Fatigue Symptoms

Have you been feeling like your get up and go has got up and went? You are not alone, at all. Many individuals complain of fatigue after those energetic years of childhood, when we could eat everything, sleep anytime, and had unlimited free time full of play and freedom from all worry of bills, work, and kids.

Fatigue can be caused by many factors in our modern world. Blue light robs us of sleep quality and quantity; environmental toxins impact hormones that regulate sleep, and technology flies at us so fast it creates levels of sleep we cannot even fathom anymore, constantly assailing us with new, email, and—again, more blue light.

Fatigue is not only by excesses in lifestyle factors such as blue light and stress but also lacks—you may feel fatigued, for example, if you're not exercising, eating right, or taking care of yourself.

The symptoms of fatigue are quite obvious and include feeling:

  • Sleepy
  • Tired
  • Weak
  • Unable to start or participate in usual activities
  • Unable to concentrate
  • Forgetful
  • Emotionally drained/moody
  • Nothing to do sounds like such a great idea
  • Feeling like your bones feel leaden

Fatigue symptoms affect our abilities to function in our daily lives, impacting work, school and family. Let's review some of the common causes of fatigue, and what you can do to overcome fatigue.

Fatigue Causes Overview

  • Poor sleep hygiene/sleep deprivation: Sleep hygiene refers to habits that affect the quality of your sleep. Sleep hygiene means being a selfish sleeper, prioritizing sleep, eliminating lights and even digital clocks from your room, sleeping in complete darkness, avoiding late night eating that will disrupt sleep, and trying to get to bed early so you can get 8 to 9 good, deep restorative hours of sleep.

  • Infection: Any infection—fungal, viral, or bacterial—can cause fatigue. Fighting illness or disease requires a lot of energy. The fatigue symptoms associated with illness is our signal to slow down. Sleeping during illness improves both recovery and survival rates. Sure, you can push through feeling "sick and tired," but chances are, you will just feel sicker, longer.

  • Depression : Fatigue (both mental and physical) can be a symptom of depression. With depression, this loss of energy and feeling of exhaustion often persists even if you have adequate sleep. Some people with depression have bursts of enthusiasm and exuberance, but it is more common to have a loss of energy and great feelings of listlessness and lethargy.

  • Hypothyroidism: The thyroid is a gland that produces the hormones that regulate temperature and metabolism. Metabolic changes caused by hypothyroidism will cause fatigue because when the metabolism slows, your manufacturing of energy slows as well as you are not processing food into energy.

  • Lack of exercise/movement: Exercise gets your heart rate up, which will help you feel peppy and energetic. It also heals much of the damage that is done by sitting for long periods of time—and sitting, as you might have heard, is now being deemed more harmful to the body than smoking.

  • Medications: Individuals who take medications such as bi-polar medications or medications for allergies, arthritis, and fibromyalgia often complain of fatigue, as these medications tend to make you feel very tired/sleepy.

  • Vitamin and mineral deficiencies: Being deficient in minerals like iron or vitamins such as the B vitamins, such as B-12, can cause great feelings of fatigue.

Fatigue Treatments and Relief

To avoid fatigue, sleep experts recommend:

  • Sleeping and waking on a regular schedule
  • Eat a very balanced diet rich in plants antioxidants, and energy-yielding phytonutrients and amino acids—a balanced diet will help address any nutritional deficiencies that might be causing fatigue
  • Avoiding caffeine, especially in the afternoon (it will only disrupt sleep quality, even if you are sleeping long periods of time)
  • Avoiding alcohol and sleeping pills (these stimulants/drugs ruin sleep quality)
  • Avoiding all blue light-emitting devices during the two to three hours before going to bed
  • Use black-out curtains to eliminate all light that might filter through windows, waking you up and inhibiting sleep quality
  • Avoiding long afternoon or evening naps
  • Exercising in the morning or afternoon, but not in the evening
  • Getting sun exposure in the mornings. Early morning sun exposure tells your body it's daytime now and helps your circadian rhythms "set" so your body will better recognize nighttime as well!
  • Avoiding eating too close to bedtime (within two hours)
  • Sleeping in a cool room

You should seek immediate medical care if you have fatigue and:

  • Symptoms of depression
  • Fever
  • There is no improvement despite adequate sleep
  • Think you might have been bitten by a tick

FAQs About Fatigue

Here are some frequently asked questions about fatigue.

Why am I so tired?

Fatigue can be caused by many things. Major causes may include psychological disorders (e.g. depression, anxiety, malnutrition), drugs (e.g. antidepressants, drug abuse, withdrawal, addiction), endocrine-metabolic disorders (e.g. hypothyroidism, diabetes), cancers, infections, cardiopulmonary diseases (e.g. chronic heart failure, COPD), rheumatoid disease, and disturbed sleep.

What are the symptoms of fatigue?

Fatigue can be manifested as difficulty or inability initiating activity (feeling generally weak); reduced capacity maintaining activity (tiring easily); and difficulty with concentration, memory, and emotional stability (mental fatigue). Tiredness, lack of energy, and excessive sleepiness are frequently used to describe fatigue.

Why am I sleeping so much?

Many causes can contribute to excessive sleepiness, which include insufficient sleep, sleep disorders (e.g. sleep-related breathing disorders or sleep-related movement disorders), medications (e.g. benzodiazepines, non-benzodiazepine sedatives, or antihistamines), certain neurological disorders (e.g. Parkinson disease), genetic disorders (e.g. Prader-Willi syndrome), medical conditions (e.g. hypothyroidism or obesity), and psychiatric disorders (e.g. depression or anxiety).

Why do I feel so weak and tired?

A variety of systemic disorders can give you the feeling of weakness without making you truly weak, which include cardiopulmonary (heart/lung) disease, joint disease, anemia, body wasting due to malignancy/chronic infectious or inflammatory disease, depression, and fatigue. Causes for primary muscle weakness include muscle diseases (myopathy), and damages to various parts of the nervous system.

What is chronic fatigue syndrome like?

Key features include easy fatigability and difficulty concentrating, and are often associated with additional symptoms (e.g. difficulty sleeping and muscle aches). Onset is often sudden and associated with a typical infection such as an upper respiratory infection or mononucleosis (mono). Excessive physical activity typically exacerbate the symptoms.
