Noisy dormitory may affect your sleep quality. To help you fall asleep faster, you can try the following methods:

1. Make a regular schedule: try to keep going to bed and getting up at the same time every day so as to adjust your biological clock.

2. Create a comfortable sleeping environment: keep the dormitory temperature moderate, avoid strong light and noise, use comfortable mattresses and pillows, and suitable bedding.

3. Reduce stimulant intake: Avoid taking caffeine, nicotine, alcohol and other stimulants before going to bed, so as not to affect the quality of sleep.

4. Relaxation: Do some relaxation activities before going to bed, such as reading, yoga, meditation or deep breathing exercises, to help the body and brain relax.

5. Restrict the use of electronic devices: Try to avoid using electronic devices such as mobile phones and computers within one hour before going to bed, because the blue light emitted by these devices may affect your sleep quality.

6. Exercise: Keep regular exercise, but avoid strenuous exercise near bedtime, because it may make you more excited.

7. If possible, communicate with your roommates more: tell them your troubles, seek their understanding and support, and create a quiet sleeping environment.

8. If the above methods can't solve the problem, you can consider contacting the dormitory administrator or the relevant department of the school to seek other solutions.
