Nutritionist: Dehydration Impacts Brain Function, Focus
Sometimes, feeling foggy or having trouble focusing can be because your brain doesn't have enough water.
Your brain is mostly water and needs it to work well.
When you lose even a little bit of water, it can slow things down.
Drinking just water might not be enough; you also need to eat foods with minerals like salt and potassium, as they help your body use the water properly.
So, if you're feeling tired or can't concentrate, try drinking some water and eating foods with minerals.
This can help your brain work better!
Dehydration, even mild, can impair brain function, impacting memory and focus.
The brain is approximately 75% water and needs fluid for neuron and neurotransmitter function.
Nutritionist Nmami Agarwal says dehydration can be a cause of brain fog.
Hydration involves replenishing electrolytes like sodium, potassium, and magnesium.
Drinking a glass of water is recommended to address dips in energy levels.
