Has your doctor ever asked you to record any of your health parameters during your day? This comprehensive health journal can help you do just that. Each day, you can record your sleep, pulse (heart rate/rhythm), blood sugars, blood pressure, oxygen level, pain level, stress level, medications, what you ate, how you felt after you ate, your mental health status, and anything else your doctor asks you to record. Having a physical record of your health parameters can help you and your doctor track your health status.
