Ever thought about what’s actually inside your mattress? Sleep doc Eduard Estivill says if we could see it, we’d run away! He’s all about swapping your mattress every 5 years—no excuses. Turns out, a fresh, medium-firm mattress isn’t just for comfort; it can help with back pain, better sleep, and even deeper rest. Estivill says it’s totally worth the investment (like, a euro a day!). Time to rethink that old bed? #Health #BodyHealth #SleepHealth
