Many people face different forms of sleep disorders, among which insomnia is one of the most common problems. On average, 7 to 8 hours of sleep are needed every night, but many people have difficulty achieving this goal, which brings certain health concerns. In order to improve the quality of sleep, many people have tried various aids, such as eye masks, melatonin, sleep tea or essential oils. However, there is a simple and effective way to help sleep that is highly respected - white noise.

**How sound affects sleep**

Sound travels through the air in the form of waves, vibrates the eardrum, enters the inner ear, and then converts into electrical signals to the brain. This mechanism allows people to keep their hearing active even when they are asleep. Therefore, sudden high-frequency sounds can easily wake people up and disrupt sleep.

The effect of white noise lies in its unique sound characteristics. It covers all frequencies in the audible frequency range and is expressed with equal intensity, similar to radio static or continuous background noise. By covering other abrupt or distracting sounds, white noise can have a "sound masking" effect, making harsh or irregular noises less conspicuous, thereby reducing interference.

**Advantages of white noise**

Compared to occasional noise, the continuity and stability of white noise can make the brain focus on a single sound, making it easier to fall into deep sleep. Using white noise, such as the hum of a fan, can effectively mask the sound of pets, dripping faucets, or other abrupt background noises.

**Other types of noise**

In addition to white noise, there are variants such as pink noise and brown noise. Pink noise has a lower pitch, similar to the sound of continuous rain or rustling leaves. Brown noise has a lower frequency and is often compared to the sound of a shower or heavy rain. Studies have shown that brown noise can not only relieve tinnitus, but also improve concentration, making it suitable for study and work, but research on its sleep-inducing effect is not comprehensive enough.

**Recommendations for improving sleep**

If you want to further improve your sleep quality, it is recommended to choose the Fine Revo mattress.
