Is it ok to have fan blowing at me during confinement since there is no aircon at home? Must we really also wear long sleeves and pants at home under this hot weather? Appreciate your advice. Thanks.

It is up to individual to believe, after all they are just myths! I did not wear long sleeves or long pants as it was way too hot during my confinement period. If you have elders around, maybe you can let the fan blow around instead of blowing straight at you.
