Tired so fast

Do you get tired a lot and fast? Do you feel permanently exhausted and don’t know why? There are endless causes for which this exhaustion occurs. A lack of adequate oxygenation, poor eating or sleeping habits, chronic or very severe diseases can be some reasons.

Below, in this FastlyHealarticle, you can find answers to your question: why do I get tired so fast?

Lack of adequate rest

There are many medical, physical, and mental conditions that can cause exhaustion, fatigue, or exhaustion from minimal or daily activities, and one of the most common is lack of sleep.

Different reasons can make your rest insufficient: having insomnia, sleeping fewer hours than the body needs, non-restorative sleep, suffering from sleep apnea, reversed schedules (sleeping during the day, being awake at night). Night).

It is essential to rest well and at the correct times. The body is regulated by certain hormones, such as melatonin or cortisol, secreted in different amounts according to sunlight and hours of sleep.

Jet lag

This problem deserves a separate description. There is talk of jet lag when there is a disruption in the rhythm of sleep and wakefulness due to a long-haul flight.

Your body is used to a routine, and when changing time zone, your body may want to continue its rhythm, but there is a contradiction between day and night.

Thyroid problems

A thyroid condition can make it difficult to fall asleep or stay asleep. Both hiccups and hyperthyroidism can cause these types of disorders.

On the other hand, hypothyroidism usually puts the person in a low energy state, which can cause significant fatigue even when doing little activity.

Heart failure

It is a problem in which the heart does not work correctly. This makes sending oxygenated blood to the different tissues that depend on it challenging.

The brain, lungs, muscles, and the rest of the body will have less oxygen availability. It’s more than enough reason for you to tire out quickly.

In severe cases, fatigue appears even with minimal daily life activities.

Respiratory problems

Different respiratory diseases can make you tired very quickly. Among the most frequent, they can be cited for example:


This problem in the blood causes adequate oxygen to reach the body. Among the symptoms caused by anemia are:

  • Exhaustion.
  • Shortness of breath.
  • Headaches.
  • Dizziness

In the following article, we explain the symptoms, types, and treatment of anemia in more detail.

Alcohol, tobacco, and drugs

Excessive alcohol consumption can cause problems at all levels of the body, from severe liver problems to encephalopathy (a nervous system disease). When consumed in high amounts, your metabolism demands a lot of energy. The residues of this transformation in the body can cause headaches, fatigue, dizziness, among other symptoms. On the other hand, dehydration is common.

Smoking can also cause sudden fatigue. On the one hand, nicotine stimulates the nervous system, leading to exhaustion. On the other hand, it can cause lung problems that hinder adequate oxygenation of the body.

The drug “recreational” may also cause organic wear fatigue, making it a fairly common symptom.


Some medications prescribed by professionals can cause more fatigue and sleep than usual, such as:

  • Antihistamines.
  • Pseudoephedrine.
  • Cholesterol medication.
  • Antidepressants
  • Neuroestimulants (methylphenidate, modafinil).
  • Adrenalin.
  • Drugs for the heart and circulation (diuretics, antiarrhythmics, antihypertensives).
  • Corticosteroids.
  • Antiparkinsonianos.
  • Bismuth.

On the other hand, some natural herbs can also generate a specific state of drowsiness, and this is the case of:

  • Balm.
  • Valerian.
  • Pasionaria.

Sedentary or exaggerated physical effort

The lack of movement and physical activity can make you fall into a vicious circle. The less you do, the more tired you will be to perform tasks that require little energy.

On the other hand, obesity is also a significant factor that can make it difficult for you or tire you faster when doing activities.

Exercise, no matter how little, causes the body to secrete endorphins. These are known as the “well-being” or “happiness hormones,” They can make you feel much better after taking a walk, dancing, or whatever you like.

Both too little exercise and too much physical activity are detrimental to health. Subjecting yourself to exhausting physical activity sessions on an ongoing basis also generates wear and tear that is difficult to recover.

Lack of incentive or not finding motivations in your activities can put you in a significant state of low energy, physical, and mental fatigue.

Bad eating habits

If your diet is heavily loaded with unhealthy foods, your body has an extra demand for energy to metabolize them. Processed products, excess meat, refined products (white flour, sugar, salt), fried foods are some products that you should avoid.

Likewise, excess substances that alter the sleep cycle can cause fatigue. It is the case of:

  • Café.
  • Cola sodas.
  • Chocolate
  • Black tea.

The amount of food can also cause weakness and fatigue. Eating too little or too much for your nutritional requirements can cause these symptoms.

Stress or psychiatric problems

Lack of mental rest can put you in such a state of exhaustion that even the most minor efforts will make you tired.

Stress can precipitate sleep problems, metabolic disorders, psychological and organic problems of all kinds.

Depression, anxiety disorders, or other psychiatric problems can cause fatigue or tiredness from small activities.
