Let the Light in

Light exposure, being the most influential factor in aligning our body's internal clock, not only impacts a restful night’s sleep but can affect mood and hormone production.

In a simpler time, before artificial light was invented, human’s circadian rhythms naturally followed the daily sun cycle. In modern times, artificial lights and electronic devices are an inevitable part of our daily lives.

This “blue light” is the type of light that most alters our sleep cycles. Blue light exposure can negatively impact sleep if used too close to bedtime but can also be used to influence a healthy sleep cycle if used during normal waking hours.

The good news is that being mindful of daily light exposure type, duration and timing can positively affect restfulness. Daily morning sun exposure not only improves general mood but also aids in getting a better night’s sleep.

If you decide to give morning light exposure a try, be sure to leave the sunglasses behind and try to do this shortly after your alarm goes off. For the best results, aim for 20-30 minutes when possible, but even five minutes can trigger a healthier night’s rest. On a cloudy day, shoot for an additional 10-15 minutes.

To wind down for the evening, make sure to put those devices away at least two hours before bedtime and focus on yellow, amber or even candlelight to prepare the body for rest.
