Sleep and hormones that affect weight

Lack of sleep can eliminate the hormone that regulates appetite. As a result, the desire to eat high-fat and carbohydrates will increase.

What I mean here are two kinds of hormones in our bodies, namely leptin and ghrelin, both of which affect our appetite. Michael Breus, PhD, a faculty member of the Atlanta School of Sleep Medicine and director of The Sleep Disorders Centers of Southeastern Lung Care in Atlanta explained that Leptin and ghrelin work in a kind of "checks and balances" system to control our feelings of hunger and satiety.

Scientists have uncovered an inverse relationship between the hours of sleep and blood plasma concentrations of ghrelin; as the hours of sleep increase, ghrelin concentrations were considerably lower, thereby potentially reducing appetite and avoiding potential obesity.

Not enough sleep for 2 nights can trigger excessive hunger. This condition occurs because the hormone ghrelin stimulates appetite enhancer and reduces leptin as an appetite suppressant. When leptin levels down, you will not feel satisfied after you eat. Even you will feel you need more food because of the hormone ghrelin increases.

What Is The Minimum Sleep Required By A Person?
Although this can vary from one person to another, ideally you should get a minimum of 7.5 hours of sleep every night, while getting 8 or even 9 hours continuous sleep is much preferable.

But in reality most of us sleep less as we get older. Perhaps this is one of the factors that led many elderly people become overweight easily.

If you are encountering consistent problems in falling asleep at night and are unable to cure your insomnia in spite of putting in your best efforts, you should soon pay a visit to the doctor. After evaluating you as a victim of the sleep disorder insomnia, the physician may prescribe sleep aid pills such as Ambien, Lunesta et al for you but to extract maximum benefits from the sleep aid pill, it is to be taken as per the instructions of the doctor. However, before you move ahead to treat your insomnia with Ambien, it would be considerably beneficial for you to obtain first hand information on Ambien from the website
