Sweat: It Makes You Smarter

Who Wudder Thunk ~~ Working up a sweat makes you smarter, less forgetful and happier!

According to a study in Psychology Today, when brain-imaging studies in humans and neurochemicals studies in animals were performed, scientists found evidence that exercise makes a stronger brain.  Physical exertion induces the cells in the brain to reinforce old connections between neurons and to forge new connections. This denser neuron network is better able to process and store information, essentially resulting in a smarter brain.

It turns out that the brain-body connection is stronger than anyone thought. Shaking a leg (or curling a Man rowingbicep) doesn’t just make you stronger, healthier and better-looking—it also helps your brain shrug off damage and the effects of aging.  We all lose brain tissues, but it seems that by working out, we lose it much slowly.  That’s good news for an aging brain.  Remember, when you are sweating it out at the gym, you’re making a very smart move.  

Writer, MADELINE HALLER, from MensHealth, gives us three more ways sweat makes you smarter.

1. You Remember More

Incorporating a short burst of exercise into your daily routine may strengthen your memory, says research published in the Journal of Alzheimer’s Disease.  People who cycled on a stationary bike for 6 minutes were able to remember more images an hour after riding than those who stayed sedentary. Researchers credit the exercise-induced release of norepinephrine—a chemical in the brain that plays a role in memory—for the brain boost.

2. You have more Willpower

A study in the British Journal of Sports Medicine found that shorter, more intense bouts of exercise enhanced people’s self-control, problem-solving, and verbal reasoning.  Scientists suspect that acute exercise increases blood flow to your prefrontal cortex, the area of your brain that controls executive functions.

3. You Make Smarter Decisions

Researchers from the University of Illinois reviewed over 100 studies and found several connections linking exercise to better decision-making and multitasking skills.  Studies also found that exercise stimulates your body’s production of a protein called insulin-like growth factor-1, which has been shown to fire up the growth of neurons and enhance cognitive performance.  The best part: Most of the research indicates that sweating 3 days a week for 30 minutes is enough to see an effect.

If you’re still puzzled about how sweat makes you smarter just from exercising, see the details from a CNN article on the Science Blogs.

The New Year will soon be approaching, so let’s try to make it a great year by choosing to do more cardio for a smarter you!
