This is becauseour immune system has mobilized the production of antibodies 10 fight the invaders. After a few days, even without medication, the lynph nodes would retum to their normal size. Unhealthy lifestyle, poor eating habits, frequent use of drugs and medication lack of exercise, late nights, emotional sFess,environmental factors, use of chemicals, fiee radical activities ftom devices like mobile phones and electrical appliances can severely weaken our immune s).stem. When this happens, our body becomes easy prey to infections and diseases.Painfirl joints, swelling, poor digestion, constant coughsand colds are symptoms of a weak immune sysl€m. Deficiencies and imbalancesin nutrients can disrupt the proper functioning of our irnmune system. Zinc, which is important in immune mechanism, is one of the most commonnutrient deficiencies.An adequatelevel ofbeta-carcteneand vitamin A is important to help our body ward off invaders, and vitamins C and E are the most important immune protectors.
