Every completed exercise activates a new part of your neural network.
Once you complete all 5 exercises, the light bulb lights up – a symbol of successfully completed training.
Try to keep the bulb lit as long as possible – every additional day helps your mind stay active and in shape.
The calendar tracks your daily training activity:
1 exercise = 20% intensity
5 exercises = 100% intensity
12345
Regular short training supports neuroplasticity of the brain, improves attention, memory and mental flexibility.

Is the autumn time change truly harmless? Circadian shifts impact neural physiology. This neuroscientific article explains the glymphatic system—the brain's nightly waste clearance mechanism—and details how…
The glymphatic system represents the central nervous system's specialized waste removal network. Operating primarily during deep slow-wave (NREM) sleep, interstitial space expands by up to 60%, allowing cerebrospinal fluid to flush out metabolic debris.
Critically, this process clears neurotoxic proteins, including beta-amyloid and tau, whose accumulation is linked to neurodegenerative conditions.
While the autumn time shift offers an apparent extra hour of sleep, it disrupts delicate circadian pacemakers. These internal biological clocks regulate not only hormone secretion but also the architectural distribution of sleep stages.
Even subtle circadian desynchronization reduces NREM sleep efficiency, transiently impairing glymphatic waste clearance capacity.
Gradual Circadian Adjustments: Shift sleep schedules in 15-minute increments ahead of time.
Morning Photic Stimulation: Expose eyes to natural sunlight upon waking to reset central circadian clocks.
Sleep Architecture Optimization: Avoid alcohol and late meals that disrupt slow-wave sleep phases.
