Possible causes of ’brain fog’ or lack of mental clarity include:

1. Stress

Stress is a major factor that can interfere with mental clarity. Chronic stress can result in high blood pressure, weaken the immune system and trigger depression. It becomes increasingly difficult to think, reason and focus when your brain is tired and stressed out.

2. Lack of Sleep

Lack of proper sleep can interfere with mental clarity leading to poor judgment, poor concentration, and cloudy thoughts. 8-9 hours of sleep every day is recommended for sound rest and a clear mind.

3. Diet

Vitamin B-12 deficiency can cause a lack of mental clarity. Allergic reactions to certain foods can also be culprits of triggering brain fog. These include peanuts, aspartame and dairy products among others.

4. Hormonal Changes

Hormonal changes can affect memory, causing short-term cognitive impairment, especially during pregnancy when the estrogen and progesterone levels go up. During menopause, lack of mental clarity, poor concentration, and cloudy thinking are as a result of a drop in the levels of the hormone estrogen.

5. Medical Conditions

Medical conditions associated with fatigue, inflammation or changes in blood glucose levels have the ability to cause mental fatigue.

Other conditions that may cause brain fog to include:

  1. Depression
  2. Diabetes
  3. Migraines
  4. Hypothyroidism
  5. Dehydration
  6. Autoimmune diseases such as lupus and arthritis

The ability of essential oils to target the limbic system directly makes them a powerful tool for treating many mental health ailments including:

  1. Mental clarity
  2. Concentration and focus
  3. Memory
  4. Brain fog
  5. Brain damage
