The human body cools itself by increasing blood flow to surface areas and by sweating. When these cooling responses fail, the result may be heat-related injuries such as heat stroke or even death. Although the consequences of impaired heat loss are known, the complex networks that increase skin blood flow during heat stress are not well understood. Now, however, a new study identifies one type of histamine receptor as a key regulator of body temperature.

Now, researchers report that the obstruction of air passages that makes a person snore heavily or snort while sleeping can sharply reduce blood flow to the brain, possibly boosting the risk of stroke.
