In North America, it is estimated that 50 to 60 percent of the population is affected by winter depression. There is a broad spectrum of symptoms that arise, from a change in sleep patterns and weight gain, to overwhelming suicidal thoughts and the unfortunate results. This means about half of the people you know are depressed in the wintertime!
Wintertime depression is most common north and south of the equator. People who live near the equator have a very low incidence of winter depression. The reason for this is they live where there are enough daylight hours to avoid triggering the hormone imbalance that causes depression. What matters is the length of the day (daylight hours), not the weather. Depression in the winter is called Seasonal Affective Disorder.
People who live in northern climates suffer because of the seasonally shortened days. Just as trees lose their leaves when the days shorten, people lose their happiness. People who live where the days shorten seasonally are victims of the brain’s chemical reaction to lesser hours of daylight.
