New research shows caffeine disrupts sleep only in early-rising 'larks', not in late-sleeping 'night owls'. Find out who should avoid afternoon coffee.

If you’ve ever blamed your coffee habit for a sleepless night, you’re not alone—but the truth is more nuanced. For some coffee drinkers, a midday espresso leads to tossing and turning well into the night. For others, even multiple cups after lunch barely affect their ability to fall asleep. Why the difference? New research sheds light on how your body’s internal clock determines whether caffeine keeps you up.
