It's a rare individual that needs to increase his sodium intake -- after all, most Americans consume way more than the 1,500- to 2,300-milligram maximum a day. However, certain people -- such as athletes who sweat a lot -- might experience a condition known as hyponatremia, or low levels of sodium in the blood.
Skiing has a history of almost five millennia. Although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced as early as 600 BC in what is now China. The word ski is one of a handful of words Norway has exported to the international community.
The FIS recognized freestyle skiing in 1980 and organized a World Cup for the sport that year. Other sports that have gained FIS recognition include speed skiing, grass skiing (skiing on grass, using a type of skates instead of skis), and telemark (a type of downhill skiing in which the skierâs heel is not bound to the ski, as in cross-country skiing).
