Are there any risks to cold water swimming?
Cold water shock can occur when your body undergoes sudden immersion in cold water that is less than 15°C. It causes uncontrollable breathing and increases the work of the heart, which can lead to hypothermia and drowning. Winter swimming is not dangerous for healthy persons, but should be avoided by individuals with heart or respiratory diseases, high blood pressure and arrhythmia, as well as children and the elderly. Through conditioning, experienced winter swimmers have a greater resistance to effects of the cold shock response.cold water swimming (winter or ice swimming) has a long tradition in northern countries. Until a few years ago, ice swimming was practiced by very few extreme athletes. For some years now, ice swimming has been held as competitions in ice-cold water (colder than 5 °c).Furthermore, cold water temperatures pose additional risks to the immersed swimmer, including the initial “cold shock” and hyperventilation [18] and potential risk of hypothermia [11,12].

However, it might set off a vagus nerve response, causing a temporary slowing of the heart rate, but this is often safe for most people.By submerging yourself into cold water, your blood vessels narrow, and your heart rhythm becomes disturbed. This can put your body into shock and can cause a cardiac arrest. Always try to submerge your body gradually and try to control your breathing.Cold water swimming can improve blood pressure and fat levels in the blood when practised regularly by those in good general health. However, if you have a heart condition, there are risks you should consider and discuss with your doctor or nurse specialist before starting swimming.

And that stimulus keeps us smiling and laughing.Prolonged exposure to cold water can lower your core body temperature, leading to hypothermia. This occurs when your body loses heat faster than it can produce it, causing shivering, confusion and, in extreme cases, unconsciousness.Cold-water immersion triggers the release of important hormones and neurotransmitters, such as dopamine, serotonin, cortisol, norepinephrine, and β-endorphins, which are all linked to modulation of the neural responses to stress and other emotion-related circuits affected in depression, anxiety, and posttraumatic .
What are the negative effects of swimming?
You can get swimming-related illnesses if you swallow, have contact with, or breathe in mists of water contaminated with germs. The most common swimming-related illnesses are diarrhea, skin rashes, swimmer’s ear, pneumonia or flu-like illness, and irritation of the eyes or respiratory tract.

Can swimming in cold water affect your heart?
The shock of cold water against the skin triggers a fight-or-flight response. The adrenal glands pump out extra epinephrine (adrenaline) and other stress hormones. They cause blood vessels supplying the skin to narrow. This conserves heat, but it shifts even more blood to the chest, taxing the heart. It can exacerbate ‘cold stress’ for those in situations struggling to keep their core body temperature up. And During heat exhaustion, cold water can activate the vagus nerves (in the esophagus and stomach which control involuntary activity) leading to loss of consciousness.Cold water can also cause shock, which is a sudden drop in blood pressure that can lead to fainting or cardiac arrest. Symptoms can include pale skin, sweating, fast pulse and clamminess. The sudden rise in blood pressure caused by hypothermia and shock can be fatal for people with a pre-existing heart condition.Research from 2001 linked drinking cold water with triggering migraine in people who already experience migraine.
