As the days get shorter and darker in autumn and winter, some people experience changes in mood and energy known as Seasonal Affective Disorder (SAD). It’s a type of depression linked to seasonal changes.
❓ Common Symptoms
- Low mood or feeling sad most of the day
- Loss of interest in usual activities
Tiredness, low energy, or difficulty concentrating
Sleeping more than usual
Changes in appetite, particularly craving carbohydrates
Causes of SAD


While the exact cause isn’t fully understood, factors may include:
- Reduced sunlight exposure: This can affect the body’s internal clock (circadian rhythm).
- Lower serotonin levels: Sunlight helps regulate serotonin, a brain chemical linked to mood.
- Increased melatonin production: Darkness can cause the body to produce more melatonin, leading to sleepiness and low energy.
Tips for Managing SAD
- Maximise daylight: Spend time outdoors during daylight hours.
- Stay active: Physical activity helps boost mood and energy.
- Connect with others: Social support can ease feelings of isolation.
- Healthy habits: Maintain regular sleep, a balanced diet, and routine.
- Light therapy: Special lamps may help some people.
- Seek support: Talk to your GP if symptoms are severe or ongoing.
