Why do we feel more awake at night sometimes?
You're lying in bed. It's late. You should be sleepy. But instead, your brain is wide awake, buzzing with thoughts, and your body feels like it could run a marathon. What's going on?
Inside your brain, there's a tiny cluster of cells called the suprachiasmatic nucleus — your body's master clock. It runs on a roughly 24-hour cycle, telling you when to feel alert and when to feel sleepy. But this clock doesn't run on its own. It needs signals from the outside world to stay on track.
