Dr. Joseph Mercola - Take Control of Your Health Strong Calves Are Linked to Better Brain Health
Oct 18, 2025
Discover how strong calf muscles act like a second heart, enhancing circulation and boosting brain health. Research links larger calves to better balance, reduced dementia risk, and improved cognition as you age. Simple exercises like calf raises, lunges, and squats can build muscle and stability. Tracking calf size offers a measurable way to protect both body and mind, while the soleus muscle plays a crucial role in continuous venous pumping. Join the one-week calf challenge to re-measure your progress and note improvements in both strength and stability!

Calves Work As A Second Heart
- Strong calves act like a second heart by pumping blood back to the chest and brain when they contract.
- This mechanical action supports oxygen delivery and reduces stagnation, aiding cognition and energy.
Calf Size Correlates With Cognition
- Smaller calf circumference (under ~31 cm) tracked with weaker thinking in a study of 12,000 older adults.
- Calf size effects leveled off above 31 cm and were stronger in women, especially those over 85 or less active.
Calf Strength Lowers Fall And Dementia Risk
- Strong calves stabilize ankles, reduce knee and hip strain, and lower the likelihood of trips or slips.
- Fewer falls link to reduced dementia risk, making calf training an investment in independence and mental resilience.
