A Solution For Stress

Posted March 27, 2012 12:00 AM by Chelsey H
Pathfinder Tags: running stress

In upstate New York, the mild winter has left for an almost summer-like spring. The warmer weather has jump started the outside activities of summer-like running. Running (really all forms of exercise) has many benefits for your body and your mind. Although there is no clinical proof, exercise is a prescribed treatment for mild depression, anxiety, and stress. There have been links to cardio exercise increasing cardiovascular health, muscle tone, energy levels, and overall well-being. Any type of exercise can relieve stress and you can be of any fitness level to enjoy the benefits.

I touched a little bit on the danger of living with high stress in an earlier blog post. It can cause premature cell aging and a host of physiological and psychological symptoms. In an effort to present a unified theory on the effects of exercise, Peter Salmon at the University of Liverpool conducted a review of information on exercise and mental health. Using his findings and some other resources, I'll explain some of the direct stress-busting benefits.Image Credit

-Running increases endorphins. Endorphins are the body's "feel good" neurotransmitter responsible for the "runner's high." Runner's high is often described as a euphoric state resulting from long distance running. The neurotransmitters have also been linked to depression; an increase in endorphins from exercise has antidepressant and anxiolytic effects. (Endorphins are also released after taking many recreation drugs-but I'm hoping to get you addicted to exercise instead.)

-After a good workout it's common to find that you've forgotten the day's stressors since you were concentrating on your body's movements. You start to focus on a single task and the energy and optimism gained can help you remain calm and clear. Exercise releases norepinephrine, which increases heart rate and prepares the body for flight-or fight response. The depletion of norepinephrine has been linked to a chronic stress, but exercise has been shown to steadily increase the amount of the neurotransmitters resulting in a larger reserve of the chemical, so depletion caused by stress is less likely to occur.

- Exercising increases your self-confidence, and lowers the symptoms associated with mild depression and anxiety. Since you're more relaxed it's easier for you to sleep, which also reduces stress, depression and anxiety. Exercise can give you a sense of command over your body and your life.

Your body is physically designed to take stress in different ways. Running in sneakers can increase the stress and force on your feet. When you run or exercise in sneakers you tend to land on your heel causing a great collision force on the foot and leg. Running barefoot causes you to run more on your toes and you'll land on the forefront of your feet. A smaller part of the foot comes to s sudden stop and the natural spring-like motion of the foot and leg absorbs further shock. Sneaker designers are working on ways to make running more comfortable and more like running barefoot. The Vibram Fivefingers are the closest so far.

I don't suggest dropping everything and running a 5K after reading this article. You should increase your level of exercise gradually and start slow. If you spend all day sitting at your desk, you could start with working at a standing work station and/or having a walking meeting. Make sure you schedule it into your day because it is a priority. Also make sure that you like what you're doing. I've never really liked working out on gym equipment, so I have to trick myself into exercising by taking dance or cycling classes. As long as you're doing cardio for 30 minutes to an hour each day, what you're doing is less important than actually doing it.

Another tip: don't let exercise be a stressor. Set some goals for yourself and workout with an encouraging friend. The more accomplished and supported you feel, the more likely you'll continue to exercise and the less stressed out you'll be.

I've signed up for my first two 5K races so far this summer. Like I mentioned before, I've never really enjoyed working out but I'm hoping that having a goal and a definitive date to accomplish it by will keep me on track!

running on sneakers has nothing to do with walking on heels, it is a habit and can be unlearned.

I get "stressed out" when I see "stress" used as a negative; "stress" is neither negative or positive. There is satisfying stress when one works successfully while under pressure on something positive; an artist feels some stress while thoroughly enjoying the experience of painting or carving or...

  • "I get "stressed out" when I see "stress" used as a negative; "stress" is neither negative or positive. There is satisfying stress when one works successfully while under pressure on something positive;"

Your combining stress and pressure under the same heading. Pressure is when you are working hard but are in control of the situation stress is when you are NOT in control of the situation. For example flying an aircraft is a high pressure job with a heavy workload that in the event of emergencies requires split second decision making and a cool head. However, you rarely see pilots suffering from stress because they are in control of what is happening around them.

On the other had working in a position that has a low work load, but for the most part is out of your control due to poor management or management trying to micro‑manage everything you do and telling you how to do your job can be a very stressful environment.

Something else that's worth mentioning are those endorphins that the author mentions that cause a "runners high" or feeling of elation not unlike being medicated with opiate medications. This is because endorphins are chemically very close to opiates and can be just as addictive. They are there to protect you in a fight or flight situation where you are in pain that would otherwise slow you down or immobilize you. It's often called the pain barrier and is meant as the bodies last resort to escape a dangerous situation and is usually accompanied with a big dose of adrenalin.

However, pain is there for a reason, it's your body's way of saying stop what you are doing RIGHT NOW because you are causing damage to it.

To regularly push yourself through the pain barrier is definitely not a good thing as you not only run the risk of causing permanent damage but becoming addicted to the euphoric effect you get from the endorphins.

I used to work for a guy that was hooked on endorphins and he couldn't function unless he ran for around 5 km three times a day even when the temperature was above 40°C and he ran a serious risk of massive dehydration and severe sun burn.

Don't get me wrong, as the author suggested exercise is good for you, but like so many things in moderation, too much and you run the risk of injuries that may be permanent.

We will have to disagree, I am a structural engineer, if you load something (or somebody) you put it (or them) under stress. The fact that the person handling the stress is not hurt does not mean they are in the same condition as when sitting by the fire, reading a book with a favourite dog alongside.

You're equating the structural engineering interpretation of the word stress with the psychological term stress and believe me the psychological one is completely different and definitely not good for you in any way shape or form. Psychological stress raises blood pressure and heart rate, can mess with your digestive system, put added strain on the liver and kidneys, suppresses your immune system and increase the risk of contracting numerous forms of cancer.

A high pressure environment for example when you have tight but achievable deadlines does not equate to a stressful environment provided you have the tools both physically and mentally to perform what is expected of you, the necessary materials and are in control of the situation. In such a high pressure situation chances are you will not be stressed, will achieve what is required of you and feel good about the results and yourself when the job is completed.

However, remove any of the tools, make the deadline impossible to achieve or have some idiot manager cracking the whip and telling you how to do your job and you have the recipe for a stressful environment.

Two relatively similar situation but change just one of the parameters and a high pressure environment suddenly becomes stressful and if it continues your health will ultimately suffer from it. Believe me, I know as I have worked in both high pressure and stressful environments and they are completely different things and my health suffered seriously due to a stressful work environment.

Walking to get rid of stress may not be correct solution. To get rid of stress best exercise would be Meditation or Yoga. Wherein you control your mind and do breathing exercises. Walking is good to burn your calories but not for relaxing your mind.
