Could too much light at night give you depression?

BEING exposed to even dim light at night can increase the risk of depression by almost 90 per cent, say scientists.

Japanese researchers recruited 900 people who had no signs of depression and fixed light meters in their bedrooms to gauge their exposure over two nights. They then studied their mental health over two years. Those exposed to light were 89 per cent more likely to develop depression than those in total darkness, according to results in the American Journal of Epidemiology.

It’s thought light penetrates the eye and disrupts our built-in clock, which may affect mental health.
