Exercise is fantastic for your brain’s health – it helps oxygenate the brain and consequently improves memory, concentration and creativity. However, forcing yourself to do exercise you don’t particularly enjoy or dragging yourself to the gym could actually reduce the beneficial results, because when we practice an exercise or sport which we enjoy, something called “brain derived neurotropic factor” (BDNF) is released into the brain. BDNF will help new neurons to grow and form new connections which will in turn sharpen the mind and improve your memory.
However, in reality, the brain was not designed to multi-task. Attempting to do too many things at the same time will prevent the brain from focusing and engaging in deep problem-solving activity.
