Does Practise really make Perfect?

When one thinks of the action of practise, it is often synonymous with discipline and order. The fundamental idea of repetitive work is one that is championed by scholars and leaders. Why do we say, ‘practise makes perfect’? Is this a phrase applicable only to one discipline of study, like maths tuition, or is it a more general theory? The scientific impact of practise on the human brain is that the neural pathways work better in unison, by myelination. When we practise a skill over a set period of time, our brain thus becomes conditioned to feel comfortable with the skill – E.g. practising a speech over and over again will make one more confident with the skill of public speaking. It is almost subconscious when we become more attuned to the object of practise.

 

In the life of a student, practise is a certainly an integral pillar of success. Therefore, reserving the period before key exams for revision seems realistic and practical. Private tuition, (such as GCSE levels tuition or 11 plus prep) is a great mode of practise for students to get comfortable with examination conditions. Practise not only allows one to aim for the highest grade, but it also inspires a sense of confidence. If practise encourages personal confidence, it must also have a place in our daily life, whether it be in the extracurricular or academic sphere. The iconic phrase – practise makes perfect – is originated from its Latin form ‘Uses promptos facit’ referenced in the ‘Diary and Autobiography of John Adams’. Clearly, the philosophical and practical message is far from antiquated, and still essential for one’s personal success.

 

However, it must be said that sometimes practise has an innate tendency to feel monotonous. We gain personal satisfaction from seeing immediate results, whereas the ‘art’ of practise can feel like a long-haul endeavour. To achieve the desired results, one must stay diligent over a specific time-frame – this is tough, for boredom can strike, but with perseverance, practise will always achieve results. Will it achieve perfection? The idea of perfection is in itself ambiguous, but what is clear is that practise will make you better at what you are practising. To quote the resounding words of essayist Audre Lorde, “Every day of your lives is practise in becoming the person you want to be”.

Why is food so important for your brain to function?

Introduction

The human brain consumes 20% of the body’s energy. In fact, our brains use more energy than any other organ. Where does this energy come from? Food. Food is our brain’s “fuel” and what constitutes this “fuel” makes a significant difference not only to our cognitive function, but also to our overall health (Selhub, 2016).  A nutritious and balanced diet is pertinent in ensuring that our brain functions at its best. Therefore, by focussing our attention on the foods we eat, and maximising our nutrient intake, we are able support both our short-term and long-term brain function. Ultimately, the “fuel” we ingest impacts how our brains perform physically, emotionally and academically.

 

What foods should I eat?

There’s no magic formula which gives us the ‘ideal’ combination of foods to boost our brain function (Avery, 2020). Instead, one must focus on balance.

High-quality foods that should be incorporated into our diet include: fatty acids, antioxidants, and a range of vitamins and minerals. These all protect our brain from oxidative stress. Oxidative stress is the production of waste products known as ‘free radicals’ in our body. These waste products arise naturally when the body uses oxygen, and can damage our brain cells. Here are some examples of high-quality foods that are beneficial for our mind and bodies and why:

 

FOOD IMPORTANCE
Green vegetables (e.g. spinach, kale, broccoli) High in vitamin K, folate, lutein and beta-carotene.

 

These nutrients have shown to slow cognitive decline (Morris et al. 2016)

Fatty fish (e.g. sardines, salmon, cod) High in omega-3 fatty acids.

 

These fatty acids are essential to the formation of brain tissue and improve cognitive function (Bauer et al. 2014)

Berries Contains large amounts of flavonoids

 

Consuming flavonoids is associated with improved cognition (Miller et al, 2018) and improved memory (Avery, 2020)

Nuts High in omega-3 fatty acids (same reasons as above)
Turmeric Contains the active compound curcumin which has anti-oxidant and anti-inflammatory benefits on the brain.

 

In animals, turmeric has shown to cause improved learning and memory (Khalid et al. 2017)

 

Low-quality foods on the other hand are often highly processed and refined. They tend have a low fibre content and are often digested quickly. Quick digestion means we experience fluctuations in our blood glucose levels which can be harmful to brain health, as well as affect our mood. Refined foods, specifically sugar, have also shown to promote inflammation and oxidative stress.

