Medical Advice
When you exercise, particularly in cooler weather, the thirst mechanism becomes suppressed, and it often requires conscious effort to drink enough. On a typical day hike, you will lose four liters of water (about one gallon), more than you probably drink. Most hikers load up on water (and calories) before they head out, perhaps by drinking a liter of water with breakfast, and they hydrate again when they get done. You should still drink two to three liters of water during the day hike. A caution: don't drink too much water at once. You can not absorb it that fast, and it will go right through you.
Along with water, your body also needs electrolytes. Your body fluids contain minerals such as sodium, potassium, calcium, and others, which are responsible for muscles contracting and nerves working. So called "sports drinks" help replace electrolytes, as do certain foods such as bananas.
