Should I stop my regular medicines?

No — take them as usual unless your prescribing doctor specifically advises otherwise for the test.

Can I sleep with the AC or fan on?

Yes. Sleep as you normally would; a representative night gives the most useful result.

How to prepare for a home sleep test

Last updated: 2026-09-06

Quick answer

To prepare for a home sleep test, keep your usual bedtime and routine, avoid alcohol, caffeine and daytime naps that day, remove nail polish from at least one finger (for the oxygen sensor), and take your regular medicines unless your doctor says otherwise. The goal is a normal, representative night's sleep.

The evening before

Avoid alcohol and heavy sedatives that night unless your doctor has advised you to continue them, and skip caffeine in the afternoon and evening. Don't nap during the day, so you are naturally sleepy at your usual bedtime.

Small practical steps

Remove nail polish or artificial nails from at least one finger so the oxygen sensor reads properly. Shower before setup (you won't want to afterwards), and wear comfortable, loose night clothes.

On the night

Keep to your normal sleeping position and routine as much as possible — the aim is a representative night, not a perfect one. Take your regular prescription medicines as usual unless told otherwise.
