Introduction
Under normal circumstances, it may take several days after heatstroke to return to work, depending on the severity of the heatstroke. Individuals with mild heatstroke usually recover and can return to work within 1-2 days; those with severe heatstroke require a longer recovery period, possibly around 7 days. To promote recovery after heatstroke, it is recommended to ensure adequate sleep during the rest period, replenish fluids and electrolytes, and maintain a light, easily digestible diet.

     In general, it takes several days after heatstroke before one can return to work, depending on the severity of the heatstroke. Mild heatstroke usually allows a return to work within 1-2 days; however, severe cases require a longer recovery period, possibly around 7 days. Detailed analysis is as follows:

     If the heatstroke is mild, with symptoms such as dizziness, fatigue, and thirst, the body can recover relatively quickly after timely cooling, hydration, and rest. Usually, discomfort symptoms can be relieved within 1-2 days, at which time one can return to work. However, care should be taken to avoid immediately engaging in high-temperature or high-intensity work.

     In cases of severe heatstroke, symptoms such as high fever, absence of sweating, and impaired consciousness may appear. Even after treatment, the body requires a longer time to recover. Since various organs may have been affected, returning to work too early may cause the condition to recur or worsen. Therefore, adequate rest is necessary, and work should only be resumed once all bodily functions have stabilized. This process may take about 7 days.

     To promote recovery after heatstroke, it is recommended to ensure adequate sleep during the rest period, drink plenty of fluids and electrolytes, and maintain a light and easily digestible diet.
