Who should avoid swimming in bodies of water?

During the hot summer months, swimming in ponds, lakes, and seas to cool off and relieve stress is a very common activity. However, this activity is not equally safe and risk-free for everyone. For individuals with certain health conditions, being in natural bodies of water can pose serious dangers. Therefore, health authorities and experts regularly warn that groups with specific conditions should avoid swimming in these areas.

Individuals with heart and circulatory system conditions are among the first groups that should stay away from such activities. The sudden shock effect of cold water on the body can lead to dangerous heart rhythm disorders and even sudden cardiac arrest. Additionally, it is extremely difficult to intervene if patients with chronic conditions such as heart failure or high blood pressure experience a crisis in the water. Therefore, swimming in open or natural waters poses a major health risk for individuals with cardiovascular problems.

People with weakened immune systems should also be careful not to enter bodies of water due to various infection risks. Natural waters can contain many different types of bacteria and viruses, ranging from urinary tract infections caused by fecal matter to severe stomach illnesses. Immunocompromised patients, those undergoing cancer treatment, or organ transplant recipients are extremely sensitive to these microbes. For this group of people, even clear-looking water does not mean it is free of germs; therefore, even the smallest infection can create a life-threatening situation.

It is also not appropriate for individuals with impaired skin integrity, open wounds, or severe burns to swim in environments such as lakes or seas. Bacteria living in natural bodies of water can easily enter the body through open wounds, causing rapidly spreading infections. These microorganisms, which multiply rapidly with heat especially during the summer months, can cause damage leading to cell death or tissue loss. In this case, it is essential for individuals with any cuts, abrasions, or surgical stitches on their bodies to prefer clean environments instead of bathing or pools until the healing process is complete.

Finally, older adults, pregnant women, and young children must also be very careful when swimming in such areas. While elderly individuals are intolerant to sudden temperature changes, pregnant women need to be protected from waterborne infections. Considering all these factors, the importance of making a personal assessment based on health conditions is highlighted once again, even though swimming in natural bodies of water is an enjoyable activity. Everyone with questionable health status is strongly advised to consult a doctor before participating in the activity.
