What Can Make Fatigue Worse? Identifying Hidden Culprits

5 min read

A 2022 survey found that 13.5% of U.S. adults felt “very tired” or “exhausted” on most days, highlighting the widespread struggle with low energy. If you find your persistent tiredness is worsening, understanding what can make fatigue worse is the crucial first step toward reclaiming your energy.

Quick Summary

Persistent exhaustion can be aggravated by a complex interplay of lifestyle choices, chronic stress, mental health issues, nutritional deficiencies, and underlying medical conditions that require attention.

Key Points

  • Poor sleep quality exacerbates fatigue: It's not just about the hours you sleep, but the quality of that sleep. Insomnia and sleep apnea are common causes.

  • Dietary and nutritional factors are crucial: Deficiencies in nutrients like iron, B12, and D, as well as poor diet choices and dehydration, can significantly worsen fatigue.

  • Chronic stress is a major contributor: Persistent psychological and emotional stress leads to hormonal imbalances and sleep disruption, creating a cycle of worsening exhaustion.

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

  • Underlying medical issues must be ruled out: Conditions such as anemia, thyroid disorders, diabetes, and autoimmune diseases can be the root cause of worsening fatigue.

  • Both too much and too little exercise can harm energy levels: While regular activity is beneficial, a sedentary lifestyle or overtraining can both make you feel more tired.

Fatigue is more than just feeling tired after a long day; it is a persistent and limiting feeling of weariness that interferes with daily life and is often not relieved by rest. While temporary tiredness is a normal part of life, understanding the factors that can intensify and prolong exhaustion is key to managing it effectively. A combination of lifestyle, psychological, and physiological factors can contribute to worsening fatigue.

Lifestyle Habits That Drain Your Energy

Your daily routines can either support or sabotage your energy levels. A closer look at your lifestyle may reveal surprising culprits exacerbating your fatigue.

Sleep Hygiene

  • Poor quality sleep: It's not just about the hours you spend in bed. Poor sleep quality, which can be caused by interruptions or an uncomfortable sleep environment, can leave you feeling unrefreshed.
  • Inconsistent sleep schedule: A fluctuating sleep-wake cycle, common among shift workers or people with jet lag, disrupts your body's natural circadian rhythms, leading to daytime grogginess.
  • Sleep disorders: Undiagnosed or untreated sleep conditions like insomnia, sleep apnea, or restless legs syndrome are major drivers of persistent fatigue.

The Double-Edged Sword of Exercise

  • Too little activity: A sedentary lifestyle can actually decrease your energy levels because it hinders circulation and reduces your body's efficiency at producing energy.
  • Too much activity: Conversely, overexertion can tire you out easily and heighten stress levels, compounding the problem. A balance is needed for optimal energy.

Diet and Hydration

  • Nutritional Deficiencies: Lack of essential nutrients like iron, vitamin B12, and vitamin D is a common cause of fatigue. These deficiencies can impair oxygen delivery and energy production.
  • Poor Food Choices: Diets high in processed foods and sugar cause blood sugar fluctuations, leading to energy spikes and crashes that worsen fatigue. Restrictive dieting can also deplete necessary fuel.
  • Dehydration: Even mild dehydration can significantly impact energy levels and concentration, causing you to feel sluggish.

Caffeine, Alcohol, and Nicotine

  • Excessive Caffeine: While a short-term stimulant, too much caffeine can interfere with sleep, creating a cycle of poor sleep and reliance on more caffeine, which ultimately exacerbates fatigue.
  • Alcohol: As a depressant, alcohol disrupts the sleep cycle and impairs sleep quality, leaving you more tired the next day.
  • Nicotine: This is a stimulant that can negatively affect sleep patterns and energy.

Stress and Mental Health

The connection between your mental state and physical energy is profound. Chronic stress and psychological conditions can be significant factors in worsening fatigue.

The Cycle of Stress and Fatigue

  • Chronic stress: Long-term psychological stress keeps your body in a heightened state of alertness, leading to elevated cortisol levels. This hormonal imbalance can deplete energy and disrupt sleep, creating a cycle that is difficult to break.
  • Emotional exhaustion: Feelings of emptiness and being emotionally drained from prolonged stress manifest as a lack of motivation and persistent weariness.

