"Flexibility is crucial for physical movements and can help prevent injuries, decrease inflammation, modulate physical and mental pain, impact exercise recovery speed and even potentially slow the progression of certain diseases"
Andrew Huberman
“Physical activity has many direct effects on the brain. One is to flood the brain with mood-altering chemicals. As a reminder, exercise heightens the activity of transmitting molecules in the brain, notably dopamine, serotonin, and norepinephrine. These neurotransmitters induce sensations of reward, well-being, arousal, and memory enhancement. Most pharmaceuticals such as SSRIs used to treat depression and anxiety manipulate levels of these neurotransmitters.”
