For the last three days I’ve been experiencing a significant dip in energy and function in the later afternoon around 4pm.
Not only am I fatigued, but I seem to have some sort of either allergic response or potentially common cold symptoms. It’s a little unclear as I don’t have consistent symptoms nor do I have a fever.
Some of it is probably jet lag as I returned home to Montana after a month in Europe over the weekend. I haven’t quite recovered my sleep deficit as I am pushing very hard on my workload as well.
I tried doing a bit of polyphasic sleeping today to see if it might help abate the intensity of the dip. The idea behind polyphasic sleep is to get your required 7-8 hours not in one monophasic chunk at night but across your own natural energetic ebbs and flows.
I did a packed morning of work and meetings and then slept between the hours of 3-5pm. I do feel better having been asleep during the dip but I could feel the symptoms rising while in the light sleep mode. I wasn’t able to fall into deep or REM sleep.
Whatever is happening I clearly need more rest. My attempts at diagnosis of any other symptoms and their proximal causes are unlikely to matter if I’m not getting adequate rest. In which case, I’ll try to sleep more at night and add in some naps till it passes.
