Does light impact my hormones?

Yes! Exposure to light impacts two hormones in particular: melatonin (sleep promoting hormone) and cortisol (stress hormone). If the light is too bright (greater lux), then less melatonin is produced (leading to feeling awake not sleepy) and more cortisol is released (leading for feeling more stress). Too much light at the wrong time will WIRE YOU UP not WIND YOU DOWN.

Practical Application: Remember, darkness is your friend if you wish to fall asleep and stay asleep. If you wish to feel alert and energized, go to the light…outdoor light is far better than indoor light because outdoor light can yield 150,000 lux compared to indoor light levels of maybe 500 lux.
