We all know people who never get cold, even if everyone is sneaking and suffering. They may have a long -standing secret of rich health. Well, or all the secret in healthy habits. Studies show that you can also strengthen the immune system and become a real superhero, invulnerable to bacilli and viruses.
Steal the time of sleep? You will also steal health. Researchers found that people who slept less than seven hours a day were three times more likely to have colds than those who slept for eight hours. Summarize: seven to eight hours are optimal, no longer worth it, less. The flu vaccine is effective in 50-60% of cases, and if you are still infected, the symptoms will not be so severe. Moreover, studies are shown, a third vaccine reduces the risk of heart attack, stroke, heart failure, or other serious heart problems (including death!). Even if the vaccination is not perfect for a topical flu strain, you will still be partially protected. From childhood, we know that smoking badly, smoking is harmful, we need to throw it if we started. But people still smoke. And it is very in vain, because those who have quit this bad habit (or never started) get sick much less. Cigarette smoke damages the mucous membranes that work as the first barrier from infections, and as a result, smokers are cold about twice as often more than people of non -smokers (and the flu is sick and more!). Smoking also inhibits the entire immune system, which not only leads to heart disease and lungs, but also promotes the development of bladder cancer, blood, cervix, rectum, esophagus, kidneys, larynx, liver, lungs and other organs. A study by oncologists showed that postmenopausal women who regularly exercise are less likely to get a cold compared to women who lead a less active lifestyle (not sitting-just less active). In the first year, there were about twice less colds than the second. Physical activity helps to increase immune cells in the blood and saliva. 45 minutes a day, five days a week, and everything will be great. Microbial threats can be washed away with ordinary soap and warm water. Antibacterial soap is not necessary and even harmful: the study showed that people who used such harsh remedies were no less cold than those who wash their hands with ordinary soap. It is not necessary to rub the palms of dryness and cracks maniacly, but when you come from the street and before eating - necessarily. And at least 20 seconds. A healthy social life can help you keep your health. Researchers from Carnegie-Mellon have infected the cold virus and monitored who was the first. To their surprise, people are sootal often - with a wide range of friends and acquaintances, who more often go outside and communicate with people. This phenomenon is not only a common cold - if people with strong social ties face difficulties, they are less likely to get sick and even die than the reclusions. Researchers associate results with anti -stress protective effect. We are known to be social creatures. A favorite comedy can help your body. Surprised? In one American study, healthy women who watched videos with their favorite comedians showed unusually high activity of the body's nk cells. These are lymphocytes that fight the infection, they are also called "natural killer". Women who watched a video about tourism had no similar effect. However, they may have been very sad videos, and the subjects did not go on vacation for a long time.
In the same study, it turned out that satisfied relaxed people get sick about three times less often than those who suffer from depression, anxiety and stress. This is quite simple: a positive attitude to life reduces the level of stress hormones (cortisol, for example), which weaken the body's defenses. In other words, rejoice so that the bacteria shudder!
