Flight Essentials: 5 Health Items Experts Say You Shouldn't Fly Without

Travellers preparing for a flight may benefit from carrying a small health kit containing five practical essentials: saline nasal spray, lubricating eye drops, sunscreen, compression socks and electrolytes. These items may help address common problems associated with air travel, including dry cabin air, prolonged sitting, dehydration and increased exposure to sunlight. However, individual health needs vary, and travellers should consult a qualified medical professional before using medication or changing an established routine.

Saline nasal spray can help keep the nasal passages moist and reduce crusting caused by dry cabin conditions. Medicated decongestant sprays containing ingredients such as xylometazoline or oxymetazoline work by constricting swollen blood vessels and may provide rapid relief from congestion, according to ENT specialist Dr Shama Kovale. Saline sprays are generally considered the safer option because they moisturise the nasal passages without the same concerns associated with prolonged use of medicated decongestants.

Lubricating eye drops may provide relief from dryness and irritation during a flight, particularly for passengers who spend extended periods looking at phones, tablets or in-flight entertainment screens. Low humidity inside aircraft cabins can make the eyes feel uncomfortable, especially during long journeys. Kovale recommended using appropriate lubricating drops when needed in dry environments, although passengers with existing eye conditions or those using prescription products should seek professional advice.

Sunscreen and moisturiser can help protect the skin during travel. Dermatologist Dr Rinky Kapoor said SPF 50 sunscreen offers protection against ultraviolet radiation associated with premature ageing, pigmentation and skin cancer. She also advised moisturising before boarding because dry cabin air may affect the skin. Travellers expecting to spend time outdoors after arrival should reapply sunscreen at suitable intervals rather than relying solely on a single application before departure.

Compression socks may be useful during long-haul flights, particularly for travellers prone to leg swelling or circulation problems. Internal medicine specialist Dr Narander Singla said the socks apply gentle pressure to the legs, support blood flow and may reduce tiredness and swelling. They can also help lower the risk of deep vein thrombosis linked to prolonged immobility, although passengers should confirm the correct type and fit with a healthcare professional.

Electrolytes, including sodium, potassium, magnesium and calcium, support functions such as fluid balance, nerve activity, muscle function and nutrient movement. They may be helpful for some travellers experiencing fatigue or dizziness, but excessive consumption should be avoided, particularly by people with medical conditions. Essential medicines, documents, chargers, snacks and a change of clothes should also remain easily accessible in carry-on luggage throughout the journey.
