Four pillars of health according to Greg Wells


Chronic sleep deprivation has become a global epidemic, affecting nearly 20% of the population, with factors like busy work schedules and household responsibilities contributing to the problem. The consequences of inadequate sleep are profound, leading to increased risks of heart attacks, strokes, anxiety, depression, and even premature death. Sleep is a dynamic process comprising non-rapid eye movement (NREM) and rapid eye movement (REM) stages, each playing a crucial role in body and brain restoration. NREM sleep allows for physical recovery, including muscle repair and tissue growth, while REM sleep supports cognitive functions and memory consolidation.

Circadian rhythms, regulated by the suprachiasmatic nuclei (SCN) in the brain, control our sleep-wake cycle, body temperature, and hormone release. Aligning our activities with these rhythms can optimize health and performance. Sleep’s significance is underscored by its role in strengthening the immune system, enhancing memory and learning, and reducing stress levels. Inadequate sleep is linked to various health issues, including cancer, inflammation, cardiovascular diseases, obesity, and mental health disorders. Research shows that poor sleep can have a detrimental impact on overall well-being, making it a cornerstone of a healthy, high-performance life.

2Move more

The author highlights the transformative power of exercise on various aspects of human health. Wells calls exercise a ‘miracle drug’ that can prevent and treat numerous chronic illnesses, such as cancer, cardiovascular disease, diabetes, and more. Regular physical activity is presented as a key solution to combat the global inactivity epidemic, which is linked to the rise of non-communicable diseases. The book also touches upon exercise’s role in improving mental health, particularly in managing conditions like depression and anxiety. Additionally, it emphasises the importance of moderation and consistency in exercise routines and how even small steps toward physical activity can lead to significant health improvements.

3Eat smarter

Greg Wells highlights healthy nutrition as the third pillar of health. He cites studies that have shown that nutrition and exercise can be used to treat and prevent various diseases, challenging the traditional approach to medicine.

Nutrition plays a crucial role in preventing and treating cancer, with certain foods, compounds, and nutrients offering protection while others may increase cancer risk. The Mediterranean diet, rich in protective foods like fruits, vegetables, and omega-3 fatty acids, is recommended. Nutrition also influences inflammation in the body, which is linked to various chronic diseases, including Alzheimer’s. An anti-inflammatory diet, high in antioxidants and omega-3s, can help reduce inflammation and cognitive decline. Furthermore, nutrition impacts cardiovascular health, and consuming antioxidant-rich foods can improve cardiovascular function. Eating for mental health is gaining importance, as research indicates that foods like green tea, dark chocolate, omega-3 fatty acids, and B vitamins can alleviate symptoms of depression and anxiety. Finally, nutrition can also influence sleep, with high-protein meals and foods rich in tryptophan and healthy carbohydrates promoting better sleep quality.

4Take care of your mental well-being

The author discusses various strategies to improve mental health and overall well-being. Wells emphasises the importance of practising daily gratitude, spending time on building deep relationships, investing in experiences over possessions, volunteering to help others, and engaging deeply with life by reducing distractions. These practices are supported by research and can lead to increased happiness, decreased stress, and improved performance in various aspects of life.

Additionally, the author explores the intricate connections between mental and physical health, addressing the impact of chronic stress on the immune system, the bidirectional link between mental health and inflammation, and the relationship between mental health and obesity. Wells explains that by engaging in mindful practices, one can not only improve psychological well-being but also prevent chronic conditions.

Best quotes from The Ripple Effect

“We mistakenly think that working ‘harder’ is the key to success.”
“Early findings show that practising cyclic meditation improves subsequent sleep. Cyclic meditation involves alternating yoga postures and supine resting. Those participants who practised this technique experienced more slow-wave sleep and fewer awakenings than on nights when they did not practise. They also reported being more refreshed and feeling better, in the morning.”
“Research shows that melatonin can be a helpful tool in overcoming jet lag. Melatonin acts on the body’s circadian rhythms by means of the SCN (the culprits of desynchronization that live in the hypothalamus) and promotes sleep, an elusive concept for frequent travellers. Taking 0.5 to 5 mg of melatonin 2 to 3 hours before local bedtime has been shown to help resynchronize circadian oscillators while improving nocturnal sleep and alertness during the day.”
