| It's tricky, but there are a few options. - Gold standard: this is a perfect use case for sleep tracking. "Wake me in the sooner of 1 hour or 30 minutes of sleep". - Upper bound timing. If I can't start a nap within 15-20 minutes, it's probably one I don't need. So a timer set for 35 min would suffice to get me some reasonable duration. This fails if you might need 30+ minutes. - Caffeine naps. Drink a cup of coffee, start your nap, you'll be up in <40 minutes as the caffeine hits. This doesn't guarantee you'll get a lengthy nap, but it helps ensure you don't wake up groggy. - Practice. I struggle to nap currently because it's not routine, I usually can't sleep quickly unless I'm exhausted. But I spent a good 6 months getting healthy sleep amounts with a daily nap, and I was usually out within 5 minutes when it was expected. |
