Color is everywhere, yet it’s surprisingly difficult to pin down. Are we all seeing the same colors—or just calling them by the same names? Why are some colors calming while others feel energizing or even unsettling? Kory Stamper, lexicographer and author of True Color: The Strange and Spectacular History of Defining Color—from Azure to Zinc Pink (https://amzn.to/4boSslv), explores how humans perceive, describe, and emotionally respond to color.
Heat is usually something we try to avoid. Too much of it can be dangerous. But emerging research suggests that controlled exposure to heat—through saunas, hot baths, or other methods—may offer surprising benefits. Bill Gifford, author of Hotwired: How the Hidden Power of Heat Makes Us Stronger (https://amzn.to/4lGvRnZ), explains how heat can improve cardiovascular health, boost performance, and trigger powerful adaptations in the body that many people overlook.
If you need to stay sharp and focused, one simple habit might help more than you’d expect.
