But do humidifiers help with sleep?

Humidifiers are known to create a warm environment so you can have a comfortable sleep throughout the night.

However, where the right humidity can elevate your sleeping experience, the wrong can yield numerous health issues.

What is a Humidifier and How Does it Work?

The concept of a humidifier is as simple as it sounds: add moisture to the air. Generally, you get to have two types of humidifiers, warm and cool mist.

The cool mist uses evaporation or ultrasonic. The warm mist humidifiers use the steam from boiled water to add humidity to the room.
