The probability of suffering from fatigue is greatly reduced if the skier has done some preseason exercising. The type of exercise program adopted is for the individual to choose. If a person embarks on a skiing holiday feeling in good shape and relaxed, he or she can assume the exercises have been successful. Another wise precaution every skier should take is a quick warm-up without skis before the first run of the day. Anything helps, from touching the toes to running on the spot.
Weather conditions present a hazard to the skier.
It is unwise to continue to ski if snow conditions deteriorate. For example, a slippery ice crust can form over wet snow during late afternoon. No skier should continue if visibility is reduced either by fog or by snowfall. Another weather hazard skiers must be aware of is the possibility of sunburn, particularly from the rays reflected off the snow. Protective eyewear, such as shatterproof sunglasses or goggles, will protect eyes from the sun's ultraviolet rays and from injury, in case of a fall.
