THE Mental Health Foundation this week issues a reminder that the clocks go back on Sunday.

Every year, many thousands of people dread the onset of winter, not knowing they are actually dreading Seasonal Affective Disorder (SAD).

SAD is a winter depression affecting about half a million people.

It can be totally disabling but it can also be treatable.

Symptoms include lethargy, sleep problems, depression, anxiety, social problems, loss of libido and overeating.

SAD can begin at any age but it most commonly starts between 18 and 30.

Winter can be a very difficult time of year for people affected by SAD.

The shortening of the daylight can have dramatic effects, yet many people do not realise SAD is treatable.

Our advice is, don't suffer in silence.

Book an appointment with your GP to talk about your symptoms and identify ways they can be treated.

Light therapy has proved to be effective in up to 85 per cent of diagnosed cases.

This simply involves sitting in front of a special "light box" allowing the light to reach your eyes.

SAD may also be treated with anti-depressants.

The Mental Health Foundation's tips for SAD sufferers include:

Making the most of the light that is available by getting out of doors.

Decorating your home in light colours.

Staying near the windows at home and at work.

Considering taking a holiday somewhere bright and sunny (although a small number of SAD sufferers have felt worse returning to the UK from very bright sunshine).

Accepting that you do not cope as well in winter and planning your life accordingly - leave major projects until the spring, and concentrate on staying well during winter.
