How can we protect us falling sick
Answers
Most secrets to good health aren’t secrets at all, but common sense.
1. Eat green vegetables
Green, leafy vegetables are rich in vitamins that help you maintain a balanced diet — and support a healthy immune system. According to a study of mice, eating cruciferous vegetables sends a chemical signal to the body that boosts specific cell-surface proteins necessary for efficient immune-system function. In this study, healthy mice deprived of green vegetables lost 70 to 80 percent of cell-surface proteins.
2. Get Vitamin D
Reports indicate that many Americans fall short of their daily vitamin D requirements. Deficiencies in vitamin D may lead to symptoms such as poor bone growth, cardiovascular problems, and a weak immune system.
Results from a 2012 study in the journal Pediatricssuggest that all children should be checked for adequate vitamin D levels. This is especially important for those with dark skin, since they don’t get vitamin D as easily from exposure to sunlight.
Foods that are good sources of vitamin D include egg yolks, mushrooms, salmon, canned tuna, and beef liver. You can also buy vitamin D supplements at your local grocery store or pharmacy. Choose supplements that contain D3 (cholecalciferol), since it’s better at raising your blood levels of vitamin D.
Shop for vitamin D.
3. Keep moving
Staying active by following a regular exercise routine — such as walking three times a week — does more than keep you fit and trim. According to a study published in the journal Neurologic Clinicians, regular exercise also:
keeps inflammation and chronic disease at bay
reduces stress and the release of stress-related hormones
accelerates the circulation of disease-fighting white blood cells (WBCs), which helps the body fight the common cold
4. Get enough sleep
Getting adequate sleep is extremely important if you’ve been exposed to a virus, according to a study published in the Archives of Internal Medicine. Healthy adult participants who slept a minimum of eight hours each night over a two-week period showed a greater resistance to the virus. Those who slept seven hours or less each night were about three percent more likely to develop the virus after exposure.
One reason may be that the body releases cytokines during extended periods of sleep. Cytokines are a type of protein. They help the body fight infection by regulating the immune system.
5. Skip the alcohol
New research shows that drinking alcohol can damage the body’s dendritic cells, a vital component of the immune system. An increase in alcohol consumption over time can increase a person’s exposure to bacterial and viral infections.
A studyTrusted Source in the journal Clinical and Vaccine Immunology compared the dendritic cells and immune system responses in alcohol-fed mice to mice that hadn’t been supplied alcohol. Alcohol suppressed the immunity in mice to varying degrees. Doctors say the study helps explain why vaccines are less effective for people with alcohol addiction.
6. Calm down
For years, doctors suspected there was a connection between chronic mental stress and physical illness. Finding an effective way to regulate personal stress may go a long way toward better overall health, according to a 2012 study published by the National Academy of Sciences. Try practicing yoga or meditation to relieve stress.
