It helps create saliva
Water is a main component of saliva. Saliva also includes small amounts of electrolytes, mucus, and enzymes. It’s essential for breaking down solid food and keeping your mouth healthy.
Your body generally produces enough saliva with regular fluid intake. However, your saliva production may decrease as a result of age or certain medications or therapies.
If your mouth is drier than usual and increasing your water intake isn’t helping, see your doctor.
Staying hydrated is crucial to maintaining your body temperature. Your body loses water through sweat during physical activity and in hot environments.
Your sweat keeps your body cool, but your body temperature will rise if you don’t replenish the water you lose. That’s because your body loses electrolytes and plasma when it’s dehydrated.
If you’re sweating more than usual, make sure you drink plenty of water to avoid dehydration.
