How can I protect deep sleep after evening workouts?

I’ve been tracking my sleep stages for months, and I notice my deep sleep consistently drops below an hour on nights after I do intense evening workouts. I’m trying to figure out if this is just my body’s specific response or if shifting my training earlier is the only way to protect that crucial restorative phase.

I keep a log and it feels real, not just in my head. After heavy evening workouts I see the stage that should feel restorative staying short, often under an hour, and that pattern repeats for weeks. It makes me wonder if my body is just signaling that it needs more recovery time or if something about the timing is nudging the brain into lighter sleep. I tried shifting the workout earlier by a couple of hours and adding a strict wind down, no screens, a warm shower, magnesium, the usual stuff, and on some nights it helped a bit but not reliably. It’s frustrating because the data looks clean in some vectors but the outcome isn’t predictable.

I’m not sure if I’m chasing the right problem. I tried upping the cadence of easy days around a training block and I still woke up feeling off after late workouts. Maybe it’s not the training timing at all but something like sleep pressure, meals, or stress that’s piling on. Feels like a moving target.

One thing I did was cut caffeine after noon and kept a strict bed time window. On days I did that I noticed the nights felt a touch more restful, but still not a guaranteed fix. I stopped short of turning the whole week upside down because the numbers weren’t consistent.

Do you think the real issue might be how quickly you can settle after training rather than the training itself?
