Brain health is typically linked to traditional factors like a balanced diet, adequate sleep, and regular exercise. However, recent studies suggest that a simple and unexpected habit—cold exposure—might be more effective in enhancing concentration and alertness.
Whether through cold showers or controlled ice baths, research indicates that this practice activates the brain, providing an immediate boost in attention and energy.
What does the science say?
A study published in the journal PLOS One revealed that short sessions of cold therapy can increase levels of alertness and sustained attention, while also improving mood by activating neural networks associated with focus and quick response.
The findings confirmed that the positive effects do not rely on medications or supplements but instead stem from a natural stimulation of brain functions.
The secret behind the effect: concentration hormones
According to the research, exposure to cold leads to an increase in the secretion of norepinephrine, a neurotransmitter crucial for enhancing concentration and attention, as well as boosting energy levels and improving mood.
Another study published in the Journal of Applied Physiology noted that regular cold exposure strengthens the brain's ability to adapt to stress and enhances positive stress responses.
How to safely implement this practice?
To reap the benefits of cold exposure without risks, experts recommend a gradual and thoughtful approach:
Take a cold shower: End a regular shower with 30 to 60 seconds of cold water, 3 to 5 times a week.
Ice baths: Short sessions in water at 5-10 degrees Celsius for 1 to 3 minutes, suitable only for experienced individuals.
Face immersion in cold water: For 20 to 30 seconds to stimulate calm and quick alertness.
Start gradually: Slowly decrease the temperature and pay attention to your body’s signals.
Benefits extending beyond concentration

Benefits extending beyond concentration
Research indicates that regular cold exposure can yield a range of benefits, including:
Improved concentration and sustained attention
Enhanced mood and energy levels
Increased brain resilience to stress
Support for mental performance when combined with adequate sleep, a healthy diet, and exercise
