Toys must be exposed to the sun, otherwise the sweat released by the human body will breed fungi. Sunlight can keep toys dry, and ultraviolet rays can also sterilize them. Sunlight will make toys more and more swollen and bigger. A week is appropriate, and the sun exposure rate is guaranteed for 2 hours every day.
Put the toy in the sun to dry and radiate ultraviolet rays, effectively eliminating the hidden mites and bacteria in the toy. At the same time, high temperature will evaporate water, making sterile bacteria in toys, so it can effectively prevent the occurrence of various diseases, such as respiratory tract infections and skin allergies, and even reduce the risk of asthma.
