The rolling out of bed in the morning if you have problems, and to feel abnormal all the weary gloom wintery day of the month, such as the 10 million other Americans, can suffer from seasonal affective disorder (SAD). For years, people have to be considered in the light of the winter blues "and artificial throughout the day, a new study has found that extra dose of light therapy, high-performance computing (HPC), the processing of a depression, as well as other types of heartbeat.
Persons with disabilities begins in the autumn, the SAD feeling, which lasts for the entire month of spring-into-and sometimes even in the winter because of the shorter days, do not provide enough in direct sunlight feel. Bright light treatment (BLT), also known as the daily therapy, phototherapy, is composed of at least 30 minutes, by examining, indirectly, the "light box", which contains a specific kind of bright light. Points of light wavelengths of sunlight to simulate a brighter than on a regular basis and have the lamps they beam off the light intensity measuring at least 10 000 lux. (Sunlight, in fact varies from 32 000 100000 Lux, the average day.)
Shown previously in force at the time of the BLT substances related to the SAD depression symptoms are such as unforeseeable and encouraging people to increase the production of fatigue, such as serotonin and Dopamine, which contribute to the positive emotions. This helps the SAD symptoms such as Irritability, anxiety, drowsiness, and in order to mitigate the effects.
Recently, Ritsaert Lieverse, Amsterdam inGeest, psychiatric institution GGZ decided to test the researcher are suffering from depression BLT people (MDD, also known as clinical depression), a form of depression that are known to throw off the circadian rhythms SAD in the same way. The condition is particularly important for the elderly, many get enough exposure to the sunlight.
Lieverse's team delivered 42 patients at least, not all MDD 60-year-old, bright blue light used in the home one hour every morning, three weeks; another 47 patients received dim red light shall be a placebo. A study published in the journal Archives of General Psychiatry January 3, reported that 58% of the patients with reported actual BLT blue light depressive symptoms, even less, only 34% of the placebo group had.
BLT's benefits may be due in part to how the body returns to its circadian rhythm extra exposure to bright light, more space on the screen. Lieverse Researchers observed a greater increase among the compared to those who used a placebo bright light therapy, hormone Melatonin night.
Simply by using the BLT with more and higher-watt bulbs in the lights can be literally the Add brightness depressed person's life.
"If the BLT to reduce seasonal depression in elderly patients, then easily add the lighting can be restricted to antidepressants for the treatment of patients and to serve as a separate add-on or incontinence in elderly depressed patients in homes," the study concluded.
