Before the quarantine began, I used to gorge on food and soda at work (the food courts are priced pretty low, considering the quality). Working from home served as a change in environment that I leveraged to start building a healthier eating habit (keto + intermittent fasting) that has in the last three weeks, helped me lose an encouraging number of pounds.
I've been monitoring my food, and even more so, now with covid.
Before covid, I used to be a workaholic, and sleep 5-6 hours/day, sometimes even less. Now, I'm more like sleeping 8-9/day, to boost my immune system.
On the "why" part: I want to be as healthy as possible if the virus hits. I'm on the 40+ age group, so yeah - I do worry a little.
I highly recommend: a) sleep 8+ h/day; b) conscious eating (less); c) sports (indoors if possible)
I'll say though, before the quarantine, I used to go out to do grocery shopping or to cafes a lot more, so now I'm getting less sunlight and cardio than usual. Soon I'll even forget how to talk to people.
