Hydration is crucial, especially during the hot Okanagan summer, as dehydration can lead to serious health issues like cramping, dizziness, and even death. Daily intake should be around 3 liters, with 2 liters coming from beverages, and it's important to drink water even before feeling thirsty, especially since alcohol can further dehydrate the body. For athletes, consuming fluids with electrolytes before and during exercise supports health, recovery, and performance, with products like BioSteel recommended for optimal hydration and recovery.
