Can You Swim In The Cold Water?
Yes, you can, as long as you can bear it. When the weather began to turn cold in some countries, many swimmers had to switch to other activities because they were afraid to soak in the freezing cold water. That is very sympathetic because getting into cold water is a real challenge and sometimes quite dangerous if we do not have background knowledge on the subject.
Therefore, we need to master some of the body reactions and water activities in accordance with the following water temperature ranges from high to low:
1. From 30 ° C to 34 ° C (warm-hot water)
These high temperatures are suitable for exercise activities for babies and children, the elderly, the frail, thin, or injured. For children, this temperature helps to keep their bodies comfortable in their new environments, to keep their muscles warm and fluid, and to prevent any shortness of breath that may arise from water that is too cold.
For the elderly, their bodies are less able to tolerate large changes in temperature and are more susceptible to damage in both hot and cold temperatures. Water that is too cold or too hot is not only uncomfortable for the elderly but also detrimental to their health.
2. From 25 ° C to 28 ° C (cool water)
This is the standard temperature for swimming pools that are held in competitions according to the FINA Law. At this temperature range, swimming performance is maximized due to their maximum oxygen consumption and bodily regulatory functions reaching their upper limit.
When the temperature is above this range, the athlete’s performance is reduced as they will use more energy to regulate their warming body temperature. This is also the temperature range where people are comfortable for playing, entertaining, and exercising underwater.
3. From 20 ° C to below 25 ° C (freezing cold water)
There is marked vasoconstriction, organ dysfunction occurs, swimming effort and swimming performance are reduced, and immersion in water will become difficult due to hypothermia.
4. Below 20 ° C (extremely cold water)
Humans come into contact with water at this temperature usually by an accident in the water. Hayward et al suggest that, at temperatures below 20 ° C, people who fall into the water must stay completely still instead of trying to swim, unless they are very close to shore, as swimming increases heat loss through the skin, leading to an earlier loss of body heat, which is life-threatening.
In general, in countries, the most common temperature for a public swimming pool used for recreation and exercise is between 26 ° C – 28 ° C. This temperature is healthy and is the best water temperature for the average swimmer. This is the temperature that makes the swimmer feel cool, when jumping into the water, it will shiver a little, but swimming a few laps feels comfortable and relaxing.
However, beyond how comfortable it is to swim in cold water, you will have the added health benefits of less anticipation. Swimming in cold water strengthens your immune system (you are less likely to get sick with wind-like diseases), increases endorphins (you will feel energized), increases blood circulation (helps you get rid of impurities faster), burn more calories (can help you lose weight), reduce stress and… increase your libido! (soaking in cold water can increase your testosterone and estrogen). For these benefits, try to discover and experience for yourself.
