Or resetting!

If the body has already started to play up a bit in the cold then I would think that some lubricant somewhere has started to get a bit thick, either due to age or collecting dust, and needs to be cleaned up and replaced.

If left, it will only get worse unfortunately.

The same is true with sticky shutters. They can often be made to work again with a bit of use but it doesn't usually last very long.
