Why is my Room so Hot

Do you wake up in the middle of night damped in sweats?

Or just always end up feeling hot when you enter that one specific room?

Our houses have bedrooms in different locations, resulting in temperature variation across them.

If you’re sick of trying different solutions, its time you study the causes first.

Why is my room so hot?

What could possibly be heating your room up may take you by surprise.

Getting hold of the situation is not as difficult as identifying the problem.

Here are few tips that will help you understand and fix that room that’s too hot.

1. Insufficient Insulation

Insufficient Insulation In House

Scientifically speaking, the key reason for higher room temperatures is due to the inability of windows and doors to keep the heat from coming inside. i.e. inadequate insulation.

Usually double pane windows allow for considerably lesser heat to pass through, keeping the temperature rise under control.

This might be one of the factors that hasn’t grabbed your attention as yet.

Therefore, it is important that the doors and windows are well insulated.

Insulated window coverings can also be of great help when you’re trying to beat the heat.

2. Windows facing the West

If you are wondering, why is my room so hot compared to rest of house, here is the answer.

If your bedroom window(s) are facing North or West, the room would be heated up considerably more than rest of the house, especially during summers.

Although windows facing the West and North are desirable for houses in colder climate areas, they’re definitely one of the lesser known reasons for a hotter room.

This is where insulation and window overhangs come into play.

They reduce the amount of heat entering the room, making it slightly cooler by dropping the temperature down a bit.

You can also use thermally lined blinds to limit the sunlight that enters your room.

3. Faulty Ductwork

Faulty Ductworks

Since there is a whole ventilation system that works to provide the optimum temperature for comfortable living, it requires maintenance and frequent cleaning.

If you’re experiencing temperatures higher than usual, despite the temperature range varying much outside, chances are that the air ducts have been clogged with dust and debris, or there is a leakage somewhere.

Leaks in the ventilation system and uninsulated ducts lose much of the cooling before it reaches your room. 

Both conditions call for repair and maintenance work to bring the temperature down.

4. High Ceilings

High Ceiling

High ceilings are often built for their expansive look and grand appearance but the cons are often always ignored.

High ceiling rooms usually have long windows, which means more sunlight and hotter rooms.

If the ventilation system is perfectly alright, no windows are facing the West, and the insulation is acceptable, and your energy bills are still going up, its because of the high ceilings.

High ceilings prolong air circulation and it takes more than usual to cool down the whole room.

The air conditioner needs to stay switched on for longer, in turn increasing your electricity bills.

5. Bedroom Location

Bedroom above garage hot

If your bedroom is located above the garage, chances of it being hotter are greater than ever.

This is because these rooms have three exposed walls compared to the one of other bedrooms.

That means 3 times more heat than an average room.

Secondly, such rooms are usually the last on the receiving end of the duct-work, hence a reduced airflow.

Other factors that may contribute to heating your room up include bad duct designs and installation.

While other factors may be easier to spot, it can be quite a task to figure this out.

Having an expert review the duct design of the home can tell you about certain gaps and their fixable measures.

6. Bedding

Bad matress reason for heat

Another factor contributing to a hotter room could be your mattresses, sheets, pillows or even pillow covers.

Many bedding materials are good insulators and do not allow heat to pass through, thus retaining heat and making the overall sleep experience hotter.

If you have a big room that takes time to cool, you can always go for breathable sheets, latex foams or cooling mattress toppers like Chilipad.

2. Sleep at a Lower Level

Sleep on a lower levels

Sleeping at a lower level than the bed, affects how hot or cool you sleep.


Since warm air rises, and cooler air being dense, stays down, the air on lower levels is cooler.

Therefore, this lets you sleep cool, and beat the summer heat.

3. Go for a Gel Mattress

Go for a gel mattress

Memory foam mattresses retain heat and could be one of the biggest reasons why you might have been sleeping hot.

Although there are other advanced mattresses pads to let you sleep cool, gel mattresses are one of the simplest solutions to sleeping hot.

Working just like a cooling gel pad, this works best in an air conditioned room.

The gel in the bed layering gets cooled down swiftly, making the bed cold and cosy, and your body temperature prevents it from getting too cold during the night.

4. Take a Shower Before Sleeping

Take A Cold Shower Before Sleeping

Another measure that can be taken to sleep cool, is showering before you go to bed.

Sleeping with damp hair keeps you cooler throughout the night and prevents your body temperature from rising.

5. Cool Bedding

Cool Beddings

Not only can you find water cooled mattress pads like Chilipad, but there are multiple bedding options that you can invest in.

From cooling pillows to temperature regulating sheets and comforters for night sweats, there is a wide variety to choose from.

In other products, a lower thread count usually indicates a cooler fabric.

Keep that in mind when purchasing your next duvet cover or any bedding item for that matter.

6. Sleep with Cotton Clothes On

Sleeping Cotton Clothes

No matter how tempting sleeping without clothes on may be, you should sleep with some light absorbent clothes on.

Sleeping with cotton pyjamas or shirts on soaks up the sweat and lets air pass through.

This keeps you cool through the night, which our body can not do on our own.

Removing a sheet layering or two from the bed also makes a difference, since the more the sheets, the more heat they retain.

Sleeping in a hot room is nothing less than worst nightmare. If these tips have helped you
