Hydrate Yourself Frequently When Walking

Whether you are in a hot climate or not, your fluid requirements will increase significantly when trekking. Losses on the breath and from sweating will serve to reduce your blood volume, resulting in your heart having to work much harder. By the time you feel thirsty you will already be dehydrated so try and drink small, frequent quantities of water throughout the day. Carry out the urine test to monitor your hydration: a pale straw color indicates that you are well hydrated, anything darker means that you need to drink more.
