While many people see daylight savings times as an opportunity to save an hour of sleep on that special Saturday night each fall, it can also bring on a variety of health-related issues for many people. For those of us living in the northern latitudes, it means significantly shorter days and much less light exposure. The reduction in light exposure and shorter days can affect the regulation of our normal sleep – wake cycle, in addition to bringing about changes in our own circadian rhythms. This can affect the production of several hormones in our body such as serotonin and melatonin. And less of these hormones can significantly impact our daily productivity as well as our normal sleep cycle. The ultimate result of these hormonal imbalances include sleep disorders, depression, fatigue and also seasonal affective of disorder.
