how to get 30 minute break while working or doing anything on computers?

Question

I am running Debian. Many a times I get cramped or something for being on the computer for hour or hours than is good for me. Is there a tool which will tell me after 30-40 minutes to take a break ? I remember seeing something but have forgotten about it.

Answer 1

I use Workrave for this; it’s available in Debian as the workrave package.

I also noticed Safe Eyes, available as the safeeyes package, but haven’t tried it.

Answer 2

xwrits available in the standard repository is another one.

Description: reminds you to take a break from typing
 xwrits helps you prevent repetitive stress injury.
 .
 xwrits is a small reminder program designed to let you know it is time
 to take a break from typing to rest your wrists and prevent any damage
 to your wrists (or at least make them feel better if you've already
 damaged them). Normally works on the honor system, but if you find
 yourself unable to stop typing during your break, it can also lock your
 keyboard.

Answer 3

You can use Stretchly as a break time reminder:

A microbreak for 20 seconds every 10 minutes.

Every 30 minutes, it displays a window containing an idea for a longer 5 minute break.

The description is available on github. To install stretchly download the .deb package from here

wget https://github.com/hovancik/stretchly/releases/download/v0.18.0/stretchly_0.18.0_amd64.deb
gdebi stretchly_0.18.0_amd64.deb
