The human body responds to stress with a powerful fight-or-flight reaction. Hormone surge through the body, causing the heart to pump faster and sending extra supplies of energy into the bloodstream. For much of human history, this emergency response system was useful: It enabled people to survive immediate physical threats, like an attack from a wild animal. But today, the stress in most people's lives comes from the more psychological and seemingly endless pressures of modern life. Daily challenges like a long commute or a difficult boss can turn on the stress hormones -- and because these conditions don't go away, the hormones don't shut off.  Instead of helping you survive, this kind of stress response can actually make you sick.

Chronic stress can harm the body in several ways. The stress hormone cortisol, for instance, has been linked to an increase in fat around organs, known as visceral fat. The accumulation of visceral fat is dangerous, since these fat cells actively secrete hormones that can disrupt the functioning of the liver, pancreas and brain, causing problems such as insulin resistanceinflammation and metabolic syndrome. Chronic exposure to other stress hormones can also weaken the immune system and even change the structure of chromosomes.

How Stress Affects the Brain

Recent research suggests that chronic stress takes a toll on the brain, too. Studies on mice show that stress-related hormones alter physical structures in the brain in ways that could affect memory, learning and mood. Some of these changes involve dendrites -- tiny branch-like structures on nerve cells that send and receive signals. Several studies have shown that stress hormones can shrink dendrites and, as a result, information doesn't get relayed across nerve cells. When the cell damage occurs in a part of the brain called the hippocampus, it can impact memory and learning.

If stress makes you feel anxious, damage to dendrites might be part of the cause. A 2011 study found that rats whose dendrites had eroded due to stress had higher levels of anxiety. More research is needed to determine the exact effect of stress hormones on people's brains, but one study of adults with post-traumatic stress disorder suggests that the stress hormone cortisol may actually shrink the size of the hippocampus. Researchers are still trying to determine if this is because of the hormone's toxic effect on neurons or if there is a genetic component -- or if both are involved.

Another part of the brain that seems to be affected by stress is the amygdala -- the part of the brain that regulates fear and other emotions. A 2003 study found that in mice under stress, the amygdala grew larger while the dendrites in the hippocampus shrank. Researchers believe that together, these two effects may cause an increase in anxiety. They think that as the amygdala grows in size, you may experience more anxiety and fear. (The amygdala is known to become bigger and more active in people who are depressed). But because the hippocampus cells involved in memory are shrinking and not transmitting information effectively, you can't connect the feelings of fear to memories of real events. You're left with a lot of generalized anxiety.

Tips On Coping With Stress 

If this news about stress and the brain is giving you a headache -- or stressing you out in other ways -- relax. The good news is that you can learn healthy ways to cope with stress that will protect your brain -- and the rest of your body -- from stress's negative effects.

Not everyone is equally vulnerable to stress. Genetics play a role in how a person's body reacts. Your past experiences can affect your response, too. If you lived through a lot of stressful situations growing up, you may be more sensitive to stress as an adult. Try to notice your own reactions to stress. Do you stay calm when pressures mount, or can you feel your pulse increase just thinking about a stressful situation? Once you become aware of what sets off your body's fight or flight response, you can use these tips to try to change your response to stress.

1. Resolve the stressful situation if you can. You may not have much control over many of the sources of stress in your life, but if there is a something you can do to resolve a stressful situation, do it! Talk to friends about what you can do to change a bad situation, and consider getting help from a conflict resolution expert if necessary.

2. Spend time with loved ones and cultivate healthy friendships. Research shows that a good social support network has definite mental health benefits. It can keep you from feeling lonely, isolated or inadequate and if you feel good about yourself, you can deal with stress better. Friends and loved ones can be a good source of advice and suggest new ways of handling problems. But they can also be an excellent distraction from what's bothering you. If your network of friends is small, think about volunteering, joining an outdoor activities group or trying an online meet-up group to make new friends.

3. Do an activity you like. Part of being stressed out is feeling that you never have enough time, so adding more activities to your schedule might seem like the last thing you need. But if you make even a little bit of time for an activity you really enjoy, the payoff can be huge: You feel calmer and happier and can deal with work and other demands better. Whether it's playing music, doing a craft, or working on your car, do something that absorbs and relaxes you.

4. Try relaxation techniques. Meditation, yoga, and tai chi can help slow your breathing and heart rate and focus your mind inward, away from whatever is causing you stress.

5. Exercise regularly. Whether it's walking outside with a friend or taking an exercise class at the gym, getting active can help you relax and help turn off your body's stress response.

6. Get plenty of sleep. When you're well-rested, you can approach stressful situations more calmly.

7. Eat a healthy diet. Stress is tough enough on your body, so help it out by feeding it fresh fruits and vegetables and low-fat protein.

8. Appreciate what's good in your life. It sounds corny, but focusing your thoughts on positive parts of your life instead of the stress-ridden areas can be good for your physical health. Research shows that positive emotions helped people recover their normal heart rate more quickly after it was raised during exertion.

