A Hobby May Help Keep Your Brain Sharp

Vonetta Dotson, PhD, chief of neuropsychology at Brigham & Women’s Hospital, author of Keep Your Wits About You: The Science of Brain Maintenance as You Age and founder and CEO of CerebroFit Integrated Brain Health, says, “engaging in hobbies is one of the best ways to keep your brain healthy,”  A hobby like painting or drawing, playing an instrument or doing crosswords puzzle can help strengthen our brain’s ability to adapt and build new connections. 

Moreover, as one of the pillars of aging health is to manage stress, hobbies are good at that. People can relax, feel happier, and as studies show, reduce stress hormones such as cortisol, which contributes to anxiety and perhaps even cognitive decline. A pleasurable hobby releases brain chemicals such as dopamine and serotonin that are linked to feelings of happiness and wellbeing.

Retirement is a great time to learn new hobbies as well. Margaret Rice, PhD, professor in the departments of neurosurgery and neuroscience at the NYU Grossman School of Medicine, explains, “Learning something new is stimulating and rewarding. Many studies have shown that novel, positive experiences promote the release of dopamine, which reinforces the actions involved in the positive experience.” She adds, any activity that stimulates a given brain circuit strengthens that circuit and leads to stronger connections, which is a key component underlying learning and memory.

Research involving physical hobbies includes one study that found participants in their 50s and older engaged in vigorous activities improved cognitive function regardless of their cognitive status. At the top of the list for seniors was brisk walking or hiking. Dancing was another fun activity with the added benefit of socializing, which is also good for seniors’ cognitive health. 
Formal volunteering is an activity that allows people to feel a connection and sense of purpose as well as get out and socialize. Experts say it is associated with higher levels of cognitive functioning over time, especially working memory and processing.
