Yes, anxiety can make you very tired. Worry keeps your body in a state of alert, which uses energy, disrupts sleep, and leaves you drained even after a full day of doing very little. If you feel exhausted and cannot explain why, anxiety may be part of the reason.
Many people are surprised by this. They think of anxiety as feeling wired or restless, not wiped out. In reality, the two often go together. This post explains why anxiety causes fatigue, what else can contribute, and what you can do about it.
Why Anxiety Makes You Feel Tired
Anxiety triggers your body’s stress response. Your heart rate rises, your muscles tighten, and your body releases stress hormones such as adrenaline and cortisol. These changes prepare you to handle danger. When they happen day after day without a real threat, your body spends energy it does not get back.
Over time, this constant alertness can leave you with persistent fatigue. According to the National Institute of Mental Health, anxiety disorders can come with physical symptoms, including tiredness, trouble sleeping, muscle tension, and difficulty concentrating.
How Anxiety Affects Your Sleep
Poor sleep is one of the biggest links between anxiety and tiredness. You may find it hard to fall asleep because your mind will not slow down. You may wake in the night or very early with worry. Even when you sleep long enough, the sleep may be light and not restful.
It becomes a cycle. Anxiety disrupts sleep, poor sleep makes you more anxious, and exhaustion makes small problems feel bigger. Breaking the cycle often requires addressing both.
Other Ways Anxiety Wears You Down
Besides sleep, anxiety can drain you in other ways:
- Mental effort. Constant worry and overthinking take real energy.
- Muscle tension. Staying tense for hours leaves your body sore and tired.
- Avoidance. Dodging situations that make you anxious can leave you isolated, and isolation can lower mood and energy.
- Changes in eating or activity. Skipping meals or moving less can add to fatigue.
- Using substances to cope. Alcohol and some drugs may feel calming at first but often disrupt sleep and worsen anxiety.
Anxiety can also occur with depression, which commonly causes fatigue too. If you notice low mood or loss of interest as well, tell a professional.
Other Causes of Fatigue to Rule Out
Not all tiredness is anxiety. Fatigue can come from thyroid problems, anemia, sleep apnea, vitamin deficiencies, infections, and some medications. If you are tired most days, it is worth seeing a primary care provider to check for physical causes. A professional can also help sort out how much anxiety is playing a role.
What Helps When Anxiety Leaves You Exhausted
A few steps can help many people:
- Keep a steady sleep routine. Go to bed and wake up at similar times.
- Move your body. Regular activity can reduce anxiety and improve sleep.
- Limit caffeine and alcohol, especially in the afternoon and evening.
- Practice calming techniques, such as slow breathing or grounding.
- Talk to someone. Therapy, including cognitive behavioral therapy (CBT), is a well-supported treatment for anxiety.
These steps do not replace professional care if your symptoms are severe or last a long time.

How to Talk With a Provider About Fatigue and Anxiety
If tiredness is wearing you down, tell your provider the whole story. Describe how long it has lasted, how you sleep, how much caffeine and alcohol you use, and whether you feel anxious, low, or both. Mention any medications or supplements. A provider may recommend a physical exam or lab tests to rule out other causes, and may suggest therapy, skills-building, or medication if anxiety is part of the picture. Being specific helps them recommend a plan that fits you.
