Why Am I Always Tired?

Feeling tired all the time can be frustrating, especially when you're getting enough sleep. While medical conditions should always be ruled out by your healthcare provider, chronic fatigue is often connected to stress, anxiety, depression, trauma, burnout, or poor sleep. As a clinical psychologist, these are some of the most common psychological causes of persistent tiredness that I see.

Can Poor Sleep Hygiene Make You Tired?

The habits surrounding bedtime and sleep, often referred to as sleep hygiene, can have a significant impact on how well we sleep. One example is limiting screen time before bed. The blue light emitted from phones, tablets, and televisions signals to our brains that it is daytime, making it more difficult to fall asleep.

Another important habit is developing a calming bedtime routine. Dimming the lights, avoiding activities that elevate your heart rate, and following a predictable evening routine all help prepare your mind and body for sleep. Creating a comfortable sleep environment—with supportive bedding, a dark room, white noise if helpful, and minimizing stressful reminders—can also improve sleep quality. These seemingly small changes can have a big impact on both your sleep and your daytime energy.

Can Anxiety Make You Feel Tired?

Anxiety activates our body's fight-or-flight response, releasing stress hormones and increasing alertness. While this response is helpful during real danger, living in this heightened state for long periods is exhausting.

Our brains also contain a network called the reticular activating system (RAS), which serves as a type of watchdog while we sleep. Although we are asleep, this system continues scanning our environment for potential threats. If it detects danger, it alerts the rest of the brain and wakes us up.

This is lifesaving during a true emergency. However, people living with chronic anxiety, trauma, or Post-Traumatic Stress Disorder (PTSD) may have a more sensitive alarm system. Small noises or harmless events may be interpreted as threats, leading to frequent awakenings and restless sleep that leave you feeling exhausted throughout the day.

Why Do I Have Racing Thoughts at Night? 

When we lay our heads on the pillow, our minds can suddenly fill with worries. During the day we are distracted by work, family, and countless other demands. But when we finally lie down and those distractions disappear, our minds suddenly have space to revisit everything that happened that day—and everything we're worried about tomorrow.

These thoughts often come with anxiety, guilt, shame, or dread, making it difficult to fall asleep or stay asleep. Poor-quality sleep naturally leaves us feeling tired the next day.

Can Depression Cause Extreme Fatigue?

Depression can drain your energy and make even basic tasks—such as showering, getting dressed, or preparing meals—feel overwhelming. Many people with depression sleep enough, or even sleep too much, yet still wake up exhausted.

Depression can disrupt normal sleep cycles and affect the brain chemicals involved in regulating mood, motivation, and alertness. The brain fog that comes with depression can make it even more difficult to complete basic daily tasks, using more energy. Burnout-related depression may also contribute to persistent fatigue through prolonged stress and hormonal changes. For more information on burnout see my Burnout Blog Post.

Can Processing Emotions Make You Feel Tired?

Whether you have recently been through a traumatic or particularly difficult time, or are working through feelings that first surfaced years ago, processing emotions takes a great deal of energy. Physically, emotions like anxiety and anger trigger the release of stress hormones, which can leave us feeling drained and exhausted. Mentally, activities such as journaling or processing difficult thoughts and feelings also require significant mental effort.

This doesn't mean we should avoid processing our emotions—in fact, I believe the opposite. It simply means we may need extra rest and self-compassion while doing this important work.

What Can I Do If I'm Always Tired?

The good news is that all of these causes of fatigue can improve with the right treatment and support.

• Therapy provides a safe, supportive space to process difficult emotions, experiences, and memories.

• Improving sleep hygiene can lead to better-quality sleep and increased daytime energy.

• Mindfulness practices can help quiet racing thoughts and make it easier to fall asleep.

• Anxiety and depression respond well to Cognitive Behavioral Therapy (CBT) and other evidence-based treatments.

• Poor sleep is one of the hallmark symptoms of PTSD, and evidence-based treatments such as Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT) can be highly effective.

  
  

When Should I See a Medical Doctor About Fatigue?

Persistent fatigue can also be caused by medical conditions such as anemia, thyroid disorders, sleep apnea, nutritional deficiencies, medication side effects, or other health conditions. If your fatigue is severe, new, or persistent, it's important to talk with your healthcare provider.
