Same. Son and I walk 3-5mi at night. Upper 80s and 90% humidity is preferable to daytime. Many fewer opportunities to be mowed down is a plus.
FWIW: I had insomnia for years before eve exercising. Sleep is improved, some.
I don't disagree with this but even walking 4mph @ 87°dewpoint = ⅔ soaked, which feels not gentle. Actual intense exercise in that mug might kill us however.
>A moderate-to-intense run in the evening does affect my sleep, though.
Oddly, I've used short strenuous workouts to combat severe insomnia. More pain is better. It helps when panic is the driver but not for sleep=broken events.
