The Science of Sweat

Rising temperatures mean a little more sweat than usual. Here’s the science behind it.

Our sweat glands spring into action under several circumstances. Rising temperatures, emotional distress, good old-fashioned exercise and even tongue sizzling spices can cause perspiration. This sometimes stinky reaction, plays an important health role, because it helps maintain body temperature by cooling us down.

Live long and perspire
Whether you’re a heavy “sweater” or someone who merely glistens, hydration is crucial during these extra sweaty summer months. Keeping the body hydrated helps the heart pump blood more easily through the blood vessels to the muscles. And, it helps the muscles work more efficiently.

You should sweat the big stuff
While sweating is perfectly natural and even extremely helpful, too much of a good thing still applies. Judging what constitutes excessive sweating varies from person to person but could be a sign of heat exhaustion or another medical condition. Always talk to your doctor about your questions and concerns.

Is your deodorant dangerous?
An aluminum-based ingredient in antiperspirants has been causing a lot of buzz recently. What’s all the fuss about and should you be worried? The answer is no, not really. Though some studies claim to link aluminum-based antiperspirants and deodorants to everything from breast cancer to Alzheimer’s, there is no real scientific evidence that aluminum or any of the other ingredients in your deodorant products pose any threat to human health.
