It is well known that your immune system serves to protect your body from germs and viruses. But effective as it naturally is, it is only a system, not an entity and it has its flaws. That’s why normally healthy people get sick when their immune system weakens. As it is Winter time, here’s what you can do to improve your immunity.
Immune system can be improved by healthy living habits, proper diet and natural immunity boosters
Healty living strategies to adopt:
- Don’t smoke
- Take care of your blood pressure
- Eat a lot of vegetables and whole grains
- Avoid infection-wash hands and sanitize
- Maintain a healthy weight
- Drink moderately
Be skeptical when it comes to pharmaceuticals
A lot of pills are being advertised as immune boosters, and they probably are, but as immune system is a system made of so many different cells that respond to different microbes in a different way, there is no guarantee that you will be 100% protected. Many scientists are conducting researches to explore various ways of boosting immune system: nutrition, herbal supplements, exercise, lack of stress etc.
Here’s what has been established so far:
Can diet help?
Immune system needs proper diet in order to function, and the biggest proof to that is the number of malnourished people that live in poverty and are vulnerable to diseases. Although there are very few studies that tie the effects of nutrition directly to the development of the disease, there are certain minerals and vitamins that must be taken through food in order for your body to function. Here’s what a deficiency of a certain vitamin/mineral can cause in your body.
Selenium-Low selenium levels are tied to cancer (colon, bladder, breast, lung etc.).
Vitamin A- vitamin A is considered vital in our nutrition as it is said to influence certain subcategories of T and B cells and cytokines.
Vitamin B2- There are evidence that vitamin B can help you resist bacterial infection
Vitamin B6- Certain researches have shown that the deficiency of this vitamin can slow down immune response and thus make you more vulnerable to viruses. Using this vitamin as prevention has proven useful, but you must be moderate, as when taken in high doses it may help an already existing tumor to grow.
Vitamin C- Vitamin C is well known for its immune boosting abilities, but the studies that verify this fact show that it is useless to take Vitamin C alone, as it is more effective when taken with other vitamins.
Vitamin D- Researches have shown that people with tuberculosis respond well when exposed to direct sunlight, but does it help your organism fight other disease is not proven yet.
Zinc– Is essential to your immune system, as it feeds the cells and allows them to function properly, and while it is important to have enough zinc in your daily diet (15-25 mg per day) intaking too much zinc can actually inhibit your immune system.
