The cooling sleep aid for hot sleepers

Did you know that 1 in 4 people tend to overheat at night? If our body struggles to lower its temperature and keep it low, we will not only sleep less, our sleep quality will suffer as well. Find out how Dagsmejan’s cooling pyjamas can help!


Did you know that 1 in 4 people tend to overheat at night? However, “thermoregulation is key for a good night’s sleep,” as Dr med. Lutz Graumann explains. “To fall asleep and enjoy deep, restorative sleep, we need our core body temperature to drop.”

If your body struggles to lower its temperature and keep it low, you will not only sleep less, your sleep quality will suffer as well. As a consequence, you will not wake up feeling as rested as you need and deserve.

One simple yet effective solution is investing in the right bedding and pyjamas for hot sleepers.


Hot sleepers face two main issues: firstly, during the night, their rising body temperature will shorten their deep sleep phases. However, these phases are essential for our nightly regeneration, as it is only during deep sleep that we produce certain hormones that trigger the restoration of the cells throughout our body, including our brain.

Secondly, hot sleepers might begin to sweat, which can quickly soak fabrics such as cotton, leading to a damp feeling on the skin. If the materials in contact with our skin do not dry quickly, we might start to shiver, and that can eventually wake us up.



Both issues can be remedied by choosing the right fabrics for your bedding and sleepwear. Since some fabrics can trap in heat, it is important to choose breathable materials – all year round. Often, when thinking about breathable fabrics, cotton comes to mind. While it is an amazing natural fibre, that old cotton t-shirt you love so much might not be the best choice for a good night’s sleep.

The same is true for our bedding. Heavy or synthetic fibres will not help our body regulate its own temperature and might hinder our sleep. So, when looking for the best sleepwear and bedding, be sure to choose breathable, lightweight fibres with the best possible moisture and temperature management.

Dagsmejan offers cooling sleepwear that will support your body in lowering its core temperature to make sure you get a good night’s rest. Our Stay Cool collection…

…is 8x more breathable than cotton

releases water vapour 60% better than cotton

dries in 1/3 of the time

The secret behind our ultra-light cooling nightwear is botanic fibres derived from eucalyptus combined with the latest textile technologies to keep you cool while sleeping.

Dagsmejan’s innovative NATTCOOLTM fabric combines maximum breathability with a dual moisture management approach. Excess body heat is released through the fabric, which also draws sweat away from your skin to keep you dry, while using the excess moisture to create an evaporative cooling effect to further cool you down. 


As technical and functional as all this might sound, Dagsmejan remains an all-natural solution using no synthetic fabrics, only renewable, environmentally friendly fibres such as beechwood and eucalyptus. Thanks to the latest textile technology, Dagsmejan’s one-of-a-kind material mix keeps your body in its ideal thermal comfort zone all night long.

All the natural fibres that Dagsmejan uses in its sleepwear also come from sustainable sources, such as natural forests and sustainably managed plantations in Europe. All production processes, from spinning and bleaching to knitting and dyeing, are certified to OEKO-TEX® STANDARD 100, which means that the textiles are free from harmful substances. To ensure that all workers have fair working conditions, production is carried out according to the standards issued by the BSCI (Business Social Compliance Initiative).

And last but not least, Dagsmejan packaging is 100% recyclable and uses hygienic biodegradable poly bags. Also, don’t worry if you wish to return a product: we offer free returns, and all items that are returned unused are re-steamed and re-sold to minimise waste. For peace of mind and an even better night’s sleep.
