How frequently should Windows 10 be rebooted

Hi,

I try to avoid rebooting, by closing the lid of my notebook into sleep
mode. However after a long time (a few days) things stop working, like
Task Manager fails to display WiFi stats. So I close and open it and it
works properly again. Maybe there is something wrong with my hardware. I
have never done memtest, I don't know how. Maybe a cosmic ray might
change a bit, but I live at sea level. On occasion my machine will
freeze up or reboot spontaneously.

To be on the safe side, how frequently should Windows 10 be rebooted?

Thanks in advance.
