To celebrate World Sleep Day, March 19th, we thought we'd take the opportunity to talk about why exactly organic cotton bedding is the best choice – not just from a sustainability stand-point, but also for a good night's sleep. Our organic cotton sheets, organic cotton duvet covers and organic cotton pillows are high quality, optimised for a healthy, comfortable, natural night's sleep. But what exactly is it about organic cotton bedding that will help you sleep better?
The Properties of Cotton That Make it Ideal for a Good Night's Sleep
Thread Count and Quality
Cotton is widely used in textiles, including bedding, due to the fact that it is the purest form of cellulose available in nature. The highest quality cotton varieties are those that have the longest fibres, which are thin, with good resistance and elasticity. These features make it easy to spin and allow high-quality textiles to be produced. Our luxury organic cotton bedding is made from the highest quality long staple 300 thread count cotton. It's top quality is obvious to the touch.
Looking at the properties of cotton fibres and fabrics and it becomes easy to see why it is a great choice for bedding. It is soft against the skin, hypoallergenic and won't cause issues for sensitive skin. Our bedding is made with percale and sateen weaves for exemplary comfort. It feels great against your skin, and many satisfied customers will testify to the fact that the comfortable skin feel of our organic cotton bedding helped them sleep better.
Another crucial property of cotton when it comes to getting a good night's sleep is its breathability. Polyester and other sheets made from synthetic materials don't let the air through, which can lead to a hot and sticky night.
Choosing breathable natural fabrics like cotton can therefore help you sleep better if you often find that you wake up in the night feeling all hot and sweaty. But cotton can also keep you comfortable if you tend to get too cold.
If you feel too warm, percale weave will be great for you. It is particularly useful as a fabric to keep you cool. Sateen sheets are great for winter, and have a silky smooth finish. These names refer to the ways in which the cotton is woven into a fabric.
The thermal environment is a key determinant of sleep. When we sleep, our bodies naturally cool. And thermal regulation can play an important role in sleep stages, and on the quality of our rest. Synthetic bedding can disrupt our body's thermal regulation, making it far more difficult to sleep successfully.
As a good heat conductor, cotton bedding helps combat overheating issues. However, it also lets less heat through than many other fabrics, so can also retain body heat on chilly nights. By helping to regulate the thermal environment, cotton sheets can help improve sleep and help prevent insomnia.
Cotton also has good moisture absorption properties in that it draws in moisture from the environment. This property means it wicks moisture away from the skin, helping you sleep well all night long.
In absorbing moisture, the thermal properties of the fabric change and cotton bedding, like other breathable, natural fabrics, delays external temperature changes and gives your body time to adjust to changing conditions during the night. 
Why Organic Cotton is Better
Unfortunately, while all cottons share the properties mentioned above, regular cotton is typically contaminated with pesticides and herbicides used when growing the crop. The toxicity of synthetic dyes often used on cotton are another source of concern. Many textiles are manufactured with harmful chemicals like banned Azo colourants, formaldehyde, pentachlorophenol, cadium, nickle, and lead.
The transmission of contaminants to the human body through the skin is a major worry. Several studies have explored the issue of transmission of contaminants from fabrics to skin. With bedding, it is worth noting the long time period you will spend in contact with the fabrics when making your choices. While the actual quantities of harmful substances are typically very low, they can become concerning when you consider the length of time of the exposure.
Choose certified, GOTS organic cotton bedding, however, and you can rest easier, without concerns about getting sick while you sleep.
You'll breathe easier too – without having to breath in the VOCs associated with other bedding options. Using toxin free organic bedding really can improve your health – and help you sleep better.
What is more, when you bed down on ethical cotton sheets, you will sleep easier knowing that you are not just doing what is right for you – you're also doing the right thing for people and planet. You can truly sleep the sleep of the just.
