I have found by using the sleep tracker that the colder the temperature that was down to 65 to 70 produced better sleep. More review coming

Last night was a great night for sleep. I slept 9.13 hours of good sleep. Still woke up twice to use the restroom but the overnight temperature dropped to 59 degrees. Here in Phoenix the overnight temperature in the summer is from 80 to 110.
