Technologies for Better Sleep

Sleep Technologies

For many, falling asleep quickly or sleeping through the night is a luxury. Many of us today don’t get enough sleep, not because we don’t have time, but because we can’t sleep well. However, with the advent of science, today we can embrace many technologies for better sleep.

Sleep-related disorders have become more prevalent over the last several decades, impacting wider age group, including young adults and students The International Classification of Sleep Disorders – Third Edition (ICSD-3) by American Academy of Sleep Medicine categorizes sleep disorders into

Sleep Disorder as defined by ICSD-3

  • Insomnia
  • Sleep-Related Breathing Disorders
  • Central Disorders of Hypersomnolence
  • Circadian Rhythm Sleep-Wake Disorders
  • Parasomnias
  • Sleep-Related Movement Disorders
  • Other sleep disorders

We can already see from the classification how widespread sleep-related issues are in our modern society. There is no single solution that can solve all sleep problems. The purpose of this article is not to discuss sleep hygiene, environmental purification, lifestyle changes, meditation, diet, supplements, or severe medical treatment for conditions specified in ICSD-3. Instead, we will explore a number of self-help technologies that can help you get a better night’s sleep at home. Research has shown that many of these technologies improve sleep quality for people with non-severe conditions, and their effectiveness has been verified in several clinical studies. The technologies are based on two key principles.

Technologies for Better Sleep

Sleep Technologies

a) Sleep Inducing Technologies

The use of brainwave entrainment technologies is intended to reduce sleep latency just before, during, and after sleep. Additionally, it may be used throughout the sleep cycle to improve sleep quality, or to reduce pain that may interfere with sleep. They usually involve frequency-based solutions that calm down the mind and entrain the brainwaves to a certain “desired” state, a more targeted approach to induce sleep. In a lot of ways, this is similar to hypnotizing. Generally speaking, Brainwave Entrainment Technology refers to technologies that affect the brainwave via frequency-specific pulsing stimulation (tactile, sound, light, pulsing EMF, etc.). In most cases, the effect will manifest within a week or two, if not immediately.

b) Mental and Body Relaxation Technologies

With transcranial electric stimulation, you can achieve desired relaxation, or a balance of neuro-chemicals, whether during the day or at night. Unlike brainwave entrainment, they are less targeted and more holistic in terms of getting your body to adjust naturally. It typically takes longer for the effect to manifest and may be more subtle in general.
