Melatonin production increases as light intensity falls and it is responsible for inducing sleep. Clearly Melatonin, as the sleep inducing, hormone, slows us down making us less alert and depresses our mood. Anybody who wakes up at 4 o'clock am will testify that thisis not the happiest time to wake up. Melatonin production is stimulated by low exposure to sunlight.
Sunlight has the reverse effect, it suppresses the production of Melatonin which is produced from the feel good hormone, Serotonin. Thus, exposure to Sunlight results in increased Serotonin levels and reduced Melotonin levels. We all know how much better we feel when the sun is shining.The problem for those of us living in Northern latitudes, is that we go to work in dark, grey, drizzly weather, sit in the office all day, well away from the sunlight and then return home at night. Little wonder then, that many of us suffer from the winter blues or seasonal affective disorder (SAD).
