TAB - Take A Break 作者： WonderNote18

A web extension that aims to remind and notify users to take breaks during their time browsing the web or completing other activities by:

• Readjusting your vision after focusing on a screen (15 - 30 mins)
• Correcting your posture while sitting down (20 - 45 mins)
• Get up and stretching your body after sitting for a while (30 - 60 mins)
• Re-hydrating by drinking some water (45 - 90 mins)

Each of these options are able to be toggled from the extension pop-up (when clicking on the icon in your browser), and can be configured for custom timers between notifications (based on studies for recommended time ranges for each type of break).
