Day 19:


For today’s rest challenge, use no light emitting electronic devices at least 1 hour before bedtime. Why? Historically, as sun light reduces in the evening  our brains have become hardwired to take this reduction of light as a cue to wind down for rest and sleep. In today’s society however, where electronic devices are everywhere and often used in the evening and at night, our brains are getting exposed to bright light and thus receiving the input to stay alert. Doctors and scientists have long known that light is directly related to sleep patterns and that disrupted sleep can lead to health problems. But electronic devices may be creating modern-day sleep problems – blue wavelength light from LED-based devices (phones, tablets, computers) increases the release of cortisol in the brain, which makes us more alert, and inhibits the production of melatonin which is needed to fall asleep. to  Give this rest challenge a go for a night and see how you get on, we’ll be back to the exercise-based advent challenges tomorrow!
