Can You Get Sick from Swimming in Cold Water? Risks & Effects

Swimming in cold water is a popular activity enjoyed by many enthusiasts around the world. Whether it’s a brisk dip in a chilly lake or a refreshing plunge in the ocean during winter, the experience can be both exhilarating and refreshing. However, amidst the thrill of cold water immersion, a common question often arises: Can you get sick from swimming in cold water?

It involves immersing oneself in water with temperatures typically below 15 degrees Celsius (59 degrees Fahrenheit). Advocates tout its potential health benefits, including increased metabolism, improved circulation, and a boost to mental well-being.

Despite its growing appeal, concerns persist about the potential health risks associated with this activity. Let’s explore further to uncover the truth behind these concerns.

Effects of Cold Water On The Body

Cold water can cause several effects on the body when you include:

Cold shock: Sudden immersion in water below 60°F can cause a rapid increase in breathing, heart rate, and blood pressure. This can lead to disorientation, loss of consciousness, and an increased risk of drowning.
Increased blood flow: When the body is exposed to cold water, it goes into “survival mode” and increases blood flow circulation. This delivers oxygenated blood to areas of the body that need to recover.
Metabolism changes: Cold exposure can cause white fat to turn into brown fat, which can temporarily increase metabolism.
Cold-stimulus headaches: Also known as ice cream headaches, these are caused by unusually cold substances passing over the palate and back of the throat.

Risks Associated with Cold Water Swimming

While cold water swimming offers many benefits, it’s not without its risks of getting sick. Cold water can cause health risks such as:

Hypothermia: Cold water can lower body temperature, leading to shivering, confusion, drowsiness, and slurred speech.
Cold incapacitation: Cold water can cause cold incapacitation, which affects muscles and coordination.
Infections and contaminants: Swimming in open water can expose you to harmful bacteria, viruses, parasites, and chemicals.
Heart and Blood Pressure Issues: Cold water may cause an unexpected spike in heart rate and high blood pressure. This increase can cause heart failure and stroke in vulnerable people. [Source]
Cold water urticaria: This is a disorder where hives or large red welts form on the skin after exposure to a cold stimulus. The welts are usually itchy.

Other risks include:

After drop: This is when you feel colder after you get out of the water than you did when you were in.
Cardiac arrhythmias: At 33 °C, cardiac arrhythmias can occur.
Poor perfusion of the skin: At 33 °C, poor perfusion of the skin can occur.
Clouding of consciousness: At 33–30 °C, clouding of consciousness can occur.
Spontaneous shivering stops: At 33–30 °C, spontaneous shivering stops can occur.
Rigid muscle tone: At 33–30 °C, rigid muscle tone can occur

Myth vs. Reality: Can You Get Sick From Swimming in Cold Water?

There’s a common belief that swimming in cold water can make you sick. However, the reality is more nuanced. While cold water immersion can temporarily weaken the immune system and increase susceptibility to infections, it’s unlikely to cause illness in healthy individuals directly.

Cold water itself does not make you sick** unless it is so cold that you suffer from hypothermia. While many swimmers believe they might catch a common cold or the flu from swimming in cold water, it’s the bacteria and viruses** that live in the water that can cause illnesses such as the flu or the common cold.

However, the greatest health risk associated with cold water is hypothermia. Hypothermia occurs when your body temperature drops below 35°C (95°F), and it can be a serious medical emergency. Always take care when swimming in water that is less than 21°C (70°F), as this is the threshold where hypothermia risk increases.

Health Benefits of Cold Water Swimming

Despite the potential risks of getting sick, cold water swimming offers many health benefits. The cold water stimulates circulation, improving blood flow to muscles and tissues. Cold water swimming can have more health benefits, including:

Improved circulation: Cold water causes blood vessels to constrict, which improves circulation and delivers oxygen and nutrients to muscles and organs.
Better heart health: The cold water makes the heart work harder to circulate blood, which can improve cardiovascular health.
Reduced stress: Cold water swimming can help you take a break from everyday life and stressful events, which can improve your physical and mental health. Cold water also activates endorphins, which can make you feel good.
Increased calorie burning: Your body works harder to keep your core temperature up in cold water, which can help you burn more calories.
Reduced inflammation: The cold water constricts blood vessels, which can reduce inflammation by decreasing blood flow to inflamed areas.
Improved concentration and memory: Cold water swimming can improve concentration and memory function. [Source]
