Many people wake up during the night, especially in the early hours of the morning, and often find themselves suddenly awake, wondering why. In fact, this phenomenon is very natural, and our biological clock and body rhythms cause this to happen. The human body temperature fluctuates as the day goes on. At around 10:30 pm, the body temperature begins to drop, prompting the brain to secrete melatonin to help us prepare for sleep. As the body temperature drops further, we enter the deep sleep stage. However, between 2 and 3 am, the body temperature begins to rise again. This rise in body temperature often pulls us into a lighter sleep stage, so waking up at this time is normal.

When waking up, fluctuations in carbon dioxide (CO2) levels and changes in heart rate also contribute to this awakening. During sleep, breathing slows down and CO2 levels rise to maintain unconsciousness. But when we wake up suddenly, CO2 levels drop and heart rate increases. In order to re-enter a state conducive to sleep, we need to reduce our heart rate to less than 60 beats per minute and adjust CO2 levels.

As for how to fall back asleep, experts recommend avoiding checking the clock, as this can easily cause anxiety, and a tense mood can increase your heart rate, further affecting your sleep. Instead, you can turn the clock to a place where it is not easy to see and focus on staying calm. In addition, try non-sleep deep rest (NSDR). Even if you can't fall asleep completely, staying in a quiet, dark environment can help your body and brain recover. Studies have shown that one hour of non-sleep deep rest has the same restorative effect as 20 minutes of sleep.

Another trick to help you fall back to sleep is deep breathing. Deep breathing can effectively help regulate carbon dioxide levels and heart rate. You can try to inhale slowly for 6 seconds, hold your breath, and then exhale slowly for 8 seconds. Repeating this process will help stabilize carbon dioxide levels and lower your heart rate, helping your body relax and return to sleep.

In addition, staying quiet is key, and avoid getting up unless necessary. Getting up and moving can increase your heart rate, which will affect falling asleep again. If you can't fall asleep immediately, don't be too anxious. Stay in bed and focus on breathing exercises to help your body relax and help you fall asleep. At the same time, you can prepare a glass of room temperature water to avoid excessive wakefulness caused by cold water stimulation. Keeping indoor air flowing and avoiding high carbon dioxide concentrations can also help maintain a comfortable sleeping environment.

Many people wake up at night as part of the body's natural rhythm. Through deep breathing, non-sleeping deep rest and other methods, you can effectively help the body and brain re-enter a relaxed state and fall asleep smoothly. At the same time, creating a quiet and comfortable sleeping environment is crucial, and choosing the right mattress is one of the important factors in improving sleep quality.
