Sleeping with an open window or door can improve sleep


Previously, I told you how drinking tart cherry juice on a regular basis can help improve your sleep and combat insomnia. Now, it turns out there is something else you can do to ensure a good night’s sleep: Open a window or door.

The air that you breathe

According to a new study, opening a door or a window to improve ventilation in your bedroom can help you catch more shuteye.

For the study, a group of healthy volunteers were tracked as they slept over the course of five nights. The researchers placed sensors under the participants’ pillows to see how much they tossed and turned, and they recorded the humidity, temperature, and carbon dioxide levels in each participant’s bedroom.

By the end of the study, it turned out that those who slept in bedrooms with open doors or windows slept more — and woke up and moved around less — than those who battened down all the hatches.

The reason for this is simple: letting in a little air and allowing for better ventilation while you are sleeping made a significant impact on the room environment.

For one thing, increasing ventilation made the rooms slightly cooler — and we know from previous studies that lower temperatures foster better sleep.

The interesting thing is that, compared to the air in closed rooms, the air in open rooms contained less carbon dioxide (CO2), which is the gas you naturally breathe out when you exhale. When CO2 levels rise in your blood, your brain signals your lungs to start pumping in more oxygen, leaving you gasping for air.

Previous studies have shown that the higher the CO2 levels in the air, the longer it takes you to fall asleep, and the less sleep you’re likely to get overall.

So, if you’re struggling to get a good night’s sleep that’s uninterrupted from night until morning, you may not want to be too snug.

Instead… let in some air!

Other natural ways to ensure a good night’s rest involve getting regular exercise and limiting your exposure to TV and electronics close to bedtime.

You can also support your body’s natural sleep cycle by drinking tart cherry juice and supplementing with L-theanine and 5-HTP.
