We often hear phrases like “the brain can heal itself” or “rewire your brain.” Social media is filled with conversations around neuroplasticity, emotional resilience, and brain recovery. But how much of this is actually backed by science?
To better understand what “healing the brain” truly means, Swaasth Space spoke with Chennai-based senior neurologist Dr. Shubha Subramanian, who has over 15 years of clinical experience. According to Dr. Subramanian, brain healing is far more complex than most people realise.
Brain healing is not a one-size-fits-all concept
“The term itself is very vague,” she says. “Are we talking about healing from a structural issue in the brain, or are we discussing emotional health?” That distinction, she explains, is crucial. Scientifically, the brain does have the ability to adapt and recover to some extent, even after serious conditions such as head injuries or strokes. However, recovery rarely happens entirely on its own. “In cases like head injuries, strokes, or brain tumors, we must address the underlying issue first,” she explains. “The brain can heal, but we also need to support that healing.” This support may involve medication, surgery, rehabilitation therapies, or symptom management. Without proper intervention, recovery may remain only partial.
The same principle applies to emotional trauma, although the approach differs. Mild emotional stress may improve over time with lifestyle changes and self-care. However, deeper psychological distress often requires additional support systems such as counselling, therapy, or psychiatric care.
Neuroplasticity: The brain’s remarkable ability to adapt
One of the most widely discussed concepts in neuroscience today is neuroplasticity — the brain’s ability to form new neural connections and adapt over time. But Dr. Subramanian cautions against oversimplifying the idea. “Yes, neuroplasticity is the hot topic now,” she says. “But improvement usually happens when we actively support the process.”
In medical rehabilitation, neuroplasticity forms the foundation of therapies such as physiotherapy, speech therapy, and sensory biofeedback. These approaches help the brain create alternative pathways and relearn lost functions. Interestingly, she notes that neuroplasticity is more closely associated with recovery from structural brain problems than with everyday stress or emotional exhaustion. “It is more about motor functions and structural problems in the brain,” she explains.
Can lifestyle habits really improve brain health?
When asked whether habits such as sleep, exercise, meditation, nutrition, and learning new skills can genuinely strengthen the brain, Dr. Subramanian responds simply: “Yes to all of the above.” While there is no instant solution for emotional resilience or cognitive sharpness, years of neurological research show that everyday habits significantly influence brain function.
Good sleep helps the brain consolidate memories and repair itself. Exercise improves blood circulation and supports cognitive health. Meditation and breathing exercises help regulate stress responses, while learning new skills keeps neural pathways active and engaged.
The hidden impact of chronic stress on the brain
Stress is often viewed as an unavoidable part of modern life. However, chronic stress can quietly affect both emotional and neurological well-being over time. “Chronic stress definitely causes issues like disrupted sleep, psychological trauma, and mood swings,” says Dr. Subramanian. The reassuring part, however, is that many stress-related changes are reversible — especially when the stress is environmental rather than linked to severe psychiatric illness. “With lifestyle changes and sometimes medication, improvement can happen over time,” she says.
Simple habits that help the brain age well
According to Dr. Subramanian, consistency matters more than complexity when it comes to protecting brain health as we age.
Her practical recommendations include:
- Strength training and aerobic exercise
- A balanced, nutritious diet
- Yoga and meditation
- Pursuing hobbies that bring genuine joy
- Conscious breathing practices
One technique she particularly recommends to patients is box breathing — a calming breathing exercise that involves inhaling, holding, exhaling, and pausing for equal counts.
In a world increasingly obsessed with quick fixes and viral wellness trends, perhaps the real secret to brain health lies in something far simpler: giving the brain the support, stimulation, and rest it needs to do what it has always been designed to do — adapt, recover, and heal.
