Take a break every 90 to 120 minutes to reboot your mind and body. It's not only good for your health but also your productivity.
Did you know your brain can only focus for 90 to 120 minutes before it needs a break? No joke. By design, our bodies have a natural cycle they move through within a 24-hour to maintain our mind/body health. These are called our ultradian rhythms.
The ultradian rhythm itself was first discovered in sleep research by Nathan Kleitman. He called it the “basic rest-activity cycle” which is a 90-minute cycle during which you progress through the five stages of sleep. Kleitman found the 90-minute pattern not only exists during sleep but also during the day as we move from higher to lower alertness. You probably notice that time of day about 2pm to 4pm when we feel the need for a stimulant to keep us going. When we live out of balance with our ultradian rhythm, we have this dip in the afternoon.
