Understanding Electrolytes

The video explains the importance of electrolytes, which are salts that dissolve into ions and conduct electricity in water. They regulate water flow in cells and nerve impulses, crucial for body functions like heartbeat and breathing. Electrolytes also make sweat salty, helping cool the body. While sports drinks are marketed for electrolyte replenishment, most people get enough from their diet. The video concludes by inviting viewers to ask chemistry questions.
