The Science of Sleep

Our bodies work on a circadian rhythm - we release hormones and activate certain functions in line with the 24-hour clock. Originally, humans would rise with the sun and return to sleep when it set. And, in order to get the best night's sleep, we still need to do this. Blue lights from screens and long working hours have thrown our ability to sink into restorative sleep with ease, which is why creating the perfect room for sleep is vital.


Light plays a key role in how well our bodies fall asleep. When we relax in a darkened room, our body releases melatonin - the sleep hormone. This signals to the body that it is time for rest and kick starts a chain of reactions that allows your body to restore and repair itself overnight. When this hormonal production is thrown out of synch, that’s when we experience sleep complications. 


Research has shown that a bedroom needs to be around 18 degrees for our bodies to start to cool down and slip into restorative mode. 

BlocOut Blinds control both temperature and light and therefore are the ultimate sleep-inducing blind.
