Coffee is more than just a drink—it’s a ritual for millions of people around the world. Whether you savor that first cup in the quiet of morning or grab a to-go cup during your hectic day, coffee plays a significant role in many lifestyles. However, the question remains: can I leave my coffee maker on? While it may be tempting to keep your beloved machine running for convenience, several factors come into play before you make this decision.
