Below are some tips on some recommended breaks:
Go for a walk and/or exercise.
Walk the dog, go for a run around your neighborhood, play hopscotch with the kids, etc. Being outside and moving builds endorphins which can lead to positive feelings (reduce stress, ward off anxiety, boost self-esteem, and improve sleep).
Work on your hobbies.
Build a Lego village, work on that puzzle, play an instrument, pick up that woodworking project, etc. The work you do in your role may use a different part of your brain than your hobby does. Give the work part of your brain a rest while enjoying that hobby.
Take a noontime nap.
Naps have some great healing benefits (increases alertness and improves focus). Catnaps are good for business!
Meditate to unwind.
There are a lot of helpful apps that walk people through meditation if you are a newbie. This activity helps disconnect you from work and focuses on you through breathing techniques and clearing your mind. Meditation takes practice but worth it.
Have a snack or drink coffee/tea.
Healthy snacks keep the brain pumping out good ideas and great work. Vegetables, fruit, and nuts are good snacks to have on hand during a break. Kicking back for a few minutes with a coffee or tea also helps people unwind and recharge the creative juices.
Doodle like a boss.
Doodling is a super simple break from work. Draw a self-portrait, create your ideal vacation spot, illustrate a legendary space battle, etc. It may be horrible but WHO CARES?! The point is to step back from work.
