What should my roommate do if he always shakes the bed?

Talk to your roommate directly, adjust the position of the bed and use noise-reducing earplugs.

1. Talk to your roommate directly. Let your roommate know that your roommate's behavior interferes with your sleep, and ask your roommate to keep quiet or avoid strenuous exercise while sleeping.

2. Adjust the position of the bed. If you can, you can move the beds away from each other to reduce the influence of roommates shaking the beds.

3. Use noise-reducing earplugs. Noise-reducing earplugs can help you isolate external noise effectively, so as to obtain good sleep quality.
