Mental fog: causes and natural solutions

That feeling of a head "in cotton wool", slow thoughts and a capricious memory has a name: mental fog. Rarely serious, it's often the symptom of a lifestyle imbalance. Here are its causes and concrete solutions to regain a clear mind.
What is mental fog?
Mental fog isn't an illness but a set of symptoms: difficulty concentrating, finding words, faltering short-term memory, a feeling of slowness. It fluctuates with fatigue, stress and lifestyle.
The most common causes
- Lack of sleep: the number one cause (see sleep better naturally).
- Chronic stress and excess cortisol.
- Unbalanced diet: sugar spikes, dehydration, deficiencies.
- Digital overload: multitasking and constant notifications.
The natural solutions
The good news: mental fog often clears by acting on the basics. Prioritise sleep, hydration, a diet stable in sugars, physical activity and screen-free breaks. Single-tasking also works wonders.
