why am I so tired

Ever find yourself asking, “Why am I so tired all the time?” Don’t worry, you’re not alone. Approximately 60% of adults in the US feel the same. Ever since the onset of the COVID19 pandemic, many people claim that they feel exhausted almost all the time. Some blame it on the pandemic, claiming that working from home has disrupted their sleep schedules.

Others blame it on physiological factors, too much screen time, and not having a routine. Regardless of the causes, it’s clear that more people feel fatigued than ever before.

Call it daytime sleepiness or chronic fatigue – these types of feelings are very damaging & frustrating. Exhaustion isn’t evident to others. It’s not something that doctors can test for & measure in a physical exam. But, “pushing through” the exhaustion & frustration is not the answer. 

By learning about the information presented in studies, individuals can develop their strategies & tackle their fatigue-related problems. Let’s assess everything science has to say about chronic fatigue and how it can be prevented.

Why Am I So Tired?: What are Tiredness and Fatigue?

In materials science, fatigue is the cumulative weakening effect that ultimately destroys an object or material. Repeated applications of stress can weaken any material. For example, thermal fatigue often causes industry-grade equipment to lose its utility. Similarly, athletes experience muscle fatigue when they exercise too much.

The term “chronic fatigue” is used to describe a similar effect that humans experience both in their bodies & their minds. Small things add up to cause immense stress to the human mind & body. People who experience fatigue are often accused of having naturally low energy levels or no motivation. But, that’s not always the case.

Types of Fatigue

If you’re feeling tired all the time, physically & psychologically – there might be deeper issues at play. Here are three types of fatigue that people typically experience:

Transient Fatigue

People experience this form of acute fatigue when they get bad sleep for 1 to 2 days.

Cumulative Fatigue

This type of fatigue is more intense. It happens when people get inadequate sleep for multiple days over a few months.

Circadian Fatigue

Typically, people with sleep disorders like obstructive sleep apnea experience this type of fatigue at night. The circadian rhythm of someone with such a disorder will go through lows during nighttime.

Categories of Fatigue

People who don’t feel tired all the time but only in certain circumstances categorize this condition in other ways. Their categories include:

Social Fatigue

Feeling tired and unmotivated in social settings. Social fatigue often makes people feel overwhelmed which negatively affects their energy levels.

Emotional Fatigue

Poor sleep quality coupled with sadness, anger, & frustration can cause people to feel emotionally fatigued. Such people are highly prone to depression and other mental health problems.

Physical Fatigue

Joint pain, muscle spasms, and other forms of pain that people experience after engaging in physical activities. Surprisingly, this type of fatigue is the easiest to fix.

Mental Fatigue

People who expend a lot of mental energy throughout the day are likely to experience mental fatigue. Be it exams or personal relationships – any mentally intensive activity can cause this type of fatigue.

When people experience these forms of chronic fatigue for over six months, they’re diagnosed with chronic fatigue syndrome (CFS).

Also known as “Myalgic Encephalomyelitis,” this long-term condition has many symptoms. The most common being extreme tiredness. It can happen to anyone. Patients must exhibit some symptoms for at least six months or longer to be clinically diagnosed with chronic fatigue syndrome.

What are the Symptoms of Chronic Fatigue Syndrome?

Just like having flu-like symptoms doesn’t mean you have the flu, simply feeling tired isn’t enough for getting diagnosed with CFS. Chronic tiredness has many basic symptoms that may or may not indicate chronic fatigue. They include:

Symptoms of Chronic Tiredness
Sore muscles
Low motivation
Reduced ability to pay attention to the situation at hand
Poor concentration
Short-term memory problems
Blurry vision
Reduced immune system function
Appetite loss
Unexplained weight gain or loss
Impaired hand-to-eye coordination
Impaired decision-making and judgment
Slowed reflexes & muscle weakness

To establish a diagnosis of Chronic Fatigue Syndrome, people must exhibit the following symptoms (in addition to the above-mentioned symptoms) as well:

Symptoms to Diagnose Chronic Fatigue Syndrome
Impaired memory
High blood pressure
Inability to get more than 5 to 6 hours of sleep
Severe muscle pain and cramps
Multi-joint pain (without swelling or redness)
Chest pain
Shortness of breath
Bleeding (e.g., vomiting blood or rectal bleeding)
Severe pelvic, back, or abdominal pain
Severe headaches
Irregular heartbeat
New lumps appearing in the body
Fever (greater than 101℉ or 38.3℃).
Abnormal vaginal bleeding for females
Unexplained pain points all across the body
Tender lymph nodes (cervical or axillary)

Anyone exhibiting four/five of these symptoms for six months or more mustn’t waste any time visiting healthcare professionals. CFS can affect anyone – from children to senior citizens. In the current era, it’s more common in people between the ages of 20 and 40.

What Causes Chronic Fatigue?

There are many potential causes of fatigue. Not getting enough oxygen while sleeping, nutritional deficiencies, pre-existing health conditions, and even certain medications can cause excessive tiredness. Typically, people with CFS use a lot of mental energy. They tend to overthink certain things.

By the time their minds are thought, there’s the inevitable crash and they feel fatigued. These people may not have chronic illnesses. So, understanding this type of fatigue is rather difficult for them. This is further complicated by the fact that we’re all prone to overthinking at different points in our lives.

This type of mental fatigue occurs in normal, healthy people all the time. It’s a normal response to mental or physical exertion. But, “normal” fatigue becomes “abnormal” or “chronic” when its effects are prolonged. For example, the lack of restful sleep for a few days will depreciate the quality of blood flow your brain receives.

