On the contrary, the results of the US study of 70,000 women, which lasted 16 years, shows that the risk of gain weight in those who spend only five hours of sleep a day is 32%, which is 15% higher than those, who sleep seven hours.

In order to operate full the organism and its systems to function properly, it needs a healthy lifestyle, which includes the required amount of sleep.

When there is insufficient sleep the main danger to health is the development of cardiovascular disease.

This, of course, is related to the delay of all metabolic processes in the body which as a result leads to weight gain. The bad news does not stop here. Insufficient sleep releases cortisol – the stress hormone whose effect is testing hunger by waking organism.

According to the American Association of Sleep, chronic sleep deprivation seriously affect the metabolism of the body worsens overall health and add the extra weight.

It is possible to develop resistance to insulin, which increases the risk of developing diabetes. Furthermore, insomnia reduces the level of growth hormone that regulates the ratio of fat and muscle in the body.

Lack of sleep has an effect on blood pressure as it increases, which is a precondition for cardiovascular disease.

Sleep, hormones, and overweight

Studies on the relationship between lack of sleep and the weight gain concluded that sleep deprivation affects the synthesis of ghrelin and leptin, which are responsible for hunger and the feeling of satiety. To put it simply: leptin suppresses appetite ghrelin stimulate it.

When the balance between ghrelin and leptin diverges, there is a constant feeling of hunger, which can hardly be controlled no matter the amounts of food you have eaten.

When sleep deprivation becomes a chronic problem, the level of ghrelin rises and leptin – falls. This already leads to “ravenous hunger”. The result is clear – weight gain due to overeating.

The first step in order to stop the weight gain and lose weight is to identify the reasons for the sleep disorders. They usually have a rapid treatment. To improve the quality of sleep is necessary to increase physical activity, reduce the consumption of alcohol and caffeine.

There are cases where lack of sleep is associated with health problems such as enlarged tonsils, nasal congestion that prevents the normal airflow.

Medications that are used in sleep disorders have side effect like gain weight, which should be discussed with your doctor.
