Why You Should Sleep with Your Bedroom Door Closed

Sleeping with your bedroom door closed has several important benefits that make keeping the door closed a smart choice for a good night’s sleep. Here’s why:

Better Temperature Control

For a peaceful night’s sleep, it’s crucial to have your bedroom door close because it helps keep the temperature slightly lower, ideally between 60 and 67 degrees, which, in turn, reduces night sweats as your body tends to heat up during sleep, are going through menopause, or are generally overheating from the hot weather.

Keep Your Bedroom Quiet

Closing your bedroom door contributes to noise reduction, along with the other ways it fosters a harmonious atmosphere. One of our tips for blocking out bedroom noise is to even invest in a thicker bedroom door to better muffle outside noise.

However, some people may find background noise soothing, so how much noise reduction you need can be a matter of individual preference.

Slow Down the Spread of House Fires

Sleeping with your bedroom door closed is a practice that significantly improves your chances of surviving a house fire. According to the FSRI, closing your door can greatly decrease carbon monoxide levels from 10,000 PPM to 1,000 PPM when compared to leaving it open.

Sleeping with the Bedroom Door Open a Crack

While the debate on whether it’s better to sleep with the bedroom door fully open or closed continues, an effective compromise can be leaving your door open just a crack. This balanced approach provides some benefits of an open door while still maintaining privacy and noise reduction.

Cracking your bedroom door open a few inches can offer ventilation to improve air quality and temperature regulation. The airflow facilitates fresh oxygen circulating in and stale air circulating out. This small opening may be enough to prevent stuffiness that could impair sleep.

Leaving the door ajar also allows some ambient lighting from the hallway or another room to filter in. This can create a soothing glow in the bedroom and help regulate your circadian rhythm. Early morning light entering through a cracked door can provide a natural transition into wakefulness.

Having the door open just a sliver also makes it easier to hear any concerning noises elsewhere in the house. You can remain alert to potential safety issues. However, because the door is mostly closed, louder noises are still muffled.

Children or pets can also be more readily monitored through a slightly open door, while still giving them a separate sleep space. Overall, a cracked door balances their need for independence and your ability to check on them.

Despite the benefits, remember to consider fire safety as well when sleeping with the door open a crack. While it does not compromise safety as much as leaving the door fully open, having it ajar can allow more air flow and accelerate the spread of smoke and fire. Make sure your smoke detectors are functioning properly.

Experiment to find the ideal minimal gap that lets in adequate fresh air and ambient light for your needs. The right width varies based on factors like room size, door thickness, and more. Overall, a door open just a few inches can be the sweet spot for balancing optimal sleep with safety.

It is important to keep in mind that whether to keep your bedroom door open or closed is a personal decision, Dr. Jing Zhang suggests, that some people feel better with the door open while others find it stressful and vice versa, so don’t be afraid to take the time to figure out what works best for you.


Should I sleep with my bedroom door locked or unlocked?

The usual advice of sleep and safety experts is to keep your bedroom door unlocked while sleeping. In the event of an emergency, having the door unlocked can make a quick exit easier, and also ensure others can readily access your room if needed.

However, personal preferences and individual circumstances may influence this decision. Some people prefer to lock their doors for added security and privacy, especially in shared living situations.

Why do I feel uncomfortable with my bedroom door open?

Feeling uncomfortable with an open bedroom door can stem from a variety of factors, including a desire for privacy, a need for a quiet environment, or a sense of vulnerability. Some individuals prefer to have their personal space closed off to create a sense of security and seclusion. Others may feel uneasy if their door isn’t left open at night.

Understanding and addressing the specific reasons behind your discomfort can help create a more conducive sleep environment.

Should kids’ doors be open or closed at night?

Keeping your child’s door open or closed can depend on their age, individual needs, and the child’s comfort levels. While some parents prefer to leave the doors open to monitor their children more easily and provide a sense of security, others may choose to close the doors to ensure privacy and a quiet sleeping environment. It’s also important to consider fire safety.

Communication with your child can help in making this decision.

Is it OK to sleep with a door and window closed?

For some sleepers, closed windows and doors can help maintain a consistent room temperature and reduce external noise, creating a quieter and more comfortable sleeping environment. However, it is essential to ensure proper ventilation and air circulation in the room to prevent stuffiness and promote a healthy sleep atmosphere. It’s also important to make sure the room is temperature-controlled.

Sleeping with your door closed can also enhance fire safety by preventing the rapid spread of smoke and flames. In case your smoke alarm sounds, it’s crucial to be prepared. Ensure you have a well-thought-out plan that includes escape routes from each room and a designated meeting spot outside your home for all family members.

Is it okay to sleep with the bedroom door open?

Some people may prefer an open door to create a more accessible and inviting atmosphere. Others may opt for a closed door to establish privacy and a quiet sleeping space. Factors such as personal security, fire safety, and noise levels can influence the decision to sleep with the bedroom door open or closed.


Whether to sleep with your bedroom door open or closed depends on your individual needs and preferences. For a more restful night’s sleep, consider factors like temperature control, air circulation, and safety.

Keep in mind that the choice to sleep with your bedroom door open or closed can greatly impact the atmosphere in your living space. So it’s essential to find what works best for you and your well-being.
