Absolute humidity vs temperature

Each curve is a relative humidity. The same 50 % holds about 4.7 g/m³ at 10 °C, but 15 g/m³ at 30 °C. The black dot is your values.

Questions

Why is absolute humidity important for Empty Nose Syndrome?

Absolute humidity represents the actual amount of water vapor in the air, regardless of temperature. For ENS patients, maintaining a specific level of water per cubic meter (g/m³) is often more critical for nasal comfort than relative humidity percentage.

How is absolute humidity calculated?

It is calculated using the temperature and the relative humidity. The formula determines the mass of water vapor per volume of air, usually expressed in grams per cubic meter (g/m³).

What is the ideal absolute humidity for nasal comfort?

While it varies per individual, many ENS patients find relief when absolute humidity is kept above 10-12 g/m³ to prevent nasal mucosa dryness.
