Breaks you take from studying, how long they are, and what you do

After reviewing all the studies and research that's out there, here's my best advice: Take SHORT breaks – say 5 to 15 minutes – every hour or so. Take a longer break – at least 30 minutes – every 2 to 4 hours (depending on your task)

From 5-15 minutes, I make food, answer messages, and stretch.

umm i have no idea what that is good luck : )
