âReinstating the draft and requiring women to register for the Selective Service would compel the American public to have a stake in the wars we fight as a nation. We must question why and how we go to war, and who decides to send our men and women into harmâs way.â.ep. Charlie Rangel (D-NY) wants all Americans to serve their government, including women. On Friday he introduced one bill that would reinstate the draft and another that would require all women to register for Selective Service as well.
Answers from Sheldon G. Sheps, M.D. Caffeine can cause a short, but dramatic increase in your blood pressure, even if you don't have high blood pressure. It's unclear what causes this spike in blood pressure. Some researchers believe that caffeine could block a hormone that helps keep your arteries widened. Others think that caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase.
However, this increased activity can also cause blood vessel constriction, which may increase blood pressure and alter the supply of blood to the heart. In fact, most of the dangerous effects of strong stimulants like cocaine and methamphetamine are a direct result of their activity on blood vessels and the heart. Because caffeine is a stimulant, there is a good reason to suspect that coffee and high blood pressure might be related. Caffeine, though, is a very mild stimulant and has a short lifespan in the body. Caffeine is also a self-limiting stimulant because it acts on the kidneys to increase the rate of its own excretion.
