Can improving sleep improve mental health?

We’ve all been there: tossing and turning, checking the clock, and stressing about not getting enough sleep. But what if the secret to a good night’s rest isn’t in a pill or a product, but in changing your mindset and daily habits?

In this episode, we’re joined by Dr. Sophie Bostock, a leading sleep scientist and founder of The Sleep Scientist. Sophie has dedicated her career to helping people understand the science of sleep and how to build lasting, healthy habits.

We dive into what really happens when we don’t get enough sleep, from the psychological effects on our willpower and relationships to the physiological impacts on our long-term health. Sophie debunks common myths about blue light, alcohol, and cheese, and explains the critical difference between occasional poor sleep and true insomnia. And introduces us to Cognitive Behavioral Therapy for Insomnia (CBT-I), explaining why it’s a more effective long-term solution than sleeping pills.

Finally, we walk through the simple, science-backed habits you can adopt right now to improve your sleep, starting the moment you wake up.
