Rehydration

Rehydration is the process of restoring lost fluids and electrolytes in the body, often after dehydration caused by factors like illness, heat, or strenuous activity. It involves consuming fluids—such as water, oral rehydration solutions, or specific drinks—that replenish the balance of salts and minerals essential for normal body functions. Effective rehydration helps maintain blood circulation, supports organ performance, and promotes recovery. It is a vital step in managing conditions like diarrhea, vomiting, or heavy sweating to prevent complications such as fatigue, weakness, or more severe health issues.
