Jet lag after a long-haul flight can affect us far longer than the first few days after we arrive – it can last for a whole month, researchers say.
Memory and learning problems can last for four weeks where the time difference is greater than five hours. This is not only significant for passengers on long-haul flights, it raises serious health concerns for crew, such as pilots and cabin staff, who could be regularly flying long-distance.
Researchers from the University of California at Berkeley say it could also have an unforeseen impact on the efficiency of workers in key professions such as medical staff.
