More often than not, stocking up on vitamin C supplements has not been shown to effectively prevent colds. According to Dr. Bruce Bistrian, chief of clinical nutrition at Harvard-affiliated Beth Israel Deaconess Medical Center, research has shown that vitamin C is only marginally beneficial when it comes to the common cold.
Truth is, unless you're a marathon runner or a fitness enthusiast who constantly trains in low temperature, the ideal way to avoid getting sick is to build up a strong immune system.

While having a strong immune system does not completely protect you, it is the best way of staying healthy all season. Here are 3 ways which you can boost your immune system:
Method 1: Keep stress bugs at bay
Minimising stress is beneficial for your mental wellness and body. Stress suppresses the immune system, and makes it more difficult to fend off bugs.
Method 2: Get sufficient sleep
A lack of sleep forbids your body to function to its fullest potential, which ultimately impairs your immune response and makes you more susceptible to viruses.
Method 3: Go easy on the cocktails
While an occasional drink does not have a huge impact on your body, excessive drinking hinders white blood cells from ridding harmful bacteria, and damages your tissues, which leave you vulnerable to infection.
