Many sugar lovers are not used to blowing air conditioners in summer, preferring to lay a cool mat to cool down, but it is best to lay a cotton sheet on the cool mat to prevent it from scratching and causing infection. Nowadays, there are mainly straw mats and bamboo mats available on the market. The main reason for this is that some of the mats are rougher and have small bamboo thorns or sharp parts that can easily pierce the skin, and sugar lovers are most afraid of skin breakdown and infection caused by trauma. It is recommended that sugar lovers use straw, rattan or linen mats. The texture of these mats is soft and the friction damage to the skin is small, and a cotton sheet can be laid on the mat to absorb sweat and avoid scratches.
