Yes. And if you have to be inside, open the widows and gets lots of air changes through your house. Don’t let the virus get concentrated anywhere.
During the Spanish flu, all those many years ago when they had virtually no treatments for anything, there were so many people ill that they had to build overflow outdoor field hospitals. The people placed in those - basically large tents either without sides or with flaps they could let down if necessary - recovered at a rate several times greater than that of the people who were in the actual (airless indoor) hospitals.
When it’s 30 to 40 outside, it’s a bit chilly to open the windows for more than a few minutes. In my location, we’ve had only 3 days in the last month that got above 70. So it’s hard to keep the windows open for long.
