Direct Sunlight & Daytime

Another preventive measure that workers can use to protect themselves from heat-related stress is avoiding both direct sunlight and working during peak daylight times. Direct sunlight exposure can increase outdoor air temperatures by 14° Fahrenheit, which also increases the heat index and associated risks, and the need for special precautions.

Using the heat index to establish the hottest times of the day before beginning work is a good way to plan work schedules. This will also bring attention to these added risks, and it will encourage workers and employers to avoid highly strenuous activities at these peak times.

Sunscreen is another precaution that workers can use to protect themselves from the effects of high temperatures and direct sunlight. Sunburns can occur through clothing and through cloud cover.
