Do you usually feel the uncontrollable drowsiness after lunch? Some may think it is because they have been suffering from sleep deprivation. But do not worry, feeling sleepy after a finishing lunch is but normal due to the natural drop in body temperature. More over, scientists in their long lab coats have recently discovered a protein that significantly affects drowsiness. It's called hypocretin or orexin produced by the brain, and it helps keep a person awake.

Hypocretin works differently than leptin, the body chemical telling the brain that we are full or have eaten enough. With the full stomach and more leptin, hypocretin level lowers. Why? It is because leptin inhibits the production of hypocretin. To cut it short, the more leptin there is in the brain, the lesser the hypocretin and the greater the feeling of drowsiness. This is why some organizations suggest their members not to eat much during lunch time, just so they won't dose off.

While one cannot let himself dose off cannot in some important events, a recent study, brings midday nap one big step up. According to the study researcher Matthew Walker, PhD, an assistant professor of psychology at University of California, Berkeley, it helps with learning an in long-term memory consolidation. In countries, where people are allowed to take a siesta or sleep a little after lunch during workdays, are actually getting commercial benefit without knowing it.

More that commercial advantage, an afternoon siesta is definitely a healthful nap. While many experts believe that the ideal pattern is one long stretch of sleep every 24 hours, at an average of 8 to 10 hours, healthful nap still makes big difference. A short, midday nap of about 15 to 30 minutes may help restore alertness during the afternoon slump without throwing your longer sleep cycles out of rhythm. For people who suffer from sleep deprivation, a nap isn't enough. Visit a person in scrubs and uniforms and ask for medical advice or necessary medical attention.
