Heavy sweating

Prolonged heat exposure, endurance exercise and prolonged physical work can increase your sweat rate. Fluid and electrolytes are commonly lost through sweat making it important to replace them to avoid dehydration.

A fever is defined as an elevated body temperature (above 98°F). This is often accompanied by increased sweating and the potential for mild dehydration. People with a fever can find they eat or drink less than normal, which may also contribute to dehydration.

Rehydration Solution for Adults

In order to prevent and relieve dehydration, adults should consume an oral rehydration solution (Hydralyte) when they are at risk of dehydration.

Hydralyte is scientifically formulated to contain the correct balance of glucose and electrolytes for rapid rehydration. The formulation is based on the World Health Organization criteria for effective rehydration. Water or sugary drinks are not as effective as Hydralyte, as they do not restore lost electrolytes (which retain the fluid).
