The longest anyone has ever stayed awake was eleven days and twenty-five minutes. The study was concocted by two highschool students when they needed to think of a science fair project and wanted to beat the world record at the time which was just under eleven days. One of the boys stayed awake, while the other observed. Somehow a sleep researcher got involved. The world didn’t know what would happen if someone didn’t sleep. They could possibly die. He somehow survived the time without sleep, but it wasn’t easy. His sensory and cognitive abilities were affected. It was concluded that different parts of the brain took cat naps while he was awake, which is why sometimes his senses were out of wack. With this dramatic intro in mind, let’s take a closer look at why sleep is so important. 

Why Sleep Is Important & How Sleep Affects The Brain

Sleep Affects Your Brain

As you can see from the attempts of typical high school boys, sleep is crucial to our bodies being able to function. Many people tried to break the Guinness world record after them, but Guinness stopped certifying attempts because of how dangerous the stunt is. Most people don’t value sleep as much as they should. When life gets busy, the first thing that people usually cut out is hours of sleep. I’m guilty of this as well. However, sleep should be made a priority. You think you’ll just be able to sleep in on the weekend, but sleep doesn’t work like that. You can’t make up sleep. The boy who didn’t sleep for eleven days only slept fourteen hours when he finally got to sleep. He also says that he suffers from terrible insomnia from the stunt. There’s no such thing as making up sleep, which is why you should make catching your Z’s a priority.

Our brains do a lot of work while we sleep. You may think that our brain turns off while we’re sleeping, but it’s working harder than ever. While we’re sleeping, our brain helps solidify our memories from the day. During the day, our brain had to make a lot of connection, but at night it sorts through everything to decide what’s important and what’s not. During sleep, our brains also clear out bad toxins. Basically, our brains get rid of the gunk that could be a precursor for Alzheimer’s disease. Sleep allows us to focus better which helps us be better decision-makers. Sleep affects our mental health as well. A lack of sleep can cause depression or worsen it. Many people that suffer from depression have a hard time falling asleep or get too much sleep. 

What Is White Noise? White Noise Explained

White noise is created when the sounds of all different frequencies come together. It’s called white noise because of white light, which is a combination of all the different colors, so white noise is a combination of different sounds and frequencies. Many believe that white noise is only the sound of crashing waves, rainfall, or static from a TV, but it’s so much more. It can be any noise that has the same intensity and amplitude throughout. 

White noise is usually used to cover up other noises and sounds. It may seem counterproductive, but it works very well. Just like you can’t differentiate voice in a group of one hundred people speaking, you can’t hear the voice of your next-door neighbor if you use your fan as white noise. Your brain won’t be able to pick it out anymore. White noise also has to be consistent. If someone is sleeping with a fan making noise and you turn it off, they’ll most likeley wake up. Not all white noise is created equally. A child may need something different then their parent and your partner may like something different than you. In that case, you need to find a compromise.

You’ve definitely heard about white noise before today, but you may not have known there was also pink noise and brown noise. Pink noise is different than white noise because it’s louder at its lowest frequency and softer at its highest frequency. Real-life pink noise is a light to medium rainfall. It can get pretty loud. Pink noise may be more effective for some people to get a better night’s sleep compared to white noise. It really just depends on what soothes you more and keeps you sleeping. A steady pink noise has been shown to reduce brain waves. Therefore, it increases your stable sleep. 

Unlike pink noise, brown noise isn’t quite as startling. At the low end, brown noise is strong and deep. It doesn’t contain any high-frequency sounds that are typical with white and pink noise. Many people actually enjoy listening to brown noise more than the other types of noise. It’s got a lot more bass. The changes in brown noise are random. As the frequency increases, the power decreases, which leads to very pleasant sounds that can be best described as a warm hug to your ears. Brown noise may sound very similar to white noise but it’s actually much deeper.
