Why Do My Sheets Make Me Sweat?

There's little more disturbing than a bad night's sleep. One common concern many have is, why do my sheets make me sweat? It's a valid question and one that can be influenced by various factors.

From the type of material used in your sheets to your body's natural temperature regulation, there's a lot to unpack. But don't worry, we're here to guide you through it.

Let's explore the reasons behind those sweaty nights and how you can achieve the restful sleep you deserve.

What this article covers:

What Causes Night Sweats?

Night sweats, the uncomfortable phenomenon of waking up drenched in sweat, can be attributed to a variety of causes. Here are a few, based on our observations:

Medical Conditions

Numerous medical conditions can trigger night sweats. Infections can cause the body to sweat excessively during sleep. Thyroid problems, particularly hyperthyroidism, can elevate the body's metabolic rate, leading to increased body temperature and sweating.

Additionally, certain types of cancers and conditions like hypoglycemia can also manifest as night sweats.


Menopause is a significant phase in a woman's life marked by the end of her menstrual cycles. One of the hallmark symptoms of menopause is hot flashes, which are sudden feelings of warmth, usually most intense over the face, neck, and chest.

These hot flashes can occur during the day or night. When they happen at night, they're often accompanied by sweating, leading to what's commonly referred to as "night sweats."

Hormonal fluctuations and the decline in estrogen are responsible for these temperature changes.


Alcohol has a multifaceted impact on the body. While it might initially feel like it's warming you up, alcohol actually dilates the blood vessels, leading to rapid heat loss.

This, combined with alcohol's diuretic properties, can lead to dehydration, making the body work harder to cool down, often resulting in night sweats.

Stress And Anxiety

The link between the mind and body is profound. When an individual experiences high levels of stress or anxiety, the body responds by releasing stress hormones like cortisol.

This release can lead to an increased heart rate and elevated body temperature. Over time, chronic stress or anxiety can disrupt the body's natural temperature regulation processes, leading to night sweats.


Your choice of bedding can be a significant factor in how you experience night sweats. The materials, weave, and even the type of mattress play a role in temperature regulation during sleep.

Additionally, the type of blankets, comforters, and mattresses you use can either retain or dissipate heat. For instance, memory foam mattresses are known for heat retention, while lightweight quilts can help keep you cool.

Why Polyester and Microfiber Sheets Worsen Night Sweats

Our research indicates that polyester and microfiber sheets often exacerbate night sweats because both are synthetic materials. Unlike natural fibers, these synthetic materials are not as breathable. They tend to trap heat and moisture against the skin, preventing effective evaporation of sweat.

Consequently, this trapped moisture can make you feel clammy and uncomfortable, leading to disrupted sleep.

Bed Sheets to Keep You Cool Throughout the Night

The right choice of bed sheets can make a world of difference in regulating your body temperature during sleep. While many factors contribute to a comfortable night's rest, the material and weave of your sheets play a pivotal role in ensuring you stay cool and sweat-free.

Let's explore some options that can help you achieve a dry night's sleep:

Bamboo Sheets

Bamboo sheets have gained popularity in recent years, and for good reason. Derived from the bamboo plant, these sheets offer a unique combination of benefits that can help combat night sweats.

Bamboo fibers are naturally breathable. This means they allow for efficient air circulation, helping to regulate body temperature throughout the night. This breathability ensures that heat doesn't get trapped between your body and the sheet, reducing the chances of sweating.

Furthermore, bamboo sheets excel in wicking away moisture. If you do sweat, these sheets move sweat to the outer layer and evaporate the moisture faster than many other materials, keeping you dry and comfortable. This is especially helpful if you share your bed with snuggly pets, making them some of the best bed sheets for dog owners and best bed sheets for cat owners.

As an additional benefit, bamboo is a sustainable resource. It grows rapidly and doesn't require pesticides or herbicides to thrive. This means that, in addition to their cooling properties, bamboo sheets are also an eco-friendly choice for your bedding.

Percale Sheets

When it comes to a solution for night sweats, percale sheets emerge as a top choice.

They are woven in a one-over, one-under pattern, which gives them their signature crisp feel. Our findings show that this unique weave promotes better air circulation, ensuring that heat doesn't get trapped between the sheet and your body.

Percale sheets, typically made from cotton, are breathable. This breathability ensures that any moisture or sweat is efficiently dissipated, keeping you dry and comfortable throughout the night.

Percale sheets are also known for their longevity. The tight weave ensures that the sheets withstand regular wear and tear, making them a worthy investment for those seeking both comfort and durability.

Frequently Asked Questions

When it comes to night sweats and bedding, many questions arise. Here are some common queries:

How Often Should I Wash My Cooling Bed Sheets?

It's recommended to wash your sheets once a week. Regular washing ensures that the sheets remain fresh and free from sweat or body oils. Avoiding harsh detergents and following care labels can help maintain the sheet, making them last longer than they might otherwise.

Do Cooling Sheets Work With Mattresses That Have Cooling Technology?

Yes, cooling sheets complement mattresses with cooling technology. If you have a high-quality mattress designed with cooling in mind, using cooling sheets will enhance its performance, ensuring you get the best sleep possible.


Understanding why your sheets make you sweat is essential for achieving a restful night's sleep. We've explored various factors that contribute to night sweats, including medical conditions, menopause, alcohol consumption, stress, anxiety, and most notably, your choice of bedding.

Your bedding materials, weave, and mattress type significantly impact temperature regulation during sleep. Polyester and microfiber sheets, due to their synthetic nature, tend to trap heat and moisture, making night sweats worse.
