Vitamin D Deficiency
Someone who gets colds or the flu often may have a Vitamin D deficiency. People with low Vitamin D levels are more prone to catching the flu or colds because the body’s T cells rely on the Vitamin D receptor gene to work properly. Increasing your Vitamin D intake is an easy way to increase your body’s immune system.
Exposure to the sun is a great way to increase Vitamin D. Just six or seven casual exposures to the sun in a week’s time can make up for a period of up to 49 days without sun. Dairy products and other foods, such as fish and mushrooms, are all great ways to increase your Vitamin D intake.
Regular exercise promotes the circulation of immune cells through a person’s body. This type of circulation makes your body more likely to fight off infections. In fact, people who exercise at least 30 minutes a day, 5 days a week are much less likely to get sick with a cold or the flu than people who do not exercise at all.
The type of exercise a person takes part in is not important when it comes to building your immune system because any type of exercise will naturally increase the body’s production of T-cells. A high T cell level is important in creating a strong immune system. This means whether you like to jog or take leisurely walks, you can decrease your chances of getting sick by doing any type of exercise you choose.
