Darkness stimulates the production of the sleep hormone melatonin, so limiting screen time at night is helpful. But it’s also important to get plenty of natural light during the daytime - this is an essential part of regulating your body clock. Regular indoor lighting is no substitute; it is not bright enough to have the stimulating effect our bodies require in the morning.
Daily morning exposure to bright light is the most successful means of shifting one’s sleep schedule. While taking advantage of 30 minutes of sunlight exposure is an appealing idea, our work schedules, seasonal changes, and weather conditions do not always allow for this.
Bright light therapy is a substitute for the sun and a successful treatment to reset your circadian clock with regular use. It is also a healthy, drug-free alternative to solving sleep disorders. The HappyLight provides the necessary intensity of 10,000 lux light that is free of harmful UV rays.
