Seasonal Affective Disorder: Winter brings many symptoms, including sadness, laziness, and guilt, which we often ignore. However, this is a sign of depression, which is more common in winter.
The changing temperatures during the winter season can also affect our mood and mental health. The cold can sow the seeds of depression within us, which is called Seasonal Affective Disorder (SAD). This is a mood disorder that comes and goes with the seasons. It becomes more severe in the cold. So let's learn more about it in detail and what its symptoms are.
What is Seasonal Affective Disorder?
Seasonal affective disorder (SAD) is a type of depression, often called winter depression. Its symptoms are more pronounced in the winter because sunlight is less available during this time, which affects many brain functions.
Common symptoms of SAD
- feeling constantly sad
- Decreased interest in everyday activities
- increased irritability
- Feeling hopeless, guilty, and worthless
- Excessive daytime fatigue and sleepiness
- Difficulty waking up in the morning and sleeping more than usual
- Carbohydrate cravings and weight gain
- Difficulty concentrating
- Decreased sex drive
Many of these symptoms can be severe enough to affect a person's day-to-day functioning.
When to see a doctor
If you think you're struggling with SAD and can't manage it, consult a doctor or mental health specialist immediately. Your doctor will analyze your mood, lifestyle, eating habits, sleep habits, and changes in your behavior with the weather.
Causes of SAD
According to the NHS, the exact cause isn't entirely clear, but it may be due to reduced sunlight. Low light affects melatonin (the sleep hormone), serotonin (the hormone that regulates mood, appetite, and sleep), and the body clock. In some cases, SAD may be genetic.
Prevention and treatment of SAD
- Make lifestyle changes
- Spend as much time as possible in natural sunlight
- Exercise regularly
- Try to reduce stress
Light therapy is also offered. Individuals with SAD are exposed to artificial sunlight using a light box. Counseling is also provided.
