Solve lack of sleep in summer with air conditioning! How to choose the comfortable temperature and pajamas

Summer is finally here again this year.

Many people have a hard time falling asleep on hot, humid summer nights.

Lack of sleep can not only lead to poor physical condition but can also cause heat stroke. To survive the hot summer, it is important to create a better sleeping environment.

So, this time we will introduce the basics for sleeping comfortably in the summer and how to choose the best pajamas.

Comfortable sleep environment for summer nights

The human body regulates its temperature by producing heat internally and releasing heat from the surface of the body.

It is generally said that the temperature at which humans can feel comfortable when naked is 27 to 31 degrees Celsius, and the optimal conditions under clothes or in bed are a temperature of 31 to 33 degrees Celsius and a humidity level of 50 to 60%.

To create this condition in the summer, it is recommended to maintain the following indoor environment (indoor temperature and humidity).

When sleeping in long-sleeved, long-pants pajamas and under a summer duvet
→Temperature around 26℃, humidity 50-60%

When sleeping in short-sleeved pajamas and shorts, with a thin bedding such as a towel blanket
→Temperature 27-28℃, humidity 50-60%

The numbers alone may not make much sense, but to put it simply, the ideal environment is one that is close to the comfortable sleep you get in early summer or early autumn.

By the way, if you sleep naked, it is said that a room temperature of 29°C and humidity of around 50-60% is ideal.

Long sleeves or short sleeves? Which do you prefer to sleep in?

When it comes to pajamas to sleep, you can wear either long sleeves and long pants or short sleeves and shorts, whichever you prefer.

However, for those who are prone to getting cold or who sleep in an awkward position, we recommend pajamas with long sleeves and long pants, which make it easier to regulate body temperature.

Many people say, "When I sleep with the air conditioner on, my body gets cold and I feel fatigued." However, if the temperature isn't too low, this is because the room temperature is not in balance with the temperature of your clothing and bedding.

Having the air conditioner on is like being in early summer or early autumn, so you can solve this problem by adjusting your balance and sleeping in long-sleeved and long-pants pajamas.

How to use air conditioners correctly

Some people turn on the air conditioner at a low temperature setting and then use a timer to turn it off when they go to bed, but this is not recommended because once the air conditioner is turned off, the temperature and humidity will return to their original settings, making it uncomfortable to sleep.

You will sleep better if you leave the air conditioner on until morning rather than using a timer to keep the temperature and humidity constant.

Many people are concerned about their electricity bills, but some research has shown that air conditioners consume the most electricity when they are started up and consume relatively little electricity when operating continuously, so leaving the air conditioner on actually consumes less electricity than turning it on and off.

If you set the temperature a little higher, you may be able to save on your electricity bill by leaving it on from before you go to bed until the morning.

In addition, if someone who is sensitive to heat and someone who is sensitive to cold sleep together in the same bedroom, do not hesitate to adjust the air conditioner settings to suit the person who is sensitive to heat.

You can easily adjust the temperature with pajamas and bedding, but that's not the case with heat.

It would be a good idea to set the air conditioner so that the person who gets hot easily can sleep comfortably in short sleeves and shorts, while deciding on the pajamas and bedding for the person who gets cold easily.

"Cotton gauze" is the best for summer pajamas

As mentioned earlier, if you are using air conditioning to keep the indoor environment cool, the best pajamas to wear are long sleeves and long pants, as they make it easier to regulate your body temperature.

Of course, the material of the fabric is important, but by covering your wrists and ankles, you can create a comfortable temperature zone between the outside air and your skin.

On the other hand, if you prefer to sleep more comfortably in slightly warmer rooms with your arms and legs exposed, we recommend short sleeves and shorts.

Short-sleeved shorts have wide openings at the collar, sleeves, and hem to prevent heat from building up inside the garment, and the overall shape is loose and roomy for a comfortable sleep. Short-sleeved shorts also have the advantage of allowing a large range of motion in the joints, making it easier to turn over in your sleep.

The best material for pajamas is cotton gauze.

When we think of summer, we think of linen, which is highly absorbent and feels smooth against the skin, but linen and ramie have stiffer fibers than cotton and do not conform to the skin as well, so supple cotton is superior when it comes to keeping the environment inside clothing comfortable.

Pajamas for hot seasons need to efficiently release or absorb heat, water vapor, and sweat from the body to keep the temperature and humidity inside the garment at a comfortable level, and also quickly diffuse moisture to allow it to dry.

The best way to meet these requirements is to combine cotton, which has excellent water absorption and moisture wicking properties, with gauze, which has excellent breathability and quick-drying properties.

Change the temperature setting of your air conditioner!? Coolest gauze pajamas

From here, we will introduce you to Crepe Gauze® pajamas, which are not only cool but also packed with functions to help you get a good night's sleep, even on hot summer nights.

The fabric for these pajamas is a three-layer gauze developed based on towel manufacturing techniques. It is woven into three layers using threads that are about 40% thinner than usual, and the surface of the fabric is relaxed to create wrinkles that resemble crepe fabric (a woven fabric with uneven shrinkage and creases), hence the name crepe gauze.

Cotton gauze is known for its high breathability, and Crepe Gauze® is 1.5 to 1.8 times more breathable than conventional gauze, and a whopping 7 times more breathable than a cotton T-shirt!

This gauze is so cool that it feels like the breeze can pass through it.

In addition, because it is absorbent, it does not become sticky even when you sweat, and since it quickly diffuses absorbed sweat and dries over a wide surface area, you can also expect a cooling effect due to the latent heat of vaporization.

You'll be able to sleep comfortably even on stuffy, uncomfortable nights when wearing a cotton T-shirt, so this may change the temperature setting of your air conditioner.

One of its features is that the fabric contains a lot of air, making it highly insulating.

It may seem surprising that summer pajamas are warm, but since the temperature often drops in the mornings, moderate heat retention is important for ensuring a comfortable sleep.

Its heat retention is comparable to that of cotton flannel, a typical material for winter pajamas, but this is due to the air layer contained within the fabric. At the same time, it is highly breathable, so you won't feel stuffy or hot.

In addition, the silhouette is slightly loose so as not to restrict movement, and the openings at the collar, sleeves, hem, etc. are wide to allow hot air to escape easily from inside the garment.

Crepe Gauze® also has a wide selection of loungewear items such as T-shirts and dresses.
