Swimming has many benefits, and losing weight is just one of them. Losing weight is also faster. It only takes one hour every day. Because the body is directly immersed in water when swimming, water not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, so it consumes a lot of heat. Like a boiled egg, the cooling rate in air is far less than that in cold water. Experiments show that the heat consumed by a person running in a standard swimming pool for 20 minutes is equivalent to running at the same speed 1 hour on land, and the heat consumed by staying in water with 100 minutes is as high as 100 kcal, which is equivalent to being in air with the same temperature. It can be seen that water sports make many people who want to lose weight get twice the result with half the effort, so swimming is one of the most effective fitness exercises. I hope the landlord can lose weight successfully by swimming.
