It is believed that there are cold as well as hot hells. The least of the cold hells is called Arbuda naraka. Blizzards blow across this frozen cold plain through which lonely naked people walk for a few trillion years. There is also a belief that the bodhisattva Ksitigarbha tries to bring help to those who live here. It is said that his method is to convince people who live on earth to transfer a bit of the merit of their good deeds to those who live in hells. I suppose the idea is that kindness and caring works.
The good news is that social changes are working. Six months into the pandemic, 20 million out of 8 billion people have been infected; that is one fourth of a percent. I guess wearing masks counts as part of this transfer of merit.
