Why do people feel exhausted even after taking short flights?
People may experience fatigue even after taking short-distance flights due to various reasons, including environmental and physical ones, general physician Dr Narander Singla said. According to consultant physician Dr Hiran S Reddy, the pressure inside aircraft cabins can result in reduced oxygen levels. "This mild hypoxia can cause fatigue, headaches...even on short-haul trips," Dr Reddy added.
