How Exercise Can Build a Better Immune System

You’ve heard it a million times, “exercise is good for your health”. Yet you’re also probably asking yourself these questions, “Can it actually help to ward off respiratory illnesses?” or “Should I continue exercising during a global pandemic?”.

In short, YES.

A recent review published in the Journal of Sport and Health Science found that obesity and lack of activity can lower proper function of the immune system. Findings showed that practicing a healthy lifestyle can help to boost the immune system’s ability to seek out infection within the body which may reduce mortality rates from respiratory illnesses.

In addition, exercise benefits your immune system by increasing blood flow which helps to clear bacteria out of your airways and by causing a brief rise in body temperature that may be protect and strengthen antibodies to help fight infection.

A 2019 scientific review concluded that moderate-intensity exercise is linked to lower rates of upper respiratory tract infections, which includes viruses like the flu and common cold. 

Another 2018 study found that the 390 volunteers who followed an eight-week training program reduced their risk of acute respiratory illness by 14% and their number of sick days by 23%, compared with people who did not follow the training program. 

According to guidelines from the Centers for Disease Control and Prevention (CDC), healthy adults should aim to get at least 150 minutes of moderate exercise each week. During these times when social distancing can make you question your choice to enter a gym, rest assured that if done in a clean, safe environment, like B5, you will only be helping to build a stronger immune system to combat such respiratory illnesses. We strive to meet and exceed all safety requirements set in place and getting/keeping you healthy is our mission.
