Whether the hand temperature can change color depends on the ambient temperature. If the ambient temperature (air temperature and room temperature) is very high and exceeds 31 ° C, then 25 ° C and 31 ° C are already high temperature colors. At this time, the human body temperature is also relatively hot and the hand temperature is relatively high, so 35 ° C should be selected. If the ambient temperature (air temperature and room temperature) is very low and lower than 10 ℃, your hands can't be frozen and cold, and you can't change the color of 25 ℃ thermosensitive powder, let alone higher temperature. If the ambient temperature is within 20 ℃ - 25 ℃, choose 25 ℃ thermosensitive powder. If the ambient temperature is within 24 ℃ - 30 ℃, choose 31 ℃. If the ambient temperature is within 30 ℃ - 35 ℃, choose 35 ℃
