Why Am I More Tired Than Usual?

Fatigue is a common symptom experienced by individuals in today’s fast-paced world. While tiredness can be a result of overexertion or lack of rest, it can also be caused by underlying health issues. This article aims to provide an overview of the possible causes of fatigue and why someone might be more tired than usual.


Fatigue is a feeling of extreme tiredness, exhaustion or low energy, that cannot be remedied with rest or sleep. It is not a disease but rather a symptom that can be indicative of an underlying medical condition. Fatigue can be acute or chronic, with chronic fatigue lasting for longer than six months and often having a significant impact on daily activities.


There are numerous factors that can contribute to feelings of tiredness. These may include:

Lack of Sleep: One of the most common reasons for feeling tired is simply not getting enough sleep. The National Sleep Foundation recommends adults get between 7 and 9 hours of sleep per night.

Sleep Disorders: Some sleep disorders, such as sleep apnea, can disrupt the quality of sleep and result in chronic fatigue.

Physical Activity: Overexertion, especially from prolonged or intense physical activity, can cause muscle fatigue and overall tiredness.

Dehydration: Lack of fluids can lead to low energy and feelings of tiredness.

Poor Nutrition: A diet lacking in essential nutrients and vitamins can contribute to fatigue.

Mental Health: Mental health conditions such as anxiety and depression can cause significant fatigue, even if adequate sleep is achieved.

Medications: Certain medications, including some antidepressants, antihistamines, and blood pressure medications, can cause fatigue as a side effect.

Underlying Health Conditions: Chronic fatigue can be a symptom of underlying health conditions such as anemia, thyroid disorders, diabetes, heart disease, or autoimmune disorders.

Why Am I More Tired Than Usual?

If someone is experiencing fatigue that is more severe or persistent than usual, it may be a sign of an underlying health condition or lifestyle factor. Some potential reasons for increased fatigue include:

Stress: Increased levels of stress can lead to mental and physical exhaustion.

Chronic Fatigue Syndrome (CFS): CFS is a debilitating disorder that causes severe fatigue, sleep disturbances, and other symptoms. The exact cause of CFS is unknown, and it can take time to diagnose.

Sleep Apnea: Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep, leading to disrupted sleep and daytime fatigue.

Anemia: Anemia is a condition in which there is a deficiency of red blood cells or hemoglobin in the blood. This can cause fatigue due to decreased oxygen-carrying capacity of the blood.

Hypothyroidism: Hypothyroidism is a condition in which the thyroid gland does not produce enough hormones, leading to fatigue, weight gain, and other symptoms.

Depression: Depression is a mental health condition that can cause fatigue and feelings of hopelessness.

Chronic Pain: Chronic pain conditions such as fibromyalgia and arthritis can cause significant fatigue due to disrupted sleep and constant pain.

Cancer: Cancer and its treatment can cause fatigue due to the body’s response to the disease and treatments.


Fatigue is a common symptom that can have numerous causes, ranging from lifestyle factors to underlying health conditions. While occasional tiredness may not be a cause for concern, persistent fatigue that interferes with daily activities may be a sign of an underlying issue. It is essential to consult with a healthcare professional if fatigue is persistent or severe.
