A medical survey shows that the average life of about 300,000 golfers in Sweden is about five years longer than that of Swedish people who don't play golf. It is well known that proper exercise is good for health, but why can golf bring such a significant life difference? Professor Hiroda Kazuo from the Medical Department of the University of Tsuyoshi University pointed out that an important possible factor is "Violet Light".

The relationship between purple light and health

Purple light is a kind of solar light with a wavelength of about 360 to 400 nanometers, between ultraviolet light and blue light. It has been widely studied as a key light to prevent childhood myopia, or maybe you have heard of related discussions. However, the effect of purple light is far beyond close-mind prevention and control. In his book "Outdo Time Determines Your Health and Life", Professor Masayoshi Tsukida pointed out that Unigroup may have improved effects on a variety of diseases such as depression, Parkinson's disease, dementia, and sleep disorders. So, how exactly does Unigroup have a positive impact on health? The following will explore the practical application methods of Unigroup based on Professor Pingtian's research.

{9 The remaining five types are not responsible for vision, but adjust their physiological functions through light lines. Professor Masashi Tsukita explained the role of these receptors: "These receptors do not pass through vision, but directly use optical information to increase survival chances, such as maintaining health, adjusting body functions, adapting to the environment, relieving pressure, controlling sleep, and even affecting the consciousness of crisis and sense of security."

For example, one of the OPN4 photosensitive receptors is responsible for adjusting the night rhythm of the day (physiological clock) and is activated by blue light. Therefore, when using your phone at night, the blue light emitted by the screen will affect the brain and make people more awake. In addition, studies have found that by stimulating OPN4, mice's memory has also improved. As for other non-visual photoreceptors, most of them are also activated by blue light, with the only exception being OPN5, which only reacts to purple light. Its functions include adjusting the physiological clock of the eyes and skin, helping vascular development (especially during growth), and assisting in temperature adjustment. These functions further affect sleep quality, emotional stability and depression improvement, showing the importance of Unigroup to health.

Taking the example of myopia, the occurrence of myopia is related to poor blood circulation (ischemia) in the eyeball, while the OPN5 receptor can maintain blood flow and prevent myopia. This explains why Unigroup can effectively prevent myopia.

How important is 2 hours of daily life to health?

During the COVID-19 pandemic, a wave of epidemic prevention at home has set off in the world, leading to a surge in health problems such as myopia and depression. Professor Tingda Mingshi believes that this is related to insufficient Tsinghua. Many people still receive sunlight through windows even when they stay at home. However, why is there still a problem of insufficient purple light? The key is the barrier effect of glass. Most modern building and car windows can filter light below 400 nanometers, including purple light and ultraviolet light. In a different sentence, even if you sit by the window, your body still cannot receive the purple light, resulting in the OPN5 receptor being unable to be activated. And LED lights cannot emit such wavelength light. Therefore, if you stay indoors all day, your body will have a serious lack of purple light, which will lead to health problems.

How to effectively supplement the Universal Light?

Professor Maki Hitoda proposed the suggestion of "outdoor lighting", that is, go out to the sun every day to stimulate the OPN5 receptors in a simple and effective way. However, you don't have to stay outside like a golfer for more than half a day, and 2 hours of day is enough every day. For public servants, it may be difficult to ensure that these 2 hours of outdoor time are not easy, so some methods can be used to increase the purple light extraction:

1. After waking up in the morning, open the window first. If the weather allows, open the window greatly to expose the body to the natural light. This not only helps OPN5 activation, but also helps adjust physiological clocks and start your day more energetic.

2. Choose an outdoor route when commuting

As long as possible, avoid walking underground lanes, choose a sunny route to commute on foot, and keep your head slightly raised to allow your face to receive more purple light.

3. During the working period, increase your outdoor time

or arrive in advance before meetings or meetings, and take a walk nearby for a few minutes. Going out during lunch break, even if it's just a short time to stand in the sun for a while.

4. Set up an outdoor work space at home, Professor Masashi Hitoda himself moved his desk to the sun to create an "implementation outdoor office" to ensure that he can receive the purple light for a long time.

5. Do more outdoor activities on holidays

If outdoor activities are reduced after the epidemic, then it is time to resume habits such as mountain climbing, picnicking, jogging, and cycling to increase the intake of the Universal Light.
