SAD Lights Difference From Ordinary Lights
SAD Lights are also known as SAD lamp, bright lights or sunlight lights. This is not an ordinary light which uses incandescent light like our study lamps or ceiling lamps. It mimics the UV Rays provided by the actual sunlight. Normally, it is always advised to have prescription of a doctor before using it. Incorrect purchase and use of this kind of light may cause skin burn or eye ailments which are both easy to correct given that it will be attended with proper care immediately.
Mainstream seasonal affective disorder light typically emits 2,500 up to 10,000 lux or light intensity or lumen per square meter. Using full spectrum bulbs, this type of special light emits UV rays just like what people naturally receive from the sun aside from the light provided by both.
The sun actually emits 100,000 up to 350,000 lux, far enough from what is being emitted by the regular light which is only 300 up to 500 lux. Generous amount of lumens that produces UV rays promotes the reduction of melatonin and production of human serotonin. This type of light is manufactured intentionally to cure seasonal affective disorder or SAD.

SAD Lights – The Best Alternative Treatment For SAD
Seasonal Affective Disorder or SAD has been formally explained and identified by Norman E. Rosenthal and his colleagues at National Institute of Normal Health during 1984. This particular mood disorder is curable and is often referred to as winter depression, summer depression, winter blues or summer blues. As a result, circadian rhythm or body clock distraction is experienced. It is popularly known as seasonal depression because people living at places where the sun becomes scarce during winter and falls are the ones who usually experience SAD.
To counter act unwanted effects of lack of sun exposure, it should be treated immediately. If SAD is permitted or uncontrolled, bipolar disorder or depressive disorder is at stake during these seasons as dictated by its symptoms. Among treatments to SAD are SAD Lights, use of fluoxetine, sertraline, or paroxetine as antidepressant medication or melatonin hormone supplement.
Now, understanding SAD is important to easily identify and correct the reason of sudden mood disorder, which affects normal life routine. SAD generally is caused by sudden increase of melatonin due to lack of UV rays usually received from the sun. Melatonin is important to human body because it is actually the hormone which makes people sleep at night. As a result to increased melatonin, the tendency is to feel distressed and restless. Also, human serotonin is reduced which is why people who suffers from SAD experience chronic sadness or severe depression. Serotonin is actually a neurotransmitter that affects mood, the exact reason why mood disorder is experienced due to its serotonin deficiency.
Bright lights can be used to cure seasonal affected disorder which replenishes lack of sun exposure by emitting UV rays caused by 10,000 lux on its spectrum bulbs. If ample amount of UV Ray is absorbed by the body, seasonal affective disorder symptoms such as social withdrawal, decreased sex life and loss of energy could be avoided. Therefore, higher chances to suffer bipolar disorder and depressive disorder could be eliminated clearly.
Accurate distance to prescribed lux or lumens should be observed during SAD therapy using bright lights. Too much UV rays received from bright lights may lead to hyper activity, another disorder you do not want to substitute with SAD. AT any rate, it is important to stay in front of the light on a prescribed time every morning usually within seven to ten days. Skipping a day of SAD light therapy would mean no effect to the entire treatment, so make certain on the prescribed time span to UV Ray exposure.Check out Verilux HappyLite Deluxe SAD light.
