All exercise is basically a chill pill, but high-intensity interval training (HIIT), which focuses on short, intense bouts of activity interspersed with periods of recovery, is especially potent. "Animal research shows HIIT lowers inflammation in the hippocampus, the part of the brain where our emotions come from," says Petrucci. HIIT has also been found to decrease inflammation in type 2 diabetes patients, as well as in people who are obese or overweight. Petrucci says doing HIIT three times a week for 10 minutes will give you the best benefits.
