Dangers of lack of sleep

In Switzerland alone some 4.5 million boxes of sleeping pills and 2.8 million of tranquilizers are sold each year. In France, it’s 134 million boxes of sleeping pills or tranquilizers.

These figures show that sleeping difficulties are a real health and social problem. Tiredness and lack of sleep are not only unpleasant in themselves; they entail the risk of adverse effects and dangers, especially for the young.
