I guess we’re all concerned about this. By far, the Langdale Mountain Rescue Team in the UK Lake District and the UK Ramblers Association provide the most comprehensive information available on the web. Of course not all of it is relevant to Spain. For example, we don’t expect too much hypothermia! However, a good deal of their information can be directly applied to our situation over here. Advice about drinking water is particularly helpful to walkers in a hot climate.
ADVICE ABOUT DRINKING WATER.
From the UK Ramblers Association.
In cold weather the greatest danger is hypothermia or exposure: this occurs where the body temperature is chilled to a life-threatening level, and is aggravated by wind chill. To avoid it make sure you have enough warm clothing and extra food and plenty of water.
In warm weather, the principle hazards are sunburn, windburn and dehydration. Sunhats, sun cream, and water can prevent serious sunburn or heatstroke.
Don’t underestimate the amount of water you need. Doctors recommend drinking 1.5-2 litres of water a day even for an ordinarily active lifestyle, and you will need more if you walking strenuously and/or the weather is hot. Don’t wait until you’re thirsty to drink. Still mineral or tap water is adequate: fizzy drinks are not recommended as they take longer to drink, a problem if you need to rehydrate quickly. Avoid drinking unboiled or unpurified water from streams, and when in the hills carry emergency water purification tablets.
