8 scientific discoveries that everyone who wants to be healthy should know

If we want to have a long and healthy life, we must keep abreast of the latest scientific research in the field of medicine. This is because the result of such research can greatly change our knowledge in the field of medicine. For example, recently experts have come to the conclusion that sometimes it is better to sit with a bent back than with a straight one. Besides, working in a nail salon is just as harmful as working in an oil refinery.

We learned about scientific discoveries that can have a positive impact on our lifestyle.

1. Appendectomy can lead to Parkinson's disease.

Experts from Case Western Reserve University in Cleveland analyzed a medical database containing information on 62.2 million patients. It turned out that people who had an appendectomy were 3 times more likely to have Parkinson's disease. Experts do not know the exact link between the disease and the operation, but it is clear that there is some connection between them.

2. Working in a nail salon is just as bad as working in an oil refinery.

Scientists from the University of Colorado spent 1.5 years studying air quality at 6 different nail salons in Colorado. They measured concentration levels of formaldehyde, as well as benzene, toluene, ethylbenzene, and xylene. It was found that in all 6 nail salons, the level of concentration of these toxic elements was many times higher than the norm, which increases the risk of developing cancer of the nasopharynx, leukemia and other types of cancer. In addition, a questionnaire survey showed that the majority of employees in these salons suffer from skin and eye irritation, as well as headaches. Experts have calculated that if a person breathes this air for 20 years, the risk of developing cancer is 100 times higher, and working in a nail salon is the same as working in a garage or an oil refinery. At the same time, the researchers noted that clients have nothing to worry about if they do not have asthma or allergies.

3. The blue LED is dangerous to the eyes.

French experts from the National Agency for Food, the Environment, and Labor Control have found that the blue light emitted by LED lamps and other devices has a negative impact on people's health. In particular, it leads to disruption of circadian rhythms and has a negative effect on the retina. Children are especially at risk because the lens in their eyes is not yet fully formed. Experts recommend using lamps that emit a warm light.

4. Vapes are slowly killing the human heart.

Doctors from Massachusetts Medical University conducted a study and proved that flavors in vapors are harmful to cells in the vessels of the heart. As it turned out, aromas cause inflammation and even death of certain heart cells. 6 flavors were tested, and the most dangerous of them was the cinnamon-flavored liquid. Incidentally, last year experts also found a link between vaping and an increased risk of a heart attack.

5. You don't always have to sit with a straight back.

It is believed that when sitting, the back should be straight. But recent research shows that this idea is wrong. Physiotherapists at North Tees University Hospital in Stockton-on-Tees did their own research and concluded that a slightly arched back could be helpful for those with lower back pain.

6. Humidifiers protect us from the flu.

Scientists from Yale University have found that air humidity affects the body's response to the flu virus. Experts conducted an experiment with genetically modified mice that react to the flu virus in the same way as humans. Animals kept in rooms with the same temperature but different humidity was exposed to the influenza A (H1N1) virus. Organisms that were in places with lower humidity were more likely to become infected with the virus. It is also worth noting that under the same conditions, the regeneration of the respiratory tract slowed down after infection. Scientists are convinced that humidifiers should be used to reduce the risk of contracting the flu. And not only at home, but everywhere.

7. Neck kneading is very dangerous for your health.

Doctors warn us that if you knead your neck too much in an attempt to stretch it, you may have serious health problems. Doctors refer to a case that recently occurred with 28-year-old Josh Hader. His neck hurt, and to improve the situation, he began to stretch his neck and tilt it from side to side. Suddenly, he heard a crack and Josh felt the left side of his body go completely numb. He also felt weak, began to hiccup non-stop, and had problems with coordination and vision. At the hospital, doctors discovered that he had suffered a stroke: when his neck was stretched, John severed the arteries leading to the neck bone, where the neck connects to the skull at the base of the brain. He spent several days in the hospital. Today he is at home, but he still has problems such as lack of coordination. It's also interesting that he continued to hiccup for 2 weeks after he had his stroke.

8. Workouts are more effective in the morning.

A new study by scientists from the University of California has shown that exercising in the morning is much more effective than in the evening. It turns out that in the morning our cells consume more oxygen, and metabolic processes are activated in the body. Thus, exercising in the morning is better for your metabolism, and therefore more effective.
