• Winter swimming may be risky to individuals who are not used to swimming in very cold water. After submersion in cold water the bloodless surprise response will occur, causing an uncontrollable gasp for air. This is observed through hyperventilation, an extended period of more speedy breathing. The gasp for air can purpose someone to ingest water, which ends up in drowning. As blood within the limbs is cooled and returns to the coronary heart, this could purpose traumatic inflammation and consequently cardiac arrest. The bloodless shock reaction and cardiac arrest are the most common causes of death related to cold water immersion.

• Winter swimming isn't risky for healthful persons, but need to be prevented by way of individuals with coronary heart or respiration sicknesses, weight problems, high blood strain and arrhythmia, as well as youngsters and the elderly. Through conditioning, experienced winter swimmers have a more resistance to results of the bloodless surprise reaction.

• Hypothermia poses a smaller chance. According to Tucker and Dugas, it takes greater than approximately half-hour even in zero °C (32 °F) water till the frame temperature drops low sufficient for hypothermia to occur. Many human beings would probably be capable of live to tell the tale for nearly an hour. There is not any consensus on these figures however; consistent with special estimates someone can continue to exist for 45 mins in 0.3 °C (32.5 °F) water, however exhaustion or unconsciousness is expected to occur inside 15 minutes. Consuming alcohol before winter swimming have to be prevented as it speeds the onset and development of hypothermia.

• Care have to be taken when iciness swimming in swimming swimming pools and seas close to the polar areas. The chlorine delivered to water in swimming pools and the salt in seawater permit the water to stay liquid at sub-zero temperatures. Swimming in such water is significantly extra hard and dangerous. The skilled iciness swimmer Lewis Gordon Pugh swam close to the North Pole in −1.7 °C (28.9 °F) water and suffered a frostbite injury in his palms. It took him four months to regain sensation in his palms.
