Why are you cold at night? Check how to choose pajamas based on your bedroom temperature

Do you wake up in the middle of the night feeling cold, even though the bedroom temperature seemed perfect before you went to sleep? This doesn't necessarily mean you need to turn up the radiator. During sleep, your body naturally regulates its temperature, and your thermal comfort is also influenced by your bedding and the sleepwear you wear. It’s not just the thickness of the pajamas that matters, but also the material, the cut, and how much of your body it covers. This is why the same pajamas might provide pleasant warmth one night and prove insufficient the next. Find out how to match your sleepwear to the bedroom temperature and your personal comfort to reduce nighttime chills without the risk of overheating instead.

Why do you feel cold at night even when the bedroom is warm?

A feeling of cold at night can occur because your core body temperature naturally drops while you prepare for sleep and during sleep itself. This is part of your circadian rhythm, not necessarily a sign that conditions in the bedroom are poor. Individual sensitivity to cold, bedding, and nightwear, which creates an extra layer between your skin and the environment, also play a role.

Studies on sleep and thermoregulation show a close link between falling asleep and changes in body temperature. The body begins to lower its temperature even before sleep, and this process continues throughout its various phases. Because of this, the temperature that felt completely comfortable in the evening may be perceived differently by morning.

However, this does not mean that the solution is always to heat the bedroom more. A room temperature that is too high can also disrupt sleep and hinder natural thermoregulation. Often, a better solution is to adjust the layers closest to the body—bedding and appropriate nightwear.

During colder months, it is worth paying attention primarily to the cut and material of your pajamas. Long legs, sleeves, and a skin-friendly material help reduce heat loss without the need to excessively raise the room temperature. This is why women’s long-sleeve pajamas can work particularly well for women who regularly wake up feeling cold.

Balance is essential here. The warmest pajamas are not always the best pajamas. If the material and cut trap too much heat, comfort can quickly turn into overheating. That is precisely why it is worth choosing nightwear not just based on the season, but primarily on the actual temperature in the bedroom at night.

What bedroom temperature is best for a comfortable sleep?

There is no single ideal bedroom temperature for everyone; however, a cooler room usually works better for sleep than a heavily heated interior. Around 18°C is often cited as a practical reference point for adults, although individual comfort may require a slightly higher or lower temperature. Instead of stubbornly sticking to one value, it is worth observing your body's own reactions.

Ambient temperature affects heat exchange between the body and the environment. If it is too warm, it is harder for the body to shed excess heat. When the bedroom becomes chilly, properly chosen pajamas and bedding help create a comfortable microclimate around your skin. Therefore, adjusting the thermostat is only one element of nighttime thermal comfort.

The ranges in the table should be treated as guidelines—temperature perception is individual and depends on factors such as bedding, humidity, clothing, and personal sensitivity to cold.

If the temperature in your bedroom stays around 16–19°C at night, yet your hands or feet often feel cold, women’s long pajamas could be a good direction. This doesn't mean choosing the thickest model possible. It is more important to combine the right length with a material that ensures thermal comfort and is pleasant to the skin.

It is also worth doing a simple "three-night test." For a few consecutive evenings, check the bedroom temperature before sleep and upon waking, and take note of whether you wake up because of the cold or, conversely, because of excessive heat. Such observation can tell you more about your needs than a universal number on a thermometer and will make it easier to match your pajamas to the actual conditions in your bedroom.

How to choose pajamas based on the bedroom temperature?

The cooler the bedroom, the more important the length of the sleeves and legs, the material properties, and the pajama cut become. However, you shouldn't just follow the simple rule of "the thicker, the better." Pajamas should help maintain thermal comfort but not lead to overheating in the second half of the night.

If the temperature regularly drops below the level where you feel comfortable, a model that covers more of your body will be a good choice. On truly cold nights, it is worth looking into warm brushed cotton knit pajamas. The brushed inner surface of the fabric provides a pleasant feeling of being wrapped up, so this variant can be treated as a solution for the coldest time of year.

