Before sleep, however, these alerting effects need to be minimized, otherwise it will be harder to fall asleep and the quality and depth can be compromised. Exposure to blue-depleted and dimmer light is therefore recommended for as long as possible before sleep. (See our GoodNight and SleepyBaby products)
Sleep is vital for good health. In the short-term, poor sleep leads to sleepiness, fatigue and poor performance, which can impact safety and performance at work or while driving. The American Academy of Sleep Medicine recommends a minimum of 7 hours per night in adults, although often people need more to maintain optimal performance. Sleep should be prioritized each and every night, as it’s very hard to ‘catch-up’ on sleep, even on weekends.
Longer-term, sleep deficiency has been linked to an increased risk of high blood pressure, heart disease, stroke, diabetes and some types of cancer. There is also a strong relationship between poor sleep and mental health, including the risk of depression. These risks are exacerbated in individuals who routinely sleep poorly, for example in shift workers; and the World Health Organization has designated shiftwork that causes circadian desynchrony a ‘probable carcinogen’. Sleep should be considered one of three pillars of good health, along with diet and exercise, and should be prioritized as part of a healthy lifestyle.
