THE READER LIVES LONGER
A saying goes like an apple a day keeps you away from the doctor, which is also true for a reader. A book a day keeps you away from the doctor and the grave. Most people only focus on the health of the other organs of the body with the exception of the brain. The brain is a vital organ of the human body because it is the centre which controls and coordinates all psychological functions of body systems. Therefore the human brain needs to be healthy as well in order to have a stable mental functionality.
1. Reading strengthens connections in your brain
Reading facilitates new connections between different parts of the brain. A small 2013 study found that reading a novel increased communication between parts of the brain that control language processing. It also created long term changes in the bilateral somatosensory cortex, the part of the brain that processes sensory information.
Sabrina Romanoff, PsyD, a clinical psychologist in New York City, says reading creates neurons in the brain, a process known as neurogenesis. Neurons are cells that send messages and transmit information between different areas in the brain.
"Reading material that requires thought, consideration, and effort to metabolize what's being described leads to the creation of new neurons in your brain," Romanoff says. "These neurons also increase new neuronal connections, both with each other and older networks, which accelerates processing speed."
2. Reading prevents age-related cognitive decline
Cognition includes the ability to learn, remember, and make judgments. Attention and memory are the two aspects of cognitive functioning most likely to be affected by age. Scientists believe reading can reduce age-related cognitive decline and protect cognitive function.
A large 14-year study published in 2020 found those who read one or more times a week were less likely to have cognitive decline at 6-year and 14-year intervals. After 14-years, older people who read more often had a reduced risk of cognitive decline compared to those who read less often.
Reading is even associated with a lower risk of dementia. A very large 2018 study in China tracked people aged 65 and older over the course of five years and found late-life participation in intellectual activities like reading was associated with a lower risk of dementia several years later.
3. Reading reduces stress levels
Research has found reading for just 30 minutes can reduce the physical and emotional signs of stress.
A small 2009 study of full-time undergraduate students compared the effects of yoga, humorous videos, and reading on stress levels. It found students who read news articles for 30 minutes experienced a decrease in physical markers of stress, like heart rate and blood pressure, compared to before they began the activity. They also had lower scores on stress surveys.
The study concluded "neutral" reading material, or material that doesn't elicit a strong emotional feeling, is relaxing, and decreases arousal of the sympathetic nervous system which directs the body's response to stressful situations and danger. However, reading the news may not be relaxing for everyone. Instead, you can opt for novels, short stories, or other reading materials.
4. Reading may even help you live longer
Not only is reading beneficial for brain health, but it is also linked to a longer life. A large 12-year study published in 2017 found reading books is associated with a 20% reduction in risk of mortality compared to those who didn't read books.
Reading may not cause you to live longer on its own, but it might be associated with an overall healthy lifestyle and a lower risk of early death.
5. Reading improves memory and concentration
While the brain isn't a muscle, it still benefits from exercise. Similar to how lifting weights makes our bodies stronger, reading is a cognitively demanding process that can strengthen memory and concentration.
When humans read, we create a "mental map" of written text. This mental map helps us process words we are reading and aids in knowledge recall and memory. Romanoff says a regular reading routine helps the brain "practice" mental processes that contribute to memory functioning.
"Our brains also mentally process written words as if we were writing them," Romanoff says. "These processes require mental effort and concentration. With continued reinforcement, there is a greater capacity for memory functioning."
A 2013 study of elderly men and women found people who participated in mentally challenging activities like reading and writing had a slower rate of memory decline earlier and later in life compared to those who did not engage in such activities.
*How to make reading a habit?*
Uma Naidoo, MD, a nutritional psychiatrist and the director of nutritional & lifestyle psychiatry at Massachusetts General Hospital, says that the easiest way to start reading more is to schedule it into your daily life.
"Like with any activity that promotes our better brain health — such as how we eat, sleep, or exercise – we need to create space for these," Naidoo says. "Setting aside a half-hour or an hour, for example, before bed or during an afternoon break could be a good idea to make sure you are reading."
Other tips to start reading more include:
• Keeping a book with you when traveling or commuting to work
• Reading the news every morning
• Reading books on topics you want to learn more about or are interested in
• Reading a book before watching the movie version
• Getting a library card
• Be patient — reading, like any skill, takes time to develop
