ENERGIZER: A mini meditation

The brain starts producing less GABA—the neurotransmitter that gives you calm, steady energy—at age 40. But studies at Boston University suggest that meditating for even just 5 minutes activates the brain enzyme that produces GABA, boosting levels by 27 percent. To get the perks, sit with your neck supported and relaxed, close your eyes and take deep breaths, focusing on the air flowing in and out of your body.
