The natural way to beat the winter blues or simply feel alert, energised and more positive
A large part of our basic behaviour and biology follows a 24-hour cycle. The sleep/wake cycle is the most obvious one but others such as body temperature, hormone production, cognitive performance and mood are all known to rise and fall during the day. These circadian (daily) rhythms are regulated by the body's internal clock and exposure to sunlight keeps it synchronised to a 24-hour day.
Melatonin is a hormone produced by the body that is important for maintaining a regular sleep cycle. When it's sunny or there's a lot of artificial light, melatonin production is low. As light starts to fade, production goes up. Melatonin levels are a way of telling our body what time of day it is so that it can react accordingly.
Serotonin is another important chemical linked to sunlight. People with depression and anxiety often have only low levels of this hormone, and increasing exposure to sunlight – or using light therapy – is a natural way of raising serotonin levels.
Light therapy is a safe, natural and simple way to improve health and wellbeing and, by helping to keep your body clock on track, light therapy also helps to provide an effective solution to sleep problems and other circadian rhythm issues. Light therapy can be used to help:
