Everyone knows they should exercise. Doctors, scientists and even ancient philosophers have long advised that exercise is good for you and warn that the more the better if done properly. Now we are getting more and more proof that exercise is critical.
Researchers have found that during and immediately after exercising, positive changes occur in our bodies. A steady run, jog or walk not only gets blood flowing and hearts pumping but also helps improve skin and eye health. If someone created a drug that could do for human health everything that exercise can, it would be the most valuable pharmaceutical ever.
So why do only 20 percent of Americans get the recommended 150 minutes of strength and cardiovascular physical activity per week? Why is it that more than half of all baby boomers do no exercise whatsoever? Surely by now everyone knows the consequences of leading sedentary life.
People with low levels of physical activity are at a higher risk of developing cancers, heart disease, Alzheimer’s and early death by many other preventable causes. Yet generally speaking, humans are not good at assessing long-term risks as well as benefits, of our lifestyle choices. Promises that exercise is “good for you” aren’t motivating enough for most people to take action — especially if they consider exercise as just another chore. However, most people are motivated by rewards. Here are only a few of them regarding proper exercise:
— Slower aging.
— Better mood.
— Less stress and anxiety.
— Less chronic pain.
— Improved eyesight.
— Lower medical bills.
Where’s the proof? Beginning in 2017, the U.S. National Institutes of Health (NIH) will launch a six-year $170 million study with a group of 3,000 sedentary people of all ages. They will start an exercise program and then donate their blood, muscle and fat before and after exercise. Another group that doesn’t exercise will also be tracked.
This study is the first of it’s kind in terms of size, rigor and aims. Experts are hoping it will give doctors evidence they need to start treating exercise like the miracle drug they’ve long thought it to be. Instead of your doctors saying, “You need to exercise more,” they will actually give exercise as a prescription!
It’s becoming evident too that nearly everyone — young, old, pregnant and those that are ill —benefit from exercise. As scientists learn more about why this it is, they are hoping that the messaging about exercise gets simpler too. No fancy gym membership required, just get out and move. I’ll have on this important subject next week. So please stay tuned!
