The NHS has urged the public to be aware of the symptoms of Seasonal Affective Disorder (SAD), a condition that can become more severe during the winter months. In a post on social media platform X, the health service highlighted that symptoms of SAD are often more apparent and severe in winter, and encouraged people to know the signs and available treatment options.
SAD, sometimes referred to as 'winter depression', is a type of depression that follows a seasonal pattern. The NHS explains that while symptoms typically worsen in winter, some individuals may experience them during summer and feel better in winter. For some, symptoms can be severe and significantly impact daily activities.
Common signs include lethargy and sleepiness during the day. The exact cause is not fully understood, but reduced sunlight exposure in autumn and winter is believed to affect the hypothalamus, potentially disrupting the production of melatonin and serotonin, and altering the body's internal clock. Genetics may also play a role, as SAD can run in families.
The NHS advises those struggling to cope with SAD symptoms to consult their GP. A doctor can conduct a mental health assessment, asking about mood, lifestyle, eating habits, sleep patterns, and seasonal changes in thoughts and behaviour.
