Brisk Walking 
Whether you are running errands for your boss or shopping for groceries, walking is excellent for the immune system. According to Dr. David Nieman of the Appalachian State University, those who walk for a minimum of 40 minutes per day take half as many sick days as their colleagues. So quit sitting and start walking!
Yoga
Did you know that yoga was developed over 5,000 years ago by the Indus-Sarasvati civilization in northern India? The word “yoga” was first mentioned in the Rigveda, one of the world’s oldest sacred texts. This ancient form of exercise for the body and mind improves flexibility and strength while lowering stress.
Psychological stress may increase the chances of catching a cold. Yoga helps to lower stress hormones and calm the nervous system, which, in turn, strengthens the immune system. By inducing relaxation, the nervous system can inform the immune system to stop attacking foreign bodies, which will be cleared out naturally given some time.
Cycling
Invented in the early 1800s by a German civil servant, bicycles have evolved beyond their intended purpose as a means of transportation. Nowadays, riding a bicycle for leisure is a popular sport for people to become fitter and maintain a healthy immune system.
In a study published in the British Journal of Sports Medicine, it was concluded that taking part in exercises like cycling can help boost the number of immune cells circulating in the body, which may help resist against diseases. Although the effects are temporary, cycling regularly may reduce the overall chances of falling prey to the common cold and contribute to maintaining a healthier immune system.In a study published in the British Journal of Sports Medicine, it was concluded that taking part in exercises like cycling can help boost the number of immune cells circulating in the body, which may help resist against diseases.

Recreational Sports
Joining a recreational sports team that combines exercise with a bit of fun and teamwork could be beneficial to you—working together as a team increases morale while reducing stress. Due to the adrenaline-filled nature of recreational sports, your pent-up stress is released through engaging in team play.
According to Dr. Mark Ridgewell, a doctor at Sport Wales, engaging in a moderate amount of recreational or competitive aerobic exercise can strengthen the body’s rate of recovery by enhancing blood circulation.
Tip: Don’t forget to wash your hands after each match to help prevent illnesses and spread of infections to others!
Healthy Diet
Although exercising regularly may aid in boosting the immune system, the body needs good and regular nutrition to stay healthy. According to an article published in the journal Clinical Infectious Diseases, malnutrition is the primary cause of immunodeficiency around the world.
The principles of Nutritional Immunology suggest that your daily diet has a direct impact on the performance of your immune system, as well as the way you look, feel, and behave as a whole. Nourishing your immune system with a wide variety of plant-based foods daily enables it to perform optimally and defend your body against foreign invaders.
These articles are inspired by Dr. Jau-Fei Chen, the founder of E. Excel and tireless advocate of Nutritional Immunology. Nutritional Immunology is a science that studies the link between nutrition and the immune system. It believes that a healthy immune system can better prevent diseases and help the body stay healthy.
