Sharma and Wallace (2020) highlighted the significance of DNA as the distinctive identifier for living organisms. In cells with a nucleus, DNA is a universal presence, consisting of genes. While humans boast around 20,000 genes, only a fraction actively shapes our traits, collectively referred to as the genotype.
Genotype is the genetic blueprint that an individual inherits from their parents, forming the foundation of potential traits. This is a crucial part of understanding the complexity of life's diversity and how it manifests in individuals. Phenotype, on the other hand, is the observable manifestation of genetic instructions as they interact with the environment, giving rise to unique physical characteristics, behaviors, and biochemical processes. The interplay between genotype and phenotype is fascinating, revealing the language of life encoded within our DNA. It is a testament to the intricate balance between nature and nurture that shapes us into who we are.
Epigenetics plays a crucial role in our lives, governing nearly 90% of our experiences by examining how our actions influence our genes. Ayurveda strongly embraces the concept that our actions carry consequences, a phenomenon unfolding within our cells where DNA responds distinctively to our choices. Ayurveda emphasizes four key factors—lifestyle, diet, stress, and environment—that collectively influence our body-mind equilibrium, termed Deha Prakriti. Positive choices uphold this balance, while negative ones disrupt it (referred to as Vikriti), paving the way for illness. Epigenetics serves as the mediator in this intricate system, capable of reversal. Ayurveda actively addresses factors inducing gene changes, imparting a positive influence on both our physical appearance and genetic functionality. Consequently, epigenetics stands out as a pivotal element in Ayurveda's holistic approach to sustaining our health.
How do our daily behaviors impact our health at a cellular level?
Lifestyle
According to Halusková (2010), Epigenetic abnormalities are believed to be a crucial factor in the development, progression, and emergence of various human diseases like cancer, cardiovascular issues, neurodegenerative conditions, and autoimmune disorders. However, there is promising hope in the form of lifestyle interventions that can significantly help in preventing or managing these diseases:
Prostate Cancer – A study examined the impact of a lifestyle intervention program for men diagnosed with prostate cancer. The intervention program incorporated meditation, breathing exercises, aerobic exercise, and a vegetarian diet. The study results revealed significant expression changes in 500 genes, with a notable downregulation of genes that promote disease and tumorigenesis.
Coronary Artery Disease - Individuals diagnosed with coronary artery disease who implemented lifestyle modifications, including stress management, regular aerobic exercise, and adherence to a vegetarian diet, not only experienced a significant alteration in gene expression but also noticed an improvement in their cardiovascular risk factors.
Impact on DNA Methylation - DNA methylation serves as a fundamental biological process, involving the addition of methyl groups to the DNA molecule, particularly at cytosine bases. This intricate mechanism plays a critical role in regulating gene expression without modifying the underlying genetic code, thereby contributing to normal development and the preservation of cellular identity. Disturbances in DNA methylation patterns have been associated with various diseases, including cancer. However, there's promising evidence that lifestyle interventions, such as regular exercise, can exert a positive influence on DNA methylation patterns. Notably, engaging in regular physical exercise has been shown to impact gene regions linked to immune cell metabolism, tumor suppression, and the overall aging process, emphasizing its potential in promoting health at a molecular level.
Diet
Diet can affect our genes through epigenetic mechanisms. These mechanisms include DNA methylation, histone modifications, chromatin remodeling, and miRNA expression. Substances like curcumin can help fight cancer by inhibiting histone deacetylase enzymes, which are linked to various cancers and proteins related to breast cancer. Bioactive compounds found in food, such as polyphenols, genistein, and sulforaphane, can also help prevent and treat cancer. The concept of an "epigenetics diet" suggests using these compounds to counteract epigenetic changes.
Proper digestion is key to the effectiveness of a nutritious diet, and a balanced Agni (digestive fire) plays a pivotal role in ensuring optimal functioning of the digestive system. When Agni is impaired, incomplete digestion can result in the production of Ama - a toxic byproduct that is associated with various disorders.
Research has shown that herbs have an impact on epigenetics by interacting with enzymes that modify histones, leading to the condensation of chromatin. One promising herb is Ashwagandha, which contains Withaferin A. This compound has been found to be effective in treating breast cancer cells by reducing the activity of DNA methyltransferases and histone deacetylase, thereby promoting apoptosis. This is a significant discovery in the field of natural remedies and epigenetics.
