Curious about how others fall asleep as soon as their head hits the pillow? With "Deep Sleep Unlimited," you can achieve it too.


Sleep is the most effective way to relieve fatigue and recharge your energy. When you're tired and drowsy, there’s nothing more comforting than collapsing into bed, pulling the covers over yourself, and drifting off into a deep sleep—so much so that you lose track of time until dawn breaks. Who wouldn’t envy someone who can fall asleep as soon as their head hits the pillow?


However, the reality is that many people toss and turn in bed—pulling the covers up, then kicking them off again—and their phones light up over and over, yet they just can’t fall asleep. After tossing and turning through half the night, they finally glance at the clock only to see it’s already 2 a.m. Faced with the thought of having to go to work the next day, they’re suddenly consumed by anxiety. By the time they finally drag themselves out of bed the next morning, they can’t help but wish they could’ve beaten up last night’s version of themselves.

 

 

In China, 300 million people suffer from sleep disorders, with their sleep issues primarily manifesting as "difficulty falling asleep" and "shallow sleep."


1. Difficulty falling asleep


Some people can’t fall asleep due to high stress or sleep anxiety, while many others simply can’t kick the habit of scrolling through their phones before bed. A recent report titled "2021 China Youth Sleep-Time Phone Usage Report," which surveyed over 2,000 young adults, revealed that more than 80% of respondents use their phones every night before sleeping—and nearly 40% spend over an hour doing so.


Scientific research reveals that mobile phones affect sleep primarily through three key mechanisms: First, excessive phone use encroaches on your natural sleep time; second, the content on your phone triggers both physiological and psychological arousal; and third, the blue light emitted by phone screens suppresses the body’s normal production of melatonin. As melatonin is a critical regulator of the body’s circadian rhythm, its suppression can make it harder to fall asleep. In short, if you want to enjoy a good night’s rest, the first step is to put your phone down.

 

 

2. Not sleeping deeply


Although I fall asleep easily, my sleep isn’t very deep—I often wake up two or three times during the night. What can I do about this?


Sleep expert Donble Mattress, after years of research, has discovered that once a person falls asleep, their body naturally shifts and adjusts its sleeping position to find the most comfortable posture. At this stage, if the mattress is too soft and lacks adequate support, the body may sink into it, making it harder to turn over. Over time, this can lead to discomfort throughout the body.


If you struggle with shallow sleep and want to achieve "limitless deep sleep," you’ll need a mattress that makes it easy to turn over. Dongguan-based, locally trusted brand Donble Mattress—boasting 29 years of experience—has been dedicated to providing Chinese consumers with healthy, high-quality sleep. Designed specifically around Chinese sleep habits, their mattresses feature a firmer, spine-supporting design that offers excellent support, ensures a flat, spacious feel, and promotes effortless turning. This helps maintain the body’s natural spinal curvature, safeguarding your lower back health in the process.
