Sunbathing, hot baths and air conditioning cannot kill the neo-coronavirus. Under the condition of 56℃, it takes at least 30 minutes to kill the new coronavirus, but the body temperature of human is relatively constant, so taking a hot bath can’t raise the body temperature, which can’t destroy the virus. And people can’t take a bath in 56℃ water for half an hour, so a hot bath can’t kill the new coronavirus. Air conditioning can be adjusted to a maximum of 30 ℃, if you want to make the room temperature rise through the air conditioning, but also can not achieve the effect of killing the virus. New coronavirus is sensitive to ultraviolet light and heat, although the sunlight contains part of the ultraviolet light and heat, but the sun exposure does not reach the conditions to kill the new coronavirus, so the sun can not kill the new coronavirus.
