Why do we use a blanket while we sleep?
The most obvious reason is to keep ourselves warm. Yet, when we step outside, we use coats, sweaters and jackets. Why don’t we sleep in one such garment?
Look even further, and you realize how people in warmer climates also use blankets. They crank up the fan or the air-conditioning and bundle up in bed despite the temperature being 40 degrees Celsius. Blankets make us feel ‘snug’ and ‘cozy’ – words that convey more than merely warmth.
A kernel of mystery is hidden even in the most banal situations, if you are willing to look for it.
