I've written before about the link between light and insomnia.
I even pointed an accusatory finger at Thomas Edison.
Now, a new study has discovered that exposure to indoor light has a strong suppressive effect on the hormone melatonin. This can consequently affect the quality of our sleep as well as the body's ability to regulate temperature, blood pressure and glucose levels.
Their advice is simple - turn down indoor lighting at night and keep your room dark when trying to sleep.
Perhaps it's time to invest in a dimmer switch... or get rid of those pesky lightbulbs altogether.
