(1) Can a hot water bottle keep it warm overnight?

According to the editor's understanding, it is impossible to keep a hot water bottle for one night, and it will be useless for about two or three hours. This is due to its own characteristics. A hot water bottle is a bag made of rubber or waterproof material filled with heated liquid to keep it warm. There are two types of hot water, one is mechanical, which is heated by adding hot water; the second is an electric heating bag, which is filled with special oil and heated by an electric plug. It is understood that the heat preservation time of the hot water bottle is about 3-5 hours, and it will not be too hot for longer. It can last more than 6 hours in the bed. Salt can be used to keep the temperature of the hot water bottle longer.

Do not fill the hot water bottle full of hot water, leave a little air, and then add salt to the water. After adding salt, the depth of the water will increase, and the hot water will cool down slowly, which will achieve the effect of making the hot water bottle more heat-insulating.
