Let's Talk About Lifestyle

"When we visit a doctor, we tend to simply expect a prescription and often pay little heed to their advice on health – taking medication seems easier than saying no to a cupcake." Dr Stella George, Chief Medical Officer, International Health talks about lifestyle and the consequences of prolonged unhealthy behaviour.

Of the 41 million deaths due to chronic disease each year, 30% can be attributed by lifestyle risk factors. Eight million to tobacco use, 1,8 million to excess salt/sodium intake, over 1,5 million to alcohol, and nearly a million to insufficient physical activity.

Medication may have taken over as the first-line treatment for many chronic conditions, but better lifestyle can reduce reliance on high levels of pharmacological intervention. Good lifestyle has the power to prevent and even reverse the most prevalent and costly chronic conditions.

Lifestyle over medication

Dietary intervention and physical activity could reduce diabetes-related deaths by more than a million every year. Research shows that lifestyle treatments can reduce or reverse long-standing Type 2 Diabetes within just three months.

Other chronic conditions that can be significantly impacted by lifestyle modification include chronic kidney disease, progression from prodromal to manifest Parkinson’s disease, mental health conditions, autoimmune diseases, and non-alcoholic fatty liver disease (NAFLD).

What is beautiful about lifestyle is it actually augments and strengthens our natural defense systems, thereby reducing the need for artificial or external remedies.

For people with hypertension (high blood pressure) – one of the most important risk factors for cardiovascular diseases – it’s been shown that lifestyle changes can reduce the required number and/or dose of blood pressure medications. One study found that six months after stopping these medications, only 29% of participants who lost weight and restricted their sodium intake required medication again. Conversely, 60% of participants who failed to adopt these changes did need further medication.

Chronic back pain is another interesting area where lifestyle remedies are becoming ever more vital. Our claims data shows chronic lower back pain is an increasingly worrying health threat: back problems linked to musculoskeletal conditions have spiked significantly since the pandemic, up 19% in 2021 compared to pre-COVID levels, 16% in 2022, and 20% in 2023.

Promisingly, the World Health Organization has been advocating for lifestyle changes over pharmacological intervention in this area. Their recent guidance emphasizes the use of acupuncture and cognitive behaviour therapy, as well as for treatment that is holistic, person-centred, integrated, and coordinated.

Stress, the common denominator

Two decades ago, when I was studying medicine, we never talked about stress in terms of lifestyle risk factors. It was always about exercise, diet, sleep, smoking, and alcohol.

But the table below shows just how stress impacts every aspect of our lifestyle.

If we’re stressed, we’re less likely to make healthy choices in diet and more unwilling to exercise or hang out with friends. Stress also increases tobacco, alcohol, and drug use. Even worse, chronic stress can overwhelm our mind and body, causing a number of physical health issues which raise our vulnerability to viral infections and life-threatening conditions, such as hypertension, heart disease, Type 2 diabetes, obesity, and metabolic syndrome.

Physical activity – a silver bullet?

Physical activity changes our energy pattern and affects what we eat, the way we sleep, and sustainable weight management. Best of all – it does not need to involve Olympic-level athleticism or step-counts.

We looked thoroughly at the consequences of insufficient physical inactivity in our previous article, including evidence that higher amounts of sedentary behaviour lead to a gamut of chronic diseases and early death.

Adequate physical activity at the age of 50 and above can be life-changing, even if you have never done any before, because without it your body can quickly become frail. Muscle loss at this age becomes more prominent and undermines your strength, swiftness, stamina, while at the same time you may develop osteoporosis or reduced balance. All these factors mean that without adequate exercise, events such as a fall can more easily result in a fracture, which can take longer to heal and result in further complications.

To slow muscle loss and boost bone health, you need to add protein-rich foods and necessary amounts of vitamins and minerals to your diet, as well as maintaining regular physical activity. This should include 30 minutes of aerobic exercise per day and two hours of exercise to help with strength, balance, and flexibility per week (such as yoga, tai chi, Pilates, and/or isometric weightlifting).

Routine and social network keep us on course

We’re creatures of habit, so developing healthy routines is among the most powerful tools we have to ensure healthier lifestyles.

From childhood onward, establishing good routines set us up for healthier behaviours – that is, dedicating time to eat, sleep, exercise, learn, and listen.

Routine is important for cognitive function and alleviating unnecessary stress. In work, we know reliable processes help us to avoid using brain power on simple tasks, opening the door for more creativity, more time for exercise, and better social connections.

Family, however, is perhaps our most vital social outlet when it comes to forming healthy lifestyle habits. Whether it’s around the dinner table, in the home, out and about, or with the extended family, research shows the family health climate is vital to our perception and cognition of routine. This includes eating all our veggies, going to bed at a certain time, doing our homework, talking about our day, and expressing ourselves.

It’s never too late to cultivate a habit, though. Having an accountable partner, setting specific, measurable, achievable, relevant, and time-bound goals, and following routine are all fundamental lifestyle principles we can live by at any stage in life.

Lifestyle behaviours we can all adopt to live healthier lives

The concept of lifestyle is broad, but it boils down to a few fundamental truths. Eat well, exercise, nurture social connections, and embrace routine. Beyond that, there are a few habits that we know really help to establish holistic physical, mental, and emotional well-being. Some may seem obvious, but they are all essential.

• Maintain a balanced diet

Ensure your diet includes a variety of nutrient-rich foods. Try to eat a balanced diet and eat at regular intervals. Drink enough fluids. Eat lots of fresh fruits and vegetables if possible.

• Prioritize good sleep

Establish a consistent sleep schedule to ensure adequate and restful sleep. Make sure your sleeping area is quiet, dark, relaxing, and a comfortable temperature. Limit your use of electronic devices, and avoid large meals, caffeine, and alcohol immediately before bedtime. Get some exercise; it helps you fall asleep more easily at night.

• Incorporate regular exercise

Engage in physical activities that you enjoy, promoting not only physical fitness but also mental well-being.

• Cultivate social connections

Foster relationships with friends and family, as social connections contribute to emotional support and help reduce stress.

• Practice breathwork

Incorporate intentional breathing exercises into your routine to reduce anxiety, enhance relaxation, and manage stress effectively. Deep and slow breathing reduces anxiety levels and helps to regulate emotions.

• Embrace meditation

Dedicate time to meditation for mental calmness, improved focus, and the development of cognitive skills such as learning and memory. Meditation may also help you manage symptoms of some medical conditions.

• Integrate yoga into your routine

Explore the benefits of yoga, combining physical postures, breath control, and meditation to enhance flexibility, strength, and mental well-being.

• Practice mindfulness in the workplace

Adopt mindfulness practices, such as meditation, in the workplace to enhance your attention span, emotional regulation, and empathy. Allocate time for mental breaks, and learn techniques to manage and regulate emotions – this will help foster a positive and resilient mindset in both your professional and personal life.

A healthy routine makes even major tasks manageable by enabling you to break them into regular, achievable segments. The activities suggested above can help you reach a state of calmness that empowers you to make healthy choices, break your goals into smaller chunks, and improve your mental and physical health through a healthier lifestyle.
