How to sleep?
In order to reduce the total amount of time you spend sleeping, you must increase the quality of your sleep first. Both light exposure and your activity levels affect your body temperature rhythm in a very big way. high intensity light has a huge effect on the strength of your sleeping system.
If you expose yourself to light during the day, your body temperature rhythm will “peak” at a higher point and will fall at a later point. You’ll experience better sleep and will be able to lower your amount of sleep. If you get inadequate light exposure your body temperature will be closer to “flat-lining”, preventing quality sleep and lowering your energy levels throughout the day. Lack of sunlight also inhibits melatonin hormone secretion, this further promotes lower energy levels and sleep difficulties.
