Turning on the light to sleep may cause cancer

A new study found that people who turn on the light to sleep or who have a natural sleep pattern that is disturbed by artificial light may have a greater cancer risk than the average person.

Therefore, children are afraid at night or convenient for adults to take care of children at night and do not turn on the lights at night.

銆€銆€Researchers at the London Children’s Leukemia Congress presented an increase in the incidence of childhood leukemia and exposure to light at night.

Although researchers don’t know much about the real causes of leukemia in children, they believe that environmental factors play a major negative role in children with leukemia.

A research team led by Russell Wright, a professor at the University of Texas, said that compared with the ratio of 100 years ago, people now spend a lot of time exposed to artificial light at night.

銆€銆€At night, the natural circadian rhythm of direct light disturbs the state, and this circadian clock controls the biological processes of animals and plants that cycle for 24 hours.

This damage inhibits the normal secretion of melanin at night.

The secretion of melanin is mainly concentrated between 9:00 pm and 8:00 am.

Professor Wright said that the reduction of melanin has been associated with microbial growth and its proliferation.

Professor Wright said: “We are growing in a bright or dark environment.

銆€銆€Melanin increases dramatically at night, which helps the body rest and metabolism.

If people are exposed to artificial light at night, their ability to secrete melanin will be limited.

Once you go to bed, you should turn off the lights until you wake up the next morning.

Without melanin, carbohydrate growth and cellulose damage to DNA will increase.

As an antioxidant, melanin protects against the destruction of DNA oxidation.

Once destroyed, DNA may mutate and cancer may occur.

Professor Wright said that although there is no clear evidence that excessive artificial light is the chief culprit in the increased incidence of childhood leukemia, it is indeed a very likely cause.

He said that people think that using electro-optical light is a matter of course, but they did not think that electro-optic is a drug and is an environmental pollutant.

Excessive electro-optic does have an impact. People should be cautious when using electro-optic in their lifetime. Do not turn on the lights at night.

Children should not be allowed to sleep with lights on, and you should also be careful to turn on the lights as little as possible at night.

銆€銆€Previous studies have shown that people who work in electro-optical environments on some nights have a higher probability of developing breast cancer than ordinary people.

The study also showed that blind people may generally have lower cancer.

Because the blind people do not need electric lights at night, the secretion process of melanin is not affected.

Russell Foster, a professor of visual neuroscience at the Royal College of London, says that almost all life on Earth has the gene for a 24-hour clock that replaces the cycle.

銆€銆€Professor Russell said: “Biology clocks control or change our sleep patterns, vigilance, emotions, physical strength, blood pressure and other aspects of our physiology and behavior.

Since the beginning of the 20th century, the incidence of childhood leukemia has risen sharply, and most of the patients are children under 5 years of age.

The incidence of leukemia in children under 5 years of age increased by more than 50% in the second half of the 20th century.
