Light bulb temperatures helping SAD sufferers

As energy efficient light bulbs continue to help us save the planet day by day; choosing light fittings with specific colour temperatures can also help those who suffer from Seasonal Affective Disorder (SAD).

What is Seasonal Affective Disorder (SAD)?

SAD is a type of winter-based depression that affects around seven per cent of the UK severely and a further seventeen per cent mildly. It is caused by a chemical imbalance due to the shorter and darker days that the winter seasons bring. Symptoms of SAD can include depression, lethargy, weight gain and an increase in the amount of time spent sleeping. Some types of energy saving light bulbs and lamps can help to alleviate those symptoms.

How do specific lamps help?

By choosing a light bulb that burns high up the colour scale; six thousand kelvins or over (kelvins are the unit in which colour is measured), the light fittings will burn similar to the colours of summer and spring daylight. The illusion will help ease the symptoms for sufferers during the darker months.

BLT Direct offer fluorescent tubes, energy saving light bulbs and even halogen light bulbs in a range of colours. Steven Ellwood, spokesperson for BLT Direct says The most effective light fitting for SAD sufferers would be the fluorescent tube lighting we offer clients; as these types of fittings light larger rooms such as kitchens and garages, which wont often be lit by other sources or have smaller windows
