SLEEP AND WEIGHT
Did you know there is a possible link that is rising by each day?
If you have been a regular reader to this site, then you have learned by now that there are many links to your weight than you had ever previously imagined.
Today we will explore the links between the amount of sleep you get to gaining or losing weight.
There are certain things as listed in the above chart that show relationships between your rest and certain hormones in your body, and these hormones influence certain actions in the body.
We will look at 2 hormones LEPTIN and GHRELIN.
Doctors have established that both can influence our appetite.
The amount we sleep or don’t sleep has been shown, in studies, to affect the production of both these hormones.
Let’s examine the characteristics of both these hormones:
Ghrelin stimulates appetite , and is produced in the gastrointestinal tract.
When you do not get enough sleep your body reacts by increasing the levels of ghrelin, and this increases your appetite. As the levels rise higher, you feel the urge to eat more and more.
This increased eating creates a calorie abundance, which leads to more excess weight.
Ghrelin is akin to putting your foot on the accelerator for eating.
Leptin signals the brain when you are full, and is produced in fat cells.
When you do not get enough sleep your leptin levels decrease, this in turn stops your brain from receiving the signal that you are full and leads to over eating.
Leptin puts the brakes on your eating by creating a feeling of fullness.
When these two hormones are combined they cause a higher rate of people suffering from obesity.
In order to stabilize these hormones it is important that a person receives adequate rest. The norm that is still acceptable and recommended is at least 8-10 hours of restful sleep.
Sleep that is not restful (tossing and turning), light sleep, broken sleep is not considered adequate.
You need deep, rem (rapid eye movement) sleep.
Another problem with sleep deprivation is that people are usually more sedentary during the extra hours they spend not sleeping. They have a tendency to eat more during this time, and because of the high levels of ghrelin and low levels of leptin, they increase the incidences of obesity.
Leptin controls your feelings of being full and signals the body to stop eating.
Ghrelin controls your appetite by stimulating it.
Sleep deprivation increases gherin and decrease leptin.
It is important to get adequate rest, because it is one of the factors in controlling your weight.
