No matter how well you eat and exercise, it is crucial not to neglect the other crucial element to good health: sleep! Morning people and night owls alike should strive for quality daily shut-eye to achieve REM and wake up feeling rested... which is why a comfortable mattress is so important. Did you know you should replace yours approximately every 8-10 years? And if you're in the market for a new one, why not look for animal-friendly materials? Unfortunately, many contain wool, down, and even silk or cashmere, but there are many ethical options today that are still durable and breathable. They just won't tune out any snorers you share your bed with!
