As the seasons change each year, some people are particularly sensitive to the variations in sunlight patterns that occur as days become shorter and nights become longer. The most difficult months are typically January and February, though some people find the transition into summer months to be just as trying.
Sun exposure and the length of daylight influence the body's production of certain hormones, chemicals, and neurotransmitters, as well as its production of vitamin D. All this can affect mood, energy level, metabolism, and sleep/wake cycles (or circadian rhythm). Light is a vital component in the body's natural ongoing healthy-maintenance process.*
Studies have show that light therapy can promote a healthy circadian rhythm in as little as a week. Light therapy is a very gentle method for resetting the body's circadian rhythms and re-establishing natural patterns of hormone production and sleep/wake cycles. This, in turn, supports healthy energy levels and overall balanced mood.*
In combination with good nutrition and regular exercise, adding high-quality nutritional supplements are also helpful.*
