Your brain's dopamine system wasn't designed for infinite scroll, autoplay, and variable notifications. It was designed for earned rewards — and social media is engineered to exploit the gap between those two realities.

In this episode, Dr. Kelsy Vick closes out the April Spring Cleaning Series by breaking down what dopamine actually does in the brain, how social media platforms are specifically built to trigger tolerance and receptor downregulation, and why real life starts to feel flat when your reward system has been worn down.

Plus — the personal story of traveling with her phone on airplane mode and what it revealed about how automatic scrolling had actually become.

What you'll learn:

• Why dopamine is your brain's engine for motivation, not just pleasure
• How infinite scroll, pull-to-refresh and variable notifications exploit your reward system
• What "dopamine scrolling" actually is — and why researchers named it a public health concern in 2025
• The science behind why real life feels flat after chronic overstimulation
• 5 evidence-based ways to restore your dopamine system starting this week

This is the spring cleaning your brain actually needs.
