A situation like this would not cause mutations, because the factors which cause mutations, are two:
- Certain chemical substances (such as caffeine, formaldehyde, aromatic hydrocarbons).
- Radiation (such as X rays, Gamma rays, sun's UltraViolet light).

However, mutations don't always cause disease. As a matter of fact, most mutations happen automatically and are actually beneficial for evolution.
