Consider this: you spend about one-third of your life asleep. It makes sense that all this time spent in just a few of your most comfortable or habitual sleep postures would greatly influence health and wellbeing. 

You may ask if it really matters what you sleep on every night. Well, all those many hours of sleep add up to around 26 years. That's a long time spent pressing the delicate skin on your face into a cotton pillowcase. Those of us in the Hyoumankind team who have switched to silk are sold on its benefits for our skin and hair (especially those of us prone to frizz).
