A WALK IN THE MIDDAY SUNWhen the heat is on, walkers need to be on their guard.The heat can create serious heath problems for walkers. Hot weather makes your heart pump harder, and if you’re not very fit, you start to understand why themajority of mountain rescue statistics are made up from summer walkers suffering heat attacks. Heatexhaustion is quite easy to get when you’re making great physical effort. It happens when your body can’tget enough sweat to keep you cool. Take enough water and drink it sensibly. The answer is to keep up your water intake. It’s a good idea to drink a pint of water for every 10degrees Fahrenheit every 24 hours. So, if the temperature is in the 70s, and you are doing a five- hour walk,you’ll need a minimum of around one and a half pints of water. It’s vital that you don’t wait until youdevelop a raging thirst before you stop for a drink- keep taking regular swigs from your water bottle. There are several alternatives to just water. Many walkers flavor their water with fruit juice, which makes it a lot more palatable. You could evenuse one of the isotonic drinks made for athletics, which replace the body’s salts lost through sweating.Powders such as Dioralyte, which you may have in the house as a treatment for diarrhea, will do the job justas well, as its main aim is also effective rehydration. Getting wet is one way of keeping temperatures down. Given that evaporation is your body’s cooling mechanism, you can help things along with an externalapplication of water. Soaking your hat with water is a great way to cool the head, though if the sun isbeating down, it will probably dry off almost immediately. Better still then if you can plunge into a river orthe sea fully-clothed. And if that’s not possible, then at least take off your boots and socks and paddle in acool stream.One part of your body which can suffer is your feet. Walking in the heat increases the rate at which your feet swell, which can lead to them feeling tight inyour boots. Cool water from a stream reduces any swelling and helps general foot comfort. At the sametime, you can check out your feet for signs of blisters. Extra sweating makes the skin softer and increasesthe chance of blisters forming, in the same way as when water leaks into your boots and gets to your feet.The wrong clothing can cause problems. As for what clothing you can wear, this should be lightweight and reasonably loose-fitting. Tightclothing will feel uncomfortable and may even lead to the formation of an irritating rash as “quickly heat”on your skin. The answer, if it does develop, is to try and stay cool as much as possible. Do this by eitherkeeping in the shade, or washing the affected area with cold water, but without soap. But prevention is byfar the best approach, so keep your clothing light.Your clothing acts as an important defense against the sun. It’s understandable to want to remove any extraneous clothing when it’s extremely hot, but it doesn’treally make much sense to take off T-shirts. The sun’s rays can be quite strong, and shoulders are alwaysvery sensitive to sunburn. This is the worst place to be red and sore when you are wearing a heavy rucksackon your back. Wearing shorts can also create problems for walkers, as the backs of the legs can catch thesun very easily.Always protect those parts of your body which are not covered by clothing. In fact, those days when an apparently harmless breeze is blowing can be the most deceptive. It mightnot feel so hot, so you probably won’t notice the damage being done so soon. As on every other day then, agood strong sun cream should therefore be applied to any skin which is exposed. Make the most use of thesummer, but the sun with the respect it deserves.
