Sleep patterns and eating habits of Buddhist monks
I heard that Buddhist monks wake up everyday around 3:30 - 3:45 am, and go to sleep around 11 pm - and they sleep upright. Doing the math, it is less than 5 hours of sleep per day. How can they achieve that without feeling prostrated during the day?
I know this has something to do with the eating habits, which I ask you for more accurate information - do they eat only once a day, and fast after the midday? Doesn't the body lack energy because of that?
Maybe the point here is slowing down metabolism, so less food and sleep is needed. Less physical exercising is a crucial point here I think. I feel curious about it, since I want to manage my daily buddhist practices, but I don't feel very well waking up that early - seems like my energy get drained when I do that.
Does anyone have advices on how to schedule your daily practices for fitting in a western living?