If you drink too much caffeine in such circumstances, the prolonged period of mental exertion will make you feel fatigued. This fatigue is a normal response to your temporary lifestyle.

But, if it lasts more than a few days, (more than 48 to 72 hours), it can become abnormal or chronic.

In a recent survey, thousands of people with no medical history of insomnia, sleep apnea, and other sleep-related conditions were asked about the energy-depleting activities in their life.

Most of their symptoms can be traced back to poor habits, routines, & sedentary lifestyles.

6 Main Lifestyle Factors that Contribute to Fatigue and Tiredness

  1. Excessive alcohol or drug use
  2. Engaging in intense physical or mental activities unchecked for long periods
  3. Irregular Exercise
  4. Not getting enough sleep daily
  5. No strict rules regarding the use of technology in bed
  6. Unhealthy diet & not eating food on time

If these lifestyle choices are causing you to sleep problems and fatigue, take an honest inventory of them. Addressing these mistakes is the first step toward relief. Fatigue may also be related to an underlying health condition.

Taking certain over-the-counter medications to address certain health conditions may also cause fatigue. For example, unrelenting exhaustion is a common side-effect of taking blood pressure medications for the first time.

Here are some other conditions that are commonly related to fatigue:

  • Acute liver failure
  • Iron deficiency or Anemia
  • Depression & anxiety disorders
  • Cancer
  • Chronic infections
  • Hyperthyroidism (Thyroid hormone deficiency where too many thyroid hormones are produced in the body)
  • Hypothyroidism (when the underactive thyroid gland fails to produce enough thyroid hormone)
  • Chronic inflammation
  • Chronic kidney disease
  • Severe nutritional deficiencies (e.g., severe vitamin D deficiency can cause osteoporosis & fatigue)
  • Chronic Obstructive Pulmonary Disease (COPD)

Consuming heavy medications, such as those used during chemotherapy or to treat heart disease can also cause severe fatigue. But, the doctors who administer these drugs let their patients know about these fatigue-related risks.

A fatigued body and mind are extra prone to sicknesses. People who feel tired all the time generally have weakened immune systems. So, seeking proper treatment from medical professionals is a must for anyone with these underlying health conditions.

Treating & Preventing Chronic Fatigue

The prognosis for fatigue is surprisingly good. There are both prescription and non-prescription drugs & supplements in the market that can help treat chronic fatigue syndrome. There are several natural remedies for patients to try out as well.

More importantly, physical and mental fatigue prevention is an easily achievable task. In most cases, preventing the underlying cause instantly prevents symptoms of fatigue from getting stronger. Here are some valuable fatigue prevention techniques.

Natural Remedies

Manage day-to-day stress by practicing mind & body relaxation techniques.


Exercising regularly as per your body’s fitness levels. Set a fixed time to exercise. Make a habit of exercising every day at that fixed time.

Proper Medication

Ask your health care practitioners or pharmacist about the medications you’re consuming and their potential side effects.

Improve your diet

Add more fruits and vegetables to your diet. Always start the day with a heavy breakfast. Consume as much whole grain, leafy greens, milk, and other sources of vitamins & proteins as possible.

Avoid too much caffeine

Avoid consuming too much caffeine. Cut out coffee, chocolate, chewing gum, and energy drinks that contain large amounts of caffeine from your diet. If you do drink a few cups of coffee, tea, or other caffeinated drinks, don’t drink them after 5 pm.

Stop smoking

Avoid smoking & drinking alcohol, especially after dinner. The use of nicotine and alcohol within four to five hours of bedtime leads to poor sleep quality.

Be intimate with your partner

Engage in physical intimacy with your partner as frequently as possible, especially right before going to sleep.

Get enough sleep

Get a good night’s sleep by going to bed at a fixed time every night.

Anyone can reduce the symptoms of fatigue by taking these steps. Even those with underlying medical conditions. Of course, people with serious medical conditions like COPD or diabetes must work with healthcare professionals to optimize their treatments.

For example, if taking certain medications is causing you fatigue, your doctor should remove these drugs from your treatment plans. Treatment of fatigue depends solely upon the factors causing this problem.


Fortunately, not all fatigue treatment procedures involve prescription drugs. There are many vitamins, minerals, and all-natural supplements that can fix fatigue without getting the patients addicted (unlike caffeine-based products). Here are some of them:

Vitamin B12

Vitamin B12 plays two major roles in the body. It helps form red blood cells that transport blood & oxygen throughout the body. It also supports various neurological functions in the brain. According to theNational Institute of Health, people with vitamin B12 deficiency face greater risks of fatigue & physical/mental weakness. Cooked clams, steamed mussels, & cooked salmon are some of the best natural sources of vitamin B12.


Responsible for 300+ different biochemical reactions in the body, Magnesium is an essential mineral. From nerve function to energy production to blood glucose control – this mineral facilitates many key functions in the body. People with magnesium deficiencies are likelier to experience fatigue & sleep problems. Leafy green veggies (e.g., kale, okra, etc.) nuts, dry beans, & whole grains are all good natural sources of Magnesium.


Calcium facilitates the production of melatonin in the body. Melatonin is the ingredient that keeps the body in a calm state so that people can stay asleep for longer. Milk, cheese, and drinks with added calcium are good natural sources of calcium.

While these natural vitamins and minerals are great for treating fatigue, they can also be hard to access. For example, most vegans are inherently low on vitamin B12 because this vitamin is only found in animal products.


Similarly, finding & consuming calcium or magnesium-rich products regularly isn’t feasible for many people. That’s where supplements can be of immense help. Here are some of the best all-natural supplements for treating fatigue & improving your energy levels:
