Brain fog is a term you may have used before to describe a moment where you forget what you were saying or doing but it could be a symptom of a more serious medical condition.

Brain fog can be associated with issues like memory problems, poor concentration, fatigue and more.

What are the reasons for brain fog?

1 You’re not sleeping

Poor quality sleep can be one of the main reasons you’re struggling to concentrate at work and in day to day life. Try and aim for at least eight hours each night and get into a routine to help your brain relax.

2 You are really stressed

Stress is another big factor when looking at reasons for brain fog. Stress is so much more than mental, it can weaken your immune system, leave you feeling exhausted and affect your psychical and mental capabilities. Try and find ways to relax like eating and exercising.

3 You have a poor diet

Certain nutrients and vitamins such as Vitamin B-12 support healthy brain function and without them, you may find it hard to focus. Try and give your body a healthy, balanced diet. Listening to what your body needs is really important, especially if you have allergies.

Eating foods that provoke your allergies can give you brain fog so it’s best to avoid these too.  

4 You might be taking the wrong medication

If you’ve recently started taking medication and feel dazed out or start noticing brain fog, this could be the reason. Speak to your doctor to see if there are any alternatives to help overcome this.

5 You’re going through hormone changes

Hormone changes can also play a key part in contributing to brain fog. If you’ve heard the term ‘baby brain’ you’ll know this means women who are pregnant tend to experience brain fog due to a rise progesterone and estrogen hormones during pregnancy. This also affects women who are going through the menopause, as a drop in estrogen levels can also cause a lack of concentration.

6 You have a big life change coming up

While daily stress can cause brain fog, so can significant life events such as getting married or moving home. Bigger events can distract you from your day to day responsibilities and cause you to ‘space out’ and think more about future events than focus on your immediate life. Try prioritising and writing lists to stay organised and keep on top of everything.

7 You have a medical condition

If you find you’re still experiencing brain fog, it’s time to visit your doctor to discuss if you have a medical condition. Remember, brain fog is a symptom of a bigger problem and this can be associated with:

  • Chronic fatigue
  • Fibromyalgia
  • Dehydration
  • Anaemia
  • Depression
  • Migraines
  • Alzheimer’s disease
  • Autoimmune diseases such as lupus, arthritis, and multiple sclerosis
