience eustress when we’re having fun riding a roller coaster, trying a new sport, or solving a puzzle. Eustress releases feel-good chemicals called endorphins in the brain. They give us energy and help us focus and perform better. And through eustress, we have a sense of fun or satisfaction. Just the right amount of stress is actually good for the brain too. Eustress can enhance the growth of neurons (nerve cells) in the hippocampus, a structure in the brain that forms memories.

Stress isn’t all bad. The excitement you might feel before competing in an athletic contest, for instance, is called eustress. It helps motivate you to do well. Distress, on the other hand, can lead to emotional and even physical pain.

But distress is not fun. When we are frightened, overwhelmed, or sad, we may experience distress as unpleasant physical sensations. Distress can trigger headaches, stomachaches, and muscle cramps. It can also cause restlessness and insomnia. Some people get so upset or nervous that they can’t eat or they throw up. What’s causing these symptoms?

The Stress Response

Neurobiological studies show that when people are exposed to a threat, their brain and body react with the fight-or-flight response. They physically prepare to either fight off the danger or to run from it. Imagine hiking up a mountain trail, and suddenly, you see a rattlesnake in front of you on the path, poised to strike. Your heart starts pounding, and your muscles tense up. Your stomach does flip-flops. Your body is getting ready to fight or flee.

NEURONS AND NEUROTRANSMITTERS

This infographic shows neurons in the brain, their major structures, and how they connect to one another. The spaces between neurons are called synapses. By crossing synapses, brain chemicals such as dopamine and serotonin travel from one neuron to the next.

The stress response begins in the brain. When you are in a stressful situation (such as an encounter with a rattlesnake), the body’s sense organs—the eyes and ears, in particular—pick up and send information to the amygdala, a structure in the brain that processes emotion. The amygdala then interprets the information and, sensing threat, sends signals to the hypothalamus, which helps control the body’s nervous system. The hypothalamus triggers the adrenal glands. These small structures on top of the kidneys release epinephrine (also known as adrenaline) into the bloodstream. This hormone is one of many chemicals that help our bodies function. In a fight-or-flight situation, epinephrine causes the heart to beat faster, pushing blood to the muscles and vital organs. Pulse and blood pressure go up, and breathing gets faster. Extra oxygen goes to the brain, which increases alertness. The pupils dilate (widen), which allows more light into the eyes for better vision. Also, the muscles tense up, making the body ready for action. The adrenal glands also secrete the hormone cortisol. It stimulates the breakdown of glycogen (a substance stored in the liver and muscles) into glucose, a sugar that fuels the body. This process gives the body energy. The person is ready to fight the danger or flee for safety.

The fight-or-flight response is an essential survival mechanism for humans. It was helpful in prehistoric times, when humans lived in small clans in the wild, fighting off animals and running for shelter from storms. This response is still helpful when we face danger. Maybe a fire starts in the kitchen, and you must react quickly to put out the flames. Or perhaps you’re riding a bike and have to swerve quickly to avoid a dog running into your path. This response in the brain happens so quickly that you may not be aware of it. People often react and escape danger before they realize what’s happening.

Stress without the Rattlesnake

The downside of this autonomic response to danger is that sometimes the body perceives a threat when there is no rattlesnake—a false alarm. Common situations such as taking an exam, speaking in public, or joining a new social group can cause this stress response. Some people feel distress in many other types of situations. They may feel stress throughout much of their day.

Chronic activation of the stress response can harm the body. When we’re scared or nervous, we sometimes take fast and shallow breaths. This can cause dizziness. In people who have asthma, it can trigger an asthma attack. Acute emotional stress can also increase the heart rate and, over time, damage the heart. Continuous overactivation of the nervous system can also cause high blood glucose levels, which is unhealthy for people with diabetes. It can also cause insomnia. Chronic stress can also cause changes in the brain that impair learning, memory, and mood.

Mindfulness can help. Research shows that mindfulness is associated with lower levels of cortisol and other stress hormones. Research also suggests that mindfulness helps people relax and manage chronic stress. Most scientists agree that more research is needed to fully understand how mindfulness interventions change the brain and body.

The following exercises are helpful in managing the physical symptoms experienced during distress. Try this one when you feel distress, no matter where you are:

Deep abdominal breathing engages the vagus nerve—a nerve that runs from the brain stem (a structure at the base of the brain) to the abdomen. Among other functions, the vagus nerve stimulates a relaxation response in your body. The next exercise adds body awareness to full belly breaths, which can pull your attention away from upsetting thoughts and focus it on your body and the place where you are.

For deeper relaxation, try this full body-scan exercise. You’ll want to find a quiet place to lie down.

When we are anxious, we might feel physically unbalanced—a little wobbly. A great way to counteract this feeling is with balancing exercises. The following one is a timed exercise, so use a kitchen timer or a smartphone timer:

Another way to calm your nervous system and find inner balance is with a yoga position called the child’s pose.

Pain

Physical pain is an interaction of sensory nerves, the spinal cord, and the brain. Without the ability to feel physical pain, you wouldn’t pull your hand away from a hot stove or know when you had injured yourself. So you could say that physical pain is a valuable response to tissue damage to your body.

But physical pain is unpleasant, and sometimes it’s so great that you can’t think of anything else. You might obsess about the pain, worrying that it’s not going away or that it’s signaling a more serious health problem. Worrying about pain adds emotional suffering to physical suffering. And emotional suffering can make the physical situation worse. Physical pain and emotional suffering activate the same areas of the brain—the anterior insula and the anterior cingulate cortex. So sometimes it’s hard to figure out how much something hurts physically, hurts emotionally, or both.

Whenever you feel physical pain—such as a headache—try this exercise to determine the difference between your physical sensations of pain and your emotional suffering. Remember, though, that this exercise is for becoming more aware of your body and emotions. It is not a substitute for medical care. If your physical pain is acute or it continues, seek medical attention.

This exercise might help interrupt the stress response and lessen your emotional pain. By working through or letting go of your emotional suffering, you might even be able to reduce your physical pain.
