Want better sleep? Try picking up a book before bed. A 2021 study known as the Reading Trial found that 42% of participants who read before sleep reported noticeable improvements in their rest. But there’s a catch: how you read matters. Avoid screens or harsh lighting that can suppress melatonin. Instead, create a calming atmosphere: dim your lights, use a small reading lamp with a warm hue, or wear blue light–blocking glasses.
