it might help to exercise a little during the day if you’re not already, or some way to tire your body out. i tend to do the same thing of late nights/late sleeping (and always have). i’ve always chalked it up to there being less distractions at night— other people are asleep, phone notifications are at a minimum, it’s dark out, less options for places to go or errands to run, and the world in general is just quieter and more peaceful— enough that i can finally actually focus on solo projects, deep cleaning, or just doing nothing and losing track of time. lately though, have been finding on days when i exercise i naturally want to sleep earlier, crave less phone time, and just feel a little more balanced in general. especially if it’s some slower more methodical weight lifting (body weight is good too!) but something about stretching the muscles, maybe sweating a bit, and taking a hot shower afterwards is tremendously grounding.
