I'm a 22 year old male that will be entering medical school next fall. I'm highly active, and exercise at least 5 days per week, typically 1-3 hours per session, whatever time allows. I'm thinking of starting a biphasic sleep routine for a number of reasons, mainly, a lack of productivity at key points of the day (midday and late night).
I've often faced the problem of a lack of productivity around 3 PM, and I'm wondering if biphasic sleep helps with this. I've been told that it's a blood glucose level problem, as most people's levels drop down below 70 mg/dL around this time, but I can drink a caffeinated milkshake around 2:30 and still feel tired at 3 PM.
Anyway, like I said, I'm wondering if any biphasic sleepers have found the cure to the midday crash.
Also, which cycle is it best to start the routine with? The nap or core sleep?
