Brain fog and fatigue: What is it and what to do about it

Uppdaterat: 5 aug. 2023


Brain fog and fatigue is a common and weary consequence of stress. When we experience prolonged stress, our bodies release stress hormones, such as cortisol. This stress response is a natural mechanism that helps us deal with dangerous situations, but if it is activated too frequently or for prolonged periods, it can have negative effects on our health, including brain fog and fatigue.

What are the symptoms?

Brain fog during stress is a sense of mental exhaustion, blurred vision, and difficulties in focusing or concentrating. It can also involve memory problems and impaired cognitive function. These symptoms can be frustrating and impact our daily life, work performance, and relationships.

It can involve basic things like not remembering which toothbrush is your own or having trouble recalling where a specific product is located in a store. The examples are numerous. These are symptoms of brain fatigue: 1. Memory problems

2. Trouble focusing 3. General impaired cognitive ability


The causes of brain fatigue during stress are complex and involve both psychological and physiological factors. When we are stressed, the activity in the sympathetic nervous system increases, leading to an elevated production of stress hormones such as cortisol and epinephrine. This hormonal imbalance can affect the neurotransmitter system in the brain as it can disrupt the normal functioning of brain circuits and impair cognitive processes.

Stress can also negatively affect sleep, further exacerbating brain fatigue. Sleep is crucial for the brain and body to recover, and lack of sleep can result in cognitive and concentration problems.

What can you do about it?

To manage brain fatigue during stress, it's important to take care of yourself and prioritize recovery. Here are some tips that can help:

1. Stress management: Learn to manage and reduce stress through techniques like deep breathing, mindfulness, or yoga. This can help calm the brain and alleviate brain fatigue.

2. Sleep: Establish a regular sleep routine and ensure you get enough quality sleep each night. Avoid caffeine and electronic devices before bedtime.

3. Regular exercise: Physical activity releases endorphins and improves blood circulation, which can provide a mental energy boost and reduce brain fatigue.

4. Healthy diet: Eat a nutritious diet rich in omega-3 fatty acids, antioxidants, and vitamins. These nutrients can support brain function and reduce brain fatigue.

5. Recovery time: Schedule regular breaks and recovery periods throughout the day to give your brain a chance to rest and recover.

If brain fatigue during stress persists or worsens, it's important to seek professional help from a doctor or therapist.
