If your body is managing inflammation well, HRV will not be as profoundly influenced. During the first couple of days of using the new WHOOP strap, I noticed that the battery would drain within a day or two. The WHOOP 4.0 features an optical heart rate sensor with green LEDs that shine light through the blood vessels underneath your skin and four photodiodes that collect the reflected light. One of the most useful features of WHOOPs recovery tracking is the WHOOP Journal, because it enables you to answer a few questions every morning (about lifestyle choices and medical conditions) that WHOOP can then correlate with changes in your recovery and sleep scores. Heart rate variability (HRV) is the difference in timing between heart beats expressed in milliseconds and a proxy of the balance between your sympathetic and parasympathetic nervous systems. The technology behind WHOOPs HR sensor is called photoplethysmography (PPG), and it enables WHOOP to measure your heart rate and heart rate variability. I dont rely on it to know my caloric output at all. Hard to know without a basic meter. Depending on my recovery percentage, WHOOP suggests my optimal strain for that day to prevent over-training and to lower the risk of injury. It shouldnt be surprising that EEG-based monitoring is relatively accurate, especially when paired with additional (wrist-worn) sensors. Idk man i burn like 4000 a day. I referred to heart rate during exercise and the corresponding algorithm results for calories burned, HRV, strain etc. I have the same issue! Based on https://www.federalregister.gov/documents/2020/12/14/2020-26342/notice-of-issuance-of-final-determination-concerning-a-whoop-strap-device, the hardware is manufactured in China (no surprise there) but programming takes place in the U.S. Do you have any idea if hrv works well if I have an irregular heart beat not afib?

It provides no native support for detailed sleep tracking (not even in the Apple Watch. Ill get my biceps band next week, so I should have some feedback on it soon. WHOOP is an excellent tool to help you understand the secrets your body is trying to tell you, and Ive used it for almost three years to improve my overall health, sleep patterns and stress levels. I would not recommend the Whoop. The Apple Watch series 4 or 5 have battery life long enough for sleep tracking and with a fast charger can get you from 25% to 80% in 15 minutes, enough to fit into a shower routine. I love new wearable tech and try most platforms and ultimately think it will become very reliable and significant to healthcare. My recommendation would be to read up on the latest scientific evidence and to ask your sleep coach what studies he bases his opinion on. WHOOPs straps have come a long way since the WHOOP 2.0. Specifically, the new WHOOP Strap now includes red and infrared LEDs and additional photodiodes to penetrate the skin deeper and to differentiate between oxygenated and non-oxygenated hemoglobin.

If I want really good data in the pool, Polar Beat with OH1 on my temple in memory mode does the trick and I just accept Whoop for what it is. WHOOP measures your daily accumulated strain score using a scale from 0 to 21: Note that WHOOP calculates strain from your max heart rate, which means the score is highly personalized. Take a day off training or do a low-strain routine. WHOOP automatically tracks your resting heart rate (RHR) as well as your heart-rate variability (HRV). In other words, the device can tell you how hard your cardiovascular system worked on a given day. Increasing weight and adding new strength exercises to your routine will likely cause soreness and muscle fatigue, otherwise known as delayed onset of muscle soreness (DOMS). We've found that when WHOOP members report consuming alcohol, their HRV drops by an average of 22 milliseconds the next day and can suppress your heart rate variability for 4-5 days. Good question! If it cant measure heart rate accurately, then how can I trust any of the other measurements? Thats where WHOOP can help. Maybe its only an option for existing lifetime members. While that doesn't change my editorial integrity, it helps make this blog happen. Custom WHOOP Journal entries would also be nice to have. The Apple Watch can.

For example, if your current strain score is 5.0 and then you go for a run that clocks in at 10.0, your total strain score is likely lower than the sum of both (15.0). But dont be fooled by WHOOPs simplicity! For example, if you drink a glass of water, your HRV might change in response.

From missing nights data to not recognizing activities, and an inability to correctly record sleep (even after manually updating it to correlate to my other devices). Thats leaving aside the very well known, widely acknowledged biological effects of light (including electrical sources of visible light, visible sunlight, and non-visible frequencies like UV and IR) which are technically EMFs, but we dont usually include those in the discussion. Appears there might be some accuracy deficiencies that no product has resolved. However, recently have been feeling very tired and thought the whoop maybe a good tool to have.

Also, you might find this article interesting for your journey towards a healthier life: https://michaelkummer.com/health/healthy-lifestyle-guide/. I found another study that outlined the accuracy of various monitoring devices, including electroencephalography (EEG), skin conductance (SC), skin temperature (ST) and accelerometers (ACC). For example, heres a paper showing that industry funding in wireless safety studies significantly influences outcomes, in the favor of showing wireless is safer compared to independent studies: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1797826/.
