Turn your phone, TV and lights off before bed and sleep with a mask, scientists say Northwestern researchers have found a link between light exposure and obesity Study shows 40.7% of people exposed to light before sleep were obese  Only 26.7% of group not exposed to light for five hours were obese

Turn your phone, TV and lights off before you go to bed if you want to stay slim.

For scientists have, once again, uncovered a link between exposure to light during sleep and obesity.

The latest evidence, purely observational, does not prove being that bright flashes while your eyes are shut make you fat. But proof that light at night fuels weight gain is rapidly piling up. 

Academics recommend people wear masks at nights and fix blackout shades onto their windows, as well as turning off their devices. 

And people who need a light on — such as the elderly — should only use a dim one close to the floor.

HOW DOES LIGHT AFFECT SLEEP AND WHAT CAN YOU DO?

Circadian rhythms are around 24-hours in length.

They vary from person to person - which is why some people are 'morning people' and others are 'night owls'.

Natural factors within the body produce circadian rhythms as well as environmental signals such as daylight.

Irregular rhythms have been linked to various chronic health conditions, such as sleep disorders, obesity, diabetes and depression. 

Exposure to light suppresses the secretion of melatonin, a hormone that influences circadian rhythms and helps with sleep.

Melatonin levels rise in the evening and stay elevated throughout the night, promoting sleep. 

Artificial lighting and electronics with blue wavelengths trick the mind into thinking it's daytime.  

How can you reduce your exposure?
