Does anyone wash dishes in cold water?

Is this ok?

No it's not.

The heat helps clean them. It should be hot too. Hot so as to need gloves really.

My DH's family live overseas. They only wash their dishes in cold water. No one has died.

It depends. Solid grease will melt easier, but what happens in washing is that dirt goes into the water and is held there by detergent. I don't know how much this process is improved by heat..

If you can at least rinse with hot water that would be better. One of the reasons dishwashers are more effective at killing bacteria is that they heat the water to a higher temperature than you'd ever use for washing by hand.

This sounds reasoned..

No, you need hot water to clean.
