Cognitive performance isn't static throughout the day; it changes according to our circadian rhythm. For most, the brain hits its stride in complex tasks like problem-solving or learning new things late morning to early afternoon.
This isn't random; it's when melatonin dips, body temperature rises, and key neurotransmitters like dopamine and norepinephrine spike, enhancing focus and attention.
But here's a twist: when it comes to creativity and divergent thinking, late afternoon or evening might be your sweet spot. Why? Because during these off-peak hours, our brain's inhibitory control dials down, allowing more fluid, creative thought processes.
Vigorous exercise forces the muscles to produce lactate, which then travels to the brain, triggering the production of key neurotransmitters like serotonin and norepinephrine.
Low levels of norepinephrine and serotonin are linked to anxiety as they hinder our capacity to manage stress, often resulting in a state of learned helplessness.
Analysis of 15 studies found that exercise, particularly vigorous exercise, is effective in alleviating symptoms of anxiety.
