The number of different ways that exercise can increase life expectancy is nothing short of staggering. Over the last few decades, study after study has revealed just how much of an impact exercise, as well as a smart diet, can have on human health. In this article, we will examine some of the key ways that exercise can impact human health and even increase life expectancy.

Exercise Naturally Releases HGH
HGH, or human growth hormone, decreases as we age at a steady pace. By the time we are in our seventies and eighties, we are in fact producing very little HGH. One of the single best ways to naturally and safely keep HGH levels from dropping so dramatically is to keep exercising and stay fit. Those who exercise naturally increase their human growth hormone levels.

Exercise Increases Bone Density
You might not think about helping your level of bone density when you are exercising. Most people think about exercise and building muscle, but there is a very real connection between bone density and exercise. Exercise causes a reaction in bones, as bones respond to the weight load being placed upon them. The end result is far stronger and even denser bones. Why is this significant for life expectancy? Injuries and broken bones are one of the leading causes of failing health in the elderly due to falls.

Exercise is Good for Heart Health
You have likely heard that exercise is good for heart health. When it comes to longevity that is clearly a good thing. If you want to live longer, then you want to keep your pulse rate and blood pressure in an optimal range. When you improve your level of fitness, you are less likely to have a heart attack or issues with high blood pressure. Further, diabetes and cancer are less likely as well among those who exercise regularly.

Beat Stress with Exercise
Medical science has no doubt that exercise can play a role in beating stress. When you exercise, the stress hormones that damage your body and cause aging are released. As a result, they will end up causing less damage. Exercise is a good "de-stressor," as it makes you feel good and more relaxed and can lead to a longer life. Researchers have found that regular physical exercise can keep stress from reducing the length of the body’s telomeres. When the telomeres get shorter, health problems can occur.

Exercise is Good for Your Brain
Longevity and brain health most definitely go hand in hand. If you want to live a long time, you need your brain to be working well. Exercise has been proven to get more blood flowing to your brain, and that is a very good thing! Thus, exercise can keep your brain working effectively and, in the process, help you make better decisions as you age. This fact serves to help you stay in good health and stay alive longer.
