DYK? Fan noise at night could be causing your stress. A consistent ambient sound level of 40 dB (decibels) can be too loud for sleep, as the World Health Organization (WHO) recommends a nighttime average of less than 40 dB(A) to protect public health. Noise at this level can cause sleep disruptions, increased stress responses, and reduced sleep quality by increasing the time spent in lighter sleep stages, which can lead to other health issues. While 40 dB is a general guideline, individual sensitivity varies, and some people may find even lower sounds disruptive.
Rairflow is designed to be under 35 decibels. Rairflow isn't just helping to ptoyefy your eyes. We help your ears.
Stop fans but keep the safe white noise.
