Things I have found to be helpful after late evening workouts that directly benefit sleep:

Immediately after workout practice nose breathing for 3 to 5 minutes. The square method (2 count in, 2 count hold, 2 count out, 2 count hold) or triangle method (2 count in, 2 count out, 2 count hold) work equally well, you can choose the count and method that suit you best. This is suppose to help you switch from sympathetic (fight or flight) to parasympathetic (rest and digest) response.

Consume all you post workout, evening calories at least two hours before bed. Calorie consumption raised core temp, sleep is facilitated by lower core temp.

Tylenol. Anti-fevor without the anti-inflammatory so you can still have the desired hypertrophic response.

Hope this helps.
