From 'how do you feel' to a sleep study

Subjective → free questionnaire → wearable ($100–600) → sleep hospital.

Step 1 — Subjective. Do you feel good, wake refreshed, have energy? Then breathe.

Step 2 — Free validated questionnaires for RLS, insomnia, apnea, circadian disorders and chronotype. If you flag, go up a level.

Step 3 — Wearables / at-home tech ($100–600). Great for awareness, accountability and total sleep time.

Step 4 — Sleep hospital (polysomnography). If you have a true disease, this is where you need to get to. Take your questionnaire score to your doctor and say: here's what I scored, will you order me a sleep study? It's a pain, and it's worth it. Home sleep testing is the clear future.
