Nothing ruins a trip faster than an unexpected illness. With a little planning you can cut the risk of getting sick, speed recovery if you do, and keep your plans on track. Below are clear, practical steps you can use before you leave and while you travel.
Bring prescription meds in their original bottles and carry a printed list of doses and your doctor’s contact. Pack basics that actually help: a digital thermometer, pain reliever (acetaminophen or ibuprofen), antihistamine, loperamide for diarrhea, oral rehydration salts, antiseptic wipes, adhesive bandages, a small tube of topical antibiotic, hand sanitizer, sunscreen SPF 30+, and insect repellent (DEET or picaridin works well). Keep all medicines in your carry-on so delays or lost luggage don’t strand you without them.
If you need altitude medicine (acetazolamide) or other prescription treatments, get advice and prescriptions before you go. Some vaccines need weeks to take effect, so check requirements at least 4–6 weeks ahead for destinations with CDC or WHO recommendations.
Food and water safety: in many countries avoid tap water and ice. Drink sealed bottled water, or use boiled/filtered water for brushing teeth. Eat hot-cooked food and fruits you can peel. Street food can be great—pick busy vendors where turnover is high and food is cooked hot.
Sleep and jet lag: shift your sleep schedule a little before departure if you can. Use daylight to reset your clock—get morning sun to wake up after eastward travel, evening light for westward. Short naps help; avoid long daytime sleeps that wreck adjustment.
Move on long flights to lower DVT risk: stand up every hour, do ankle pumps, and consider compression socks for flights over 6–8 hours. Stay hydrated but limit alcohol and excess caffeine, which dehydrate and disrupt sleep.
Bug-bite prevention: use repellents and a permethrin-treated mosquito net or clothing in areas with mosquito-borne diseases. Apply repellent to exposed skin and reapply per product instructions.
If you get sick: many countries have reliable pharmacies and telemedicine options. Know local emergency numbers, keep travel insurance details handy, and have a basic plan for reaching a clinic. For concerning symptoms—high fever, severe dehydration, breathing trouble—seek care quickly.
Quick checklist before you go: check recommended vaccines for your destination, refill prescriptions with extra days’ supply, build a compact health kit, buy travel insurance that covers medical care and evacuation, and save local emergency contacts. A few minutes of prep can save days of trouble on the road.
