Korva rescues the ideas worth keeping from podcasts. Each one becomes a Card.
Before singing Journey’s “Don’t Stop Believing,” saying “I am excited” made people sing more accurately and less off-key.
The anxiety-lowering ingredient was being alive. Don’t pet a table.
Petting real rabbits and turtles reduced anxiety in one study. Petting toy versions did not.
Four awful events marked a possible stress sweet spot, while very high adversity harmed wellbeing.
Zero adversity was not the psychological sweet spot. People with some adversity fared better.
About 80% of vagus-nerve fibers carry information from your body back to your brain.
Cold plunges have unconvincing stress evidence. One reported hormone drop appeared only 12 hours later.
Try inhaling for four counts and exhaling for five to emphasize breathing’s calming effect.
Treat sweaty hands and a racing heart as performance resources, then lean into the energy stress provides.
The same person can face one stressor as a threat and another as a challenge.
When the body sees stress as a challenge, blood vessels dilate, blood flow increases, and anabolic hormones support performance.
A challenge response may mean less cortisol, more testosterone, stronger performance, and faster recovery.
Incessant stress dysregulates cortisol, raising the risk of cardiovascular disease, depression, and anxiety.
