Circadian rhythm is the internal clock that regulates the body’s sleep and wake cycles over a 24-hour time period. Because circadian rhythm is controlled by the part of the brain that responds to light, alertness tends to peak during the day and decline at night. Sleepopolis maintains an affiliate relationship with some of the products reviewed, which means we get a percentage of a sale if you click over from our video (at no cost to our viewers). Also, many mattress and sleep product companies send us their products for free with the hope that we will like it and review it.
