You are not alone if you find yourself tossing and turning in your sleep as a result of the heat. Sheets are the foundation of your home, and the way they are constructed has a significant impact on your temperature, especially in regard to the number of thread counts. 

Thread count is defined by the number of horizontal and vertical threads (also known as weft and warp respectively) being weaved into one square inch of fabric. This is why bed sheets thread count is important when it comes to warm and humid weather, and why utilising high thread count sheets in Singapore is not recommended.

But before we get into detail, do check out our guide on how to buy the perfect bed sheets for you and your loved ones if you are still unsure of how to go about it.

How Does Thread Count Affect Bed Sheet Cooling Abilities?

To enhance the thread count of their bed sheets and make them appear more opulent, several bedsheets in Singapore utilise multiple-ply weaves to increase the thread count. However, multi-ply inflation can result in pilling, shedding, tearing, and result in throwing the bedding away prematurely. Essentially, a high thread count does not always indicate a high level of quality.

Using more threads results in a tighter weave and a less airy pattern. Therefore, investing in a high thread count pair of bed sheets may not be the most ideal decision regarding breathability.

If keeping cool is your first objective, search for bed sheets thread count in the 180 to 400 range or sheets that never exceed 600 thread counts. Through this, you can be confident that your bedding will be comfortable and long-lasting while also allowing for consistent ventilation while you are sleeping.

Even though it is not realistic to pick an appropriate thread count without considering the fabric type, it is conceivable. In the same way that there is no such thing as the optimal thread count across the board, there is no such thing as a particular material that reigns supreme when it comes to bedding. Although some materials perform better as cooling bed sheets than others, it is not the sole determining factor on how cool your bed sheets can be.

High Thread Counts Trap More Heat

Getting up in the middle of the night due to night sweats can be a very unpleasant and disruptive experience. Even though increased temperatures during warm months can definitely be a major cause of it, some sleepers are predisposed to sleep hot all year round regardless. In order to avoid blasting the air conditioner all through the summer season, begin by paying greater attention to the structure of your bed sheet construction.

Here are the things to consider:

Avoid High Thread Counts

As a common association, higher thread counts (500 or above) indicate a higher quality; however, thread count nowadays informs us how many threads are in a sheet but it does not tell us anything about its overall durability or quality. On the other hand, the thread count has a significant impact on heat retention, with higher thread counts resulting in hotter sheets. 1000TC sheets are the warmest cotton sheets available on the market. Lower thread counts (250TC-350TC 10cm2), on the other hand, provide cooler sheets but they must be made of high-quality cotton to retain a premium standard.

High Thread Count sheets generally do not perform as well as lower thread count sheets on the aspect of breathability, which is why it can trap more heat and lead to your night sweats. A sheet that does not allow air to pass through it might trap heat and produce a heated microclimate beneath the blankets, which could increase bacteria proliferation.

Avoid Choosing Synthetics

Synthetic sheets are hotter, and many that look natural such as bamboo bed sheets for example, are manufactured from rayon which is a synthetic fibre produced from wood pulp as a base material. The same may be said for particular silk bedding sheets. Another point to mention is that modern synthetics like TENCEL™ fibres have been praised for their moisture-wicking qualities in recent years.

Ideal Thread Count For Cooling Bed Sheets

If you have to measure thread count for sheets, go for anything in the 400-600 thread count range, and look out for sheets that utilise single ply threads for a more breathable bed sheet.

Choosing cooling bed sheets with a thread count between 250 and 400 is ideal if you want to keep your body temperature down. Remember that the bed sheet thread count should never exceed 600 threads if you want the greatest cooling sheets. However, there are several more effective methods of selecting high-quality bedding than this.

First, you'll want to look into the materials that were used to make the fibres. Cotton sheets are likely the most comfortable and easiest to care for, both in terms of comfort and ease of cleaning. Cotton has been spun into sheeting for thousands of years for a variety of reasons, such as being soft and absorbent.

Following that, you'll want to select a weave method that feels comfortable to you. Sateen and percale weaves are the most commonly used types for cotton bed sheets. 

Check to verify if the fabric is composed of long-staple cotton, and then decide. The length of the individual cotton fibre spun together to form each thread is referred to as the thread length— cotton fibres that are longer provide stronger, smoother threads that tend to last longer.

Lastly, the most efficient approach to evaluate which bedding sheet is the best choice for you is to just sleep on it. Various weaves, density, and textures of sheeting appeal to various people in different ways. Additionally the fabric itself, aside from thread count, will reveal a great deal about the overall quality of the bed sheets, as some materials perform better as cooling agents than others.

Bed Sheet Materials to Stay Cool

Fabrics like cotton are the most popular since they are soft, breathable, moisture-wicking, and simple to care for. Currently, Egyptian cotton sheets, Pima cotton sheets, and Upland cotton sheets are the most common cotton sheets available. Depending on how long the staple or cotton fibre is, each of these types is classified from the others.

  • The best thread count for Egyptian cotton is between 400 and 700.
  • The best thread count for Supima or Pima is between 200 and 400.
  • The best thread count for upland cotton is between 300 and 600.

Moreover, the following are materials that are considered cooling bed sheets because they are naturally more breathable than others:

  • Cotton is constructed of natural fibres from cotton seed pods. Thousands of years of tradition employ this airy, breathable material.
  • Silk bedding effectively removes heat and moisture. Silk draws heat and moisture out from the body twice as quickly as cotton, resulting in a 50% reduction in humidity in your bed.
  • Satin creates a distinct tactile impression of softness and coolness. It feels cool on the skin and does not cling to overheated or moist skin.
  • TENCEL™ Lyocell is a soft fabric that has a sheen to it. TENCEL™ bed sheets are naturally cooling due to the inherent properties of eucalyptus pulp fibres. Moreover, TENCEL™ fibres are exceptionally absorbent, making them an excellent choice for hot sleepers.
  • Bamboo Rayon allows it to breathe better than other textiles and keeps it from clinging to the body in hot weather. It is an excellent fabric for athletic and summer outfits since it is soft and relaxed.


To summarise, we do not recommend bed sheets with high thread counts in hot and humid countries such as Singapore, as heat is easily trapped underneath due to the lack of breathability the fabric provides. It is also best to avoid synthetic fabrics for the same reason, and to select the fabric and relevant thread counts most suited for you in order to stay cool and dry.
