Brain breaks are mental and physical activities to break up a period of concentration.
These may be particularly useful after spending long periods sitting or using technology. The brain break may be relaxing or energizing but they intend to get the body and mind going and re-focus the participants.
Here's a tip!: Brain breaks could be used every hour or less for around five minutes. Try to use a variety, and fit them well to the mood and situation.
For example, you should choose an active brain break if the previous activity is sedentary, or a maths-related one if you have been studying a different topic.
