Now that you’re older, are you having a hard time tolerating summer heat? Especially when the humidity is high? Well, a new study shows that supplementing with a certain vitamin may be what you need to feel better in summer heat.
When you were a kid you could probably handle summer heat pretty well. You stayed out playing all day with your friends without a second thought. But, after age 50, you may have noticed that you don’t tolerate summer heat, especially high humidity, the way you used to.
In addition, summer heat waves also present an increased risk for heart attack and stroke in older people. A recent study out of Penn State University reveals that the two are related.
As you get older, your body’s blood vessels don’t have the same capacity to dilate the way they did when you were younger. That results in less blood flow getting to your heart, brain and your skin. That’s because you don’t produce the same amount of nitric oxide you did when you were younger.
The reason behind your lack of nitric oxide, and blood flow problems, could be a deficiency in folic acid that may older people have, says Penn State researchers. So, supplementing with extra folic acid in hot, humid weather can help decrease your risk for heart attack or stroke.
Folic acid is one of the B Vitamins which are essential for the good health and function of your heart and nervous system. It works in tandem with Vitamin B12 to decrease homocysteine levels that can lead to blood clots, heart attack and stroke.
Folic acid also helps your body produce nitric oxide which dilates blood vessels. Keeping blood flowing freely allows more blood to reach the skin which cools you down. It also reduces the chance of a clot forming and keeps blood flowing freely to your heart and brain.
Recent studies have also shown that it may help prevent Alzheimer’s disease and senile dementia. Its homocysteine lowering properties also fights the occurrence of mini-strokes that can lead to the development of dementia.
Older people are frequently deficient in folic acid, and the other B vitamins, from either a poor diet or from decreased absorption ability. But, you can get enough folic acid (folate) from many foods including fortified orange juice and cereals, broccoli, Brussels sprouts, chick peas, and brown rice.
You need about 1 mg of folic acid a day. But, as you get older, your ability to absorb nutrients from your foods decreases. So, it’s a good idea to also take digestive enzymes along with your B vitamins to ensure that you’re absorbing the amounts you’re taking.
As people get older, their ability to tolerate intense summer heat decreases. As the Penn State study shows, making sure you’re getting enough folic acid can help. There’s also some other tried and true ways that can help you like the following:
The proper balance of electrolytes is what keeps your major internal organs, heart, lungs, kidneys, brain functioning correctly. Sweating profusely can deplete electrolytes dramatically. Good choices are low sugar vegetable juices, like V-8, that are higher in sodium and potassium; low sugar lemonade, limeade or citrus juices which are higher in potassium; and lighter protein shakes that contain calcium, magnesium, potassium, and sodium.
Summer is right around the corner and higher temperatures and humidity are on their way. Learning ways to better handle the heat now can help you avoid getting sick, or having a cardiac event.
