How AI Is Rewiring Your Brain Without You Realizing

By Dr. Caroline Leaf on June 04, 2025 I’m excited to share something that’s been weighing on my mind lately, and I think it’s something we all need to talk about.

The Difference Between Rest and Restoration

I want to talk about the difference between resting to restore versus just resting, why rest alone is often not enough, and how to use a Neurocycle to effectively and sustainably restore your mind and brain. How many of you have ever binge-watched a Netflix show because you desperately needed a break, only to feel completely unrested the minute the binge ends?

4 Keys to Raise Empathetic Children

How Forgiveness Changes Your Brain

“Bear with each other and forgive one another if any of you has a grievance against someone. Forgive as the Lord forgave you.” Colossians 3:13 NIV Forgiveness is more than just a word or action.

How to Help Your Child with Depression and Trauma

It is estimated that around one in twelve children struggle with depression at some point between the ages 9 and 16, with girls more likely to be affected than boys.
