Why are most of the helmets seen in yellow in daily life?

Because of the high visibility of yellow, the human eye is sensitive to yellow, which can arouse people's awareness of danger, so it is especially suitable for high-risk workplaces such as construction sites and factories. Yellow can also reflect light well and ensure the temperature of the surface of the object. On the construction site in summer, the worker's head can be protected from the sun to prevent heat stroke and other diseases. In addition, yellow is used as an international safety color, and yellow helmets are often used in earthquake rescue and rescue.
