The recommended daily limit to caffeine intake is 300 mg. A cup of regular coffee can contain anywhere from 80 to 130 mg whereas tea, even strong black tea, only contains 40 mg. Still, it was enough to keep me tired and restless well past midnight. Apparently, I'm not only sodium-sensitive but caffeine-sensitive as well. According to my Sleep Cycle app, I spent 6 hours and 20 minutes in bed, but only slept for 5 hours and 42 minutes. Ugh. Well, at least I slept. What I don't understand is how the app determines that I slept the same amount the night before but achieved lesser quality sleep (67% vs 76%). My husband will swear that the app is just randomly assigning values. He might be right.
Eventually, I'll get used to early mornings. I like that the gym isn't very crowded. This is going to be horrible once winter and daylight savings coincide so that we're all waking in the middle of the night. Friday is my cardio routine day. I don't even pretend to lift any weights, but I do a lot more pull-ups. I've also finally replaced pushups with a single 60-second plank at the end of the Core routine. I might move it to the beginning though when I'm less likely to quiver through it due to fatigue.
I do a set of T, Y & I Raises with 5 lb DBs. I used to do two sets of this in my warmup before whacking the Nexersys kickboxing machine. The exercise itself isn't hard, but as I'm lying face down on the bench, I worry about whether my head is above my heart. Glaucoma patients are told not to let their heads drop below their hearts because that increases IOP (intraocular pressure). Some patients don't even put their socks on anymore unless they can use a grab-it stick so as to keep their heads elevated. Keeping my head up puts a lot of strain on my neck and I'm still worried about my IOPs. Ugh. Not doing those anymore.
In total, I do 75 minutes of heart-pounding cardio, three sets of pull-ups, some ab work, stretching and a few rounds of seated leg curls. I'm tired when I start, even stifling a yawn during crunches, but oddly and happily energetic when I finish. Maybe even annoyingly so. It's a combination of the body's endorphins kicking in, a revved-up metabolism, and increased blood flow, i.e., there's more oxygen getting to the brain. In the 2014 Fast Company article "What Happens to Our Brains When We Exercise And How It Makes Us Happier," Leo Widrich succinctly explains the function and importance of the BDNF (Brain-Derived Neurotrophic Factor) protein and the impact of endorphins in our bodies.