 

Impact of food on emotional and mental health

So far, we have mainly looked at the benefits of nutrition on cognition and it’s easy to forget the variety of other benefits a healthy and balanced diet provides us with. Of course, what we eat impacts our physical health. Studies have shown that there is also an association between food and our mental health and wellbeing (Mental Health Foundation, 2018). For example, a study by Parletta et al. (2017) showed that a Mediterranean-style diet (high in vegetables, fruits, nuts, beans, fish etc.) was associated with reduced depression amongst participants. This was sustained for 6 months after the intervention. The significance of nutrition in childhood has also been widely studied. Poorer diets which predominantly constitute of poor-quality foods (e.g. with high levels of refined sugars, saturated fats etc.) are associated with experiences of poorer mental health in children and adolescents.

Nevertheless, the association between food and mental health is complex and indeed, nutritional psychiatry is a rapidly evolving field of research. The key thing to take away is that how we feel can impact how we behave, and therefore how we approach demanding tasks such as our academic work.

 

Conclusion

For the majority of us, there are probably quite a few dietary improvements we can think of which would be beneficial to our health. It’s important to recognise that it is never too late to amend our diets, or that of our children. Ultimately, the “You are what you eat” saying is highly relevant in nourishing our brains and small daily changes will amount to large improvements for the long-term!

Why is Exercise important in a busy Exam Period?

Exam time is pressurising. Late nights, last minute preparation, irregular sleeping patterns and eating times are characteristic of exam period. Exam stress can result in anxiety and increased chances of succumbing to illnesses. Getting unwell can undermine your efforts and so maintaining good health and a positive attitude to study is key. Physical activity (PA) is a fantastic adjunct to help relieve stress during exams, whether its KS2 SATs, 11+, GCSEs or A-levels! In addition, PA actually has multiple benefits on brain function, helping you to study efficiently.

Cognition is the process through which an individual acquires knowledge and develops understanding via thought processes, experiences and study. Research on the effects of physical activity (PA) on the cognitive function of children shows improvements in attention; thinking capability; articulation as well as learning and memory.

 

Attention

Kubesch et al. (1) have shown that regularity of PA in children is positively correlated with their ability to focus within the classroom. Interestingly, those children who exercised were able to maintain their attention even through the third hour of lessons, which is usually the time when attentional processes start to deteriorate.

 

Thinking Capability

‘Thinking’ is defined in this context as the cognitive functions involved in abstract thinking, planning, creative thinking and assessing cause and effect. PA helps to develop creativity in children. Research has demonstrated that unorganised PA, such as going to the park, improves thinking capability more than organised sports activities, such as drills and circuits (2). However, it is important to note, that any physical exercise is better than none at all.

 

Articulation and Language

Scudder et al. (3) showed that there was a positive relationship between PA and lexical networks in children, allowing them to comprehend text, spell and detect grammar and syntax errors with greater accuracy.

 

Learning and Memory

Working memory is the type of memory used for short-term to middle-term retention of information and is important in reasoning and decision making. PA has been shown to improve working memory in 8-12-year olds as well as 12-14-year olds (1,4). Learning and cognitive flexibility also increases with PA, enhancing visuospatial memory as well.

 

 

All in all, it is clear that exercise has a plethora of benefits in cognition. In addition to these advantages, dopamine (the ‘feel-good’ hormone) increases in the body during and after exercise, helping you to maintain a positive outlook despite exams! In fact, as a result of the extensive research in PA, the UK Government and the NHS has issued the following guidelines for Physical Activity in children (5):

  1. All children and young people should engage in moderate to vigorous intensity physical activity for at least 60 minutes and up to several hours every day.
  2. Vigorous intensity activities, including those that strengthen muscle and bone, should be incorporated at least three days a week.
  3. All children and young people should minimise the amount of time spent being sedentary (sitting) for extended periods.

 

Incorporating PA is just one way in which you can uphold balance during exam time; getting enough sleep and nutrition are also key to the equilibrium.

Here are a few tips to help you obtain a healthy balance:

 

Good luck!
