English version:    • Pro Tips to Fall Back Asleep Fast Aft...  

Today, let's talk about some simple yet practical topics. I've had friends ask me, "I can fall asleep normally between 10 and 11 PM, but after waking up around 2-3 AM, I find it very difficult to fall back asleep. Are there any methods to help me continue sleeping after waking up in the middle of the night?" Because if I don't get enough sleep, I notice I'm less energetic and my immune function declines the next day.
So, I'll share some simple methods that might be helpful to you. However, if you continue to experience issues with waking up in the middle of the night even after trying these simple methods, I recommend you consult a doctor at a hospital.
