The perfect climate for a good night’s sleep

Ever woke up with a dry mouth and a scratchy throat? Chances are the humidity levels in your bedroom dropped below the internationally accepted threshold for a healthy indoor climate. But what is that threshold, exactly? And how do you create the perfect climate for a good night’s sleep?

Why does humidity matter?

Humidity refers to the concentration of water vapor in the air. The level of humidity in your home can influence your personal health in a number of ways. Excessively high humidity, for example, is associated with higher concentrations of allergens, whereas exposure to excessively low humidity can cause health problems such as dry skin, itchy eyes, and a sore throat. Maintaining healthy humidity levels is essential to making your bedroom a comfortable place to be and to ensuring a healthy, refreshing sleep cycle.


What is a healthy humidity level?

Humidity levels are usually measured in relative humidity, which is the ratio of water vapor in the air to the amount of vapor that can exist in the air at a given temperature. The best relative humidity for sleeping has been debated, but most studies agree that the best indoor relative humidity falls between 40 and 60%. If you tend to wake up with a scratchy throat and dry eyes, chances are the relative humidity levels in your bedroom have dropped well below the 40% threshold.


How can I ensure the perfect climate?

Ensuring a perfect indoor climate can be challenging. In climates with excessively high humidity levels, it can be a good idea to install an air conditioning system with a built-in dehumidifier. These systems automatically detect values above your preferred humidity level (usually starting at 60% RH) and extract moisture from the air to reach healthy humidity levels.

For excessively low humidity levels, installing an air purifier with an integrated humidifier can help to achieve a healthier, more comfortable indoor climate. The Daikin humidifying air purifier, for example, infuses moisture into the air when relative humidity drops below your preferred level (usually starting at 40% RH) to maintain a healthy humidity level. Moreover, Daikin air purifiers minimize asthma and allergy symptoms by removing dust particles and pollen from the air, and the Streamer Technology keeps the air healthy and fresh by breaking down allergens, eliminating bacteria, and removing bothersome odors. This purifying component sets humidifying air purifiers apart from traditional humidifiers, as traditional humidifiers tend to capture contaminants instead of eliminating them, allowing them to still replicate and potentially cause diseases. And as for noise? The Daikin air purifier with built-in humidifier is extra quiet thanks to an innovative new setup and a cutting-edge silent mode, making it one of the most silent air purifier ranges on the European market. The perfect solution for a good night’s sleep, all while keeping you healthy, fresh, and comfortable throughout.



In order to ensure a healthy indoor climate and optimal humidity levels for sleeping, make sure the thermostat in your bedroom is at the right setting. Experts agree that the ideal temperature for sleep is about 18 degrees Celsius.
