What is BMI ?
Body mass index (BMI) is a measure of body fat based on the ratio of an individual’s weight and height. BMI is calculated as the weight divided by the square of the height. A BMI for adult women and men between 18.5 and 24.9 is considered healthy. You should not use BMI as a measure if you’re pregnant. Definition of healthy body fat is more difficult to quantify for children, whose BMI changes with age. Get advice from your GP if you’re concerned about your weight.
What is RHR ?A healthy heart rate is an indicator of a healthy heart. Your resting heart rate (RHR) is a snapshot of how well your heart muscle is functioning. Various factors impact RHR, including stress, medications and even caffeine. A high RHR could be a sign of an infection or heart arrhythmia while a low RHR could signal fatigue or even bradycardia.
What is HRV ?Heart rate and HRV have a direct correlation to stress levels. Stress is triggered when a past event or recently upcoming event is overwhelming. The autonomic nervous system (ANS) affects the heart rhythm on a cellular level. The relaxation response tells your heart to slow down, increasing space for changes between beats (high HRV) and the stress response tells your heart to speed up, decreasing space for change (low HRV).
What is Salivary Cortisol ?Saliva is a thick, colorless, opalescent fluid and is composed of water, mucus, proteins, mineral salts and amylase. Our salivary glands secrete around 1-2 litres of saliva every day. Many of the compounds present in our blood enter saliva, making it a suitable tool to test the physiological health in terms of hormonal, nutritional and metabolic states. Stress can be determined in real-time based on cortisol measurements from saliva samples.
