That feeling when your brain just isn't firing on all cylinders. You're struggling to concentrate, forgetting things, finding it hard to process information or just feeling mentally sluggish.
We often blame stress, hormones or busy lives, but have you considered how much sleep you're actually getting?
And more importantly, whether you're getting enough REM sleep?
While we're sleeping, our brain is incredibly busy. It's processing information, consolidating memories, regulating emotions and supporting cognitive function.
Here's something interesting…especially if you are a wide awake at 2am person!
Our REM sleep periods get longer as the night goes on. So if you're regularly sleeping for just a few hours, and waking up early, you could be cutting short some of your longest REM periods.
REM sleep plays an important role in memory, learning, emotional processing and problem-solving. So consistently cutting sleep short can mean less opportunity for your brain to carry out these important processes.
This can contribute to brain fog, poor concentration, forgetfulness and feeling more emotionally reactive.
So, what can we do to support our brain?
Aim for 7–9 hours of sleep wherever possible.
Include omega-3-rich foods such as salmon, sardines and mackerel.
Eat magnesium-rich foods such as pumpkin seeds, almonds and leafy greens.
Include protein, eggs, nuts and seeds to provide tryptophan, which the body uses to make serotonin and melatonin.
Enjoy plenty of colourful vegetables and berries.
Be mindful of caffeine and alcohol, particularly later in the day.
Nutrition is important, but don't underestimate the value of simply giving yourself enough time to sleep.
We spend so much time thinking about what we eat, how much we exercise and how productive we are, but sleep underpins so much of our physical and mental wellbeing.
If you're constantly battling brain fog, perhaps it's time to stop pushing through and start looking at the foundations.
Sometimes doing more isn't the answer. Giving your body and brain what they need is.
