People exposed to more artificial light at night are more likely to:

See double

Sleep fewer hours

Have better brain function

Lose weight

Studies show that people exposed to more artificial light are likely to sleep fewer hours. This is because artificial lights have blue light waves, just like daylight. This can reduce levels of the hormone melatonin, which signals to our brains that it’s time to go to sleep. Read more here about artificial light and how it can affect your sleep.
