Sleep used to be so simple: the body’s nightly slide into semi-consciousness, when the sun goes down and the work stops. Now, it’s a global industry that’s worth up to $40bn, according to consultants at McKinsey.
Keeping your pillow cold and other European sleeptech
Bedtech’s been an overnight success, with New York mattress firm Casper recently valued at $1.1 billion, six years after its launch in 2013. The field is expanding, though. Now we’re seeing cuddly sleep robots that breathe in time with you (Somnox); smart beds to stop you from snoring (Balluga); a ring that monitors your pulse and body temperature so that you can inspect your sleep data in charts when you wake up (Oura).
And the more we learn about our sleep, the more important it becomes. Studies now tell us that those precious eight hours protect us from a whole slew of dangers, from cardiovascular disease and car accidents to dementia and early death.
