The last meal of the day, the darkness and temperature in the bedroom, as well as the time spent asleep, all influence metabolism and digestion. By controlling these factors, you can help your body stay in shape.

Do you dream of losing weight without making any effort? Here’s how to help your body burn extra calories while you sleep.

The meal

If you eat a large meal shortly before going to bed, it will take a long time for your body to digest it . During the deep sleep phase, the brain releases a growth hormone. By eating late at night, this hormone will store the foods that are in the digestive system as fat instead of fuel . The same goes for alcohol : consumed shortly before bedtime, the body will work to metabolize it during sleep, which prevents it from reaching the deep sleep phase. A glass of wine at dinner is fine, but it is best to stop drinking alcohol three hours before going to bed .

Curtains

If you sleep in a room exposed to outside light, consider installing blackout curtains or blinds . Also turn off all lights on standby as well as screens that emit blue light (smartphone, television, tablet). According to a study cited by Reader’s Digest , when we are in total darkness, the body produces the hormone melatonin which helps us sleep better and burn calories.

Temperature

The body works harder to maintain a high body temperature, and thus burns energy, when the bedroom is cool . Lowering the thermostat by a degree or two can help you burn up to 100 extra calories in 24 hours of sleep. Another tip: sleep naked . This technique also makes it possible to decrease the temperature of the body, and therefore to make it work during the night.

Rest time

A new series or a very addicting book keeping you from getting seven to eight hours of sleep a night? Think about the benefits of a long enough night’s sleep. The energy expenditure at rest of people who sleep a whole night is 5% higher than that of people who do not get enough sleep . Research has shown that lack of sleep makes fat cells less sensitive to insulin . And this metabolic change is linked to obesity .
