With no doubt, regular and adequate physical activity positively influences the functioning of the immune system and that is how it plays such an important role in the weakened immunity and subsequent disease prevention. During adequate physical activity the immune system gets stronger and it is a prevention of the immune deficiency as well as it decreases the risk of allergies and cardiovascular diseases. Intensive and very frequent sport activity has opposite effects - physical performance and overtraining exhaust and weaken the immune system, which causes a higher susceptibility to diseases.
After a physical performance the capacity of the body to respond to antigens (foreign substances) and to produce antibodies is temporarily lower. If during this time (3-12 hours) more physical activity occurs, the resistance of the body decreases significantly. Stress and shock weaken the immune system too; the physical activity alone launches unwanted stress mechanisms that produce free radicals. Also stress caused by mental strain is not beneficial for the immunity. Sportsmen have a deficiency of antioxidants, which fight against free radicals, even a special diet is unable to cover all the needs of a trained organism and it is necessary to supply antioxidants in another way such as taking the right natural food supplement to boost the immune system. If not, excessive physical activity with insufficient intake of antioxidants can significantly weaken the immune system and exhaust the organism, which can result in chronic fatigue syndrome or development of tumor growth with the consequent elimination from the sport activity.
Healthy lifestyle, gradual increase of training activity, elimination of physical and mental overload, sufficient relaxation and boosting the immunity with the right food supplements represent a good prevention of the immunodeficiency for active sportsmen. A lot of meal plans for athletes often include many food supplements and high doses of vitamins, particularly of vitamin C. Acute surfeit of vitamin C can cause unpleasant problems such as heartburn or nettle rash. These high doses don’t have much relevance, the body does not stock the vitamin C and it is often eliminated without use in urine. Although its effects on immunity boosting are well known and very valued, it is more suitable to choose a product with a strong active ingredient that strengthens immunity and supplies missing antioxidants. The natural food supplement chosen this way efficiently decreases unwanted effects of free radicals and supports anti-cancer activity of the immune system. Except that, such product is an important prevention of the fatigue syndrome and viral diseases.
