At this stage, we’ve all heard the advice that you should put down your phone and other electronic devices late at night as the blue light can affect your slumber. But there’s a flip side that hasn’t been discussed as frequently.
Sleep psychologist Michael Breus says that red light can actually help you drift off to sleep more easily. He explains, “The theory is that red light aids melatonin production.” This is the hormone that makes you feel drowsier, the production of which is suppressed by blue light.
Thankfully, you don’t necessarily need to light up your room in red. Red spectrum bulbs minimise blue light wavelengths and maximise red ones without actually coming across as red. According to Breus, it’s the spectrum of the light that actually makes a difference rather than the physical colour.
