A neurologist's advice to sleep 20-30 minutes at work has gone viral on the Internet; Onyshchenko said that mainly managers can afford it. The neurologist advised Russians to sleep for 20-30 minutes at work between 1:00 and 3:00 p.m., explaining it as a natural drop in vigor after lunch. The former chief sanitary doctor of Russia, Academician of the Russian Academy of Sciences Gennady Onishchenko, called this practice impractical for the majority: sleeping on a chair in a huge hall with 150 tables, in his words, is "not physiological." "Someone takes advantage of this, managers, for example, who have a separate office, individual companies that can create such conditions. But as a system, it is not applicable," Onishchenko said.
