The human pineal gland manufactures the original sleep aid, melatonin (derived from serotonin), to put us into sleep. Although the pineal gland and its melatonin do not create our circadian rhythm, they act on it by increasing activity and levels, respectively, from a higher source of instructions, which is of course the brain.
Melatoninâ€”the original hypnotic
The pineal gland is an endocrine gland that secretes melatonin, a hormone, into the blood and, more importantly, the cerebrospinal fluid (CSF). The melatonin in the blood is ten times higher at night than in the daytime blood.
Melatonin begins to be made during an infant’s 3rd to 4th month of age, when sleep patterns begin consolidating at nighttime.
Synthetic melatonin, a sleep-aid, has been shown to affect the circadian rhythm, but before going out to buy it, know that melatonin’s receptor sites become desensitized (less stimulated by melatonin) in larger doses.

Aside from the common cold, irritable bowel syndrome (IBS) is the most common reason people miss work. 10-20% of people have it, and women are twice as likely as men to have it; however, only 15% of IBS sufferers actually seek medical help.

As such, IBS is called a functional bowel disorder. Although all the tissue is normal, there is an abnormality in the amount or the synchrony of the normal functioning. IBS’s exact nature is still being investigated, but it has proven to be an elusive disease to diagnosticians and scientists alike.
What causes IBS?
The exact cause is unknown. A number of theories have been proposed, but it is unlikely that any one of them is the cause; instead, it is more likely that IBS is caused by a confederation of causes that vary in terms of their influence on the gastrointestina ...
