The winter solstice is fast approaching in the northern hemisphere, and the days are becoming shorter and colder. It is quite normal to be feeling the winter blues at this time of year, but some people experience a more extreme and seasonal form of depression that interferes with things like their mood and sleep. This condition is known as seasonal affective disorder (SAD) and is believed to be caused by a decrease in light exposure during the winter months.
The body’s circadian rhythm depends immensely on sunlight, and when it’s not in abundance during the winter months, disruptions to the biological clock can be experienced. With lower vitamin D absorption, and lower serotonin and melatonin production, the following can be experienced:
- Low energy and mood
- Difficulty concentrating
- Changes in weight and appetite
- Disrupted sleeping patterns
During the winter months, we recommend to get as much sun as possible, stay active and ensure you don’t sleep for more than 7-9 hours a night.
