Laughter Is Good For Your Veins

It is frequently said that laughter is the best medicine, but did you know it is good for your veins? Scientists at the University of Maryland have proven that laughter is linked to healthy function of blood vessels. Laughter creates increased blood flow by causing the inner lining of blood vessels to expand. The lining of blood vessels, called the endothelium in medical "speak," has many jobs to perform aside from regulating blood flow. The endothelium adjusts coagulation and blood thickening as well as secretes substances that respond to wounds, infections and irritations. This lining is also where atherosclerosis, the hardening of the arteries, begins and this hardening can lead to cardiovascular disease.

So laughter helps keep the blood flowing, as if you needed another reason to read GiggleSugar.
