Physical Activity
Wellbeing integrates mental health (mind) and physical health (body) resulting in more holistic approaches to disease prevention and health promotion. Physical wellbeing involves feeling healthy and energised – plays a key role in our overall wellbeing. Regular exercise is one of the best ways to ensure cognitive health according to extensive studies. Being active increases our life span and reduces risk factors for chronic disease, while improving cognitive function, sleep and mental health.
So how much physical activity should we be doing as adults?
- Each week, adults require 150 minutes of moderate-intensity physical activity and 2 sessions per week of muscle strengthening activity of all major muscle groups (legs, back, abdomen, chest, shoulders & arms). The 150 minutes can be split into 30 minutes: 5 times a week. https://www.aihw.gov.au/reports/children-youth/physical-activity#more-info
What are some tips for getting started?

- Setting specific times (and reminder cues) to be physically active: e.g. exercise one hour after breakfast
- Starting slowly to build positive habits and building up to greater challenges
- Joining classes/ activities with others to build motivation
- Reducing the time we sit and increasing the time we move
Diet and Nutrition
Foods not only impact our bodies but also our brains, so dietary changes can be used to improve our mood and mental wellbeing. https://www.health.harvard.edu/topics/nutrition and https://www.eatforhealth.gov.au/
Foods like leafy greens, colorful fruits and vegetables, seafood, as well as nuts, beans and seeds all improve brain health, and foods rich in vitamin B can have core health benefits: eggs, yogurt, legumes, salmon, sunflower seeds, spinach and cabbage
And foods to avoid if you want to keep enhance your memory and focus include:
- Foods made with industrial & processed seed oils: canola oil, cottonseed, sunflower and safflower seed oil contain omega-6 fatty acids which can lead to brain inflammation. Olive, coconut, avocado oil are recommended instead.
- Foods with added or refined sugars: Our brain uses energy in the form of glucose, a type of sugar, but high sugar diet can lead to memory impairments and less plasticity. Savory foods have hidden sugars also, including store-bought pasta sauces, ketchup, and salad dressings, so homemade whole foods are recommended.
- Processed foods: may put you at risk of having shorter DNA: increasing risk of degenerative disease earlier in life. Also, ultra-processed foods like baked goods and sodas are linked to mild depression.
- Foods with artificial sweeteners: increase “bad” gut bacteria which can negatively affect mood, including anxiety. Alternatives that are recommended: Honey, monk fruit extract or coconut sugar.
- Fried foods: battered, crusted or deep-fried foods can be damaging to the brain. Diets high in fried foods are linked to lower scores of memory and cognition. Baked, air-fried, or steamed versions of your favorite foods is recommended.
And the B Vitamins https://www.health.harvard.edu/staying-healthy/the-best-foods-for-vitamins-and-minerals

Sleep
The relationship between sleep and health is well established, with sleep shown to contribute to brain and body recovery as well as mental and physical wellbeing. Sleep is also important for encoding and consolidating information and memories.
A lack of sleep not only reduces your alertness and therefore safety, it is also linked to a range of health issues, including heart disease, diabetes, stroke, obesity and high blood pressure. Sleep deficiency or the inability to attain high quality sleep, may be due to sleep deprivation, or circadian rhythm imbalance: impacting hormone regulation – primarily ghrelin and leptin levels, which can result in excessive hunger and risk of obesity. Insulin, the hormone involved in blood sugar levels, is also impacted by lack of sleep, causing elevated glucose and risk of diabetes type 2. Also, decreased sleep may lead to elevated blood pressure – and which increases the risk of heart disease or stroke. Lack of sleep also alters immune system responses to viruses and infections resulting in chronic low-level inflammation – which factors in many medical conditions.
In regard to cognitive performance: including attention, concentrating, planning and learning new skills, poor sleep also plays a role. Memory consolidation – which occurs during slow-wave sleep cycles and the subsequent rapid eye movement (REM) phase (or dreaming sleep) is likewise influenced by lack of sleep. Sleep is associated also with emotion regulation, coping skills and decision-making.
So how much sleep do we need?
Between 18-64 years, we need 7-9 hours sleep per night.
