Are there any measures for disease prevention which were used in early times that should be used today

Ancient peoples didn't use tobacco.
Obesity was rare.
P.S. Also before antibiotics were around, people had to rely on herbs, etc. Nowadays, if a person takes too many antibiotics, or too often, that person will become "immune" and when an antibiotic is truly needed, it might not work. Besides, many diseases are becoming resistant to antibiotics.

Native Americans have cultivated tobacco since around 4,000 years ago. They may have used it as early as 15,000 years ago.
