According to many studies, people who sleep the least tend to gain more weight.
According to one of these studies, conducted over six years by researchers studying obesity at Laval University in Quebec City, it was established that people who slept five to six hours per night as well as those who slept an average of 9 at 10 hours gained more weight during the follow-up period than those who had slept an average of seven to eight hours, as recommended.
This study, published in the journal Sleep, corroborates a number of recent scientific articles which suggest that a U-shaped relationship may exist between sleep duration and body mass index, with the weight / height ratio serving distinguish between healthy weight and overweight.
According to Donna Arand, an experimental psychologist at the Sleep Disorders Center at Kettering Hospital in Dayton, Ohio, if you get seven to eight hours of sleep a night, you have a better chance of not gaining weight and keeping your weight off.
And if you get a lot less or a lot of sleep, you are harming yourself and having a hard time keeping weight off.
According to Angelo Tremblay, holder of the Canada Research Chair in physical activity, nutrition and energy balance, lack of sleep disturbs the production of hormones that control appetite. Lack of sleep seems to increase the production of ghrelin, the hormone that signals hunger, and a decrease in production of leptin, the hormone that informs us that we are full.
To explain the fact that a surplus of sleep would create the same problem as a lack, the researcher points out that great sleepers are in fact people whose sleep is of poorer quality. This explains why they stay in bed longer, to make up for their lack of sleep.
It would therefore seem that diet and physical activity are not the only factors to take into account. Rest is also an important part of maintaining a healthy weight.
This important aspect of weight loss was already part of the weight loss program developed in the Psycho Center in the 1970s.
Marcel Rouet, the creator of the method “lose weight through nervous relaxation *” applied exclusively in the Psycho Center, wrote: “sleep eliminates the toxins of fatigue accumulated during daytime activity. Also too little sleep , a night’s rest interspersed with awakenings, superficial or agitated does not allow to eliminate these toxins which end up accumulating … If you sleep badly, it is only by the control of the relaxation associated with the detoxifying overbreathing that you can find, in a few weeks, often in a few days, a calm, deep and restorative sleep. It is enough that the muscles and the nerves are relaxed when you sleep, that you have cleared your mind so that immediately you fall asleep soundly “.
We see it today, science established a relationship between sleep and weight loss, through hormonal action. The techniques applied by the Psycho Center also act on the endocrine mechanisms of hunger and appetite.
