American Football players and wrestlers have died because of this foolish practice. Use sweet cool drinks. Studies show athletes drink more water when it is cool and sweetened. Thirst is not always a good indicator of low body water. If an athlete drinks more water than needed they will simply pass this water quickly in the urine.
Some athletes lose more salt in their sweat and urine than others.
If salt losses are not made up with an electrolyte drink, the athlete will drink less water than they need. They will remain dehydrated even when they drink all the water they want.
