Bedroom humidity can be a contributing factor if you have poor sleep quality and have eliminated all other obvious factors. Indeed, the ideal humidity for sleeping is between 40 and 60 %.

Check the humidity with a hygrometer
To measure the humidity in your room, use a digital hygrometer. A hygrometer can quickly tell you the exact amount of moisture in the air by calculating the relative humidity.
Many of the digital hygrometers also come with an app that allows you to store data on changes in the humidity of your room over time. A hygrometer with an app allows you to see if the physical changes you make to your environment have an impact on the humidity level in your room.
What happens if your bedroom is too damp?
During the summer, warm air holds more moisture and, as a result, the relative humidity increases. High humidity in a bedroom can make you sweat while you sleep, making you feel overheated and uncomfortable. If you wake up in the morning with damp sheets, it may be because the humidity in your bedroom is too high.
Too much humidity in the air in your home can also lead to dust mites and mould problems, which increase the risk of allergic reactions (such as sneezing or itching) and thus disturb sleep.
How can you reduce the humidity in your bedroom?
Air conditioners and dehumidifiers can remove excess moisture from the air, reducing overall humidity levels and the risk of mould. Running an air conditioner or dehumidifier in the bedroom, even if it is only a few hours before bedtime, can help bring humidity levels down to a more comfortable level and conducive to quality sleep.
Low humidity in your bedroom can affect your sleep, as the lack of moisture can cause a number of symptoms, including dry or itchy skin, irritated sinuses, nosebleeds and a scratchy throat.
What happens if your bedroom is not humid enough?
In winter, our homes can experience the opposite problem: a lack of humidity in the air. Cool air does not hold as much moisture as warm air, so the environment around us is already less humid. Add to this the constant use of heating systems to reach the ideal temperature of the house in winter, and we remove even more moisture from our indoor atmosphere.
