Do cooling blankets help with night sweats?


Night sweats can make you sweat a lot in your sleep, leaving your clothes and bed wet, which is uncomfortable. Sometimes, they might mean there's a health problem. This article talks about why night sweats happen and how using a cooling blanket might help, including how they work and some tips on picking and using one.

Night Sweats: Common Causes

Night sweats can be attributed to various factors:

  1. Hormonal Changes: Menopause, perimenopause, and andropause can lead to hormonal shifts, triggering hot flashes and night sweats.
  2. Medications: Certain drugs, such as antidepressants and diabetes medications, may list night sweats as a potential side effect.
  3. Infections: Fevers and sweating can accompany infections like tuberculosis, endocarditis, osteomyelitis, and HIV/AIDS.
  4. Cancers: Night sweats may be an early symptom of lymphomas, leukemias, and reproductive cancers.
  5. Other Conditions: Hyperthyroidism, hypoglycemia, and idiopathic hyperhidrosis are among the conditions that can cause excessive sweating.

If you experience frequent night sweats without an apparent cause, consult your doctor to explore potential underlying conditions requiring treatment.

Cooling Blankets: Technology Explained

Cooling blankets utilize temperature-regulating technology to dissipate body heat. Key approaches include:

  1. Phase Change Materials: These blankets incorporate gels or materials that absorb and store heat, pulling it away from your body as they transition from solid to liquid.
  2. Moisture-Wicking Fabrics: Utilizing materials like bamboo rayon or polyester, these blankets draw moisture away from your skin, promoting evaporation for a cooling effect.
  3. Temperature-Regulating Ceramic Powders: Some blankets include ceramic powders or beads that efficiently absorb and circulate heat, surpassing the effectiveness of fabric alone. This is the reason why some people prefer to sleep on top of a cooling blanket

This technology actively cools you, differing from regular blankets that primarily insulate heat. Using them is akin to having a personal air conditioner in your bed.

Cooling Blankets and Night Sweats: Alleged Benefits

This section reveals the potential benefits of cooling blankets as a promising solution for a more restful and comfortable night's sleep.

  1. Preventing Heat Build-up: By whisking away excess body heat, the blankets aim to prevent the onset of sweating.
  2. Accelerating Cooling: If sweating has already begun, the blankets claim to expedite the cooling process, reducing sweating sooner.
  3. Maintaining Dry Sheets: Through the prevention of heat build-up, these cooling blankets also aim to keep sheets and sleepwear dry.
  4. Enhancing Sleep Quality: Maintaining a comfortable temperature at night may contribute to deeper and more restorative sleep. This is the reason why many hot sleepers use cooling blankets

Selecting and Using Cooling Blankets: Key Tips

When considering a cooling blanket to combat night sweats, take into account these essential factors:

  1. Cooling Technology: Decide whether you prefer phase change materials, moisture-wicking fabrics, ceramic beads, or a combination.
  2. Size: Ensure the blanket is the right size for your bed, whether it's twin, queen, or king.
  3. Care Requirements: Confirm if the blanket is machine washable or requires special care.
  4. Price Range: Cooling blankets vary in price, from below $100 to several thousand dollars. Set a budget that works for you.

After purchasing a cooling blanket, it's essential to follow the manufacturer's guidelines for effective use and maintenance.

Optimizing Your Cooling Blanket Usage

For effective relief from night sweats using a cooling blanket, consider these tips:

  1. Create a Cool Bed Environment: Avoid using additional blankets or foam mattress toppers that trap heat.
  2. Ideal Room Temperature: Set your thermostat to around 65 Fahrenheit at night.
  3. Wear Suitable Pajamas: Opt for lightweight, moisture-wicking fabrics like bamboo rayon to complement the blanket's cooling effect.
  4. Positioning the Blanket: Place it under your fitted sheet for direct contact with the cooling surface.
  5. Pre-Chill the Blanket: For enhanced cooling, refrigerate or freeze the blanket for 1-2 hours before bed, if the model permits.

Finding the perfect setup might require experimentation, but these guidelines can significantly improve your chances of achieving comfort and relief.


In conclusion, cooling blankets seem to be a helpful solution for dealing with night sweats and making sleep more comfortable. Cooling blankets work by absorbing and getting rid of the extra body heat, providing relief throughout the night. Although more research could be done, the current science supporting these high-tech blankets looks promising.

If night sweats are bothering your sleep, trying out a cooling blanket, especially from reputable brands like pain-free-aussies, is worth considering. Just make sure to follow the recommendations on how to use and care for the blanket for the best results. With a bit of trial and error, you're likely to find a setup that brings you relief and makes your nights more enjoyable.
