This weekend I picked up a bug. When I say a bug, I mean really icky sickness. I am the person that will get a runny nose when everyone else is laid up in bed, an upset stomach when others are bowing to their porcelain god.
Sunday night I missed my evening nap, so I went to bed at 12:30 so I could get 4.5 hours of sleep. I had been feeling sort of funny that afternoon, but I believed it to be just allergies, very runny nose, lots of sneezing, some congestion, things like that. I got my 4.5 hours and got up at 5, barely dragging myself out of bed. I thought it was just difficult due to sleep inertia, (the reason I prefer 3 hr to 4.5) so I went about my day as normal. At work I wasn't feeling much better, I started to feel chilled which is very unnatural for me, it takes a lot more to make me feel cold than most of my friends. In addition to that, I noticed that I was getting sore muscles/cramps in my legs. I went to take my morning nap around 11 and got little or no rest due to congestion, soreness, and being cold. It was about the same for my 4:00 nap, although I believe I got a bit more rest, but not a full nap.
That evening I felt like a zombie so I went home, laid down to rest at 7:30 and was asleep by 8. I woke up at around 3:45, very groggily drug myself into the bathroom to clean out my nose, (ugh, brown) get water, etc, and went back to bed. At some point my body had enough sleep, so I kept waking up and just sitting there, drifting in and out of sleep letting my body get the rest it needed to fight the sickness. I finally got up and about around 10:00 for a bath/shower, then laid on my bed for another hour or so, not sleeping, but resting more. I finally got up feeling a lot better and headed to work for a half day with an abundance of rest, but still somewhat groggy from all the melatonin in my bloodstream. (sleep inertia, yay)
I tried to take a nap that evening, (last night) but I wasn't able to really fall asleep, it was nice to lay down for a while, if only to keep on schedule. Today I feel much better, naps should not be any trouble, and the drippy nose is down to a minimum. Everything seems to be on its way out, I'm happy to have beat the crud.
All in all polyphasic sleep has always seemed healthy, there have been people who attack polyphasic sleep as unhealthy because you are not getting enough sleep/sleep deprivation is unhealthy. To a point they are right. Polyphasic sleep is not sleep deprivation, however you do not get as much rest as you would on a monophasic schedule. Normally your body will not need as much rest as you give it unless you work your body extra hard. However, if you begin working out, do some hard labor, experience a lot of stress or get sick, your body may need more downtime, physically, in which case a polyphasic schedule may not be sufficient. Does that mean it's not good enough? Hardly. I have experienced similar sicknesses in my past and know enough that I probably would have spent a similar 12-16 hours attempting to recover even if I was getting 8 hours of sleep a night.
I suppose this serves as a reminder that while you might feel amazing being up at all times of the night/morning, you are not superman, there are weaknesses in your armor. Polyphasic sleep is not perfect, however neither is monophasic sleep, so pick your battles and know the weaknesses, if dropping off my schedule is the price to pay for getting really sick for the first time in...nearly a year I believe, it's worth it to me.
