Sleep is essential in order for our brains to function well as we age. A 2014 study found that those with poor sleep tend to have more memory and problem solving concerns. A local study also found that the less we sleep the faster our brains age.
Exercise is another key ingredient for healthy aging. The authors of a 2014 study report that those who didn’t exercise regularly were more likely to have problems with their memory. Moreover, older adults with have better lung and heart health, which is enhanced through regular physical activity, also tend to have better memory and problem solving abilities, according to another 2014 study.
Being socially active is another cornerstone for optimal aging. And these days social connections includes those through social media: According to a 2014 study, training older adults to use social media helped to improve their mental well-being. It’s clearly never too late to learn!
Our outlook on life can also contribute to our ability to age well. A 2014 study finds that those who are cynical — that is, those who tend to believe that others are “mainly motivated by selfish concerns” — are more likely to have dementia. Researchers observed that depression rates were lower among older adults who used the internet, according to a 2014 study.
It’s of course also important to eat right. A 2014 study finds that one gramme (1g) of tumeric a day improves the memory of those in the early stages of diabetes (and who therefore have a higher risk of dementia). Other research shows that eating baked or broiled fish once a week is associated with better brain functioning among older adults. According to this 2014 study, it doesn’t matter whether the fish that you’re eating has a lot of omega-3 fatty acids or not. That means that including ikan kurau could be just as beneficial for your brain health as salmon is. Fish curry, anyone?
Pursuing mentally challenging activities also plays an important role in determining how we age. A 2014 study shows that having a mentally challenging job is associated with better cognitive functioning later in life, while another 2014 study finds that those who engage in intellectual activities are less likely to experience cognitive decline later in life.
But it’s not actually about playing more majong or playing video games. Rather, it’s important for us to learn new skills. As they say, either you use it or you lose it. And recent research does show that learning a demanding skill pays dividends.
So here are 3 simple ways to challenge yourself.
1. Shop at a different supermarket
Instead of going to your usual supermarket, challenge your brain by going to a supermarket that’s not familiar to you. By going to the a different NTUC, Giant, or Sheng Siong, you’ll be able to find the brands you want, but your brain will have to work harder to locate them. Plus it could save you time, especially if you did your grocery shopping together with your other errands at the same location.
2. Explore a new route
Instead of doing your errands by the usual route that you know, try a different route. It could be using a different MRT line or bus route. It could be finding a different way to walk from the bus stop or MRT station to your office or home. Challenge your brain to add more information to the mental map that you already have for that neighbourhood or area.
3. Learn a new routine
You may already have a hobby that involves learning a pattern or routine. If you already read music, learning to play a genre that’s new to you (e.g., jazz) or learning a new instrument (e.g., the ukelele) will definitely help you make new neural connections.
If your hobby involves movement, try learning a new form. For dancers, this could mean trying something new like ballet for adults, tango, or tap. For those who practise tai chi, it could mean learning another style or form. Instead of cycling, learn to roller-blade or ice-skate. Or try a cycling trail in a nature reserve instead of using the park connectors.
If you’re already very practised at solving sudoku and optimizing your Freecell score, you may be surprised to find out that doing more of the same (even if you’re attempting the really difficult stuff) isn’t likely to be helping you delay dementia.
Because if you’re not outside your comfort zone, your brain’s probably not busy making new neural connections and you’re not building up your cognitive reserve.
