When Being Tired Is More than Being Tired
Do you ever wake up feeling just as tired as when you went to bed, even after a full night’s sleep?
You’re not lazy. You’re not imagining things. And you’re definitely not alone.
Millions of people feel this way every day. It can make simple tasks—like getting dressed, cooking, or even driving—feel exhausting. If this sounds like you, there may be an underlying reason your body isn’t getting the rest it needs.
Here’s a look at what could be causing your tiredness—and what you can do about it.
1. You Might Have Sleep Apnea
Sleep apnea is a common sleep disorder that affects your breathing while you sleep. Your breathing can stop and start without you even knowing, and it prevents you from reaching deep, restful sleep.
An estimated 22 million Americans have sleep apnea, and many don’t realize it.
Signs to look out for:
- Loud snoring
- Waking up gasping or choking
- Still feeling tired after a full night’s sleep
What to do: Talk to your doctor about getting a sleep test. If you’re diagnosed, a machine called a CPAP can help you breathe better at night—and wake up feeling more refreshed.
2. Low Iron Could Be Draining Your Energy
Iron helps your blood carry oxygen through your body. If your iron levels are low, your body can’t get the oxygen it needs, and that leaves you feeling weak and tired.
This condition is called iron-deficiency anemia.
About 6% of people under 50 in the U.S. have it, according to the NIH.
Other symptoms include:
- Pale skin
- Dizziness or lightheadedness
- Shortness of breath
What to do: Ask your doctor for a simple blood test. If your iron is low, you may need supplements or more iron-rich foods like spinach, beans, or red meat.
3. Your Thyroid Could Be Slowing You Down
Your thyroid is a small gland in your neck that controls your energy and metabolism. If it’s not making enough hormones, your whole body slows down—a condition called hypothyroidism.
Around 5 out of every 100 Americans have it, and many don’t know.
Signs to watch for:
- Gaining weight without trying
- Feeling cold often
- Dry skin and forgetfulness
What to do: A blood test can check your thyroid levels. If they’re off, daily medication can help bring your energy back.
4. You Could Have Chronic Fatigue Syndrome (CFS)
Chronic Fatigue Syndrome is more than just being tired—it’s a deep, long-lasting fatigue that doesn’t go away, no matter how much rest you get.
According to the CDC, up to 2.5 million Americans live with CFS.
Common symptoms:
- Feeling exhausted even after sleeping
- Brain fog (trouble thinking clearly)
- Body aches or sore throat
What to do: There’s no single test for CFS, but your doctor can help rule out other issues. Light exercise, better sleep habits, and stress management can help many people feel better over time.
5. Depression Can Cause Deep Fatigue
Feeling emotionally drained and tired all the time can be a sign of depression, even if you don’t feel sad.
More than 21 million adults in the U.S. have experienced major depression, according to the National Institute of Mental Health.
Other signs:
- Loss of interest in things you once enjoyed
- Sleeping too much—or not enough
- Changes in appetite
What to do: Depression is treatable. Talking to a therapist or doctor can make a huge difference. You don’t have to go through it alone.
How to Start Feeling Better
If you’re tired all the time, here are simple things that can help:
1. Set a Sleep Routine
- Go to bed and wake up at the same time each day (yes, even weekends!)
- Keep your bedroom cool, dark, and quiet
- Avoid screens and caffeine before bed
2. Eat Energy-Boosting Foods
- Try iron-rich foods like lentils, red meat, and leafy greens
- Eat whole grains and plenty of fruit
- Drink enough water—dehydration can cause fatigue
3. Get Gentle Exercise
You don’t need to hit the gym. Try:
- A 10-minute walk outside
- Stretching or light yoga
- Dancing to your favorite music at home
Moving your body—even a little—can help increase your energy.
4. Check in with Your Doctor
If your fatigue won’t go away, schedule a check-up. A few simple tests can rule out serious causes and give you peace of mind.
