Both of these metrics are of interest to athletes, but they have also been shown to be strongly associated with longentity. See Association of Cardiorespiratory Fitness With Long-term Mortality Among Adults Undergoing Exercise Treadmill Testing for more information.

Sleep Stage Tracking

Sleep is fundamental to your health and well-being. With CardioMood, you can track sleep stages, duration, and the quality of your nightly rest. Sleep allows your brain to consolidate memories and remove toxins from the body while regulating metabolism and protecting your immune system. It’s no exaggeration to say that sleep is the most important pillar of overall health. 

Sleep Need

CardioMood guides you on the best time to go to sleep based on your chosen wake up time. You can adjust the required sleep goal based on the expected demands for the next day or if you feel you need to catch up on sleep debt. From a circadian biology perspective, your day begins when you go to sleep each evening. Sleep allows the human body to recover from the physical and mental demands of the day. So do not guess how much time you sleep, measure it with CardioMood.

Readiness Score

CardioMood collects data throughout the night that is used to calculate your Readiness Score. Your Resting Heart Rate and Heart Rate Variability (provide a link to deeper content, studies) are the primary metrics used to create this score. Deviations in your temperature will come into play if the variation is significant. You can view the trends for this score on the CardioMood mobile app. Also, your Readiness Score is personal to you. We compare your short term trends against your long term baseline. This method is based on years of sports research and is well established in the health and wellness community.

Heart Rate Variability (HRV)

At the core of CardioMood is a modern heart rate variability methodology, actively used throughout the world. With the help of advanced algorithms developed by us, we give you the most customised and personalised advice to ensure you’re ready for your next challenge.
