It's finally winter in earnest.
Of course it's cold outside, but it's cold even in the room! I think there are many people.
Even with the heater on, the floor is cold, and the windows are drafty.
Therefore, we have summarized cold protection ideas for rooms that even amateurs can easily do.

why is the room cold
There are a number of reasons why a room is cold and it doesn't get warm even after turning on the heater.
Here are 3 common causes
・Draft
・Cold air from windows, floors and walls
・Cold draft phenomenon
Feel like this.
Let's take a look at each one!
[Draft]
As the name suggests, outside air enters through a small gap.
The outside air in winter is naturally very cold, so the room itself is getting colder and colder due to the cold air.
Drafts are particularly common near windows.
In fact, many window frames have small holes for ventilation.
Also, if it's a newly built property, it doesn't seem to be a problem, but if it's an older property, drafts are often the cause of the cold.
When the window frames and the building itself deteriorate and warp, gaps will inevitably form, through which the wind will enter.
Even in a newly built property, if you leave the ventilation fan open, it will get quite cold.
[Cold air from windows/floors/walls]
If you live in an apartment, corner rooms are popular.
The reason for this is that there are less noise problems if there is no neighbor, and there are many large condominiums with slightly different layouts for corner rooms.
For the same reason, there seems to be a certain popularity because you can live on the second floor of a property with a garage on the first floor without worrying about footsteps...
big pitfalls.
In northern countries, people tend to avoid rooms above garages and corner rooms.
The reason is because it's cold anyway.
Both of them have an image of being comfortable to live in, but both the corner room and the garage have an overwhelmingly large area that comes in contact with the outside air, making it easy to get cold.
The cold air that travels through the walls and floor is quite troublesome, and the more areas you touch, the colder it gets.
[Cold draft phenomenon]
Have you ever had the experience of feeling warm above your head when you thought that it would not be warm even if you turned on the heater when it was cold?
This is a phenomenon caused by the difference in the properties of cold air and warm air, and is called the cold draft phenomenon.
It has to do with the fact that cold air goes down and warm air goes up.
People are in the lower part of the room, so it feels like the heating doesn't work.
Bad effects of cold room on the body
A cold room is bad for your body.
Heart disease is the most common.
The sudden rise and fall in blood pressure due to the difference in temperature between a heated room and a non-heated hallway or bathroom can lead to myocardial infarction or stroke.
The adverse effects on the body caused by such a temperature difference in the room is called "heat shock", and it is said that 14,000 people die every year!
This is nearly four times the number of people who die in traffic accidents.
It's never someone else's problem...
Cold protection techniques for rooms that can be done with a simple DIY feeling
Cold rooms are bad for your health! However, remodeling costs money, and you can't renovate if you rent in the first place.
Therefore, we have summarized cold protection measures that can be done in a simple DIY sense for each point where it gets cold!
There are ideas that even women living alone can easily do, such as countermeasures that can be obtained with items that can be obtained at a uniform price of 100 yen, countermeasures that can be done immediately tomorrow, and so on.
Let's keep warm and have a comfortable winter!
window edition
Cold air from around the windows is often cited as the cause of cold rooms.
First of all, if you do something here, the temperature of the room will change considerably.

It is the so-called bubble wrap.
Air packing for packing is a polyethylene sheet with a lot of puffy air bubbles, but recently, a bubble sheet for cold protection has appeared.
Easy to get at home centers and cheap ones at 100 yen!

By creating a layer of air between the window and the room, cold air is less likely to be transmitted.
It is easy to install even if you live alone or a woman because you just cut it to fit the size of the window and stick it on.
It doesn't look good if you put it on the entire window, so just stick it in the area about 50 cm below where cold air tends to accumulate.

It's OK if you simply keep drafts from coming in!
Prevent drafts by pasting sponge-like tape on the window sash.
It is a great item that can prevent not only the cold air in winter, but also pollen and insects from entering.
You can also get it for 100 yen.

Of course it can be used for windows, but it can also be used for drafts from doors in the room.
Even if the room is warmed up, it will be useless if the cold air from the corridor flows in.

Cold air from under the floor can be prevented with an aluminum sheet.
Not only does it prevent cold air, but it also prevents warm air from escaping, so just laying one on it will make you feel quite comfortable.
Small ones are available at 100 yen, but larger ones may be cheaper at home centers.

All you have to do is spread the aluminum sheet and place it under the carpet or rug.
It's even warmer when used with a kotatsu!

Cork is a material with low thermal conductivity and excellent insulation, and is said to be more effective in preventing cold than laying carpets and rugs.
In addition, you can expect a soundproofing effect to the downstairs by laying it all over the floor.
It is also useful in homes with pets and small children.

Many cork mats are sold in a jointed style, and since all you have to do is lay them down, even beginners can install them easily.
If you put it on the entire floor, it will be a large-scale work such as moving furniture, so it seems that it will be difficult to realize only at the timing of cleaning or moving house.
Of course, you can also cover only the visible part of the floor, so let's start with a small area.

It is also a great point that you can replace only that part if it gets dirty.

What do you use to store hot water in the bathtub?
I think that many people probably use a faucet or an automatic water heater to store water, but in winter it is recommended to use a shower to store water.
By accumulating hot water in the shower, the entire bathroom is covered with steam and the temperature rises.
As soon as you enter the bathroom, you will not feel like "Wow! It's cold!"
When you take a shower, the hot water is exposed to the air for a long time, and the temperature will drop, so it is better to set the temperature slightly higher than usual.
[Floor sheet]

The floor of the bathroom is cold, and sometimes you need to be prepared to step on it.
Recently, even non-cold sheets for bath floors are on sale!
Just by laying a single sheet, you will be relieved from the chilling feeling when you step on it, and it will be less slippery, so it will also help prevent falls.
However, it is a little expensive and the installation is large...[Insulation material]

In rental apartments and condominiums, there may not be many rooms with windows in the bathroom, but if there is a window, the cold air from there is considerable.
The windows in bathrooms are not very big, and most bathrooms these days have a good ventilation function, so it's not a good idea to block the windows.
A thicker insulation material is used. You can get it for less than 1,000 yen at home centers.
Simply cut the insulation to fit the size of the inside of your window and snap it in.
You can easily remove it by attaching it with a string, so you can remove it during the day and keep it ventilated.
Extra edition
[circulator]
Inexpensive ★☆☆☆☆
Ease ★★★☆☆
Cold protection ★★★★☆

As introduced in the cold draft phenomenon, cold air tends to go down and warm air goes up.
If the room doesn't get warm even with the heater turned on, or if it's difficult to hear the heating in a large room, we recommend using a circulator to stir the air in the room.
Mixing hot and cold air evenly warms the entire room.
Say goodbye to cold feet with a circulator.
