If you struggle to get a good night’s sleep, think about opening your bedroom window or door.
It helps the air circulate at night, leading to better quality sleep, a study found.
Sleepers were less likely to toss and turn and wake up, researchers said.
Scientists believe that poor ventilation leads to a build-up of CO² in the bedroom as a result of respiration.
To test the effect of keeping a window open, researchers tracked the sleep of 17 healthy students. They slept with windows or doors either open or shut.
Levels of CO² were measured in the bedrooms over five days for the study published in the journal Indoor Air.
The findings showed an open window was better for reducing CO² than an open door. However, an open door may be preferable if it is noisy outside.Daily Mail
