There are so many different disorders that people face today, it is a wonder any of them get any normal sleep during normal sleeping time, or what is accustomed sleeping times.
The science world has been studying the brain's natural source of melatonin to create a synthetic form of the hormone that causes the body to get tired at night and wake up during the day.
This is called the circadian rhythm.
Many people have trouble experiencing that good night sleep that quite a few of us may take for granted.
These sleepless people may not sleep because of medical reasons, work-related reasons, physiological or mental reasons, and the list goes on.
Whatever a person may be facing to cause the lack of sleep, the scientists have developed a synthetic form of melatonin supplements, melatonin vitamins and even melatonin tablets to help the suffering have a good night's sleep.
Some of the people who have been tested with a melatonin sleep aid are elderly people over the age of fifty five.
The melatonin sleep aid has shown to aid them in improving their sleeping habits and helping them to awaken more alert in the mornings.
Another group of people with sleep disorders trying the melatonin sleep aid are those that suffer jet lag.
It is suggested that those who take the melatonin supplements on the day of travel, close to bedtime, and continued for several days, reduce the number of days required to produce a normal sleep pattern.
It seems to cut down on the amount of time it takes to fall asleep.
There has actually been some testing with children who have mental retardation, autism, epilepsy, psychiatric disorders, and visual impairments, has been carried out in melatonin supplements with some good results of falling asleep faster and sleeping longer periods of time.
The effects on children, however, will need to be further researched, before recommendations can be made.
Healthy people can benefit from a melatonin sleep aid as well.
They may take the melatonin supplement 30 to 60 minutes before bedtime and have a normal sleep time without waking and wake refreshed in the morning.
A precaution to taking the melatonin supplements, and that is that it can cause nightmares or vivid dreams in some cases.
Those are incidents that need to be further observed.
