Day 4 is here, and today, we have one of the most important challenges!
This challenge is one that may have a significant effect on our health, but because of our modern day lives, it may not be something we think about as often as we should.
It’s about our exposure to light. Light, of course, is life! However, we aren’t supposed to be exposed to light for 24 hours a day.
That’s why, this evening, your challenge is to:
(ARTIFICIAL LIGHT AT NIGHT)
To do this, you can:
- Dim the lights in your home as much as you can once the sun goes down
- Use light bulbs with a red tint instead of a white tint
- Switch off electronic equipment and avoid looking at bright screens three hours before bed
- Use amber-tinted glasses if you need to use electronics or have a particular need to have bright lights on at night
Imagine a time where you would wake up when the sun came out and go to sleep when the sun went down. When you had no choice because there was no other source of light besides possibly candles or from a fire.
How times have changed! Now, all we do is flick a switch and we can have ‘daylight’ for as long as we need. It’s great for productivity, but not so good for our health.
Being exposed to light for extended hours in the day disrupts our natural sleep/wake cycle, which is called our circadian rhythm. Light tells our brains to stay awake, and when we suddenly turn the lights off and want to go to sleep, it takes a while for the brain to then comprehend the message. It’s for this reason that many of us lie awake at night, unable to sleep; our brain is just too ‘wired’ from the light signals.
It’s not only sleep that suffers. Research shows that consistent exposure to light at night, for long periods of time, may impact health, and it has been linked to the development of diabetes, heart disease, obesity and even cancer.
One of the reasons for this is the impact it has on the production of the hormone melatonin. Melatonin helps us to keep our circadian rhythm in check and, while light of any kind can suppress melatonin secretion, blue light, in particular, does so with greater effect.
To protect you health and improve your quality of sleep, take today to experiment with reduced light exposure. Take note of how you feel tomorrow morning. Take it one step further and schedule in another low-light evening at least once a week over the next couple of weeks.
To your good health,
