Circadian Sleep Rhythm 101

Sleep, just like exercise and nutrition, is vital to our overall health and wellbeing. Getting a night of uninterrupted sleep is critical for your body to recharge for the following day’s activities. In fact, failure to get a quality night’s rest on a regular basis has been medically linked to:

  • High blood pressure
  • Heart disease
  • Loss of libido
  • Depression
  • Stroke
  • Diabetes
  • Impaired cognitive function

But what controls how often we get a night of quality, uninterrupted sleep? The time you go to sleep and wake up certainly plays a key role. However, there are other factors at play.

Body Temperature & Sleep Studies

Medical studies sponsored by the National Institute of Health and the Dutch Institute for Neuroscience have found that the key to a quality night’s sleep is understanding that your body’s core temperature changes throughout the night.

Through these studies, sleep doctors have discovered the relationship between core body temperature, the warming of your extremities, and your body’s natural inclination to enter and exit the various sleep stages. 

The findings: a good night’s rest revolves around being the right temperature at the right time.

Circadian Sleep Cycle

Sleep is regulated by two body systems – Sleep/wake homeostasis and circadian rhythm. Sleep/wake homeostasis is our internal body system that balances sleep and wakefulness. For example, if you haven’t been getting an adequate amount of sleep lately, sleep/wake homeostasis tells your body that it is time to catch some zzz’s.

Circadian rhythm, on the other hand, regulates when the periods of wakefulness and sleepiness occur throughout the day. In other words, it is the circadian rhythm that controls when, and for how long we sleep.

How Does Circadian Rhythm Affect Sleep & Body Temperature?

Circadian rhythm not only affects our natural sleep cycles but also affects our body core temperature during sleep. Studies show that body core temperature tends to rise right before we wake up, helping to create feelings of alertness in the morning. In contrast, body temperature tends to decrease at night before bed, causing people to feel sleepy.

BedJet’s Circadian Sleep Technology

For the past few years, BedJet has been collaborating with sleep doctors to use insights from the sleep temperature studies to create a new, more powerful brain for BedJet v2. Using muscular bed climate control to hack into your body’s pre-programmed circadian biorhythms, BedJet v2 alters what your body thinks it should be doing while you’re in bed.

This biorhythm sleep technology takes a leap past sleep sensors that merely monitor your sleep and uses your age, sex, and body type into account to create a custom sleep temperature profile designed just for you. BedJet v2 will make hourly climate control adjustments in your bed to ensure that you get to sleep faster and stay asleep longer.

In addition, because each individual is different, the BedJet v2 is programmed to learn from you. Sensors will make adjustments to your sleep temperature on a nightly basis, taking into account any unusual changes in room temperature as well, to create the perfect temperature profile for you.

Lose the Alarm Clock & Feel More Rested

Usually, waking up naturally means you feel more rested and ready to take on the day. Instead of the harsh (and annoying) wakeup of an alarm clock, BedJet v2 alters your body’s core temperature in the morning (at a time you select). This bio-hack wake up time resets your internal clock to alert your mind and body that it’s time to start the day by activating a pre-programmed circadian reaction in your brain.
