New OHR sensor design causing skin issues

Had the same now and then. With all watches
Same here. I can loose strap so it moves on my hand all the time a bit but still marks on hand just like original poster here. Years passed and no any serious problems with my hand. I sometimes put my watch on right hand when go sleep, and next day left is like 90% recovered
-
No issue here. Outside of activitty i wear it loose. Never had marks like on your pictures. Even after activity when i have watch tight.
-
@Alex-Jurkiewicz @Dimitrios-Kanellopoulos I am leaving it to heal for now. Interesting is that it started just recently. Today I had the watch on on my right hand just for a 30 min exercise and I had red marks, and it was not tight. Starting to think that I have developed an allergy.
-
@OutdoorMan did your previouse watch was made out of different material type?
-
@OutdoorMan contact dermatitis is not an allergy. You can speak to your GP for more info, it’s reasonably common
-
@OutdoorMan Unfortunately the best thing to do to heal from contact dermatitis is to just stop wearing any wearables for a couple days until it heals.

Internet says: Contact dermatitis is an itchy rash caused by direct contact with a substance or an allergic reaction to it.

@strain Yes this is what I am doing. I just hope it won’t return straight away.

Maybe the permanent light from the LEDs bringing some irritation to the skin? Sometimes I think that the light shining 24/7 on it isn’t really a healthy situation. I wish Suunto give us the option to turn back to former 10-minute-readings.
-
@jschmidt at least during night it is not permanent, it measures in some time inteval, not sure how long. But does it really measure during day all time? I would really prefer measurement only every 5 or 10 minutes, in same way as apple watch does it.

i would doubt that the photons from the green LEDs have enough energy to ionise electrons in your skin cells to do any harm on a molecular level. Especially compared to UV light from the sun which you are getting in way higher doses when being outside.
-
@ChrisA for ionisating radiation you need much diffferen spectrum, but electromagnetic radiation goes rapidly down with distance. So intensity of led that is in contact with skin can be much higher than intensity from distant light sources even when this distant sources are much more powerfull. So mybe someone with higher light sensitivity can have issues with that. Consider even that that you are on direct sun few hours per day but this sensor shines 24/7 and doesn’t give cells any time to rest. I believe there are some studies done in this topic. But in profit driven economy you can never trust it. Just time will tell.
But this case is more likely some iritation of skin from not enough fresh air, higher mhumidity etc.
-
@Tomas5 yeah I know about the different frequencies, but even with considering 24/7 usage I doubt the energy transmitted is high enough to cause any harm. I could imagine though, that very sensitive people could show some reactions, but Inwould guess they’d rather look like a skin darkening and not some kind of rashes or inflammation.
-
@Tomas5 I have a 9PP and I‘m really sure that this watch does the reading permanently. I remember that Suunto changed the reading from 10 (or 12?) minutes to all the time with the introduction of nightly HRV measurements. I guess that this was necessary due to reliability of the data.
-
@jschmidt how does that impact battery ? With option to measure every 10minutes, would we have much better battery life?
