What is good for your brain is good for you and for your happiness.Although the brain is not a muscle, exercise can stimulate its growth and regeneration in a similar way to a workout providing greater muscularity. Research in the field of neuroplasticity has shown that many aspects of the brain can be altered (or are "plastic") even into adulthood. By building new brain tissue, it is possible to overcome cognitive impairment and – at the most fundamental level – to feel a higher degree of engagement in the world and of overall happiness.
Recent studies have shown that physical exercise can improve brain functions. In one research paper published by Elsevier Inc., it was discovered that a key player in intracellular proteolysis – Cathepsin B – was found to be secreted in the body in greater quantities in runners than in people who had taken no exercise. Put simply; this means that the memory function of the human brain is improved by simply taking exercise.
Psychologists like Dr Matthew Edlund, who has published books like “Designed to Last”, have pointed out that similar restorative effects on the brain which have been derived from physical activity have been found in other species, too. So, should we work our brains like a muscle if we want to feel higher happiness in some cognitive training programme? Well, yes. But that is not the full story. For anyone wishing to overcome cognitive impairment, then other things, such as social activities, are just as important as the exercise itself.
In all, there are five different categories to consider if you want to be happier in yourself and to avoid the sort of cognitive impairment that is all too often prevalent in older age. Let's examine what we can all do to keep our brains in good condition so that we feel better about ourselves right now and in the future.
In fact, as far as your brain function is concerned it matters little what you learn, so long as you engage in learning itself.According to no less an authority than the Alzheimer's Association, a body which knows a thing or two about cognitive impairment, there are plenty of tasks we can give our brains which will guard against the condition in the future. According to them, formal education is known to reduce the risk of cognitive decline and dementia. Crucially, this is the case no matter when it is taken in life.
If you think that attending classes is for children or for people who need to upskill during the early part of their career, then there is little doubt that you are right. That it is also for middle-aged people and recently retired folk is equally as valid, however. Regarding happiness and fighting off cognitive impairment, there can be few better tactics than learning about something you are already interested in in a formal way.
Cognitive training might take the form of learning a foreign language ahead of an overseas holiday or studying a little art history to make that next trip to the gallery a more informed experience. In fact, as far as your brain function is concerned it matters little what you learn, so long as you engage in learning itself. However, if a classroom environment is not for you, then why not consider other methods of engaging your brain with new skills. Meditation, Bridge classes or logic puzzles will train your brain to work in new ways, especially games which need you to think strategically. Such activities have been widely researched in study programmes – many of them indicating clear beneficial outcomes for the brain.
Selfless though it might seem, joining a local community volunteer group might be the best thing you ever do for yourself.Like cognitive training, being social creates better brain functions because it forces the brain to work in specific ways. If you are locked away from the world to an extent, then not being sociable can become a habit. It may lead to the brain's neural pathways shifting over time to the extent that you never feel like engaging in social activities again. To prevent this, take affirmative steps to ensure you are not cut off from your neighbours, family and friends.
Taking a role in your local community does not merely derive benefits for those around you – it will help your brain to remain active in a meaningful way which will help to prevent neural problems in future. Selfless though it might seem, joining a local community volunteer group might be the best thing you ever do for yourself. Of course, just being around people is often enough to induce the brain's chemicals that make us feel better about ourselves. Chatting, interacting, learning and teaching are all things that will keep your brain active, too.
Throwing yourself into a new group is an excellent way of proceeding but – let's be honest – this is not for everyone. Some of us are just a little shy, and this great leap can seem too much – to begin with, anyway. If you want to take care of your brain, then take smaller steps, to start with. Why not pick up the phone to a friend you haven't spoken to in a while and just ask them how they are? It is a great way to get the ball rolling and strong social connections are a main ingredient for a good life.
According to a study by Martha Clare Morris, et al, of the Department of Internal Medicine at the Rush University Medical Centre in Chicago, a hybrid of a Mediterranean and a so-called stop hypertension diet will slow down cognitive decline. Morris' work dealt with 923 participants who were aged from 58 to 98 years and engaged in what is often referred to as a DASH diet. Essentially, such a diet is low in trans fats, rich in potassium and calcium and requires a smaller salt intake. By limiting dairy and meat in favour of vegetables, whole grains and fruit, you can eat your way to a healthier brain.
Long considered to be good for the brain, the consumption of fish is also useful. According to a 2014 paper in the American Journal of Preventive Medicine, baked or broiled fish eaten on a weekly basis will mean you have more grey matter – on average – compared with people who don't have this level of consumption. Bear in mind that fried fish did not make up any part of the research, however. Also, the fatty acids, like omega-3, found in fish seem to work better when consumed as food rather than as a dietary supplement, as reported in Time magazine. Perhaps this suggests fish have some unknown improving effect on brains?
It is important to note that exercise is not just about maintaining good cognitive abilities. It can help the brain recover where it might have been going into decline. According to research by Elise Wogensen, et al., of the Department of Cognitive Neuroscience at the University of Copenhagen in Denmark, the exercise in a large number of cases can promote cognitive recovery after an injury that the brain has sustained. Although there are some factors which are still to be established as to how this works, Wogensen's work indicates strongly that physical activity and restoring brain functions are linked and that the rehabilitation of 'lost' brain functions is possible.
