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.
Having a BMI above 30 — defined as obesity — puts people at greater risk of type 2 diabetes, heart disease, and cancer.Roughly a quarter of adults are obese in England but prevalence is closer to the 40 per cent mark in the US, figures suggest.Researchers at Northwestern University in Illinois tracked 552 people, aged 63 to 84, in their study, published in the journal SLEEP.Although the study only looked at older people, previous research has shown similar effects in younger generations.