In a moderately cool bedroom, you don't always need a material that is quite as warm. In such cases, long styles that cover your arms and legs but remain loose work well. An example is warm pajamas with a boat neckline and straight trousers. The looser fit increases comfort when shifting positions in bed, and long trousers and sleeves help reduce direct skin contact with the cool air.

When choosing pajamas, it is also worth considering how the temperature in your bedroom changes throughout the night. In a heated apartment, it might be pleasantly warm in the evening, but significantly colder a few hours later. In such a situation, light pajamas chosen based on conditions at 10:00 PM might not provide the same comfort at 4:00 AM.

A simple rule is helpful: if your shoulders and legs are usually the first to get cold, start by switching to a long style rather than immediately choosing the thickest material available. If you still feel cold despite the full length, the next step could be more enveloping pajamas. Conversely, if you wake up sweaty, take it as a sign that you need a lighter layer or a lower level of insulation.

High-quality nightwear should combine thermal comfort with convenience during long hours of wear. That is why at Oh!Zuza, not only the materials are important, but also refined cuts and details. Thanks to this, fashionable women’s pajamas can be both a practical part of your night wardrobe and an aesthetic choice for your evening relaxation.

Which pajama material best helps maintain thermal comfort?

Your pajama material should be matched not only to the bedroom temperature but also to whether you have a tendency to get cold or overheat during sleep. It's not just the thickness of the material that counts. Breathability, moisture-wicking ability, and how it behaves in contact with the skin over several hours are also significant.

In practice, it is worth paying attention to a few solutions:

• Viscose – it is soft, pleasant to the touch, and works well for nightwear. It is a good choice for people who do not want to sleep in heavy, tightly wrapping pajamas. Women’s viscose pajamas can be particularly interesting when you want to combine thermal comfort with lightness.
• Brushed cotton knit – this can be a good solution for noticeably colder nights. The gently brushed surface provides a more enveloping feeling, so it is worth considering, especially in winter or in a cold bedroom.
• Viscose satin – it should not be equated simply with "satin," because satin describes a type of weave, not a specific raw material. A variant made of viscose combines characteristic smoothness and an elegant finish with the properties of viscose fibers. The material provides a pleasant cooling sensation and does not retain heat as effectively as fabrics chosen for lower temperatures. For this reason, viscose satin will work better during warmer nights, while it will not be the best choice for cold ones.
• Lace as a detail – it primarily serves a decorative function, so thermal comfort is mainly determined by the material from which the main part of the pajamas is made. Lace trim, however, allows you to combine functionality with a more feminine aesthetic.

A good example of combining a long style with an elegant character is the Sonnet long pajamas with a fold-over collar – merlot. This type of model shows that pajamas for colder nights do not have to resemble heavy winter clothing—they can provide more body coverage while maintaining a refined, feminine form.

The most important thing is finding your own level of "coziness." If you feel cold despite long sleeves and legs, you might need a warmer material. If, however, you get too hot in long pajamas, a thinner viscose might be a better solution. This is why when choosing nightwear, it is worth analyzing three elements simultaneously: bedroom temperature, cut, and material properties.

What should you wear to sleep if you often get cold at night?

If you regularly feel cold during sleep, start with long-sleeve and long-leg pajamas, and only then increase the thickness of the material. This approach allows you to better tailor your nightwear to your own needs and reduces the risk that by solving the cold problem, you will start waking up due to overheating.

A good starting point is classic women’s pajamas consisting of a shirt or blouse and long trousers. Such a style covers a larger surface area of the body while not restricting movement when changing positions. When choosing, also pay attention to cuffs, the neckline, and the width of the legs—these seemingly small differences can affect how you perceive the cold.

If you care about a more elegant form, an example could be the Poem long button-down pajamas with lace – red wine. The long cut will work well in cooler conditions, while the lace finish gives the whole thing a subtle character. This shows that practical nightwear does not have to mean sacrificing aesthetics.

