What are the effects of frequent exposure to fluorescent lights on the body and how can it be allevi

Nowadays in the city, this situation is very common for you, there is no obvious effect on the human body, and there are no reports of illness due to fluorescent light exposure.

The main reason why fluorescent lamps affect eyesight is because of the "flickering" of fluorescent lamps. This kind of high-frequency flashing can easily make the eyes tired, and in order to see the words clearly, they often unconsciously bury their heads lower, which naturally causes or aggravates myopia. In addition, the flickering light will cause another kind of damage to the eyes when they are forced to adapt——— resulting in astigmatism.

Fluorescent lamps are bright because of their white color, which often makes people feel that the light intensity is enough, but in fact, the fluorescent lamp table lamp of about 8 watts, or the fluorescent lamp of only about 20 watts in the room, the brightness and intensity of its lighting are far from enough. Of course, if it's just the usual lighting, it may be fine, but when used as a table lamp, it is harmful to the eyes.

Therefore, it is recommended that fluorescent lamps should be used in combination with incandescent lamps, so that the light is soft and can protect the eyesight.

It is better to use cold water and ice face or use a hot compress such as a towel, it depends on each person's physique, it is better to be able to adapt to cold water and ice face, and people with cold constitution should still use hot towel compresses, hard cold water and ice face, easy to get sick.

I think omnivorous food is the best, not picky eaters, eat a little bit of everything, nutrition is more comprehensive.

The fast pace of the current society has led to more and more people staying up late to work with lights. At the same time, in many modern buildings, it is necessary to turn on the interior lighting to work, even in broad daylight. In this case, the harm of light to the human body must attract our sufficient attention.

Scientists have known for a long time that bright light can alter the brain's internal clock, which in turn controls a person's sleep. A recent study has shown that ordinary indoor light can also affect the body's biological clock.

The long-term use of indoor lighting has invisibly disrupted the biological clock set by the ancestors for people, so as to change the inherent physiological pattern of the human body. This will not only advance the age of maturity of human beings, but also make people's physiological rhythm disordered, and then appear palpitations, chest tightness, mental malaise and other phenomena. Other researchers believe that the strong light waves emitted by indoor lighting can cause genetic degeneration of a large number of cells in the human body, causing the increase of abnormal cells and the death of normal cells.

Working under light for a long time not only causes eye fatigue, but also reduces the body's ability to absorb calcium. Because there is a big difference in the nature and intensity of light and sunlight. Natural light contains many colors and wavelengths, while indoor lighting only has yellow, orange and red, and lacks the beneficial ultraviolet rays in sunlight, so the absorption of calcium is greatly reduced.

In addition, the light emitted by the fluorescent lamp has blue and invisible ultraviolet rays, which are overabsorbed by the human body and are likely to make people's ** cancerous.

For this reason, experts recommend that it is best to make use of natural light during the day, and to open windows frequently to let sunlight indoors; People who work at their desks all day long in the office should take time out to avoid contracting modern lighting diseases.

When indoor lighting must be used, the following five principles should be grasped: use a wide range of lighting, such as when reading a book on a desk, the light should shine on the entire desktop; Use uniform lighting, which means that the illumination of each part of the illuminated place should be consistent; Maintain stable lighting, and the light source should not be dim or flickering; There is no uniform standard for maintaining adequate lighting, which generally depends on the nature of the work, that is, the finer the work, the higher the illumination required; Finally, be careful not to let the light shine directly into your eyes.

Working under the lights every day, as long as it's not night, has no effect on the body. Nighttime lighting can disrupt the body's biological clock, causing black and white to be reversed, and eating at night when it shouldn't be eating, so it can lead to obesity.

Nighttime lighting includes both turning on the lights and the low light produced by a TV or computer. Therefore, regardless of the intensity of the light at night, as long as there is light, it may increase the chance of obesity. And sleeping with the lights off at night helps**.

Short-term exposure to strong sunlight is generally not harmful to the human body, but if exposed to strong sunlight for a long time, it may lead to sunburn, aging, allergies, and even lead to cancer.

1. Hazards: 1. Sunburn: Long-term exposure to strong sunlight may cause burns and burns, resulting in dehydration, peeling, pain, etc. Ultraviolet rays and strong sunlight can also cause damage to the eyes, causing symptoms of tearing, redness, swelling, and pain, and in severe cases, retinal cells may be damaged, causing irreversible effects;

2. Aging: Light will cause natural aging, and long-term strong sunlight exposure will accelerate aging, so that wrinkles, roughness, spots, sagging and other aging manifestations will gradually appear;

3. Allergies: strong sunlight contains a lot of ultraviolet rays, which has a certain amount of damage, and long-term exposure may lead to ultraviolet allergies, especially for more sensitive people, who are more likely to have this situation, with symptoms such as erythema and pimples, and can be accompanied by itching, pain, etc.;

4. Cancer: Long-term strong sun exposure may lead to actinic keratosis, skin lesions can form crusts, and even induce squamous cell carcinoma.

Second, the protection method:

1. Physical protection: sunhats, parasols, sunglasses, ice sleeves, etc. on the market are good protective items, which can well isolate the contact between the human body and ultraviolet rays at the physical level, and can also isolate a certain amount of light and temperature from damage to the eyes and eyes, which is a cost-effective and effective protection method;

2. Chemical protection: The chemical molecules in the chemical sunscreen will be absorbed, which will absorb ultraviolet rays inside the body and be removed by the body's metabolism, which is an effective way of protection. Different brands of chemical sunscreens have different ingredients, **Fragile and sensitive people may not be suitable for choosing chemical protection methods, and it is recommended to use them under the guidance of a doctor.

There is a limit to everything. Prolonged exposure to light may lead to adverse consequences, including neurasthenia, circadian clock disorders, impaired vision, and more.

Long-term exposure to light is harmful to the body, and long-term exposure to outdoor lights is more harmful to the human body.
