In physically demanding jobs like construction, hydration is essential to not only worker productivity but also safety. This is especially the case when the heat index climbs above the 103°F mark.
The CDC says water will almost always help workers maintain proper hydration while working in the heat, as long as they eat regular meals to replace the salt lost through perspiration. OSHA says workers should drink at least 8 oz. of cool water every 20 minutes on shorter jobs.On hot jobs lasting longer than two hours, where prolonged sweating can lead to excessive salt loss, OSHA says electrolyte-containing beverages such as sports drinks should be considered.
