There's one thing I didn't see mentioned: have your significant other remind you of some chores you promised to do. Sounds like a boomer joke, but there's an explanation why this works: our hunter-gatherer brains aren't equipped to deal with tasks without a clear survival-related reward, so they produce a feeling of tiredness/sleepiness instead to prevent us from wasting energy. I've been using this for years now. You need new types of tasks on a regular basis though, because the effect wears off with usage. One additional thing I can think of is cold, fresh air - or simply more oxygen per unit volume of air.
