Ever wonder what doctors do to keep their own minds sharp and focused? Dr. Saurabh Sethi, a leading gastroenterologist, has opened up about the five powerful practices he incorporates into his daily life to protect and enhance his brain health. Interestingly, one of them is equally beneficial for your gut!
Let’s explore these practical yet scientifically supported habits that contribute to better brain performance and overall wellness.
1. Start the Day with Cold Water Exposure
Cold showers are more than just a wake-up call for Dr. Sethi they’re a daily ritual to stimulate his nervous system and boost alertness.
According to experts, brief cold exposure triggers a “cold shock” response, releasing adrenaline, improving blood circulation, and uplifting mood. It also activates the brainstem, which regulates critical functions like breathing .
2. Reset Stress with Controlled Breathing
Dr. Sethi practices deep breathing techniques to manage stress and emotional reactivity. This helps regulate the amygdala, the brain’s emotional processing hub.
Focused breathing isn’t just relaxing it stimulates the parasympathetic nervous system, reducing cortisol levels and increasing clarity and calm.
Try simple methods like:
- Box breathing (4-4-4-4 count)
- 4-7-8 breathing
- Mindful belly breathing
3. Prioritize Restorative Sleep for Cognitive Repair
Good sleep isn’t optional it’s essential for brain repair, memory consolidation, and emotional balance. Dr. Sethi ensures he gets consistent, high-quality sleep every night.
Dr. Girish Soni, a neurologist from Lilavati Hospital, backs this up: “Poor sleep weakens brain function, regardless of other healthy habits.”
Brain tip: Sleep 7–9 hours, follow a fixed sleep schedule, and eliminate screen time before bed.
4. Feed Your Brain with Nutrient-Dense Foods
The brain needs fuel to function, and Dr. Sethi includes the following in his routine:
- Eggs – rich in choline, supports memory and learning
- Dark chocolate – contains epicatechin, linked to improved brain function
- Green tea – loaded with L-theanine and EGCG, promotes calm focus
These foods are easy to incorporate into daily meals and offer long-term benefits for cognition.
5. Gut Health: The Hidden Hero of Brain Performance
What goes on in your gut affects what happens in your head. Dr. Sethi acknowledges the gut-brain connection, which plays a crucial role in mood, focus, and even memory.
A healthy gut supports the production of neurotransmitters like serotonin, which influence emotional stability.
Gut-friendly habits that boost brain function:
- Include probiotic-rich foods (yogurt, kimchi, fermented items)
- Add fiber-rich fruits and vegetables
- Stay hydrated
- Avoid heavily processed food
Final Thoughts: Simple Habits, Long-Term Impact
Dr. Sethi’s approach to brain health isn’t complicated it’s practical, science-based, and easy to follow. From cold showers to smart nutrition and calming breathwork, these five daily choices can optimize mental performance and digestive wellness.
You don’t need to be a doctor to follow them just a little consistency can go a long way.
