Effective strategies to regain mental clarity
Establish routines with active breaks
Working non-stop might seem productive, but it’s actually the opposite. Taking 5 to 10-minute breaks every 60–90 minutes helps your brain reset and prevents cognitive overload. Stand up, breathe, stretch, or simply disconnect from the screen to improve your focus.
Optimize your sleep
Poor sleep or sleeping less than 6 hours reduces your ability to concentrate and remember. Create a nighttime routine without screens at least 1 hour before bed, use dim lighting, and make sure your room is cool and quiet. Sleeping well is key to mental recovery.
Support your brain with functional foods
Your brain needs clean energy and key nutrients. Include foods rich in omega-3s (like salmon and chia seeds), antioxidants (blueberries, spinach), and healthy fats (avocado, nuts). Avoid ultra-processed foods, refined sugars, and alcohol.
Reduce quick dopamine consumption
Social media, video games, or uncontrolled scrolling create artificial dopamine spikes that, over time, exhaust your reward system. Limit these sources, set schedules, and replace passive habits with activities that bring real satisfaction.
Exercise regularly
Exercise not only improves your physical condition but also activates neurotransmitters like serotonin and dopamine. Just walking for 30 minutes a day, doing yoga, or dancing is enough. Your mind will thank you almost immediately.
Breathe deeply
Diaphragmatic or conscious breathing activates the parasympathetic nervous system, which is responsible for calming the body. Try inhaling for 4 seconds, holding for 4, exhaling for 6, and repeating for 5 minutes a day. Ideal for breaking the mental stress cycle.
Consider natural supplements
Supplements like magnesio, the L-teanina o la rodiola can support cognitive function and reduce mental fatigue. Always consult a healthcare professional before using them, especially if you are taking other medications.
