It can be unhealthy for some people, but it depends on ventilation, cleaning habits, and anyone’s sensitivity to odors, dust, and allergens. A litter box can release ammonia odor from urine, track fine litter dust, and spread small particles on nearby surfaces. In a bedroom—where people spend long, uninterrupted hours—those irritants can feel more intense than in a larger, well-ventilated space.
The biggest concern is air quality. If you notice persistent odor, stinging eyes, coughing, headaches, or worsened asthma/allergies, the litter box location may be contributing. People with respiratory conditions, small children, and pregnant individuals may want to be extra cautious and keep litter areas out of the sleeping space when possible.
Sleeping in the same room is more likely to be unhealthy if the box isn’t scooped daily, the room has limited airflow, you use very dusty litter, or your cat has frequent accidents or diarrhea. Multiple cats using one box can also increase odor and ammonia buildup faster.
If you can’t relocate the box, focus on containment and airflow: scoop at least once daily (twice is better), fully change litter on a schedule that matches your litter type, and keep the area dry. Use a low-dust, unscented litter to reduce airborne irritants. Place the box as far from the bed as possible, and add ventilation (a cracked window or an air purifier with a HEPA filter). A covered setup can also help reduce tracking and visual clutter.

Scoop daily, use an unscented clumping litter, and wipe the box edges regularly. Improve airflow and consider a HEPA air purifier to help with both odor and dust.
