There’s something almost hypnotic about staring into a fire. Whether it’s a crackling campfire or a looping fireplace video, the effect is the same, your shoulders drop, your thoughts slow, and time seems to stretch out. Scientists say that reaction isn’t just about cosy vibes, it’s deeply wired into us. One major explanation comes down to evolution. For hundreds of thousands of years, fire meant survival. It provided warmth, kept predators away, and created a safe space for early humans to gather.
