Whoop Not Detecting Naps? Here’s What You Need to Know

by | Sep 19, 2023

If you’re a WHOOP user like me, you understand how crucial the device can be for tracking your health metrics—especially sleep.

But what happens when your WHOOP is not detecting naps?

It can be incredibly frustrating and defeat the whole purpose of having a smart health tracker.

So, let’s dig into this issue, understand why it happens, and explore solutions.

Why Is WHOOP Not Detecting Naps?

There are several reasons why WHOOP may not detect your naps. Here are some of them:

  • Software glitches – Updates or software issues can sometimes affect the device’s ability to track naps. Always ensure your Whoop is updated to the latest firmware.
  • Improper fit – If the band is too loose or too tight, this could affect the sensor’s ability to monitor your sleep metrics effectively.

It’s important to know that this is a common issue that WHOOP users experience. For some reason that is unknown, WHOOP commonly fails to detect naps or sleep.

Note: If you are still in your initial 30-day window of using your WHOOP, give it some more time to calibrate. WHOOP states that it can take up to 30 days for your strap to fully calibrate to you, which can help it auto-detect naps more accurately. Over time, it will get better at detecting naps.

How to Fix WHOOP Not Detecting Naps

If  your WHOOP isn’t detecting naps, follow these steps:

1. Check The Band Fit

If your band is not being worn properly, it can result in your activities, such as a nap, not being recorded fully, or at all.

Make sure the WHOOP strap is snug to your wrist to prevent it from sliding around, but it shouldn’t be so tight where it’s indenting into your skin.

2. Restart the WHOOP

Have you tried turning it off and back on again?

In al seriousness, software glitches can often be resolved by a simple restart. Follow our guide on how to restart your WHOOP strap.

3. Update the Software

On occasion, improper or failed readings can be due to out-of-date software. While this is unlikely the case, it is a valid troubleshooting step.

4. Manually Add a Nap

What you’ll likely end up having to do is manually add a nap to your WHOOP. It’s unfortunate that it must be done this way because it requires extra work every single time it fails to auto-detect a nap, but, until WHOOP fixes the issue, it’s the best option.
