Brush Your Teeth in the Dark to Help Sleep, Says Oxford University Neuroscientist
Sleep has been negatively affected by the invention of the light bulb. A group of researchers claims exposure to bright light and working into the night have adversely affected sleep quantity and quality.
Key takeaways:
- Turning on the bathroom light to brush the teeth after having turned off all other lights in preparation for bedtime may affect the ability to fall asleep.
- Staying indoors during the day may knock off about 46 minutes from the amount of sleep you get at night. Indoor lighting provides 300 to 500 lux compared to 100,000 lux of a sunny day.
- Sleep is essential for repairing damaged tissues, clearing toxins, and restoring metabolic pathways.
Russell Foster, professor of circadian neuroscience, claims that the bright fluorescent light of bathrooms wakes the body up just when it should be switching off.
