Strenuous exercise weakens the human body's immune system, research shows

Researchers say that immediately after intense and heavy exercise, the immune system of the human body weakens.

Most people exercise for fun to stay physically fit, but there are many professions that require vigorous exercise. Firefighting is one such field where firefighters need to exercise regularly to stay fit.

A study published in the medical journal Military Medical Research collected fluid molecules (molecules) from 4,700 firefighters after strenuous exercise and analyzed them.

According to Ernesto Nakayasu, a biomedical scientist at the Pacific Northwest National Laboratory (PNNL), who was part of the research team, analysis of the cells revealed that the subjects' respiratory systems were less susceptible to viral infections immediately after strenuous exercise. Affected. . The risk increases. This is because excessive exercise weakens the body's immune system and weakens its ability to fight invading germs.

There are numerous studies confirming the positive effects of moderate exercise on the human body's immune system, but the effects of vigorous exercise on the body's ability to fight disease are still debated.

For their research, Nakayasu and his fellow scientists collected blood plasma, urine and saliva samples from firefighters 45 minutes before and after exercise.

Analyzing these samples, the scientists concluded that the firefighters' immune system slowed immediately after exercise.
