6 Types Of People At Risk For Blood Clots

Blood clots aren't always a bad thing. When you cut yourself, your blood cells are supposed to clump together, which stops blood from leaking to places where it doesn't belong and kicks off the healing process. But sometimes clots form in places they shouldn't, and if they occur in a location where blood needs to keep flowing, that can spell trouble.

There are several major types of clots that can cause problems. Clots that block blood to your brain cause stroke, and ones that stop up your heart’s blood flow cause a heart attack. A clot that forms in your leg is called a deep vein thrombosis (DVT). DVTs can break away from their starting place and travel to your lungs. This is called a pulmonary embolism (PE), and can be very serious, even fatal.

Why Some People Sweat More Than Others

Some people sweat more than others. Exercise with a group, and the differences become obvious.

But what determines these variations?

Answers have traditionally focused on factors like body fat percentage (more fat insulates you and makes you overheat sooner) and aerobic fitness (the fitter you are the less you sweat).

At the American College of Sports Medicine meeting this spring, Matthew Cramer of the University of Ottawa and Ollie Jay of the University of Sydney presented some results that challenged those ideas. That data has now been published in the Journal of Applied Physiology, and it has some surprising twists.

The problem with previous studies is that body fat and aerobic fitness (VO2 max) tend to correlate with other factors. People with lots of body fat tend to weigh more—so is it the insulative properties of fat that matter, or is it simply being bigger and having to haul around more weight?
