I've had exactly one week of little to no sleep every night, and, between my moments of delirium, I am noticing a correlation between the nights when sleep is the worst, and mornings /days when I am the most hungry. Usually I have no interest in food until 11 or so, today I was starving by 8.
Do our bodies compensate for lack of rest with an increased calorie need?
(FWIW, this sleep deprivation is not a choice; I have a screaming-teething infant and a toddler with nightmares)
Clarification: I should have been more specific, bu this is actual hunger, not just a desire to eat. If anything, my enjoyment and desire for food has decreased.
