The sixth house is about physical efficiency. This is where your health, your work, and your desire to serve others all happily cohabitate together. You can think of this in terms of your day job or daily routine. It is also connected to your health and wellness, and the ways in which you take care of your physical body. These areas of your life might seem different from each other at first, but your health, your work ethic, and your helpfulness are all tied to what you find useful in the physical realm.
Signs and planets occupying this house can point to how you manage your schedule, organize your time, and attend to your day-to-day responsibilities. This house is associated with routines, and with how we handle the details of our lives. Say you have a whole squad of planets hanging out in the sixth house. In that case, you would be inclined to be a bit high-strung, but in a helpful way. Looking at what lies in your sixth house can help you understand how you handle the functional details of life.
