You’ve probably heard or read that eating less can help you live longer. I had, too, but never with a good explanation of just why that would be. It turns out that medical researchers didn’t really know why, but now they think they do.

According to the Wall Street Journal, medical researchers have found that high doses of progesterone can prevent permanent brain damage and speed recovery if administered as soon as possible after a brain injury.

Progesterone, a female hormone associated with pregnancy, is known to protect the fetus and aid in brain and nerve development. Only recently have researchers discovered that it helps protect and heal adults, too.

Approval of progesterone as a medical treatmen is still 6 or 7 years away. But already researchers are making startling new discoveries. Immediately administering high doses of progesterone may also stop damage and speed recovery for stroke victims.

Noise really does harm your health. New medical research shows what we all know intuitively.

Many cities have banned the so-called “boombox cars” with huge speakers that dominate the whole neighborhood with sound. That is, the laws say the sound of your stereo should not be heard more than 50 feet from your car. Some cities have also banned the use of subwoofers, the subsonic speakers that make your windows vibrate and can cause structural damage to buildings.

The laws are a good idea, but it is hard to get them enforced. Apparently most police officers either disagree with the laws or consider them too trivial to bother with.

Earlier studies had shown that the human brain can cope with only three noise sources, and only for a short time. Concentration is impaired, and eventually the brain just shuts down, and we can no longer think. It’s not just being “overly sensitive,” though some are more affected by sound than others. It is a physical process that we need to be aware of.

Researchers have now found that continous or repeated noise over 50 decibels can damage your heart.
