We all have an awkward ancestor or two. That guy who wore a wolfskin coat and ran around gathering food and chasing wild animals. And that weird girlfriend of his who walked bare breasted and digged in the ground for food.
They didn’t have chairs or Netflix. They didn’t even chill much. However, their rate of depression and anxiety was close to zero.
A Cure for Depression?
There is a connection. Motion creates emotion. Exercise, or daily life as it was for our ancestors, is the single best method for balancing our brain chemistry. It has a proven effect on both depression and anxiety .

Increase Serotonin Naturally for Free
Serotonin is one of the brain chemicals getting pumped up when you move your body . Special serotonin neurons are activated, leading to you making more serotonin and releasing more .
Exercise as a Tryptophan Supplement
Exercise also increases the amount of tryptophan entering your brain  – a persistent effect after exercise. When tryptophan crosses your blood-brain barrier, your brain immediately starts transforming it into serotonin.
Tryptophan Competes with Branched Chained Amino Acids
Tryptophan competes with other amino acids called branched chained amino acids (BCAA) to cross the blood brain barrier . Exercise takes BCAA’s out of the bloodstream [6,7], letting tryptophan enter your brain.
First of all, just start! Start with five minutes of walking outside each day and slowly work yourself up to over 30 minutes a day. The more exercise the better when it comes to brain chemistry.
Exercise like our ancestors moved. Walk and jog almost every day for at least 30 minutes. Run a couple of times a week, and sprint all out a few times a month.
