White noise-Rain-Deep Sleep-Relaxing (8 Hours)

Many people think that rainy days are suitable for sleeping. As long as the rain is continuous, they don’t even want to get up. Even listening to the sound of rain in the office will make them feel particularly sleepy. In fact, rainy days not only make you want to sleep, but also make you sleep more sweetly. This is scientifically justified and related to "white noise".
