The sun does not kill lice. Lice are small insects that feed on human skin, and they typically do not live on the sun itself. In fact, lice prefer relatively cool temperatures to繁殖 and thrive, indicating that the sun's heat is not a significant factor in their killing.
Instead, lice are usually killed by environmental factors such as temperature, humidity, and cleanliness. For example,高温 and humidity can accelerate the life cycle of lice, making them more susceptible to death during hot dry weather. Additionally, if the environment is not clean, lice can get caught in human skin crevices and die as a result of the environmental stressors.
Therefore, while the sun may dry the skin and cause discomfort, it does not directly kill lice. To prevent the spread of lice, it is important to keep the environment clean, avoid overcrowding, and use insect repellents to reduce the risk of contact with lice.
