I’ve had the Ooler for a month now. It took me about a week to roughly dial in my temperature curve.
I had set it to the lowest temp all night which seems to be about 48F - didn’t sleep much that night, it was absolutely freezing, way too cold.
Now I have it set to be cool when I start my sleepy time, then within 2 hours it cools to freezing up to 4am, at which point it gradually warms.
It’s a game changer - the first few hours of my sleep is obviously deep-sleep, it’s like being in a coma. Pre-Ooler I would toss and turn constantly, looking for cool patches of the mattress - I did this all my adult life.
With the Ooler I have been waking up in a better mood, and completely refreshed. I noticed on a few days where I was sleep deprived due to having awoken up early - usually that day would be ruined for me from the outset, but now I have noticed that I am completely normal until evening at which point the lack of sleep becomes noticeable (this is normal for my lucky brother, not for me). I’ve put this down to good sleep banked.
Sweet spot has become easy, but honestly I don’t know if this is because I have not been following TR as much recently (and therefore am more rested), or started doing >ftp workouts after following SSB1&2, or because I adopted the Endurance diet (Matt Fitzgerald) 2.5 months ago.
It’s only been 4 weeks with the Ooler, let’s see how it goes.
