Sleep helps your brain process information quicker. In fact, after just one night of sleep deprivation, cognitive processing speed drops significantly — meaning it takes longer to respond, solve problems, or even hold a conversation.

🧠 A study from the Journal of Sleep Research found that even partial sleep loss led to "significantly slowed reaction times and reduced alertness" the next day.

Every night, your brain decides what to keep — and what to toss. During deep sleep (slow-wave sleep), your brain consolidates important information and discards the rest, helping you focus on what really matters the next day.

🧬 Harvard researchers found that this process is essential for memory formation and clear-headed decision-making.

Sleep supports the prefrontal cortex, the area of the brain responsible for logic, reasoning, and impulse control. Skimping on sleep weakens this region — making you more impulsive and less rational.

⚖️ One study published in Nature Neuroscience showed that sleep-deprived individuals were more likely to make risky or irrational decisions in financial tasks.

Ever wonder why your best ideas come in the morning? REM sleep boosts creative problem-solving, helping your brain connect unrelated concepts — a critical skill for work, strategy, or any kind of innovation.

🎨 UC San Diego researchers found that REM sleep increased people's ability to solve problems by up to 30%.
