5 reasons why bedrooms need windows

Doesn’t a bedroom without a window looks like a jail? (I’ve never been there) Whatever, here are some solid reasons why bedrooms need windows.

As an emergency exit:

As we mentioned earlier, windows can be an emergency exit if something terrible happens. Who wants to sleep in a place with only one way to escape?

Although those situations do not occur often, we hope no one has to face a situation like that. But it’s always better to have a second option for safety.

Air quality:

It’s tough to maintain the air quality if there is no proper ventilation system in a windowless bedroom.

The carbon dioxide you release can get stuck in your room and make the room air unhealthy. This can cause heart and blood disease if you sleep in this type of room for years.

Humidity and mold:

When you live in a room with a poor ventilation system with no window, humidity can trap you inside the room. The moisture will dampen the carpet and wall, and molds can grow in them.

Sleeping in a room with mold can be dangerous. The molds can cause skin disease, respiratory irritation and allergy to sensitive people.

Setting a dehumidifier can control the humidity, and proper light and ventilation will help destroy the mold colony in your bedroom.

Sleep quality:

It’s evident that if your room’s air quality and humidity are not suitable, you will not have a good sleep.

Breathing excess carbon dioxide can significantly reduce the quality of your sleep. You will have difficulty sleeping and possibly have many nightmares in this type of bedroom.

Difficulty focusing and mental health:

The air and light in your room significantly affect your mental health and ability to focus.
