Humidity is the measure of the level of moisture vapor suspended in the air around you. The ideal relative humidity for health and comfort is somewhere between 30-50% humidity, according to the Mayo Clinic. This means that the air holds between 30-50% of the maximum amount of moisture it can contain.

Our perspiration evaporates to regulate our body temperature and dissipate internal heat. (relative humidity) due to a lack or fault of humidity control and the body is unable to evaporate the perspiration we generate to dissipate our body heat. …
Why is humidity control important?
Scientific evidence shows that keeping air relative humidity between 40 and 60% has significant benefits on human health. This humidity range is ideal to ensure the effectiveness of our immune defences and at the same time minimise the spread of viruses in the air.
What is ideal humidity for bedroom?

Any area with high humidity is susceptible to black mold problems. A relative humidity greater than 55 percent is enough to support the growth of black mold. Black mold thrives on moisture. Household problems such as water and pipe leaks cause water intrusion and an environment perfect for black mold to grow.
