The human body is more susceptible to illness when it’s exhausted. The immune system releases a protein called cytokines during sleep. That protein is essential in the body’s reaction to a incoming virus. So, in short, if you’re not getting enough sleep, you’re more susceptible to feeling the impact of the an incoming virus.
I’m not trying to diagnose why the Lions suddenly have a huge COVID outbreak. That is clearly just a reflection of the entire league, which has placed 75 players on reserve/COVID-19 over the past two days.
But, instead, it seems like the Lions put everything they possibly could into that Week 13 walk-off win, and now they’ve got nothing left.
