Flying often leaves us feeling dehydrated, bloated, or unrested. The enclosed cabin, low humidity, and reduced air pressure take a toll. Here's what happens to your body during air travel, based on established aviation health insights.
At cruising altitude, cabin pressure drops, allowing gases in your digestive system to expand. This leads to bloating, abdominal pain, or constipation—especially if you're sensitive to pressure changes.
Conditions like arthritis flare up due to slight joint swelling from pressure shifts, making movements feel stiffer during flight.
Aircraft cabins have very low humidity, drying out your skin, eyes, and mucous membranes faster. Drink plenty of water to avoid fatigue and headaches; limit alcohol, which worsens dehydration.
Cabin air recirculates, potentially trapping viruses and bacteria. Boost your immunity beforehand and wash hands often to minimize catching a cold.
Sitting for hours stiffens muscles and joints. Stretch and walk the aisle regularly on long flights; compression stockings help prevent leg and ankle swelling.
Crossing time zones disrupts your internal clock. Read our tips against jet lag.
