What is Seasonal Affective Disorder and Tanning Salons????

With the onset of the cold season, with the exception of cold snacks, some people have problems with general condition, lack of energy and depression of unknown origin. It was scientifically proven that lack of light stimulates the production of melatonin by the pineal gland, a hormone that causes sleep. That is why, in cold weather when days are short and sunlight is scarce, we often feel drowsy or drowsy. And, even in spring and summer, if the trend is to spend more time at home or in the office, the result may be the same, though less severe. Well, if drowsiness were the only effect of seasonal changes, things would be easier to deal with (with a little coffee perhaps!). The problem is that melatonin production is linked to the production of a neurotransmitter, serotonin, which is involved in a number of physiological processes such as temperature, blood pressure control, and neuropsychological functions such as appetite, memory, and mood. The two do not work together at the same time. When melatonin is produced, serotonin production is inhibited. Lack of serotonin causes disorders such as chronic fatigue syndrome and shows its effects on the air, causing depression in some people. Melatonin is active at night and serotonin is active during the day. Also, there is an age factor that contributes to the balance of two chemicals: melatonin production decreases with age. It has been found that the interaction between serotonin and melatonin and their dependence on body clock may explain the stress experienced by people with Seasonal Affective Disorder - SAD. Depression, sleep problems, obesity, anxiety, joint pain, irritability, depression, headaches are some of the symptoms that can occur when we suffer from SAD. The problem is mainly due to the lack of sunlight. Scientifically proven that sunlight tends to increase serotonin levels and favors the collection of vitamin D. In addition to being anti-osteoporotic, immunomodulatory, anticarcinogenic, antipsoriatic, antioxidant, vitamin D is also a modulator-modulator. . Exposure to UV rays promotes the formation of vitamin D on the skin. That is why people who go to the salon have noticed an improvement in mood and maintain a habit to maintain a sense of well-being. It is well-known, however, that the effects of UV exposure are not always the most desirable. If going to the salon becomes a habit, then the frequent, prolonged exposure to UV can cause effects such as premature aging of the skin and eventually skin cancer. Light therapy represents the treatment of SAD. Light acts on the body in two ways: by touching the skin or by entering your eyes. Only UV light that affects the skin, while the resulting light by getting into your eyes does not need to be UV, it should shine. Its energizing effect stems from the fact that it stimulates the production of serotonin. An easy way to get enough light to spend an hour a day or more outside, when light levels range from 1,000 to 50,000 lux or more, compared to room light, which can be 50-200 lux. If your plan or weather does not allow it, another option is to buy a simple medical device. For best results, the light source should be very bright - 5,000 lux or more - or it should be at a certain spectrum - about 460 nanometers, which is a blue width. According to a new study, blue light will provide benefits even at dark levels. Many companies that produce light bulbs make full spectrum lights that can effectively replace sunlight. However, there are side effects that may be caused by light activity, which may interfere with sleep (especially when exposure is done in the evenings) or cause some people to have mania - a condition called bipolar disorder (also known as depression). The safest is always outdoor natural light, provided that UV protection is used.
