A third of Russian citizens who participated in a survey on the quality of sleep reported that with the advent of spring they began to sleep worse.
In total, more than a thousand people aged 20–68 from several large Russian cities took part in the survey, which was conducted on May 14–17, 2021 by one of the mattress manufacturing companies operating in Russia.
An analysis of the causes of sleep disorders showed that 27% of survey participants suffer from allergies, which is one of the causes of poor sleep quality. Another 28% complained about the sun, which now shines through the windows too early. 26% of respondents stopped getting enough sleep because of the stuffiness and heat, and 5% who decided to open the windows suffer from insomnia due to street noise. Finally, another 8% simply believe that their bed is not comfortable enough.
More than a third of the study participants (35%) began to use blackout curtains more actively with the advent of spring. 34% plan to leave for the summer to live in a country house or in another city or even a region. 9% use a sleep mask to combat factors that interfere with sleep, and 6% use earplugs. 15% of respondents choose drugs to improve sleep — sedatives and hypnotics, and only 5% go to doctors.
