In less than a month I'm going to Vietnam for a period of three months. It's the hottest period of the year, which is why it's not uncommon for locals to adopt a biphasic sleep schedule - to sleep a few hours during the freshest moments of the night and to have a nap after lunch.
I want to get back to a biphasic sleep pattern myself. I will be forced to anyway once I arrive in Vietnam, for productivity purposes.
I need a lot of sleep at night, which I confirmed throughout years of experimenting with my sleep schedule. Just going to sleep without putting an alarm on and noting down how many hours you slept tells you about the amount of time your body needs in order to heal. I need either seven or nine hours to feel rested myself, which makes sense since the duration of a sleep cycle is about 90 minutes.
It's not uncommon for me to wake up in the middle of the night or to feel like having a nap after lunch. I have the strong intuition my body is naturally inclined toward a biphasic sleep pattern, but it's hard to develop a new sleep pattern when you have a schedule to refer yourself to. I mean, who does a nap at his office, right? It's badly perceived by society.
Fortunately, I'm no longer bound to a specific schedule, therefore I am free to do whatever it takes to settle in this new habit.
Tomorrow I will write about how I'm planning to adapt, wish me luck.
