The brain is an extremely complex organ that uses a large percentage of the body’s oxygen and nutrients. It relies heavily on an efficient circulatory network.

Health

When it does work, the heart provides a steady and efficient delivery of these essential nutrients.

Health

Such a steady stream of oxygenated blood nourishes the brain’s intricate network of neurons, enabling vigorous cognitive processing, memory, and general mentation.

Health

However, cardiovascular diseases, namely hypertension, atherosclerosis, and heart failure, can disrupt this delicate equilibrium. 

Health

These conditions can lead to diminished blood flow to the brain, which in turn may damage brain tissue and affect cognitive function.

Health

Lifestyle changes and urbanisation have led to a rise in cardiovascular diseases in India. Eating well, staying active can go a long way in keeping the heart healthy.
