The principles of preventive medicine have remained practically the same for centuries. The idea behind those guidelines is that individuals, barring birth defects or misfortune, should stay healthy if they lead a balanced life. Sickness is an exceptional status arising from wrong behaviour or from wounds received in combat or by accident.
In Antiquity, Hippocrates formulated the precepts that a man should follow in order to maintain a good condition. In the Middle Ages, Maimonides compiled and commented Hippocrates' writings, confirming their effectiveness. Here is a summary of those principles:
- Ensure proper rest everyday at least for eight hours.
- The ideal sleeping time is between sunset and dawn.
- A man should not eat more than he strictly needs.
- Foods that are difficult to digest should be avoided.
- The most healthy drinks are water and wine.
- Bowels evacuation should take place at least once a day.
- Fruits, legumes, and nuts should be eaten regularly.
