It may be due to dirty air that your sleep quality is bad

To improve the quality of sleep, there may be a lot of people using their hands, but in order to improve the quality of sleep it may be necessary to improve the fundamental living environment. American researchers have published papers suggesting the possibility that air contamination may lower the quality of sleep.

A research team of Associate Professor Martha Billings of the University of Washington conducted a survey to investigate the relationship between sleep quality and air pollution. The research team measured the sleep quality of 1863 subjects living in six cities across the United States using a wristband type wearable terminal and compared the monitoring data of nitrogen dioxide and PM 2.5 over the past 5 years in the city where the subject lives By checking it, we are investigating the relationship between sleep quality and air pollution.

When divided into four groups according to the score of sleep quality, the group with the most sleep quality has a sleep efficiency of 93% or more, whereas the group with the lowest sleep quality has a sleep efficiency of 88% or less He said that. On that basis, sleep efficiency was calculated for the group with the lowest sleep quality taking into account the participants' race, age, weight, smoking status, sleep apnea symptoms and other diseases.

As a result, those who live in an environment with a high nitrogen dioxide level have a probability that the sleep efficiency will be low by 60%, and those who live in an environment with a high PM 2.5 level have a 50% higher probability of lowering sleep efficiency I understood that. In addition, it seems that people who live in an air polluted environment have also found a long time to go to sleep.


In this survey, we are not considering factors that adversely affect the quality of sleeping such as "traffic noise" which is frequent in the air polluted areas, and that individual individuals in the 7-day test period that tracked the quality of sleep Since sleep patterns of subjects are not taken into consideration at all, it has not been proved that air pollution has a direct adverse effect on the quality of sleep. However, in a previous study, it is known from the survey of relevance to hospitalization and death that exposure to nitrogen dioxide can have various adverse effects on physiological functions and biochemical functions of the body, so Canada's Dr. Scott Weichental of McGill University says, "Even if air pollution affects the quality of sleep it is not surprising."
