What is seasonal affective disorder & how to know if you have it
Seasonal affective disorder is a lot more than missing lighter and brighter days. Also known as SAD, seasonal affective disorder is a type of depression that is triggered by reduced exposure to sunlight during the darker autumn and winter months.
From finding it difficult to wake up in the morning and experiencing daytime fatigue, through to craving carbs and generally experiencing a low mood, SAD can cause a variety of symptoms.
It is estimated that one in three people in the UK suffers from seasonal depression disorder and the most common period for an onset of SAD is between September and December. You might even hear many people refer to it as winter depression.
We’ve created a helpful guide covering what seasonal affective disorder is and how to know if you have it.
What is seasonal affective disorder?
The vast majority of us have heard the term SAD before, but do you know what it means?
SAD is a term used to describe the theory that a lack of Vitamin D and sunlight can affect the part of the brain known as the hypothalamus from working properly. When this happens, it can affect the production of melatonin, a natural hormone that helps control the sleep cycle. People who experience SAD are also known to produce higher than normal levels
of serotonin, the hormone that helps to stabilise our mood, wellbeing and happiness, as well as helping with sleeping, eating and digestion.
It is also thought that SAD may be hereditary and run in families.

Common treatment options for SAD include:
