Healthy young and middle-aged adults usually secrete about 5 to 25 micrograms of melatonin each night - at least 80 times less than is in the commonly sold 2 milligram (mg.) tablet or capsule. The amount of melatonin the body secretes tends to decline with age, a possible link with an age-related rise in difficulty sleeping.

Melatonin regulates biological rhythms such as the sleep/wake cycle. It also acts as an antioxidant, protecting cells from damage caused by free radicals, the toxic by-products of normal cell metabolism.* Melatonin is one of the most useful and versatile substances produced in the body.

As we age our bodies produce less and less melatonin so that by age 45, most people produce less than half the melatonin they produced at age 20. This reduction in melatonin can make restful sleep more difficult to achieve. Dietary supplementation with MELATONEX can help to restore the melatonin we need for restful, natural sleep.*

Testosterone is produced in the testes (gonads, balls, testicles) from progesterone and other precursors (androgen, DHEA, etc.) which are all products of cholesterol. (See diagram below). For this reason they are all called "sterols". When signaled by the pituitary gland in the brain via luteinizing hormone (LH), the testes, in the presence of adequate precursors, produce Testosterone.

The secretion of melatonin follows a daily rhythm governed by the body's master clock. This clock is located in the brain and is synchronized by regular exposure to the 24-hour cycle of darkness and light. Melatonin secretion may serve as a biological time cue. Although its natural secretion in the body peaks at night, melatonin does not control sleep. If it did, night workers would not be able to sleep in the daytime when melatonin levels are low.

Cortisol is a stress hormone. Your body produces cortisol in response to stress, physical, mental or emotional. This can include extremely low calorie diets, intense training, high volume training, lack of quality sleep as well as common daily stresses such as job pressures, fights with your spouse or being caught in a traffic jam.

Melatonin has a rapid, mild sleepiness-inducing effect. Because of this trait, properly timed melatonin supplements may help people adapt to changes in sleep-wake schedules, as may occur after jet travel across many time zones or in shift work. The effectiveness of melatonin for relieving insomnia is uncertain. Many concerns remain about melatonin's safety, especially for long-term use.

Mother Nature has not abandoned us nor made a mistake with our generation. Our foods, drugs, environmental pollutants and profit driven medical industries have brought on many of our ills. Progesterone deficiency, more specifically estrogen dominance (as Dr. Lee refers to it) is an unfortunate condition of industrialized countries. Since 1948 over 70,000 new made-made chemicals have been introduced into our environment, less than 3% have even been tested for toxicity.

The effect produced by the applicator-roller is equal to that produced by the applicator-plate, but the result is achieved much quicker. Besides, with the roller you can reach any place of the body. It is possible to work up the whole body with the roller for 2-3 minutes: the body will "burn", you will have "needle shower" consisting of a few millions of pricks. Using the roller, it is possible to warm the whole family after supercooling in 10 minutes.

The amount of electricity produced by the Acuscope is measured in microamps (millionths of an amp), an extremely tiny amount of current in comparison to the amount of electricity flowing from a wall socket. It has been scientifically proven that this level of current produces the most beneficial effect on the body's cells.

Just clean air. The Austin Air Cleaner does NOT produce OZONE, IONS, or NEGATIVE IONS. Ozone is active Oxygen and can be dangerous to people with respiratory problems, such as asthma and emphysema. Periodic vacumming of the four sides on the outside screen is the only maintenance required for the Austin Air Cleaner. Typically, the filter only needs to be changed every five years.

It produces XHTML compatible with the XHTML 1.0 specification. A cascading stylesheet is required for proper viewing with a modern graphical browser. Correct rendering of the HTML produced depends on the CSS support of the browser. A general-purpose stylesheet, html4css1.css is provided with the code, and is embedded by default. It is installed in the "writers/html4css1/" subdirectory within the Docutils package.

Following a vasectomy, the testicles will decrease the number of sperm that they produce. Second, the body will increase the process of sperm breakdown and reabsorption. Over a period of time, the equilibrium between sperm production and sperm reabsorption is fine tuned.

Moderate exposure to sunlight is the only way to help the body manufacture the vitamin D it needs. While eating salmon or mackerel and drinking fortified milk or juices is a step in the right direction, it is practically impossible to consume enough of these products each day to obtain the required amount of vitamin D through diet alone.

Nicotine is processed very quickly- it will exit your body within a day of its consumption. However, this rapid metabolism also causes nicotine withdrawal symptoms to start the day you quit. Fortunately, these symptoms can be controlled with nicotine replacement therapy or will resolve on their own within a week.

The endocrine system stimulates all of the systems and organs in your body. The hormones produced by this system amongst many other benefits increases your metabolism, helping to break down fat, build proteins, and create lean muscle. Because it affects almost all of the different systems of the body, it is this body system that we refer to as the "fountain of youth system" due to its youth-promoting benefits when optimally functioning. Consider it the body's "master bodily system.

Too much lead can harm both children and adults. No one knows exactly how much lead it takes to cause health problems. Many times there are no symptoms until the health problems are very serious. Usually people who are lead poisoned do not seem to be sick. Lead poisoning can cause learning, behavior and health problems in young children. Lead can cause high blood pressure and kidney damage in adults.