9. Laugh! Researchers are still investigating the precise effects of laughter on stress hormones, but some findings suggest that it has a stress-relief effect on heart rate, respiratory rate and muscle tension. Your own research has probably convinced you that laughing makes you feel better.

10. Seek professional counseling if necessary.  Extreme chronic stress is no laughing matter. Enlist the help of a professional if you think you are at risk for serious health effects.

Wonderful post. I personally have experienced a prolonged stress response in my brain and body. It is amazing the difference in your mind and body once you start doing basic things to handle your stress.

I am glad you finished up the article with the stress relievers that I know and value. This last month has been particularily stressful in many unusual unexpected ways. I was noticed I was getting stressed... no kidding, reading about the damage over-stressing can do to the brain. Way over reacting from being continually over-stressed.
The Tips on Coping with Stress list put my mental feet back on the ground. Thanks.

Loved this article.
I am always stressed and sometimes over the smallest things. Lately my stress has cause me to feel sick, my blood pressure has gone up and I have really bad anxiety. I only 24 yrs old. I try and relax but it is the hardest thing to do.

Great article. I really love the positive suggestions for coping with chronic stress.

While all of the approaches mentioned could be helpful for anyone who wants to live a positive and healthy lifestyle, sometimes it is necessary to try other approaches if you have experienced very traumatic stressful events, like combat. Most health care providers or mental health providers can review various treatment options based on your symptoms.

www.stressandhealthonline.com provides information about stress, health, and stress management techniques like exercise and meditation.

Thank you for mentioning meditation.
A recent study showed the exact opposite affect on the brain from mediation, growth of the hippocampus and shrinkage of the amydala.

Excellent posting Deepak, agree strongly with your premises. I know from personal experience that stress can virutally disable our ability to function, to concentrate, to focus and to perform in a suitable manner. Stress can, and will, dramatically affect the brain, but, I also know from personal observation that the removal of stress, and, substituting positive feelings, deep relaxation and proactive behavior can undo the damage of stress on our brain, and, (I believe), on our body as well. The brain, at any age, can regenerate, rejuvenate, grow new connections, and, become more efficient AND more effective.

eh, so you want to know how to handle stress? Ask people who REALLY have been under stress (the likes of which 98% of you have never seen I'm betting):

It was like every day you had to look behind your back... every single second you had to -you had to walk really fast -you had to make sure you knew who was around you -make sure you knew everything -pimps were after you, other girls were after you, tricks... and you couldn't trust them..."

Does anyone know of some good meditation tips?
12:24 AM on 07/25/2011
The best meditation program , with many studies to back it up, for me and thousands of others is transendental meditation. I have met only a few people who felt it did not work for them. A simple twenty minutes twice a day. They have a slideing fee and anyone who truly wants to learn will be accomidated.

IMO, the basic act of focus on the breath is an extremely efficient way to bring about a cessation of stressful thinking, or thought for that matter. If there is one thing I have learned about meditation, it is that focus on anything other than oneself distracts one from just that, oneself, the self of course being the root of stressful thinking.

well, remember TO breath has been a common suggestion to anyone during a panic attack, but different forms of meditation have different ways of doing things.

With TM, there is no attempt to distract you from yourself, for example, and yet the effects of 8 weeks of TM practice on people with PTSD are quite remarkable: 50% reduction of symptoms.

I was in VN 12/66-7/69 as strung in I-Corp. Wounded several times the last time severly. I wet from there to a military hospital for six months to get 'well" the first time back with the people I knew before the war was something. One young lady said to me " god you have changed" this haunted me and still does. Constant alert does change ones brain. Some have extremes in changes others kind of just cope. I do not remember what I was like before the war, I know I had friends, played sports, and was a good kid. you will see when I post to those who harp on fear to stop, because being on constant alert ( stressed) will make you change. I hope this clear to all. P.S. I follow a rule do not harm yourself or others, this really two rules but if you harm yourself you harm others if your harm others you harm yourself.m

We tend to see stress as coming from others, wanting... asking....demanding...
Actually, stress comes from within ourselves. It is how we react to events.
My safety valve in stressful situations that seem to want to build is a thought
that I repeat to myself a couple of times before opening my mouth. Its simply
'I will only respond to constructive comments or criticism or ........', whatever.
This tends to throw the situation into a different perspective and I begin to
'observe' the situation rather than participate in it. I look for comments that I,
or we, can build on to come to an understanding. Works for me.
Thanks for the article.

that's great advice for everyday life because if we guide ourselves by external stresses, we'll never be free of them.

When I feel stressed from reading the depressing news and blogging, I switch to Solitaire on the computer. Relaxing even when you don't win. And you can't cheat!

Let's all of us do our best to stay in tune with what our bodies are telling us. Are we hungry. Are we tired. Do we need to talk to someone. Identify what it is and give this to ourselves. Help others and through this we will be helping ourselves in the long run.
