Some people take breaks. Kwik recommends a “brain break,” which includes three things:
Move: Move your body, “because as your body moves your brain grooves, which gives you energy, great brain-derived neurotrophic factors, which is like fertilizer for your brain,” he says.
Hydrate: “Just staying hydrated boosts your reaction time and thinking speed upwards of 15 to 30%. Your brain is mostly water,” he says.
Breathe: Yes, do some deep breathing. But also sit up straighter. “A lot of times people can’t maintain their energy to get the things they need to done, because their posture is so bad, and the lower third of your lungs absorbs two-thirds of the oxygen,” he says.
