Drink lots of water! It’s likely the campaign you’ll work for will provide you with complimentary bottled water, and if you’re in Texas, it’s likely you’ll canvass when the temperature is 90 degrees or higher.
Water makes up more than two-thirds of human body weight, and without water, we would die in a few days. The human brain is made up of 95% water; blood is 82% and lungs 90%. A mere 2% drop in our body’s water supply can trigger signs of dehydration: a fuzzy short-term memory is the last thing a canvasser needs.
