How behaviour affects water requirements
Be still.
The quieter you become,
the more you can hear. Ram Daas
Choosing when and where to walk under particular weather conditions can make a major difference to the amount of water needed by the human body. Water requirements increase dramatically as temperature and workload goes up. So selecting to walk in cooler conditions means less water loss via sweat and makes for a more enjoyable trip.
Choosing the time of day to walk can turn and exhausting mountain scramble, into a pleasant stroll up a hill. Select a route that tackles steep, exposed sections first or last in the day. During the heat of the day, find a shady lunch spot to rest and relax.
Wear light and loose clothing, nothing that sticks or irritates the skin. Select quick dry materials that still insulate when wet. Use sun protection and stop to re-apply sunscreen during the walk.
Last, and most importantly, slow down! Going as fast as possible not only exhausts the group, but it means they have less energy and incentive to enjoy their beautiful natural surroundings. People go to natural places for different reasons, but often it’s for many more reasons that getting from A to B: the journey is every bit as enjoyable as the end point, and slowing down allows more time to get to know the people in the group and relax.
