Overcast winter tend to make people's mood. Take a look at some of the following scenario: in the morning, got up to a lot of effort; for various social activities are not interested in many things simply twitch, before the hands do cold feet; feeling life, feelings of melancholy. If you have such a number in the winter, you may want to watch out, this means you may be seasonal mood disorder patients.
United States scientists discovered that the disease is due to the body's biological clock and the region was out of place. For example, in winter, early morning sunlight exposure is limited, the body's physiological cycle will be due to changes in solar capacity occurred slowly changing, growing and local places. This is why when I woke up early in the morning during the winter months, many people will feel not sleep very well. And worse, most of the time, we had to get up.
From a biochemical point of view, mankind's sleep and something called melatonin is closely related to the substance. In the back of the diencephalon, has an approximate size and shape of the flat tapered structure pea is called the pineal gland that secretes melatonin. Before going to bed at night in one of several hours, is melatonin large amounts of free time period, hormone let us gradually feel sleepy, bed. Some time later, melatonin secretion progressively reducing, to the morning, hormone secretion in the least amount. Melatonin secretion and human eye receives light also has a strong relationship, illumination, human melatonin inhibits the synthesis will be. When I sunshine less during the winter, the synthesis of melatonin is more and more, will affect people sleep and other physiological activities. Seriously, the body's biological clock and the local time from the physiological cycle is disrupted, it will become a seasonal mood disorder patients.
How to overcome the annoying symptoms, so that we can have good mood during the winter, not sleepy? eat antidepressant medication is certainly a way, but it's not a good idea. Since light reduction is the culprit, in turn, increase the light becomes mood disorders treated with seasonal recipe. Scientists found that adhere to the accepted 30 minutes every morning to 1 000 lux illumination of specific light (bright degree equivalent to a sunny summer daytime brightness) exposure, it will allow patients with mood on track so that it is wrong to physiological cycle gradually returned to normal.
However, because of different physiological cycle is different, choose the illumination treatment time will vary. If you are an early to bed, then in the morning, to accept the light therapy time in advance; but if you're a night owl type, clearly the best time of light therapy in respect of the subsequent push.
Light therapy is enables patients to look at the source, I just want people to feel the environment suitable brightness. Scientists even specifically designed to meet the requirements of the light box brightness, seasonal mood disorders in patients having breakfast or reading the morning paper, you can use this device for irradiation treatment, and sat on the Chair work, of course, is just as effective. In order to take full advantage of the time, a patient the light box installed in her treadmill next to the wall, so she is morning exercise, at the made of light therapy.
In the gloomy winter, we can be as energetic as the spring!
New patch: Lux
Illumination units, the illuminance is that the light intensity, the brightness of the light unit, it refers to the light (natural or artificial light source) to a plane of light flux density per square metre of surface by the amount of light. 1 Lux illuminance of the amount of light a candle is equivalent to the amount of light. In the same room, far from the light, the illumination of different locations are not the same.
