Uncover the hidden risks of mental exhaustion before it is too late.
Do you get mentally exhausted due to too much work or stress? Check your Workload Heart Rate to find out how it has impacted your heart.
When your heart works harder to meet physical demands, that effort strengthens the heart and improves health. But when it works harder to meet mental demands, most of that energy goes unused, leading to chronic, low-level inflammation — a key contributor to heart disease, stroke, diabetes, cancer, and other chronic diseases. Mental exhaustion keeps the heart mildly elevated for long periods, without the cleansing or strengthening benefits of exercise, causing long-term strain on your body.
Introducing Workload Heart Rate (WHR) — a new way to measure the extra load on your heart during mental effort. Lowering your resting heart rate by just one beat per minute can reduce your risk of premature death by up to 3%. Because your workload heart rate (the one you feel during mental load) has an even bigger impact, improving it could mean even greater health benefits.
CuesHub uses data collected by your Apple Watch and separates the load on your heart due to physical activity from that caused by mental activity, using proprietary biometric AI developed over 15 years of university research.
CuesHub personalizes to your physiology and sends relaxation nudges when you’re likely to overexert yourself if you continue at the same rate for the rest of the day. Use guided breathing or mindfulness exercises in the app — or your own favorite activity — to recharge.
You can maintain a healthy WHR by reducing exhaustion, improving sleep, increasing physical activity, and finding relaxation activities that truly work for you.
Connect your calendar to track the mental effort spent in each meeting. CuesHub lets you compare which entertainment options — reading, movies, sports, news, or social media — involve mental effort and which ones lead to real recharge.
