12 Smart Packing Items for Health and Comfort in Your Carry-On

6. Circulation support: compression socks and movement aids

Prolonged sitting can cause swelling and discomfort, and for some people it increases the risk of circulation problems. Compression socks are a simple, evidence-based way to reduce leg swelling and support circulation on long flights. Choose a comfortable, breathable material and the right compression level for your needs; if you have vascular conditions, consult your clinician about medical-grade options. In-seat footrests or inflatable foot hammocks change posture and reduce pressure on the lower back. Pair compression with light in-seat exercises—ankle circles, calf raises, and short walks when allowed—to keep blood flowing. Packing socks in a top pocket of your carry-on ensures you can slip them on pre-boarding and keep them within reach for changes mid-flight. These aids are low-cost and unobtrusive, and they make a noticeable difference in comfort and recovery after hours of sitting.
