During this period it is normal to feel a bit apathetic, especially if the relative humidity is high. Tepid showers are more cooling than hot or cold ones. Large hats do not cool you down, but do prevent sunburn. Remember that, especially in the highlands, there can be a large and sudden drop in temperature between sun and shade and between night and day, so dress accordingly. Warm jackets or woollens are essential after dark at high altitude.
Loose cotton is still the best material when the weather is hot.
Insects These are mostly more of a nuisance than a serious hazard and if you try, you can prevent yourself entirely from being bitten. Some, such as mosquitoes are, of course, carriers of potentially serious diseases, so it is sensible to avoid being bitten as much as possible. Sleep off the ground and use a mosquito net or some kind of insecticide. Preparations containing pyrethrum or synthetic pyrethroids are safe. Mosquito coils release insecticide as they burn slowly.
