Each morning: let there be light
A robust circadian rhythm starts with bright light in the morning:
A walk outside (or just sitting) for 15min+
with no sunglasses!
or
A full-spectrum very bright indoor light
*no medical advice is given on this page, ask your doctor if sitting outside for 15min is ok for you :)
You are not getting enough light/energy during the day
It may not appear to be much brighter outside…
86 lux = Daytime lighting indoors
(with 14 overhead LED flood lights)
…however, even on an overcast day it’s ~13x brighter outside than it is inside with all lights on.
When there’s no clouds, it’s up to 1,000 times brighter outside than indoors.
1080 lux = outside full cloud cover at 8am
If you can’t get outside, have a good bright indoor light to use
Here’s a couple that we tested…
“SolShine Photo Nutrition”
This is basically 18 bulbs in one (hence the $133 price tag w/ 10% discount)
Half of the lights in this bulb are non-visible infrared; infrared is important because…
“LED light exposure that is not balanced with full (spectrum) sunlight loaded with the red parts of the spectrum is always damaging to your biology.”
— Dr. Alexander Wunsch MD, PhD, Photobiology Expert
11,200 lux at 2ft distance
This thing’s bright!
Notice only half of the 18 LEDs are visible
(iPhone camera picks up a little infrared from the others)
Average R1-R15 CRI of 95
This is the color rendering index
Numerically, the highest possible CIE Ra value is 100 and would only be given to a source whose spectrum is identical to the spectrum of daylight
Just some of our favorite studies on this subject
(there’s 10,000+ studies on circadian rhythm out there, these are just the tip of the iceberg)
“Our findings… found that changes in the timing of light exposure were associated with body weight, independent of caloric intake” - Reid, 2014
