Hostas are hardy. Like most plants they will not like the roots being frozen, so if they are in a pot, put it somewhere sheltered. If in the ground they will be OK.
jackojkh, hostas are hardy perennials and tough as old boots. in winter if planted in the ground the foliage completely disappears and the plants looks as though they have died. Don't worry, in spring they will reappear as if by magic. Place plenty of grit around the plants because the slugs and snails will be waiting for them to appear! Mine do better planted into permanent pots which are left outside all year round and don't get eaten by the slugs as much. Beautiful plants, one of my favourites.
Life's tragedy is that we get old too soon and wise too late.
I think they are probably at greater risk from slugs but you would be better with the pots and plants in the ground so the root ball does not freeze up. It depends on your local climate.

In the sticks near Peterborough

I think only slugs can kill a Hosta
Deer are , allegedly, very fond of them too.

Our deer don't eat the leaves, but do take the flower spikes off
Thank you

Is it ok to leave them in sunny area during winter?
Great question, i had been thinking the same, have two small pots of hosta
