Improved Neutrophil Function, Reduced DNA Damage and Better Lymphocyte Function

Improved Neutrophil Function

Neutrophils belong to the group of cells referred to as phagocytes, which engulf and destroy waste of harmful substances in the body. Leading a sedentary life has a negative effect on the immune system wherein the activity of the immune cells is reduced. This may be attributed to sluggish blood flow.

A study conducted in Spain reported that introduction of exercise in sedentary women resulted in an increase in immune activity. The study noted the actions of the neutrophils were increased to a significant extent following the initiation of exercise therapy. The ability of the neutrophils to engulf and kill harmful microorganisms was improved, and it was found the release of certain chemicals that signals the accumulation of immune cells was also increased.

Reduced DNA Damage

A study conducted in Malaysia upheld the benefits of Tai Chi on the immune system. The researchers noted that with prolonged practice Tai Chi resulted in improvements of the immune system. Older individuals are more prone to infections owing to the reason that the immune system tends to slow down as age progresses. Investigators of the study noted that older individuals who had been performing Tai Chi for a long duration of time had better immune cells, when compared to other adults. The immune cells had a higher concentration of normal DNA with less concentration of damaged DNAs. The study also revealed that regular exercises help in the removal the old lymphocytes and replacing them with newer lymphocytes.³

Better Lymphocyte Function

Lymphocytes form a major part of the immune system and are essential for the identification and destruction of harmful microorganisms. The efficacy of the lymphocytes and associated cells are notably reduced as age progresses. Performing regular exercise was noted to improve the functioning of the T-lymphocytes and helper cells in a study conducted in Japan. Proper regulation of the immune system can prevent the risk of developing infections and reduce the severity of a disease.
