Chronobiology and Sleep: How teddy's Mattresses Align with the Body's Natural Rhythms

Ever found yourself lying in bed, staring at the ceiling, wondering why you just can’t seem to fall asleep? Or maybe you've felt that groggy, disoriented sensation after staying up too late binge-watching your favourite series? These common experiences are deeply tied to a fascinating field of science known as chronobiology. Chronobiology is the study of biological rhythms—natural cycles that our bodies follow over hours, days, and even seasons. While it may sound a little complicated, understand teddy is here to demystify the concept and teach you how to use it to get the best sleep of your life. 

Understanding the Circadian Rhythm 

You might have heard of your circadian rhythm before, or if not you’ve at least experienced the effects of it. The peaking of your energy levels - feeling energised in the morning and tired at night is your circadian rhythm at work. This 24-hour cycle responds primarily to light and darkness in our environment, signalling our bodies when to sleep and wake. 

We like to think of it as an internal alarm clock that not only tells you when to rise but also when to start winding down. When our sleep schedules align with our circadian rhythms, we experience better sleep quality, improved cognitive function, and enhanced mood stability. 

On the other hand, spending too many nights out late or sleeping in till noon (as enjoyable as it may be) risks circadian rhythm misalignment. This can lead to sleep disorders, reduced productivity, and even long-term health issues.

The Importance of Circadian Alignment

You might be wondering if staying aligned with your circadian rhythm is as important as we’re making it out to be. Don’t just trust us, experts at the University of California have researched the importance of circadian rhythm alignment and came back with some pretty shocking results. It turns out a lot of illnesses are caused, and exacerbated by being poorly aligned with our environment. 

This is because our body repairs itself overnight. When our internal clock tells our cells it's dusk and we go to sleep, our DNA uptake and incorporation increases dramatically. On the other hand, when our bodies are telling our cells that it’s dark outside but we ignore it and stay awake, we fail to produce the same uptake of DNA incorporation and miss out on crucial hours of rejuvenation. 

This means when you feel a runny nose coming on, aligning with your circadian rhythm can make all the difference in helping your body fight off a cold. Of course, the importance of this goes beyond sick days. In everyday life, Maintaining circadian alignment helps regulate hormone levels, supports mental clarity, and promotes emotional well-being. 

teddy's Mattress Technologies for Optimal Sleep

At teddy, we understand the crucial role of sleep in maintaining health and well-being. That's why we've developed mattress technologies designed to support and enhance your body's natural rhythms. Our mattresses incorporate features like temperature regulation and comfort customisation to ensure you get the best possible sleep.

Temperature Regulation

There’s nothing worse than waking up in the middle of the night drenched in sweat or shivering from the cold. One of the key elements of a good night's sleep is maintaining an optimal body temperature. Our body temperature naturally dips during sleep, signalling our bodies to enter a state of rest. teddy's mattresses are designed to support this natural process through advanced temperature regulation technologies. 

We use ZoneScape™ 5 Zone and Airflow Foam Technology which allows for optimal air circulation, preventing overheating. Additionally, with some options like our Idream Elite Mattress, you can customise the fabric covers. Whether you opt for the cooling sensation of our summer fabric SensICE, or our cosy Intense fabric for the cooler months, you can rest assured knowing your temperature will remain regulated throughout the year. 

Comfort and Customisation

Everyone has unique sleep preferences, and at teddy, we believe your mattress should adapt to you, not the other way around. Our mattresses offer customisable comfort options that cater to individual sleep needs. 

For example, our classic Idream Mattress comes with removable layers so you can switch your firmness between 7/10 (Medium-Firm) or 9/10 (Firm). This means you can enjoy sturdy back support or a soft, cloud-like feel all from the same mattress. Of course, we can’t forget the importance of comfort for your little ones. Our Premium teddy Junior Lux mattress offers the same customisable layers to ensure your child gets the support their growing body needs. 

Ultimately, a more comfortable bed will help you not only fall asleep faster but stay asleep for longer. Our customisable mattresses ensure that your body is properly aligned with your circadian rhythm, allowing you to wake up refreshed and rejuvenated.

Tips and Tricks 

While having the right mattress is crucial, there are also a few other additional tips and tricks to ensure you stay aligned with your natural circadian rhythm:

  1. Maintain a Consistent Sleep Schedule: We know it’s hard, but go to bed and wake up at the same time every day, even on weekends. Consistency reinforces your body's natural sleep-wake cycle and can help you fall asleep and wake up more easily.
  2. Get Plenty of Natural Light During the Day: Exposure to natural light during the day, especially in the morning, helps regulate your circadian rhythm. Spend time outside or near windows to boost your daytime light exposure.
  3. Limit Exposure to Artificial Light at Night: Minimise exposure to blue light from screens (phones, computers, TVs) at least an hour before bedtime. Consider using blue light filters on your devices or wearing blue light-blocking glasses.
  4. Optimise Your Sleep Environment: Make your bedroom conducive to sleep. Ensure it's cool, dark, and quiet. Use blackout curtains to block out light and a white noise machine or earplugs to minimise noise disruptions.
  5. Watch Your Diet and Caffeine Intake: Avoid heavy meals, caffeine, and alcohol close to bedtime. These can interfere with your ability to fall asleep and stay asleep. Opt for light snacks if you're hungry before bed.
  6. Stay Active During the Day: Regular physical activity can help you fall asleep faster and enjoy a deeper sleep. Aim for at least 30 minutes of moderate exercise most days, but avoid vigorous workouts close to bedtime.
  7. Avoid Long Naps During the Day: While short power naps can be beneficial, long or irregular napping during the day can negatively affect your nighttime sleep. If you need to nap, try to keep it under 30 minutes and not too close to bedtime.


Understanding and respecting your body's natural rhythms is key to achieving optimal sleep and overall wellness. By aligning your sleep schedule with your circadian rhythm, you can improve your health, cognitive function, and mood. Next time you find yourself counting sheep, ask yourself: is your mattress helping or hindering your quest for restful sleep? With teddy, you can rest assured that every night will be a step closer to perfect harmony with your body’s natural rhythm.
