Why Am I Exhausted but Can't Sleep?

Exhausted and sleepy are not the same thing

Exhaustion is how depleted you feel. Sleepiness is your body actually being ready to fall asleep: heavy eyes, reading the same line three times, nodding off. You can be completely exhausted and not sleepy at all.

Stress, long days and broken nights wear you down, but they also keep your alert system switched on. So you feel flattened by tiredness and still lie there wide awake. If your evenings feel like the day is still running in your head, I go deeper into that pattern here.

Why trying harder makes it worse

Sleep is one of the few things in life that effort doesn't improve. The harder you try, the more awake you get. Checking the clock, doing the math on how many hours are left, lying perfectly still and willing yourself under all send your brain the same message: this matters, stay alert.

Do that for a few weeks and your brain starts linking the bed itself with being awake and frustrated. Ever notice you're nodding off on the sofa, then wide awake the second you get into bed? After a while, your brain starts expecting you to be awake there. CBT-I helps you retrain that association so bed becomes a place for sleep again.

The habits that keep the cycle going

We all do these, with the best of intentions:

• Going to bed earlier to catch up. It just adds more time lying awake.
• Sleeping in or napping after a bad night. It drains the sleep drive you need for tonight.
• Staying in bed for ages when you can't sleep.
• Watching the clock through the night.
• Cancelling plans or skipping exercise because you're tired. Your days get flatter, and your nights don't get any easier.

What helps when you're exhausted but can't sleep

• Go to bed when you're sleepy, not just tired, even if that's later than you'd like. Yes, it feels backwards. It works.
• If you've been awake for what feels like about half an hour and you're getting frustrated, get up. Go somewhere with low light and do something quiet and dull. No screens, no work. Go back when sleepiness comes back.
• Keep the same wake time every morning, weekends included, however the night went.
• Turn the clock away from you and skip the math.
• Give your day somewhere to land before bed. A few minutes of writing down what's on your mind keeps it from showing up in the dark.
• Stop trying to sleep. Rest instead. Let your body be heavy, breathe slowly, and let sleep arrive on its own.

These are some of the building blocks of CBT-I. In my program we put them into a six-week plan that fits your schedule and your sleep, because timing and order matter. Some pieces, like adjusting your time in bed, really are better with guidance than on your own.

When it's worth talking to your doctor

Mention it to your doctor if you notice:

• Tiredness that has lasted for weeks and doesn't improve with rest
• Loud snoring, gasping or pauses in your breathing
• An urge to move your legs in the evening
• Low mood, or losing interest in things you usually enjoy
• Hot flashes, night sweats or other midlife changes (CBT-I can help with sleep through midlife changes. See my article on CBT-I, menopause and hormone therapy.)

Iron, thyroid, hormone and mood changes can all play a part, and they're treatable. Please don't start, stop or change any medication or supplement without talking to your doctor first.

Exhausted but can't sleep doesn't look the same for every woman. For some it's a racing mind, for others it's a body clock that's drifted, and for others it's the bed itself. The Find Your Sleep Profile quiz takes about two minutes and shows you which pattern fits you and what it means.
