What is the reason for the hazy and unclear brain

Unclear brain may be caused by insufficient sleep, excessive stress, malnutrition, dehydration, anemia, and other reasons. It can be improved by adjusting daily routine, psychological regulation, supplementing nutrition, increasing water intake, and seeking medical examination.

1. Lack of sleep

Long term lack of sleep can lead to the accumulation of metabolic waste in the brain, affecting the function of nerve cells. Adults need 7 to 9 hours of sleep per day, and lack of deep sleep can lead to delayed reactions and decreased attention. It is recommended to set a fixed bedtime and avoid using electronic devices before bedtime to create a dark and quiet sleeping environment. A short 20 minute nap during lunchtime can help restore energy.

2. Excessive stress

Chronic stress can continuously stimulate the secretion of cortisol, which can damage hippocampal neurons. Manifested as delayed thinking, decreased memory, accompanied by physical symptoms such as palpitations and hand tremors. Relaxation training such as mindfulness meditation and abdominal breathing can alleviate symptoms, and 30 minutes of aerobic exercise per day can also promote endorphin secretion.

3. Malnutrition

Lack of B vitamins can affect neurotransmitter synthesis, especially when vitamin B1 and B12 are insufficient, brain fog symptoms may occur. Iron deficiency leads to a decrease in hemoglobin's oxygen carrying capacity and insufficient oxygen supply to the brain. It is recommended to consume whole grains, lean meat, and dark green vegetables in moderation, and if necessary, take multivitamin supplements under the guidance of a doctor. 4. Dehydration: When the water content of brain tissue reaches 75%, mild dehydration can affect cognitive function. When fluid loss exceeds 2% of body weight, headaches, drowsiness, and decreased judgment may occur. 1500 to 2000 milliliters of water should be consumed in portions daily, and additional supplements should be taken during exercise or in high temperature environments. The ideal state is when the urine color is light yellow.

5. Anemia

Iron deficiency anemia patients have reduced blood oxygen carrying capacity, and brain tissue hypoxia can cause symptoms such as dizziness and forgetfulness. Excessive menstrual flow and gastrointestinal bleeding are common causes in women. Serum ferritin and hemoglobin indicators need to be tested. After diagnosis, medication such as ferrous succinate tablets and polysaccharide iron complex capsules can be taken according to medical advice, combined with vitamin C to promote iron absorption.

Metabolic diseases such as hypothyroidism and diabetes should be checked if the brain is not awake for a long time. Regular exercise in daily life can help enhance brain blood flow, and the Mediterranean diet pattern can provide abundant unsaturated fatty acids. Avoid excessive reliance on coffee to refresh yourself, and get up and move around for 5 minutes after working continuously for 1 hour. If the symptoms persist for more than two weeks or are accompanied by vomiting and blurred vision, it is necessary to seek medical attention promptly at the neurology department.
