Seasonal Affective Disorder (SAD)
What is seasonal affective disorder?
Seasonal affective disorder (SAD) is a type of depression that comes and goes in a seasonal pattern. For most people it starts in autumn and is worst during the winter months, easing in spring.
The exact cause is not fully understood, but it is linked to reduced sunlight, which can affect the body's internal clock and the hormones that control mood and sleep. Construction workers who start and finish in the dark during winter, often in cold and wet conditions, may be particularly affected.

1. Mood:
- Persistent low mood.
- Loss of interest in everyday activities.

- Feeling stressed or anxious.
2. Energy and sleep:

- Sleeping for longer than normal and finding it hard to get up.
- Difficulty concentrating.
3. Appetite and social life:
- Craving carbohydrates and gaining weight.
- Becoming less sociable and wanting to stay in.
