Senior lecturer in clinical studies at Monash University Dr Craig Hassad, says it relates to a natural reduction in energy, which tends to occur in the winter months. “The lack of sunlight has a negative effect on mood, which in its more extreme form is a type of depression â€" Seasonal Affective Disorder (SAD).â€
SAD tends to strike at the start of winter, hence why people often refer to it as the ‘winter-blues’.
The exact cause is not known, but it’s often blamed on a lack of available sunlight.
One theory is that with decreased exposure to sunlight, the biological clock that regulates mood, sleep, and hormones is delayed, running more slowly in winter.
Dr. Hassad says although humans don't hibernate, there is a natural reduction in energy usage in winter. “That is probably an evolutionary remnant of when food was scarce at such a time.†He says this low feeling can be stamped out by staying active, getting some winter sunlight, maintaining a healthy lifestyle and pacing yourself throughout the year.
