Lose weight while you sleep with these 7 tips

USE OF DIGITAL DEVICES

Our smartphones and tablets emit blue light, which is known to sharpen attention and reaction time and increase wakefulness. While these benefits are undoubtedly beneficial during daytime hours, they are counterproductive when trying to drift off to sleep. And if your sleep suffers, you are less likely to lose weight, as per the above point. Try allocating 30 minutes to an hour of screen-free time before lights out. If you use your device before bed, install a free app that blocks blue light emissions.
