The surprising secret to a good night’s sleep
Do you struggle to get a full night’s sleep? Do you often lurch awake in the middle of the night?
Well, you may be interested in the latest surprising sleep advice.
Apparently, the secret to a blissful eight hours could be as simple as brushing your teeth – in the dark!
According to Oxford neuroscientist Russell Foster, humans have evolved to respond to natural light levels, telling us whether to wake up or wind down.
But the artificial bathroom light interrupts the process, inhibiting sleep-promoting neurons in our brains, while activating neurons that boost alertness.
So basically, bright bathroom lights wake up our bodies at a time when we’re supposed to be preparing to rest.
Speaking to the Daily Telegraph, Professor Foster pointed out the inconsistency in many peoples’ night-time routines: “Often people will turn their lights down at night which helps to get the body ready for sleep, but then they will go and brush their teeth and turn their bathroom light on.
“That is very disrupting. I often think someone should invent a bathroom mirror light which has a different setting for night-time.”
Alternatively, you could always go with the glow of the hall light.
Whether or not you agree with Professor Foster’s advice, you can’t ignore the fact that science says we need at least seven and a half hours a night to function at our best.
So, if brushing our teeth in the dark can help get us there, I say we flick the switch!
