SAD? No, it’s not the synonym of unhappy; it actually stands for Seasonal Affective Disorder.
If your smile disappears when the sun does, chances are, you might have SAD. Cadence Physical Therapy Co. say the sun’s light cheers up a person because of biochemical mechanisms. The body’s biorhythm is highly dependent on the sun’s light, basing its own clock on the sun’s schedule. During winter and prolonged deprivation of sunlight, the body’s body clock bogs down and depression can set in.
SAD therapy light reverses this phenomenon by giving off light just like the sun’s own. You can set it up in your office or at home in your room. You can use the SAD light therapy box even as you do your chores. The light emitted by SAD light therapy changes the biochemical reactions of the brain, helping people with seasonal depression.
Also known as bright light therapy, SAD therapy light is one of the many types of phototherapy that deals specifically with mood disorders related to seasonal changes. It gives off natural or white sunlight that modulates both melatonin and serotonin secretion, in turn modifying a person’s mood.
This is especially useful for SAD patients who work in rooms with very few windows or in areas with minimal sunlight. Most SAD therapy light boxes are portable so you can carry them to work and then back home every day. If you think you have Seasonal Affective Disorder, ask your physician about SAD therapy light and the many benefits it can give you.
