Generally speaking, most species of reptile have not evolved to live in mild climates like the kind we have in the UK, which is why it is essential that as a reptile owner you do everything possible to replicate their natural habitat. Monitoring and controlling your vivarium's humidity is an essential part of reptile care, as ambient heat and moisture is essential to the skin-shedding process of most reptile species.
Depending on what reptile species your pet is, ensuring that the correct levels of humidity are sustained is imperative as their circulatory and respiratory systems have developed in such a way that the efficient transference of oxygen is heavily dependent on the moisture in the air. Some species, on the other hand, require very little humidity and too much can be detrimental to their health and well-being; either way, it is important that you keep an eye on it.
