In short, yes, a comforter can transform your sleeping experience. Sleep research has found that comforters provide us warmth during REM sleep as we can’t regulate body temperature during this time. Habits also form this attachment as we are conditioned to sleep with blankets from birth. There is also evidence to suggest that sleeping with a comforter or blanket can increase our serotonin (the happy hormone) and melatonin levels. A comforter specifically improves sleep quality with its weighted and hug-like comfort, as London-based interior designer, Shalini Misra shares. 'Selecting heavier bedding can elevate your sleep quality and even alleviate insomnia. Weighted blankets, for example, provide a comforting, cocoon-like sensation that encourages restfulness by limiting physical movement and aiding in uninterrupted sleep,' says Shalini Misra. To personalize your comforter and sleep experience, the choices are ever expanding, from lighter cooling varieties to warm weighted ones. It’s also common to swap comforters as the seasons change, tailoring your sleeping experience in the face of changing climates.
