Waking up at 3-4 am: “The Hour of the Soul” or neuroscience?

disrupts REM sleep and interrupts the sleep cycle. Sleep cycles occur in 90-minute cycles. At 3-4 AM, you’re in the last cycle, so any small noise can wake you up. Is this a “clear sign of something spiritual”? Not scientifically. Traditional Chinese medicine says “3-5 AM = lungs,” but that’s metaphysics, not medicine. Scientifically: Frequent nighttime awakenings are called Insomnia with Sleep Maintenance Difficulty. If they occur 3 nights a week for 3 months, you should see a sleep specialist. What should you do if you always wake up at 3-4 AM? Regulate your dinner: Eat protein and healthy fats 3 hours before bedtime. A boiled egg or some nuts will stabilize your blood sugar. Reduce caffeine: Cut it out after 2 PM. Cool the room: 18-20°C is ideal. High temperatures disrupt sleep. Keep a pen and paper handy: If you wake up with your mind racing, write down your thoughts in a notebook. Writing calms the brain. In short: The picture is meant to be scary. But the truth is simpler: your body is trying to wake you up. The problem isn’t the time; it’s stress, diet, or sleep quality. Does this happen to you often? Are you able to fall back asleep afterward?
