Meteorologically, the daily maximum temperature of 35 ℃ is generally taken as the standard of high temperature. "High temperature heat wave" usually refers to the high temperature weather that lasts more than 35 ℃ for several days. High temperature is also a common meteorological disaster. In China, except for the Northeast and Qinghai Tibet Plateau, where there is little or no high temperature weather, other regions will experience high temperature weather to varying degrees. The high temperature has a certain impact on people's daily life, health and national economy, but it will also bring business opportunities to some manufacturers and businesses that produce and sell heatstroke prevention products and equipment.
