At this moment my room air temperature is 73F and relative humidity is 30% which makes wet bulb temp as 13C. This is a very virus fav climate. That means, if I carry virus in my nasal airway, my body will most likely keep replicating at this temp.

This is a typical indoor during winter in USA. Depending on outdoor climate, indoor RH also varies. I generally do nothing except body gives me some signal. Furthermore, I recently recovered. But still, I occasionally sleep keeping humidifier on so that room RH goes above 50%.

Before getting COVID, I usually kept wearing mask too often especially indoor in winter. In 2020, my home was very small (650 sq ft). Therefore, my room WBT remained around or above 15C most of the time (3 people constantly lived indoor). (cont)

Normal household work (such as cooking, bathing etc) and exhalation usually kept humidity high. During winter ventilation is also low. Therefore, living in a small home is remarkably beneficiary.

I used to measure humidity & temp in my lab (socially distancing) & in my home (crowded) frequently. My lab WBT was at virus fav while my home was not. I always kept wearing mask in the lab. I believe mask do not block virus particle sufficiently but it keeps nasal airway warm

But I used to believe that mask alone was not enough in very dry indoor. However, as my home WBT was at the safe range, I didn't bother too much. I moved to a new apartment (1000 sq ft) in a different city at the beginning of 2021 where it was difficult to control indoor climate.

Within 10 days after moving to that apartment, I became sick first time during pandemic. It was mild COVID like sickness, but I didn't test positive. Then I used to do a lot of things to keep myself & my family safe such as taking hot shower everyday, living all 4 people (cont)

in the same room while running humidifier on. When summer arrived, we never used AC. It was in Delaware. Keeping window open was enough and we kept living tension free. Now we are in the winter again and my current apartment is small which made my life easier.

Perhaps it is also helpful that I recovered at earliest stage of the winter season. Still more than two-three (some area may have separate winter & spring surge and some areas may have combined surge) months people may have to live very cautious. (cont)

I assume many people will get COVID because of this current case rise. I am a vaccine critic. The positive role of vaccine is very narrow while negative role (such as no protection in virus fav weather or it could also be possible that vaccine helps in virus spreading) is high.

People at this moment depend heavily on the mask because vax'd people are getting COVID. If you are in a physical working mode, you may consider mask as helpful. If you are in a resting mode, mask may not be helpful. I would recommend to add a face shield.

I also believe that indoor physical exercise is helpful. Taking shower with sufficiently hot could be helpful. However, after taking shower, I would recommend to keep wearing mask another 30 mins or so. It could be helpful stay in humid and warm condition 10-15 after shower.
