A diet high in refined sugars can negatively impact brain function by causing inflammation, oxidative stress, and insulin resistance

Physical activity increases blood flow to the brain, promoting the growth of new neurons and reducing the risk of cognitive decline. A sedentary lifestyle, on the other hand, is linked to memory problems and decreased mental clarity

Prolonged stress leads to excessive cortisol production, which can damage brain cells, shrink the hippocampus (the brain’s memory center), and increase the risk of mental disorders like anxiety and depression

Human interaction is crucial for maintaining cognitive abilities. Loneliness and lack of social engagement have been associated with increased risks of dementia and depression

While multitasking may seem efficient, it actually reduces productivity and negatively impacts memory and concentration. Focusing on one task at a time enhances cognitive performance and efficiency

Breakfast provides essential nutrients and energy needed for brain function. Skipping breakfast can lead to low blood sugar levels, reducing focus, concentration, and mental alertness
