Water
The natural choice for hydration is water. It hydrates better than any other liquid, both before and during work. Water tends to be less expensive and more available than any other drink. You need to drink 4-6 ounces of water for every 15-20 minutes of work. That can add up to a lot of water! Water is the best, but it only helps you if you drink it.

Hot weather causes more fatalities than any other weather-related source. Heat waves rarely are given adequate attention but in fact, they claim more lives each year than floods, hurricanes, and tornadoes combined. Heat waves are a silent killer. Heatstroke also affects both genders equally. However, because many men were exposed to heat in the workforce, the annual death rate is 2 times higher in men than in women.
