Cheers BOD for this
It seems like basics, but you would be surprised on how many people fail to take the basic precautions.
i am currently out in sub-saharan africa, and the amount of people we have to get looked at as they do not take the necessary preparations for working in highly humid environments is amazing, despite being shown the risks and given the lectures and access to supplies and equipment to kit themselves out..... most treat there working days as they would as if it is spring in the UK
if you are out in the tropical climates a basic water kit should be taken at all times (mine is currently a kattadyn hiker water purifier and a crusader mug, cooker and bottle) and remember the basics checks to avoid dehydration .....monitoring the frequency and character of urination.
If you develop a full bladder at least every 3-5 hours and the urine is only lightly coloured or colourless, chances are that dehydration is not occurring;
if urine is deeply coloured, or urination occurs only after many hours or not at all, water intake may not be adequate to maintain proper hydration.
When large amounts of water are being lost through perspiration and concurrently replaced by drinking, maintaining proper electrolyte balance becomes an issue. Drinking fluids that are hypertonic or hypotonic with respect to perspiration may have grave consequences.
if you are in the jungle then it is always good to learn how to get clean water from plants (such as bamboo) etc where water is stagnated....
i know many people probably already know this stuff.... but reiteration is some time required as a little reminder as to pack for you surroundings!
