The Science Behind Kello


Let’s take a step back from Kello’s launch September 20th to look at the science that is behind Kello.

We like to think of ourselves as a sleep revolution device that uses scientifically-proven techniques to tune your body clock to get to sleep fast, snooze less, wake up earlier and prepare & recover from jet lag.

To achieve that, we analyzed hundreds of studies on sleep, on waking up, on the body clock. Here is a summary of the most important research that we based Kello features on.

… on the problem of sleep.

  • According to the Institute of Medicine, between 50 million and 70 million Americans suffer from sleep disorders or sleep deprivation. (SOURCE)

  • In 2015, the CDC declared chronic sleep disorders a ‘public health problem’. (SOURCE)


… on the abuse of sleeping pills

  • According to the Centers for Disease Control and Prevention, at least 8.6 million Americans take prescription sleeping pills to catch some zzzs. (SOURCE)


… on why regular bedtimes means better sleep

  • According to the National Sleep Foundation, keeping a regular wake-up time will train your body clock and will make it a lot easier to wake up. (SOURCE / SOURCE)


… on why gradually adjusting your bedtime helps you wake up earlier

  • According to the National Sleep Foundation, waking up in small increments means more chance to achieve waking up earlier. Gradually changing your habit will also make it easier for your body clock to adjust. (SOURCE)
  • According to the National Sleep Foundation, spending a few days at each increment will give time for your body to learn the new habit. (SOURCE)


… on why snoozing is a bad thing

  • According to a study published in the Journal of Sleep, waking up, hitting the snooze button and drifting back to sleep is called fragmented sleep. Fragmented sleep has been proven to be not restorative. (SOURCE)
  • According to a study published in the Journal of Sleep Research, falling back asleep after snoozing starts a new cycle and thus increases sleep inertia. It makes it even harder to wake up the 2nd time the alarm goes off. (SOURCE)
  • According to a study published in SLEEP, the official journal of the American Sleep Disorders Association, snoozing throws your body's natural clock off its natural rhythm, which causes you to feel less refreshed in the morning. (SOURCE)


… on why sleep is an investment

  • According to a study published in SLEEP, the official journal of the American Sleep Disorders Association, sleep time has been proven to be better use of time than the additional wakefulness earned through sleep deprivation. (SOURCE)
  • According to a fascinating paper by economists Matthew Gibson and Jeffrey Shrader, sleep is a crucial determinant of productivity. In fact, it rivals both ability and human capital in importance. (SOURCE)


… on how preparing and recovering from jet lag

  • Tailored sleep/eat schedule, critically time exposure to light before and after departure help minimising the effect of jet-lag. (SOURCE / SOURCE


… on why your smartphone is “kryptonite”

  • Numerous studies suggest that one should be wary of screens before going to bed. Light is one of the factor but keeping your mind engaged can trick your brain into thinking that it needs to stay awake.
  • Bedtime mobile phone use and sleep in adults (SOURCE)
  • Light-Emitting E-Readers Before Bedtime Can Adversely Impact Sleep (SOURCE)


… on how to get to sleep fast

  • Difficulties in getting to sleep is most of the time a problem of your brain being unable to stop being awake. (SOURCE)
  • Breathing exercises can help concentrate your thoughts and reduce heart rate to the best rhythm for sleep  (SOURCE)
