I’m an emergency nurse and a mum of two, so you might be able to imagine that I have a lot on my plate. Because of that, I don’t really have as much time as I’d like to focus on other important things like my own health or fitness. So, when I saw Mark’s video about the Ultrahuman Ring Air, I was instantly interested.

Because of my job, my days (and nights) are busy, physical, and unpredictable. I’m constantly on my feet, washing my hands, wearing gloves, cleaning, and juggling work with family life. I wanted a fitness tracker that could fit into my life without being bulky or getting in the way, so I gave the Ring Air a go and, after three months of use, it certainly fits the bill. Here’s what I found out!

Comfort and wear at work
As a nurse, we have to follow bare below the elbow uniform policy, which means watches and wrist wearables aren’t an option at work. This is where the ring really stood out; it was much more discreet and allowed me to track my health without breaking uniform rules.

The ring is lightweight and comfortable enough to wear through long, demanding emergency shifts. It didn’t interfere with PPE, gloves, or constant hand hygiene, and I often forgot I was wearing it, which is exactly what you want during a hectic shift.
Fit and durability
After losing weight, I noticed the ring became looser and started to rotate more, especially during long shifts and frequent handwashing. This also seemed to affect connectivity and tracking accuracy, so the ring wasn’t quite as precise as it was when it fit snugly.

Because of this, I’d strongly recommend adding the warranty add-on, which allows Ultrahuman to replace the ring if your size changes. If you’re actively losing weight or expect body changes, this makes the purchase feel much more secure and worthwhile.

As a mum, I do a lot of cleaning — wiping surfaces, washing dishes, general day-to-day housework — and I did notice that the silver version of the ring scratches over time. It doesn’t affect performance, but cosmetically, it does show wear if you’re using your hands a lot both at work and at home.
Keeping up with the Mum Life
With wake-ups during the night for a baby, I was genuinely impressed by how accurate the sleep tracking was. It consistently picked up when I was awake and resettling, which really helped me understand how broken sleep was affecting my recovery and energy levels, something I found incredibly useful alongside demanding emergency shifts.

The ring also provides cycle tracking and temperature insights, which I found very helpful for understanding my hormonal patterns and overall body changes. While these features are optional and require a paid add-on, they give an extra layer of insight into wellness and recovery, which I appreciated as a woman balancing work, family, and fitness goals.
Motivation and Cardio Age
The biggest positive for me has been the motivation boost. Seeing my recovery, readiness, and especially cardio age pushed me to do more. I started running further and being more consistent, and it genuinely paid off; my cardio age has gone from 39 down to 30, which is actually younger than my real age. That’s been a huge confidence boost and kept me focused on improving my fitness.
No mandatory subscription
One thing I really appreciate is that there’s no mandatory subscription. You get access to your core data and insights without having to pay a monthly fee, which was important to me as a mum. It makes the ring feel like a one-off investment rather than another ongoing cost, especially compared to other wearables that lock features behind subscriptions.

Final thoughts
The Ultrahuman Ring Air has worked really well for me as a wellness and motivation tool, especially for sleep, recovery, and long-term health insights. It’s comfortable for long nursing shifts, discreet enough to meet bare below the elbow requirements, and easy to wear day and night. It’s not perfect, scratches can happen, fit changes can affect accuracy, and some features are add-ons, but with the warranty bolted on, it’s been a hugely positive investment in myself.
As an emergency nurse and mum of two, I’ve found it genuinely helpful for understanding my body better, staying motivated, and keeping track of my overall wellness, even with a hectic schedule.
