8 scientific discoveries that everyone who wants to be healthy should knowBy Vika https://pictolic.com/en/article/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 dramatically change our medical knowledge. For example, experts recently concluded that sometimes it is better to sit with a bent back than with a straight back. Plus, working in a nail salon is just as harmful as working in a refinery.
We learned about scientific discoveries that can have a positive impact on our lifestyle.
1. Appendectomy can lead to Parkinson's disease.
Case Western Reserve University in Cleveland analyzed a medical database containing information on 62.2 million patients. It turned out that people who underwent appendectomy had Parkinson's disease 3 times more often. Experts do not know the exact connection between disease and surgery, but it is clear that there is some connection between the two.
2. Working in a nail salon is just as harmful as working in a refinery.
Scientists from the University of Colorado spent 1.5 years studying air quality in 6 different nail salons in Colorado. They measured the concentration levels of formaldehyde as well as benzene, toluene, ethylbenzene, and xylene. It was found that in all 6 nail salons, the concentration of these toxic elements was many times higher than the norm, which increases the risk of developing nasopharyngeal cancer, leukemia, and other types of cancer. In addition, a questionnaire survey revealed that the majority of employees in these salons suffer from skin and eye irritation and headaches. Experts estimate 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 at a refinery. At the same time, the researchers noted that clients have nothing to worry about as long as they don't have asthma or allergies.
3. The blue LED is harmful to the eyes.
French experts from the National Agency for Food, Environment, and Labor Control have found that blue light emitted by LED lamps and other devices has negative effects on human health. In particular, it leads to disruption of circadian rhythms and has a negative effect on the retina of the eye. 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 slowly kill the human heart.
Doctors at the University of Massachusetts Medical University conducted a study and proved that the flavors in the vapors are harmful to the cells in the vessels of the heart. As it turns out, aromas cause inflammation and even death of certain heart cells. 6 flavors have been tested and the most dangerous of them was the cinnamon-flavored liquid. By the way, 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 your back straight.
It is believed that when sitting, the back should be straight. But recent research suggests that this idea is flawed. Physiotherapists at North Tees University Hospital in Stockton-on-Tees conducted their own investigation and concluded that a slightly bent back may be beneficial for those with lower back pain.
6. Humidifiers protect us from the flu.
Scientists at Yale University have found that air humidity affects the body's response to the influenza 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 areas with lower humidity were more prone to infection with the virus. It is also worth noting that under the same conditions, airway regeneration slowed down after infection. Scientists are convinced that humidifiers should be used to reduce the risk of getting the flu. And not only at home, but everywhere.
7. Neck kneading is very dangerous for your health.
Doctors warn us that if you stretch your neck a lot, trying to stretch it, you can get serious health problems. Doctors refer to a case that recently happened 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 crackling sound 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 a stroke: when he stretched his neck, John tore open arteries going to the bone of the neck, 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 is also interesting that he continued to hiccup for 2 weeks after he had a stroke.
8. Exercise is 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, exercise in the morning is better for your metabolism, and therefore more effective.
