Staying Hydrated for Diving

A simple thing you can do is minimize the cups or plastic bottles used on a dive trip.  Most boats have paper cups and a cooler of water for their divers to use. Most don't recycle so they will end up in the garbage and land fills. Along comes a decent wind and they end up in the ocean. 

Take a water bottle with you. There are water bottles that are super insulated like the Hydro Flask that we carry that will keep your liquid cold for 24 hours.  I'm telling you they really work great. Even in the hot sun, my Hydro flask is ice cold at the end of the day. If you fill it up with ice then you can fill it on the boat as often as you drink.
