Many people love New Year’s Eve not only for the upcoming holiday, the expectation of a children’s miracle, but also for sparkling garlands, sparkling Christmas trees. Looking at the cheerful lights one cannot help but get into the spirit of the New Year.

And psychologists recommend decorating houses brighter, hanging more garlands to combat sadness and depression. Indeed, in the dark season, bright lights prolong the day and cheer up, invigorate.

But it turned out that, only with bright lights, not everything is so simple.


Some time ago, the French National Agency for Food Safety, Environment and Work (ANSES) carried out an examination of blue LEDs. And it turned out that flashing blue light negatively affects the retina, which is sensitive to ultraviolet radiation. If you look at the blue LEDs for a long time, you can get tangible damage to the retina.

In fact, light from the ultraviolet spectrum was investigated. Naturally, the dangers of ultraviolet radiation, including for the retina, have long been talked about. But our ophthalmologists reassure us: the garlands we buy in stores are certified. They are checked, including the brightness and degree of illumination.

In addition, as Ph.D., ophthalmologist Sergey Khomyakov explains, “the intensity of the light flux from the blue garlands is extremely low. The retina has a powerful antioxidant system, so even with many hours of exposure to that light, it will not be damaged.


But neurologists recommend not to abuse intermittent modes. A small percentage of people may experience so-called photosensitive epileptic seizures. And even develop photosensitivity (light-sensitive) epilepsy, a condition in which high-intensity flickering light triggers epileptic seizures. Fortunately, there are few such people.

Although the flashing mode is somewhat distracting, especially if the garland is large, bright, hanging on the window, constantly attracting attention. As Dr. Khomyakov said: “It is advisable to use garlands in one place, for example, on a Christmas tree, and not hang them on the walls and ceiling. Or the impact of such total lighting with garlands should not exceed a couple of hours a day.

In addition, the doctor recommended turning off all the garlands two hours before going to bed so that “circadian rhythms are not disturbed” (our biorhythms, according to which we must fall asleep after dark, and the garlands prolong and color our daylight hours). Or you can reduce the light content of the short-wavelength blue-violet range in them so as not to disturb biorhythms.

In general, ophthalmologists recommend the use of warm light and a continuous glow of garlands. “The blinking mode has a negative effect on cortical activity, it causes arousal, it causes visual fatigue,” ophthalmologist Tatyana Shilova told the Zvezda TV channel. “If we are talking about some warm colors, then this irritation is less, and red light is considered exciting, it has a negative effect, especially when we look at the garlands for a long time at night.”


1. Look for GOST.

GOST R IEC 598-2-20-97 must be indicated on the certified product. It obliges manufacturers to produce garlands with technical characteristics and voltage standards that are safe for the eyes.

2. Use constant current lamps to avoid voltage fluctuations and flicker.

3. Choose garlands with warm colors and adjustable brightness levels.

4. Please control the timing of the garland and don’t leave it on all the time.

If on the street or indoors, seeing a flickering garland, you suddenly feel dizzy, your eyes begin to blink involuntarily, dots appear, you immediately turn around and leave. After a few minutes, the unpleasant symptoms should disappear.


Bright street lights can cause diabetes

As Professor, Academician of the Russian Academy of Sciences, Honorable Doctor of the Russian Federation Oksana Drapkin writes on her TG channel, “According to the results of a study conducted in China, high-intensity outdoor lighting at night was associated with a higher prevalence of diabetes in the population.”

That is, if a bright flashlight shines into your windows and interferes with sleep, then circadian rhythms are disturbed and normal sleep is disrupted.

According to the study authors, on average, for every 42 people living in areas of China with the strongest outdoor artificial lighting, there was one case of diabetes, which would not be present if the same people lived in areas with the lowest levels of outdoor lighting. Turning on. The authors estimate that more than 9 million cases of diabetes in Chinese adults may be related to exposure to outdoor artificial lighting.

And extra light affects the increase in blood pressure and low-density lipoprotein cholesterol, the development of coronary heart disease and obesity.

Of course, no one has canceled our love for fatty and sweet foods, lack of physical activity, but still it is worth paying attention to the night and the street lamp. If it interferes, it is worth buying blackout curtains that will improve the quality of sleep.
