Melatonin and Sleep

Melatonin
Melatonin is a hormone produced by the pineal gland and has an significant role in circadian rhythms. The daily rhythm of melatonin secretion is controlled by a built-in, free-running pacemaker, the suprachiasmatic nucleus , and is synthesized from the amino acid tryptophan. Melatonin synthesis is controlled by contact with cycles of light and dark, and occurs independently of sleep.

Melatonin promotes sleep and its secretion increases when takes place the onset of darkness, helping to keep us asleep at night. Melatonin production usually peaks between midnight and 2am, then starts to fall and is low during the day. It also helps decrease core body temperature, which helps induce sleep. However, sleep is possible even when melatonin levels are low. People who have their pineal gland removed have only negligible disruption in sleep.


Laboratory experiments have shown that melatonin has antioxidant effects and suppresses the growth of some cancer cells. Laboratory researches also show it has anti-inflammatory effects. When melatonin is administered as a drug it has been proved to decrease levels of the female hormones progesterone and estradiol. It also enhances the secretion of prolactin (hormone produced by the pituitary gland). Melatonin may decrease the sensitivity of the body to insulin, which can raise blood sugar levels.

Abs Will Help You Live Longer

Abs
Many studies show that the people with the largest waist sizes have the most risk of acquiring dangerous disease. The proof couldn’t be more convincing. According to the National Institutes of Health, a waistline larger than 40 inches for men may lead to heart disease and diabetes. Another study concluded that for maximum health, a man needs to keep his waist size at no more than 35 inches. When your waist grows larger than 35 inches, you’re at higher danger of developing two or more risk factors for heart disease. And when researchers examined a series of data in this sphere they discovered that men whose waists measured more than 36.8 inches had a significantly elevated risk for myocardial infarction, or heart attack, in which an area of the heart muscle dies or is totally damaged by a lack of bloodflow. Men with the biggest bellies were at 60 percent higher risk. It is alarming because the average American man’s waist size is a ponderous 38.8 inches, up from 37.5 in 1988..A woman with a flabby midsection is as well at increased risk for the same health problems. And American women have seen their weight rise just as men have.

Of course, abs don’t guarantee you a general health, but studies show that by developing a strong abdominal section, you’ll reduce body fat and considerably cut the risk factors associated with many disorders, not just heart disease. For example, there is a 33% incidence of cancer among obese persons.
