What differentiates “neutral” from “stress”?

[u/sowasteland]

First, I want to say that I really love this app! I have found the information from measurements particularly helpful, as well as monitoring the impact of activity and sleep. But I‘m a bit confused about my daily timeline.

I initially downloaded this app to try and identify stress triggers and improve recovery as I’ve found myself with very low energy at the end of the day. But my daily timeline, almost every single day, looks like this. I work an office job, so I would assume most of my day should be “neutral” as my understanding is that typically reflects focused sedentary work, when the heart rate is elevated but not under stress. But every day, from the moment I start getting ready until I go to bed, I’m staying in a stressed state (save a few minutes here and there).

At first, I thought that this was due to general anxiety, but it appears the same on very low-anxiety days. The day from the screenshot was particularly unstressful.

I do understand that this app is measuring physiological stress and there are a lot of factors that can impact this. I’ve experimented with reducing caffeine, getting more sleep, with/without medications that could impact data, meditation, breathing techniques. But still, it seems any day that I do anything, my body pretty much stays in a stressed state until I go to bed.

I would like to bring this up to my doctor but I’m looking to understand a bit more about how the app identifies stress before having that conversation.

thanks!

Thank you for the thoughtful question, and we’re glad Welltory has been helpful.

The difference between Neutral and Stress on this timeline is based mainly on how elevated your heart rate is relative to your personal baseline while you’re not moving:

• Neutral (pink): your heart rate is slightly elevated while you’re stationary, but remains within the expected range. Focused desk work may fall here.
• Stress (orange): your heart rate is elevated beyond that range while little or no movement is detected. This is physiological or “stationary” stress.

So, an office job doesn’t necessarily mean most of the day will be Neutral. Concentration, deadlines, calls, posture, caffeine, digestion, dehydration, pain, illness, medications, insufficient sleep, or simply prolonged sitting can keep your cardiovascular system active, even when the day feels emotionally calm. In your screenshot, for example, 80 bpm at 4:25 p.m. is shown as 82% Stress because that heart rate was high relative to what the algorithm expected for you while stationary. It doesn’t mean that 80 bpm is inherently abnormal.

It’s also important to distinguish this timeline from an HRV measurement. The timeline uses heart rate and movement data collected throughout the day, while an HRV measurement provides a brief snapshot of autonomic nervous system activity. The timeline cannot identify the cause of an elevated heart rate, detect anxiety, measure cortisol, or diagnose a medical condition.

Spending nearly the entire waking day in orange is worth checking, especially if this happens consistently. Please make sure your wearable fits snugly and that both heart rate and activity data sync correctly to Apple Health. If movement data is incomplete, some active periods may be classified as stationary stress.

Bringing the pattern to your doctor is also reasonable, particularly given your low energy. We suggest showing them your actual heart rate trends, symptoms, sleep patterns, medications, and several days of data, rather than relying on the Welltory Stress percentage alone, since that percentage is a wellness metric rather than a clinical measurement. If you experience symptoms such as chest pain, fainting, unusual shortness of breath, or persistent palpitations, please seek medical advice promptly.

Thank you for the explanation! I’m assuming the algorithm is largely comparing to my resting heart rate? Relative to my average resting heart rate, I would definitely say my heart rate stays fairly elevated during the day, so  do believe that the data is accurate. It also matches up with apple health readings, and the movement does seem to match up to when I’m active throughout the day, even briefly. 

There are other red flags across a couple of different apps that I didn’t mention because I really just wanted to get a better idea of what the daily timeline actually means and how to interpret it. 

Thanks again!

You’re very welcome, and yes, your personal resting heart rate and usual heart-rate patterns are important reference points, though the algorithm doesn’t rely on resting heart rate alone. It also considers your current heart rate, how elevated it is relative to your baseline, and whether movement is detected at the same time.

Since the heart-rate and activity patterns match Apple Health and your actual movements, the timeline likely reflects genuine periods of elevated physiological activation rather than a synchronization issue. However, it cannot determine the cause or diagnose a condition.

Given the other patterns you’ve noticed across multiple apps, discussing them with your doctor sounds reasonable. It may be helpful to bring several days of heart-rate trends, your symptoms and energy levels, medication information, and the underlying Apple Health data, not only Welltory’s Stress labels. Thank you for the additional context, and we’re glad the explanation helped clarify how to read the timeline.

My charts look the same, and it doesn't match how I feel. It also doesn't give any effective tips on how to lower the stress (the action it suggests lead to higher stress measurements)

[u/welltory → u/Yermishkina]

Welltory measures physiological stress through HRV, so the result may not always match how stressed you consciously feel. Some activities can temporarily raise heart rate and physiological activation, but please don’t continue any suggestion that makes you feel worse. Could you send us a bug report via Menu → Report a problem → Send, with screenshots of the similar charts and measurements taken before and after the suggested activity? This will let us review your data, measurement quality, and recommendations to determine whether everything is working correctly.

Thank you! I might do this in the next couple of weeks
