Based on research conducted by the National Sleep Foundation in 2011, Generation Y (born in the 1980s to the late 1990s) experienced more problems with difficulty falling asleep than the previous generation. In fact, another study by a team of experts from the University of Warwick Medical School in the United Kingdom estimated that currently there are around 150 million people in the world who experience sleep problems.
Research conducted by the American Psychological Association states that generation Y who have an age range of 18-33 years experience higher stress than the previous generation.
More than 50 percent of the study subjects reported being awake at night due to anxiety caused by various problems. Starting from examinations, the cost of continuing college, finding a job, moving to a new place, getting married, and building a family is a burden on the mind that is blocking every night and makes the brain not stop spinning.
When sleeping, humans still receive sounds that are processed in the part of the brain called the auditory cortex. A person's sensitivity to sound varies, depending on brain waves produced when we sleep. Some sounds can be captured as disturbing sounds and other sounds may be captured as a soothing voice.
However, to find out whether certain sounds are considered annoying or soothing to someone is not easy.
Why can the sound of rain help us sleep better?
Our brains interpret various types of sounds that are heard when awake or when sleeping become something dangerous or not. Some sounds like screaming or very loud alarm sounds cannot be ignored, but certain sounds such as the sound of the wind blowing or the sound of the waves can be ignored.
Sounds that have a high volume tend to be more difficult to ignore, but more important is about the character of the sound we hear whether it can stimulate our brain to activate a danger sensor so that it wakes us from sleep or not.
The sound of rain, although sometimes it sounds quite loud, is classified as a type of non-threatening sound so that the sound of rain can dampen other sounds that can keep us awake, such as the sound of vehicles passing. The characteristics of the sound of rain enter as one type white noise, which is a constant sound.
What is white noise?
White noise is a sound that can be heard with a frequency between 20 to 20,000 Hertz (Hz) and has the same amplitude and intensity. One type white noise what we can find is pure sound that sounds like a static wave of radio or television, but the type of sound is very uncomfortable to hear. Several types white noise others can be:
- Nature sounds like the sound of rain, the pounding of the waves, the sound of crickets, the sound of the wind blowing in the forest, and others.
- Engine sounds such as air conditioner or fan or clothes washing machine sound.
Most people prefer to listen to these sounds in comparison to listening white noise pure because it sounds more comfortable.
