What is Seasonal Affective Disorder (SAD)?
SAD is a type of depression that occurs during autumn and winter, and disappears in the spring and summer months. Symptoms will appear around the same time every year.
SAD often affects those who live further away from the equator. Due to this, it is believed that the shorter days and the reduced levels of sunlight in winter can trigger it.
Many of the symptoms can be overlooked or ignored as feeling a bit down in the dumps, but it is important to speak to a doctor if you are experiencing seasonal depression every year.
The exact causes of SAD are not well understood. As we briefly mentioned above, it is believed that the lower levels of sunlight during the darker months disrupts some people’s biological clock. This can result in the body producing less serotonin and more melatonin.
Serotonin is a chemical in the brain that affects people’s mood. Low levels of serotonin could be one of the reasons why people experience SAD.
Melatonin is created in the body when it is dark and is responsible for helping us sleep. When it gets light, the body stops producing it, but it has been found that people with SAD may have increased levels of it in their body. This can change their sleeping patterns and make it harder for them to get up in the morning.
The symptoms of SAD often begin to appear in young adults, but they can affect people of all ages. It is also more common in females, but again, it can affect anyone.
SAD affects people in different ways. The symptoms are similar to depression symptoms. It occurs around the same time every year, usually in the winter.
