Long-haul flights can take a toll on your body.
Here’s what to watch out for:

Deep Vein Thrombosis (DVT) risks
DVT and pulmonary embolism (PE) can be life-threatening and affect even young, healthy travellers.
Risk isn’t limited to economy class — immobility is the main culprit.
Stay hydrated, walk often, avoid sleeping pills, and wear compression stockings.
Sudden turbulence injuries
Severe turbulence incidents are rising — potentially due to climate change.
Always keep your seatbelt on, even when the sign is off.
Jet lag is more than just annoying
Jet lag disrupts your circadian rhythm and impairs mental performance.
It’s linked to a higher risk of accidents, especially driving.
Combat it with sleep, sunlight, and adjusting to local time quickly.
Dehydration
Plane cabins are extremely dry. Alcohol and coffee make it worse.
Drink water regularly, use lip balm and nasal spray to stay comfortable.
Digestive discomfort
Bloating, constipation, and overeating are common inflight issues.
Avoid fizzy drinks and large meals to stay comfortable.
Dental pain mid-flight
Air pressure can cause serious tooth pain, especially after recent dental work.
Get dental procedures done at least 6–8 weeks before flying.
Travel stress is real
Airports, delays, and sleep disruptions add stress.
Emotional strain can escalate into air rage — keep calm to stay onboard.
IATA reports a growing number of unruly passenger incidents.
Bottom line: International air travel is safe, but knowing the risks and planning ahead — from seatbelt safety to hydration, dental checks, and jet lag recovery — will help you land in one piece and actually enjoy your holiday.
