Partial or complete inability to sleep has become global health problem. A recent research by Centre For Disease Control And Prevention (CDC) found that over 14% of adults have trouble falling asleep most days, according to a 2020and about 30% of adults have symptoms of insomnia. Now, there could be a wide ranging of reasons behind this like stuffed room, city noise etc. In a similar way, there could be multiple sleep noises that could end ones over night battles. What Is Sleep Noise?Sleep noise typically refers to sounds that people use or encounter while sleeping. Experts analyze these sounds based on their frequency distribution across the spectrum, often referring to their 'timbre' or 'sonic color' to describe the unique qualities of different sounds. Based on this classification, the big three in sleep sounds are white noise, brown noise, and pink noise, but there are many other noise types, including purple noise, gray noise, and even black noise aka silence. Effect Of Different Sleep SoundsWhite noise creates a steady, even sound that can block out disturbances like traffic or snoring, but may feel harsh for some. Meanwhile, brown noise has deeper tones, similar to thunder or ocean waves, and is often calming, while pink noise offers a gentler, rain-like sound that promotes relaxation and has been linked to improved sleep, especially in older adults. Purple noise emphasizes higher frequencies and is not ideal for sleep, though it can aid in tinnitus treatment, and gray noise balances both high and low frequencies, often used in meditation for a soothing effect.Which Is The Best Sleep Noise?Unfortunately, there’s no one-size-fits-all answer. Finding the right sleep sound is a bit like finding the right type of pajamas. And while research on the sleep benefits of different noise types is limited, it is definitely growing. However, there are multiple evidence that indicate that white noise has been the go-to among sleepers for falling asleep quickly. A study published in Sleep Medicine in 2021 involving individuals living in a high noise environment in New York City found that white noise helps lessen the effects of environmental noise on sleep, improving overall sleep quality.Your sleep depends upon your body's circadian rhythm. This natural rhythm tells you when to sleep, wake up, and stay alert. Circadian rhythm disorders, also known as circadian rhythm sleep-wake disorders, occur when this natural cycle is disrupted, affecting how well you sleep and function while awake. This article will explain what circadian rhythm disorders are, the different types, and how they can affect your life. Common circadian rhythm disorders include: 1. Jet Lag Disorder: A temporary sleep disorder that occurs when traveling across multiple time zones, disrupting the body’s internal clock and causing fatigue and insomnia.2. Shift Work Sleep Disorder: A condition affecting people who work irregular hours or night shifts, leading to sleep disturbances and fatigue due to misalignment between work schedules and the body’s natural circadian rhythm.3. Delayed Sleep-Wake Phase Disorder: A sleep disorder where an individual's sleep cycle is delayed, causing difficulty falling asleep at a conventional time and waking up late, often leading to insomnia or daytime fatigue.4. Advanced Sleep-Wake Phase Disorder: A condition where individuals fall asleep and wake up significantly earlier than desired, often causing early morning insomnia and difficulty maintaining a social or work schedule.5. Irregular Sleep-Wake Rhythm Disorder: A sleep disorder characterized by fragmented sleep patterns with no clear sleep-wake cycle, often leading to insomnia and daytime sleepiness.6. Non-24-Hour Sleep-Wake Rhythm Disorder: A circadian rhythm disorder where the sleep-wake cycle does not align with a 24-hour day, leading to progressively shifting sleep patterns and difficulties in maintaining a regular sleep schedule.
