Why am I tired but can't sleep at night?

Being tired and being ready for sleep are not the same thing. When you are overtired, your body's fight-or-flight response can stay switched on, so your brain stays alert while your body is worn out. Racing thoughts and worry about not sleeping then keep you awake, and the more you think about sleep, the harder it gets.

Sleep medicine specialists describe it as a brain and body at odds with each other. Frequent waking and the urge to scroll your phone or watch TV instead of resting are common signs.

What may help: keep the bedroom cool, dark and quiet, hide your phone and clock, and avoid caffeine, alcohol and late-day exercise. A wind-down routine of about 15 to 20 minutes can signal the end of the day. If you are lying awake, try reading a boring paper book or a mental exercise like counting down from 100, and avoid stimulating screens.

If this happens regularly, see a healthcare provider. They can check for causes such as anxiety, thyroid problems or anemia, and may suggest cognitive behavioral therapy for insomnia.
