Sleep 101 Resources

Here we bring you the basics, the fundamentals, and the science. We’ll help you understand how and why sleep works, so you’re armed with the tools you need to create healthy sleep habits.

We’re examining different aspects of sleep from all angles, to bring you research-backed explanations—from the basics of the sleep cycle and circadian rhythm, all the way to the science behind lucid dreaming. No matter the sleep question, we look for the answers you need to stay informed.

Sleep is essential to well-being and health. We spend a lot of time sleeping, and for good reason. Our bodies require sleep in order to perform important tasks that they can’t while we’re awake. Things like tissue repair and growth, cognitive recovery, immune system boosting and even creative problem solving happen when we sleep, among countless other processes researchers and scientists are continuously uncovering.

Using ever-improving technology, scientists are piecing together a greater understanding of what goes on while we sleep with every passing year. We’ll help translate their work into simple, but thorough insights into the basics of sleep. Maybe you want to understand more about the sleep cycle. Perhaps you’re interested in why we dream. Most importantly, you may want to dig deep into the science of sleeping styles before you decide on which mattress will suit you best.

The Sleep Cycle and Circadian System

The rhythms of sleep, our sleep cycles, are created by the circadian system to organize the activities of our body and minds during the night.

As a bonus, we’ll explain the crazy-annoying phenomenon of jetlag!

The Science of Sleep Disorders

Sleep disorders have the potential to upend the lives of those who suffer from them. Luckily, most sleep disorders can be made more manageable with the right understanding and treatment strategies. We’ll equip you with the basics you need to get a handle on what’s behind these impediments to a good night’s sleep.

Diet, Exercise, and Sleep

Our lifestyle and our sleeping habits are deeply intertwined. What we eat and drink, and what we do with our bodies during the day can have a massive impact on how we sleep. Sleep quality also has a dramatic affect on how we live our day-to-day lives. Read all about the science that links sleep and lifestyle together.
