Seasonal insomnia may be driven by vitamin D deficiency

Vitamin D for Better Sleep?

Seasonal insomnia typically strikes at about this time of year. As the days get shorter, we’re exposed to shorter periods of sunlight, which can alter circadian rhythms and interfere with sleep.

A related problem has to do with our need for vitamin D, which may not be met in low sunlight conditions. Recent publications explore the effects of low levels of vitamin D on sleep, making supplements a good option in the cold weather.
