This is a particularly cool one. Neuroscientists used to believe the brain was the only organ incapable of growing new cells—which partly makes sense, since we need our brains to be relatively stable over time, to keep our memories intact and to keep us us. But in recent years, it’s become clear that the brain, too, can grow new neurons, in a process called neurogenesis. And what seems to spur the growth of new neurons, perhaps above other activities, is aerobic exercise. (Other things, like meditation and antidepressant medication, have also been shown to trigger brain new cell growth.) The area of the brain that seems most capable of growing new cells is the hippocampus, the seat of learning and memory. It's also the area that’s known to “shrink” in depression, and particularly in dementia—so the fact that we may have some control over its health is exciting.
Get 7-9 hours of sleep each night. Sleep is a crucial component of fat loss and muscle building, which happens most effectively when your energy consumption is lowered. Aim to get between 7-9 hours of sleep each night by establishing a sleep routine to follow, including a 60-90 minute period to wind down before bed. During this time, shut off your phone and do something relaxing, like reading or meditation.