Stress
Negative emotions like anger and fear can turn off certain genes by making our DNA tight and short. Positive emotions like gratitude and love, on the other hand, can relax our DNA and allow our genes to work properly. A study on people with high blood pressure found that reducing stress through things like meditation and lifestyle changes helped the telomerase gene work better. This could have benefits for our health. It's important to manage stress to stay healthy. Ayurveda, which focuses on meditation and being aware of our thoughts, can help with this.
Environment
Epigenetic mechanisms can be affected by environmental factors such as toxic substances like diesel exhaust, cigarette smoke, and arsenate. These toxicants have been linked to the silencing of tumor suppressor genes, which can potentially lead to cancer.
Epigenetic changes from factors like nutrition, toxins, and stress can be inherited, impacting future generations and contributing to disease. Air pollution exposure during pregnancy not only affects the mother and embryo but influences the third generation's phenotype. Traumatic stress effects can pass down through generations, even without direct exposure.
How does Ayurveda serve as a guiding light in the journey to suppress diseases and elevate our well-being?
Ayurveda's wisdom offers us valuable insights into building resilience and managing stress. By focusing on increasing Bala and Ojas, we can develop our physical and mental strength, as well as strengthen our immunity. Ojas, the final product of perfect digestion and metabolism, not only maintains and enhances immunity, but also nourishes and sustains our body's tissues. To reduce mental stress and increase our resilience, we can turn to Vedic meditation. This technique takes us beyond the mind into a place of peace and bliss, enabling us to build strength and resilience. Research has demonstrated the remarkable benefits of this age-old practice.
Ayurveda differs from modern medicine by emphasizing a holistic program, incorporating dietary, lifestyle, and psychological interventions to extend an individual's health span. This comprehensive approach aims to restore balance in the body, mind, and emotions simultaneously, offering customized and individualized treatments for overall well-being. The following are some Ayurvedic principles that can be seamlessly incorporated into our daily lives:
Conscious eating
Conscious eating is about recognizing how our eating habits impact our well-being. According to Ayurvedic principles, what, when, where, and how we eat shape our personality and can affect digestion, disease prevention, and aging. Ayurveda suggests following a diet that suits our individual nature and aligning it with the rhythms of nature for better digestion, metabolism, and a longer, healthier life. Eating is seen as a special connection to nature. The philosophy compares the sun, representing fire, to our body's digestion, recommending the main meal at midday when digestion is strongest, and lighter meals in the morning and evening to keep our metabolism balanced.

Abhyanga
Abhyanga it is a regular oil massage involving the use of warm oil infused with constitution-specific herbs. This practice is highly beneficial for maintaining good health and delaying age-related changes. Abhyanga can be incorporated into your daily routine, helping to restore Dosha balance and promote well-being and longevity. It is highly recommended for individuals with central nervous system conditions such as brain injuries, dementia, and mental stress. Several studies have shown that Abhyanga can induce significant changes in brain function and increase cerebral blood flow.
It has been found to reduce stress-related hormones, elevate circulating lymphocytes, and may even enhance the permeability of blood vessels in the central nervous system. In a pilot study, participants experienced a clinically significant reduction in subjective stress, along with lowered heart rate and blood pressure.
Have you ever tried practicing Self-Abhyanga?
First, choose an oil that aligns with your Dosha and make sure it's comfortably warm for application. Then, find a cozy and serene space, and set a mindful intention for relaxation and rejuvenation.
Start by applying small amounts of oil on your scalp using circular motions, then massage your joints with circular motions and use long strokes on your limbs and spine. Don't forget to pay attention to areas of tension, and adjust the pressure as needed. For an even more relaxing experience, sync your strokes with deep breaths. Try to devote at least 5-10 minutes daily to this practice, and remember, consistency is key.
After the massage, enjoy a warm bath or shower, and wear old or dark clothing. Allow the oil to absorb for at least 15 minutes. You'll feel fantastic afterwards! Don't be afraid to tailor this practice to your preferences and make it a cherished part of your routine for physical and mental well-being.
