I’ve been using my Aha Halo for several months now, and I’ve been tracking certain metrics with my Apple Watch and Oura ring. On the nights that I forget to bring my halo to bed, my sleep metrics drastically change. This is not something that psychosomatic. When I forgot to bring it with me to bed, I don’t realize it until the next morning. I will see it when I get up where it’s usually sitting charging. That’s when I look at my sleep metrics and realize that there’s a severe deficit to back up my feeling of fatigue. Although I enjoy using my halo for a lot of different things, I feel like it’s worth the purchase price for sleep alone!

What sleep program do you use
I’m using Sleep III, but as I understand it the programs are different for each person. I would recommend trying each one until you find which one works best for you.

I totally agree - especially the peptide-version. I have a 7 year old son who woke up every night between 3 - 5 times and I had to wake up too. The regular sleep programme (no. 1) improved this but the effect of the peptide-version is unbelievable: after one week using it he wakes up only once a night to go to the toilet. It is a great improvement of my life and sleep quality.

Dear Antithesis, I am curious as what specific metrics or areas you found the deficit(s) that explained the fatigue. Would you be so kind to share more details, please?
The metrics that explain it are duration of sleep (the obvious one), amount of deep sleep, and amount of REM sleep. For me, 7:30 minutes of sleep at least with over 1 hour of deep and 2 hours of REM sleep is my sweet spot. When I don’t use my halo, I get as little as 30 minutes of deep sleep, and 1:15 hours of REM sleep.
As a sort of corrolary to this: Over the part year I’ve had 2 or 3 occasions where I forgot to change the program from a Sleep program to something else for the day time, and each time I couldn’t figure out why I was so tired and couldn’t get going! 
Every time, it was that I forgot to change the Halo program.

I only see Deep Sleep in my program, there is no other one, has that changed?
In the current Aha Halo program library, there is Good Sleep (P) and also Good Sleep 1, 2, 3 in the regular program library. There is no program named “Deep Sleep”.
Could you please share a screenshot of what you’re seeing?

Thanks for the reply. I wrote it wrong, I see Good Sleep(P) and now I realize that I completely forgot about the other part (regular program), which is only visible when you click on it in the menu 
I use an Aura ring to track sleep metrics.
I use Loud Sleep (P) every night. I have asthma, and it helps my breathing while I’m sleeping.
It’s still listed in the most recently available Program Descriptions (2026-4-13) on ahaharmony.com, but it has not been mentioned in this thread. Has it been discontinued?
No, Loud Sleep (P) has not been discontinued. It is still an available Aha Halo program.
We’re glad to hear it feels supportive for your nighttime breathing.
