Many other conditions may lead to tiredness. It’s important to understand that several factors may contribute to your exhaustion.
Here are a few other common reasons why you may feel tired:
- Drug and alcohol dependence: People who are dependent on drugs or alcohol are more likely to experience fatigue.
- Shift work: Shift work causes sleep disruption and may result in fatigue.
- A less active lifestyle: Leading a less active lifestyle may lead to tiredness during the day. Getting regular physical activity may decrease overall fatigue.
- Certain medications: Some drugs, including steroids, blood pressure medications, and antidepressants, are linked to side effects like insomnia and increased tiredness.
If you’re consistently feeling tired, here are a few steps you could consider taking:
- Track your symptoms to identify trends or possible lifestyle factors that may be affecting your sleep or energy levels.
- Try adjusting your sleep environment to help you wind down before bed and potentially sleep better.
- Connect with a healthcare professional, such as a primary care doctor or sleep medicine specialist, who can help you pinpoint possible causes and recommend the appropriate management plan.
Even though everyone has days when they feel exhausted, constantly feeling run down and tired isn’t normal.
Many possible factors cause chronic fatigue, such as underlying medical conditions, nutrient deficiencies, sleep disturbances, caffeine intake, and chronic stress.
If you’re experiencing unexplained fatigue, you must talk with your doctor to find the cause.
In many cases, your fatigue should improve once you identify the underlying cause(s) and make appropriate lifestyle and dietary adjustments — or get the right treatment for medical conditions.

Work with a doctor you trust to get the right testing to rule out common health conditions that may be contributing to your fatigue.
