What are the methods for falling asleep quickly?
Methods to fall asleep quickly generally involve creating a suitable sleep environment, performing progressive physical relaxation, adjusting pre-sleep behavioral habits, practicing breathing regulation techniques, and establishing a regular sleep-wake rhythm. Specific details are as follows:

1. Create a suitable sleep environment: Adjust bedroom lighting to soft and dim levels using blackout curtains or a night light. Maintain room temperature between 18–22°C. Use earplugs to reduce noise disturbances, and choose a mattress and pillow with moderate firmness to ensure physical comfort and minimize interference with falling asleep.
2. Perform progressive muscle relaxation: Begin from the feet, tensing each muscle group for 5 seconds, then releasing. Gradually move upward through the legs, abdomen, chest, arms, and head. Focus on the sensation of muscle tension and release to relieve physical tension and anxiety, preparing the body for sleep.
3. Adjust pre-sleep behaviors: Avoid electronic devices one hour before bedtime to reduce exposure to blue light. Instead, engage in relaxing activities such as reading a printed book, listening to soothing music, or doing gentle stretching. Avoid caffeine-containing drinks like coffee or strong tea, vigorous exercise, or intense mental activity before bed.
4. Practice breathing regulation techniques: Lie flat on your back with hands at your sides. Inhale slowly through your nose for 4 seconds, hold your breath for 2 seconds, then exhale gently through your mouth for 6 seconds. Repeat this cycle 5–10 times to slow your breathing rate, lower heart rate, and reduce sympathetic nervous system activation.
5. Establish a consistent sleep schedule: Go to bed and wake up at the same time every day, even on weekends, to maintain your body's biological clock. Avoid long daytime naps (limit to 20–30 minutes) to strengthen your body’s natural sleep-wake rhythm.
If you continue to experience persistent difficulty falling asleep (taking more than 30 minutes) or poor sleep quality despite trying these methods, seek timely consultation with a sleep medicine specialist or a mental health professional.
