Brain fog and tiredness: causes and symptoms

Are you suffering from brain fog and you have a tired and fuzzy head, but you don’t know it? Surely many times you are performing a task, and you try to concentrate but can’t. Besides, you may try to remember the person you met last night, and you can’t. Or maybe you are feeling tired.

You may want to boost your energy and memory capacity!

Don’t worry, what you are suffering from is not Alzheimer’s. In this post we tell you all about brain fog, and a tired and fuzzy head.

What is brain fog?

Brain fog is a cognitive dysfunction, one of the problems unknown by society but latent among the population. It is a cognitive dysfunction that can have a very big impact on your life.

Brain fog and tiredness go hand in hand, since it is not a lack of attention or forgetfulness, it is a brain alteration that puts the brain on “pause” and distorts reality.

When a person suffers from brain fog, the brain does not have enough energy to perform daily activities. Usually the person goes blank.

Symptoms of brain fog and a tired and fuzzy head

A person showing signs of brain fog may experience one or more symptoms:

  • Memory loss: it is very common to forget simple information, such as the name of a person, or a recent conversation you just had with someone. In this case it is difficult for the person to retain information and the forgetfulness is usually short term.
  • Lack of comprehension: when reading or when someone is explaining or commenting on something. This is because the brain feels fuzzy and is not able to assimilate the content to which it is being exposed.
  • Slowness of thought: because of the inability to concentrate, thoughts and responses are slower than usual.
  • Disorientation: even in places known or frequently traveled by the person. A person suffering from mental fog and headaches has difficulty thinking which way to go.
  • Low energy or fatigue: because tasks that require mental effort are more complicated to perform, this causes higher levels of fatigue.
  • Temperamental changes: because of a tired and fuzzy head, you do not control your emotions, and your mood changes constantly in response to external factors.
  • Lack of nutrients: a lack of nutrients such as Vitamin B12, Vitamin D, Omega-3 and Magnesium can lead to increased fatigue and concentration problems.

Causes of brain fog 

  1. Too little sleep: sleep routine is essential, because without adequate rest, your brain will not be able to function at 100% of its capabilities. It is very normal not to have energy or not to think clearly.
  2. Stress: when you overload your body with cortisol, it weakens your body and increases blood pressure causing a tired and fuzzy head. Causing you to be stressed and unable to think clearly. Oxidative stress is another enemy you should have in mind.
  3. Lots of processed foods: diets high in processed foods and low in vitamins can cause you to suffer from mental fog and headaches.
  4. Allergies or intolerances: intolerance to certain foods or for example gluten is said to restrict brain performance.
  5. Dehydration: if the importance of drinking at least 2 liters of water a day is constantly mentioned, there is a reason. Dehydration causes a lack of optimal brain performance.
  6. Lack of exercise: if you don’t exercise much, your brain doesn’t get enough blood. Even a 20-minute walk can increase your cognitive performance.
  7. Hormonal changes: changes in hormone levels can affect short-term memory and cognitive functions. This tends to happen more during pregnancy or menopause.

For a better diagnosis, we always recommend seeing a specialist. So that he/she can give you a more accurate answer. Furthermore, as to the source of the symptoms you are suffering from and what it is.

Solutions for mental fog and fuzzy head 

Solutions for mental fog depend on the causes of the fog. But the following are the most common solutions for treating brain fog:

socializing against brain fog
  • Healthy sleep habits: for example, always going to bed at the same time can provide you with balance and stability. We recommend sleeping 7-8 hours a day. 
  • Manage stress: this is not an easy topic to deal with. Try to reduce the pressure you are under on a daily basis. Organize yourself and rest the necessary time between activities, don’t multitask!
  • Eat healthy: A balanced diet helps your brain get its supply of amino acids and essential fatty acids. You can also rely on brain supplements. Always under the guidance of a specialist.
  • Exercise: exercise produces hormones that help clear the brain, improve mood and enhance cognitive function. You can start exercising slowly and progressively.
  • Socialization: going to events or having conversations with people provides both emotional health and positive stimuli for your brain, maintaining constant mental activity. In this way, mental deterioration caused by too little mental activity is avoided.
  • Challenge your mind: constantly challenge yourself by trying new activities, thus stimulating your mind. 
  • Avoid alcohol or substance abuse: if we are avoiding negative effects on your mind, the last thing you want is to introduce substances that affect your brain into your body.
