Summary

That eerie feeling that someone is watching you—even when no one is there—can be surprisingly convincing. It feels almost like a sixth sense. But where does that sensation come from, and can you actually trust it? https://pubmed.ncbi.nlm.nih.gov/10707330/ 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. It’s easy, inexpensive, and something you’ve probably done before without thinking much about it—but under the right conditions, it can give your brain a noticeable edge. https://pubmed.ncbi.nlm.nih.gov/26075234/ PLEASE SUPPORT OUR SPONSORS DUTCH: If your pet is still scratching and you’ve tried everything at the pet store –it’s time to stop guessing and go prescription.Support us and use code SYSK for $40 off your membership at ⁠⁠https://Dutch.com⁠⁠ RULA: Thousands of people are already using Rula to get affordable, high-quality therapy that’s actually covered by insurance.
