how it works

As the days draw in during autumn and the general daytime light levels reduce we therefore process less light via our retinas. This causes us to produce higher levels of a hormone called melatonin. Melatonin is a hormone which we produce, via the pineal gland, during the evening and night and is secreted into our bloodstream so as to induce and maintain sleep.

However, people who suffer with seasonal affective disorder will process so little light that they thus produce high levels of melatonin. This causes the individual to feel very tired and lethargic, to the point that they could sleep at any time during the day. Other symptoms are lack of motivation, feeling unsociable and a low mood.

The low mood or depression is brought on for the following reason. As the SAD sufferer is producing high levels of melatonin, this melatonin is in turn using serotonin as a part of its production. Serotonin is a hormone or neurotransmitter which is produced in a structure of the brain called the amygdala, which is part of the limbic system or animal part of the brain and is largely specific for emotions like happiness and depression.

So, low light levels cause high melatonin production (fatigue etc) and as a consequence, low serotonin levels (depression, anxiety etc).

High light levels, as measured through a light box and over a set length of time, will quickly reverse these effects.

Our retinas pick up this light and change it into electrical pulses, which are sent directly to the pineal gland, and thus signals for the reduction of melatonin production. With the melatonin production reduced, serotonin levels will therefore increase. The ultimate outcome of light therapy is that the individual who is suffering with SAD will soon become much more energetic, motivated and more optimistic. Indeed, a lot like the SAD sufferer will normally feel during the spring and summer (back to his/her true self).
