This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Cabin pressure equals roughly 1,800-2,400 m of altitude, and almost every in-flight complaint follows from that or from sitting still: ear and sinus pain, dry eyes and skin, ankle swelling, clot risk by flight length, why alcohol hits harder, flying with a cold, flying after surgery or after diving, the airline cut-off week in pregnancy, and the cosmic-radiation dose of one flight as an honest number. One page per question, ~25 of them, each with the guideline behind it and a "see a clinician" line.
Fear of flying gets its own page: what turbulence is, the real numbers, and which techniques have trials.
How to use it
Use What a flight does to the body to compare stable place facts and official facilities. Live opening, access and disruption information should always be confirmed with the operator before travel.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
Search vocabulary in four languages
Terminology changes across borders. These are example phrases people use for the same subject in Estonian, Finnish, Russian and English; they are included as a practical vocabulary aid, not as hidden keywords.
| Language | Example phrase |
|---|---|
| Estonian | kõrvavalu lennukis mida teha |
| Finnish | lentäminen flunssassa |
| Russian | отёк ног в самолёте |
| English | how long after diving can I fly |
Evidence and provenance
The evidence map below records the primary, official or openly licensed material chosen for this guide. It is deliberately visible so a reader can tell the difference between a rule published by an authority, a measured dataset and an editorial explanation.
Source: WHO WRIGHT project reports on travel and venous thromboembolism (public), RCOG air-travel-in-pregnancy paper (public), DAN/UHMS flying-after-diving guidance (published), ICRP/EURADOS dose rates for the radiation figure (computed, cited). YMYL: clinician reviewer. · checked 2026-09-09
Source names are preserved even where an authority changes its web address. No figure is added to this launch page unless it is already present in the cited source description or can be computed from a named dataset.
