How can technicians safeguard against heat stress?

Staying hydrated and taking regular breaks in cool areas is essential for preventing heat stress, particularly when performing physically demanding tasks in hot environments. Hydration helps maintain the body's ability to regulate temperature through sweat, which is the primary mechanism for cooling. Regular breaks in shaded or air-conditioned areas allow the body to recover from the heat accumulation that occurs during periods of intense activity.

It's also important to note that working during the cooler hours of the day can certainly minimize exposure to heat; however, it may not entirely eliminate the risk of heat stress, especially if hydration and rest are not prioritized. Wearing extra layers of clothing can trap heat and increase the body temperature, which contributes to the risk of heat stress. Additionally, while caffeine can have some stimulating effects, it is a diuretic that may promote dehydration, which is counterproductive in the context of heat management. Therefore, the best practice among the provided options is to stay hydrated and take regular breaks in cooler areas.
