This is not a good thing. That much sleep will make you lazy and that leads to lot of dangerous things. Social distancing and lockdown are all necessary but try to keep yourself awake find some reason maybe a stupid one at that. As long as you can manage being active and safe. Avoid excessive sleep.
Well I believe it is something you can easily control and change as long as you don't have a sleeping disorder. All you need is to work a bit on your schedule. Anyway good luck.
