Four foundations of better health
The SELF Principle is built on four evidence-based pillars.
Sleep
Sleep supports recovery, blood pressure regulation, appetite, and glucose control.
Exercise
Regular movement supports fitness, preserves muscle, and helps manage blood pressure and metabolic health.
Love
Supportive relationships, belonging, and purpose are associated with better health and well-being.
Food
Daily food choices shape blood pressure, blood sugar, weight, and kidney health.
