Exposure to artificial light at night is linked to a higher risk of diabletes and heart attacks research suggests

Researchers in the US say they have found that people who are exposed to light at night time show worse glucose and cardiovascular regulation compared with those who slept in the dark

According to a study conducted by researchers from Northwestern University in Illinois it is crucial to minimise or avoid entirely, if possible, the amount of light exposure during sleep to avoid the risk of diabetes and heart attacks.

The Mail Online reports: An experiment on 20 adults revealed that it only took one night of ‘moderate light exposure’ for the body to experience the harmful effects. 

In light of their findings, the experts have urged people to reassess the illumination of their bedrooms.

Study author Dr Phyllis Zee said: ‘If you’re able to see things really well, it’s probably too light.’ 

She said people who do need some light – for example, an elderly person needing to ensure they don’t trip – should use a dim light close to the floor. 

Regularly getting a bad night’s sleep has been linked to a plethora of other medical problems, including obesity and depression.
