When is it suitable for swimming? winter swimming

The choice of winter swimming time varies from person to person, according to personal life, exercise habits and working conditions. Because the weather is cold in winter, swimming at noon is the most suitable. It's sunny and the temperature is relatively high at this time. For working enthusiasts, it is more convenient to take a winter swim during lunch break. It should be noted that winter swimming after meals should not be too intense, so as not to affect digestion.

The advantages of winter swimming in the morning are fresh air, slow waves, and high content of negative oxygen ions on the river bank and seaside. The disadvantages are cold temperature, insufficient sunshine and the lowest water temperature in a day. Winter swimming at night is prone to accidents due to insufficient light, so be especially careful.

Repeated emission should be above 10℃

Repeated launching refers to the method of swimming in stages and launching many times in winter swimming. This swimming method can use cold water to stimulate repeatedly, and combine cold water bath and air bath closely. It is worth noting that when the water temperature and air temperature are above 10 degrees Celsius, this method can achieve a good exercise effect, such as swimming 50 to 100 meters each time and taking a rest ashore for 3 to 5 minutes. However, when the water temperature is 5 degrees Celsius and the temperature is below zero degrees Celsius, excessive cold stimulation and heat dissipation will occur in water and land, which is not conducive to the health and safety of winter swimmers.

Exercise before meals is the best.

Some winter swimmers think that swimming after eating is more energetic and has more calories. Actually, this is unscientific. Digestive organs are very sensitive to temperature. Thermal stimulation can excite digestive organs, while cold stimulation can inhibit digestive organs. Winter swimming immediately after meals affects digestion and absorption, which is easy to cause digestive system diseases such as acute gastritis. In winter swimming before meals, there is no new fatty acid in fat cells, so it is easier to "mobilize" them and convert them into heat for consumption through exercise, with the best effect.
