What is seasonal affective disorder (SAD)?
Seasonal affective disorder (SAD) is a type of depression that occurs during certain seasons, usually in late autumn and winter. It causes symptoms such as gloominess, fatigue, cravings for food (especially sweet foods high in carbohydrates) and a decrease in interest in daily activities.
The difference with other types of depression is that the symptoms disappear again in the spring. For example, approximately 3 in 100 people in the United Kingdom suffer from winter depression.
The sun and vitamin D: a warm connection
Our bodies produce vitamin D when we are in the sun, mainly through UVB rays. These sun rays help our skin to produce vitamin D, which is important for various processes in our bodies. In winter, when there is often less sunshine, our bodies cannot produce enough vitamin D.
Vitamin D and our mood: what does science say?
Scientists have investigated how vitamin D can affect our mood. Research has shown that people with low vitamin D levels are more likely to experience feelings of depression.
This suggests that vitamin D plays a role in our emotional health, especially in SAD.
How vitamin D deficiency makes us feel down
Vitamin D affects our mood through the action of chemicals in the brain, such as serotonin. A vitamin D deficiency can disrupt these chemicals, which can lead to feelings of gloom. This deficiency is common, even outside the winter months.
Unfortunately, vitamin D deficiency is common in many people, and not just in winter.
Vitamin D supplements and light therapy: a sunny solution
How can we tackle this problem? The easiest option is to take vitamin D supplements to replenish our levels. Especially since the sun is hard to find in our little country during the winter.
Light therapy is another option, where you expose yourself to bright artificial light to mimic the effects of sunlight.
Lifestyle tips for a sunnier feeling
In addition to supplements and light therapy, there are also things you can adjust in your lifestyle. Regular exercise, eating foods rich in vitamin D and spending as much time as possible outside in natural light can all contribute to a sunnier mood.