Mental Health Conditions

  • Depression and Anxiety: These conditions are frequently linked with fatigue. Depression can cause low energy and motivation, while anxiety can lead to racing thoughts that prevent restful sleep.

Underlying Medical Conditions

If lifestyle changes don't alleviate your fatigue, a medical cause may be at play. Many chronic and acute conditions list fatigue as a primary symptom.

Common Conditions

  • Anemia: A lack of red blood cells, often due to iron deficiency, results in reduced oxygen flow and energy.
  • Thyroid Disorders: An underactive thyroid (hypothyroidism) affects metabolism and energy levels, causing significant fatigue.
  • Diabetes: Fluctuations in blood sugar, either too high or too low, can lead to fatigue.
  • Heart and Lung Disease: Conditions like heart failure or COPD reduce the body's ability to supply oxygen, causing exhaustion.
  • Infections: Persistent or post-viral fatigue, such as long COVID, can cause extreme exhaustion that lingers for months.
  • Autoimmune Diseases: Inflammatory conditions like lupus and rheumatoid arthritis often have fatigue as a prominent symptom.

Medications and Their Side Effects

Certain medications can cause drowsiness or interfere with sleep as a side effect, which can worsen fatigue.

Classes of Drugs

  • Antidepressants: While treating depression can help fatigue, some antidepressants can cause or worsen drowsiness.
  • Blood Pressure Medications: Beta-blockers and diuretics can slow heart rate and deplete electrolytes, contributing to fatigue.
  • Antihistamines: Sedating antihistamines can cause sleepiness, and even non-sedating ones can cause fatigue in some people.
  • Pain Medications and Muscle Relaxants: Opioids and muscle relaxants can have a sedative effect.
  • Proton Pump Inhibitors (PPIs): Medications for acid reflux can reduce magnesium absorption, which is vital for energy production.

Comparison: Lifestyle Fatigue vs. Medical Fatigue

Feature Lifestyle Fatigue Medical Fatigue
Primary Cause Poor habits, diet, stress, lack of sleep Underlying illness, deficiency, medication
Duration Often temporary; improves with rest/changes Chronic; persists despite rest/lifestyle changes
Associated Symptoms Mood swings, cravings, trouble concentrating Specific symptoms (e.g., pain, shortness of breath, palpitations, weight changes)
Onset Gradual; linked to a consistent pattern of behavior Can be sudden or gradual, depending on the condition
Resolution Address lifestyle factors and manage stress Requires medical diagnosis and treatment

What to Do When Fatigue Gets Worse

If your fatigue is worsening, it is crucial to investigate the cause. Begin with these steps, but consult a healthcare provider if symptoms persist.

  • Prioritize Sleep: Establish a consistent sleep schedule and practice good sleep hygiene, such as making your bedroom dark and quiet.
  • Adopt an Energy-Boosting Diet: Focus on balanced meals with whole grains, lean protein, and healthy fats while reducing processed foods and sugar. Address any potential nutritional deficiencies with your doctor.
  • Manage Stress Effectively: Incorporate relaxation techniques like mindfulness, yoga, or deep breathing into your routine to combat stress.
  • Move Your Body: Engage in regular, moderate physical activity. Even a brisk walk can boost energy. Avoid overdoing it, which can worsen fatigue.
  • Stay Hydrated: Drink plenty of water throughout the day to avoid the sluggishness of dehydration.
  • Consult a Healthcare Provider: If fatigue is chronic (lasting more than a few weeks), interferes with daily life, or appears alongside other concerning symptoms like pain or weight loss, it's time to see a doctor. They can run tests to rule out underlying medical conditions.

Conclusion

Fatigue is a complex issue, and its worsening can be a sign that something more is at play than simple tiredness. By systematically examining lifestyle habits, managing stress, and addressing any underlying medical issues, you can identify and mitigate the factors making your fatigue worse. A proactive approach, including proper nutrition, exercise, and sleep, alongside medical consultation when needed, offers the best path to restoring your energy and well-being.
