Do SAD lamps work? It's that time of year again and as the nights draw in and the mornings get harder to face, it's a question that you won't be alone in asking.
SAD stands for Seasonal Affective Disorder and is a condition defined by the NHS as a 'type of depression that comes and goes in a seasonal pattern'. The condition is also sometimes known as winter depression, as it strikes as the colder weather and lack of warmth and sunlight begin to have an adverse effect on a person's feeling of happiness.
