2. Drinking Too Much Water Too Quickly
While staying hydrated is important, drinking excessive amounts of water in a short time can be dangerous in rare cases.
Overhydration may dilute sodium levels in the blood, leading to a condition called hyponatremia. Symptoms may include:
- Nausea
- Confusion
- Headache
- Muscle weakness
This is more likely to happen during endurance sports or extreme water intake challenges. (cdc.gov)