When choosing pajamas for colder nights, it is worth paying attention first to the length of the style and the type of material, rather than just looking for the thickest model. Well-chosen pajamas should pleasantly wrap the body, but still provide freedom during sleep. This is especially important in bedrooms where the temperature drops significantly in the morning.

If, however, you like to relax in your pajamas in the evening before going to bed, an interesting alternative is the Jackie loungewear pajamas with wide trousers – almond milk. The loose style with wide trousers fits the idea of nightwear that can also accompany you during a quiet evening at home.

It is also worth considering whether pajamas are the best form of nightwear for you. If you are hesitant between a two-piece set and a nightgown, comparing nightgown vs. pajamas - what to choose for sleep will be helpful. Both solutions provide a different feeling during sleep, which is why both the bedroom temperature and personal habits are important.

At Oh!Zuza, great importance is placed on the quality of materials, the convenience of cuts, and careful finishing. Thanks to this, in the Oh!Zuza fashionable women’s lingerie store offer, you can look for nightwear not only according to aesthetics but also according to your own rest style and preferred level of "envelopment." The availability of a wide size range, in selected models from XS to 4XL, additionally makes it easier to find the right style.

How to avoid both being chilled and overheating while sleeping?

The best way is to adjust your pajamas to the actual bedroom temperature and your own body's reaction, instead of following only the season. In winter, in a well-heated apartment, very warm pajamas may prove unnecessary, while in autumn, in a cold bedroom, a light model may not provide sufficient comfort.

A good warning sign is waking up at night. If you kick off your duvet, feel hot, or wake up sweaty, the set may be too warm. If, on the other hand, you instinctively curl up under the duvet and your shoulders or legs are cold, it is worth trying a longer style or a more enveloping material. Do not change all elements at once—a single modification makes it easier to evaluate what actually improved comfort.

When choosing, you can apply a simple three-step rule:

• Check the temperature – measure it not only before sleep but also in the morning, especially if the heating is limited at night.
• Observe your body – pay attention to whether you are more bothered by the cold or by excessive heat and moisture against your skin.
• Change one layer – before turning up the heat, try a longer style, a different material, or appropriately chosen bedding.

In a bedroom with a moderate temperature, long but not-too-heavy pajamas can be a good solution. An example is the Sonnet long pajamas with a fold-over collar – merlot, which combines a fuller style with an elegant form. However, if this particular model has already appeared in your wardrobe or you are looking for a different cut, it is worth being guided primarily by your own perception of temperature, not just the appearance of the pajamas.

Thermal comfort does not exclude a more feminine aesthetic either. Sensual nightwear can be made from soft, high-quality materials and designed in such a way that comfort remains just as important as details or style. This is especially important for lingerie worn for many hours directly against the skin.

Ultimately, a thermometer only gives you a reference point. Two people sleeping in a room at 18°C may need completely different nightwear. The best pajamas are therefore not automatically the warmest model, but the one in which you do not have to fight against cold or excess heat throughout the night. Precisely this combination of bedroom temperature, material properties, style length, and your own feelings allows you to find a comfortable balance.

How to choose pajamas so you don't get cold at night? Summary

If you feel cold at night, don't start by turning up the heating in the bedroom – first check if your pajamas are suited to the conditions in which you actually sleep. In a cooler room, it is worth opting for long sleeves and legs, and if you are more sensitive to the cold, for a more enveloping fabric as well. If, on the other hand, you wake up feeling hot, lighter, breathable nightwear might be a better choice.

There is no single pair of pajamas that is right for everyone. Thermal comfort depends on room temperature, bedding, style, and material properties, but above all on individual sensitivity to cold. That is why it is worth observing your own body for a few nights and making one change at a time. The goal is not to keep the body as warm as possible, but to create conditions where neither cold nor overheating will disrupt your night's rest.
