Pharmacist warns against sleeping pills before flights

Travellers who reach for a sleeping pill to ease a stressful flight may be doing themselves more harm than good, according to pharmacist Seema Khatri from Roseway Labs. In advice reported by multiple outlets, Khatri cautioned against the common habit of taking sedatives before flying, warning that drug-induced sleep is not the same as natural, restorative sleep and can leave passengers groggier and more jet-lagged.

"People imagine that taking a sleeping pill means they'll wake up refreshed at their destination," Khatri said. "But drug-induced sleep is not the same as natural, restorative sleep, and on a plane it can actually leave you groggier and more jet-lagged."

Health risks at altitude

Khatri highlighted several specific risks associated with taking sleeping pills on flights. One of her primary concerns is circulation. "When you're sedated you move far less, and that immobility can increase the risk of deep vein thrombosis," she explained. "Cabins are already dehydrating environments, and sedatives can thicken the blood further, so the two combined aren't a good mix."

The effects of cabin pressure can also amplify the impact of sleeping tablets. At increased altitudes, oxygen levels decline, and Khatri said sedatives may worsen drowsiness, disorientation, or even respiratory issues. "So what might feel like a mild dose on the ground can hit much harder once you're in the air," she highlighted.

Taking sleeping pills at the wrong time can also disrupt the body's internal clock. "If you take at the wrong time, your body clock becomes even more confused," Khatri said. "Instead of easing into the new time zone, you land disoriented and wired."

Who should avoid sedatives

Khatri advised that older travellers, people with breathing conditions such as asthma or sleep apnoea, and anyone with circulation problems should steer clear of sedatives on planes. She noted that even a small dose could pose significant risks for these groups.

Alternative ways to rest

For those seeking rest during a flight, Khatri recommended several non-medicinal alternatives. She suggested herbal teas like chamomile or lemon balm, staying well hydrated, wearing an eye mask, and using noise-cancelling headphones. She also recommended avoiding caffeine before departure. In some reports, she additionally mentioned magnesium glycinate to calm the nervous system.

"These options won't put you into an unnatural sleep cycle, so you arrive fresher and safer," she said.

Khatri advised anyone experiencing sleep problems to consult a medical professional, such as a GP, for guidance rather than relying on sedatives while travelling.
