6 Ways Swimming Can Benefit The Immune System

Written by Dr. Sintayehu Abebe on Wed, 16 November 2022


Swimming is an exercise that keeps you strong not just physically but mentally too. Like most exercises, swimming releases endorphins into your body which help lower stress and boost immunity. The more intense the workout, the more likely you are to boost the performance of your immune system.

Improves blood circulation

Swimming keeps your blood moving and makes it easier for oxygen and other nutrients to reach your vital organs. Better circulation also improves your body's ability to eliminate waste and to ensure your organs perform at top efficiency.

Can boost white blood cell count 

Studies suggest that swimming in water that is cooler than your body temperature can increase your WBC count. This is because your body produces more white blood cells when faced with a stressor. Swimming in cold water stimulates this release, showing a significant increase in not just white blood cells, but also red blood cells and your platelet count. White blood cells are the part of your immune system that is responsible for fighting off infections. They are produced by the bone marrow and circulate throughout your body through your blood and lymph tissue.

Stimulates your immune system 

Studies have found that the benefits of swimming have a long-lasting effect on your body. Swimming helps release endorphins, combat stress, burn calories, boost your heart rate, and provide your body with an intense workout, all while being a low-impact form of exercise. Swimming keeps your blood flowing to your cells and organs, this reduces inflammation and helps your immune system do its job efficiently. So, if at all you're faced with an illness in the future, your body is more equipped with soldiers on standby to fight the viral army.

Builds internal strength 

Swimming not only gives your muscles a good workout, but it also improves your heart and lung functions. It helps lower blood pressure, regulates your breathing, and keeps your heart rate up without stressing out your body. It can be a safer option for people with arthritis, injuries, and disabilities.

Improves sleep 

As with most exercises, swimming is likely to improve and regulate your sleep. Getting a good night's rest can help improve the overall functioning of your body and mind. Swimming is a preferred choice of exercise for older individuals as it works out your body without adding any extra stress to your joints as walking and running sometimes would.

Boosts your mood 

Staying active is not just beneficial to your body but also your mind. As with most exercises, swimming releases more endorphins in your body that help boost your mood. Regular swimming of even half an hour a day can be effective in lowering cases of depression and anxiety.

Swimming is a fun activity that can be appealing to a wide range of people. It is a full-body workout that can leave you with a wide range of benefits, long after you've left the pool. So, don't hesitate to dive right in!
