If you ever wake up feeling overheated and uncomfortable, you’re not alone. Sweating in your sleep is a common occurrence. There are different reasons why you might be running warm at night, from a poor sleep environment to toasty comforters. Some factors can be harder to control than others, but selecting the best cooling pajamas can help you stay dry and sleep comfortably.
At Eberjey, we prioritize comfort and quality in our sleepwear. We’re here to demystify night sweats and recommend the best fabrics for better sleep.
What Causes Night Sweats?
Our body temperature becomes lower at night to help us fall asleep. Sometimes, the temperature drops 1 to 2 degrees below normal daytime temperatures and fluctuates significantly throughout the night1. Despite that, it’s possible to “sleep hot.” Here are some common contributors to night sweats:
-
Beds and bedding: Heavy blankets and dense materials used in pillows and mattresses can trap heat, making you feel hotter. Avoid fleece, down, and memory foam to stay cool.
-
Temperature and humidity: Hot, humid rooms can affect your body’s ability to regulate temperature (aka thermoregulation), making it harder to fall asleep and stay asleep. The ideal room temperature for sleep is 65°F, with humidity kept below 60%2.
-
Physical activity: Any exercise that gets your heart rate up and makes you sweat will keep your body warm for a while. Avoid high-impact workouts close to bedtime.
-
Caffeine and alcohol: Consuming certain beverages before bed, especially those containing caffeine and alcohol, may cause you to feel warmer at night3.
-
Hormones: Hormone fluctuations from menstrual cycles, pregnancy, and menopause can lead to symptoms like night sweats.
-
Medication: Many common prescriptions, such as antidepressants and diabetes medications, might cause sweating and hot flashes.
-
Pajamas: Thick, insulating materials like wool and fleece are made to trap heat and aren’t very breathable.
How Cooling Pajamas Help Keep You Comfortable
Waking up feeling hot and sweaty isn’t just uncomfortable — it disrupts thermoregulation and may interfere with your circadian rhythm4. Night sweats often make it harder to get a full night of sleep, especially if you have trouble falling asleep or tend to wake up throughout the night. Poor sleep quality negatively impacts your physical and mental health, leading to problems like memory issues, difficulty concentrating, and a weakened immune system5.
There are several ways to improve your sleep habits to help keep night sweats at bay. For instance, wearing a better pair of pajamas will help increase your nighttime comfort and lead to more restful slumber. The best pajamas for night sweats are made from light, loose-fitting materials that are breathable, such as silk, cotton, linen, and Tencel.
Washable Silk
Washable Silk is a smooth, ultra-comfortable material that has been highly coveted throughout history — and for good reason. Our Inez Washable Silk collection is crafted from 100% mulberry silk, offering temperature regulation and year-round comfort, complete with a cozy feel. This material has excellent moisture-wicking properties, so even if you sweat, your pajamas keep you dry.
Cotton
Cotton pajamas are lightweight, breathable, and great for absorbing moisture — making it a popular fabric for sleepwear. It stands out for its moisture-absorbing capabilities and promoting air circulation, ensuring you stay dry and cool.
Linen
Linen is one of the most breathable fabrics. This quick-drying material absorbs and dissipates sweat, keeping you cool and sweat-free. Linen clothing can be on the stiff side, so it may not feel as cozy for some, but this helps prevent your pajamas from sticking to sweaty skin.
Tencel
Tencel isn’t as well-known as other pajama fabrics, but it’s an excellent choice for breathability. TENCEL™ modal fibers are responsibly sourced from wood, making the fabric sustainable, naturally absorbent, and highly durable.
When it comes to the best cooling pajamas for women, our iconic Gisele and Frida sleepwear collections are a top choice. Light, relaxed, and designed for comfort, these pajamas provide irresistible softness and restful sleep, free from night sweats.
When you shop with Eberjey, you know you’re getting soft, high-quality fabrics that make you look and feel your best. Browse our women’s pajamas and prepare for the ultimate nighttime comfort.
