If you work a lot on a PC you should also take many breaks. If you are like me and forget about this very often you could use this trick to force yourself to take the break.
- [x] Lock screen to enforce typing break
- Work interval lasts eg. 45 minutes
- Break interval last e.g 3 minutes
- [ ] Allow postponing of breaks. (disabled for me because otherwise I would postpone it everytime ;-) )
Now you have to take a break every 45 minutes for at least 3 minutes. You should stay up go to the toilet or simply move and stretch your body.
Another possibility is to archive this is to use the external tool workrave.
