A SAD lamp can help alleviate symptoms of seasonal affective disorder. These lamps are specially “designed to mimic sunlight” and when used correctly, can cause chemical changes in the brain, tricking it into thinking it's summer so it will release much-needed serotonin
Seasonal affective disorder (SAD) refers to a type of depression caused by changes in the seasons.
- People with SAD can suffer from depression, extreme tiredness, drowsiness, and changes to their appetite which can result in weight gain.
- SAD is more common in autumn and winter due to reduction of sunlight.
- This reduction may disrupt your body's internal clock and lead to SAD symptoms also known as winter depression.
- Studies point to a reduction in serotonin a neurotransmitter in the brain this may cause some of the symptoms associated with seasonal affective depression.
- The SAD daylight lamp uses LED to emit light diffusely reflects the light through the diffuser film and provides a brightness of up to 10000 LUX at a distance of 10cm from the lamp.
- It is thought that the light from such lamps may improve SAD by encouraging the brain to produce more seroton in while reducing the production of melatonin (a hormone that makes you sleepy)
