Along with air and moisture, cleanliness plays a major role in home health. This does not mean obsessively scrubbing every corner. Instead, it means building a realistic routine that keeps your home reasonably clean and safe. A healthy cleaning routine focuses on high-touch areas such as doorknobs, kitchen counters, light switches, remote controls, and bathroom surfaces. These are the places where germs are most likely to collect, especially in homes with children or frequent visitors.
