How Facing Cancer Taught our Founder, the Secrets to Aging Well.

Our founder Dr Rahna Rehman, is a physician with advanced qualifications in Integrative and Longevity Medicine. She is also a cancer survivor, who knows firsthand what it feels like to lose control of your health and how to reclaim it back. That journey taught her a profound truth: the strategies that restore health in serious illness—balancing hormones, reducing inflammation, restoring immunity, and nurturing emotional resilience—are the same strategies that optimise vitality as we age.

Aging well is not simply about avoiding disease; it is about creating harmony across all systems of the body. Every cell communicates with every other cell, and optimal health arises not from isolated interventions but from the synergistic effect of addressing nutrition, hormones, immunity, movement, and emotional well-being together.

The Six Pillars of the Biological Conversation

1.Nutrition as Instruction, Not Just Fuel

Food is information. Every bite sends signals to your cells, telling them whether to repair, protect, or inflame. Micronutrients, antioxidants, and phytonutrients do more than nourish—they communicate with your biology, influencing gene expression, immune function, detoxification, and tissue repair.

Aging gracefully requires nutrient-dense foods tailored to your individual needs with conscious awareness. While general dietary principles provide guidance, true therapeutic benefit comes from a personalised approach that considers your metabolism, hormones, gut health, and lifestyle.

2.Movement and Exercise: Vital for Longevity

Exercise is an essential pillar of longevity. Movement does more than maintain fitness—it optimises hormone balance, supports immune function, enhances cardiovascular and brain health, and preserves muscle and bone integrity.

Evidence shows that a combination of strength training, aerobic activity, and mobility work:

• Preserves muscle mass and metabolic health
• Improves insulin sensitivity and blood sugar regulation
• Enhances circulation and lymphatic flow
• Reduces chronic inflammation
• Boosts mood, cognition, and neuropeptide activity

Like nutrition, exercise must be personalised to your body and goals. A tailored program addresses your unique physiology and ensures maximum therapeutic benefit. Exercise works in synergy with nutrition, hormone balance, and emotional well-being, amplifying the body’s capacity to repair, regenerate, and thrive.

3.Hormones: Vital Messengers Connecting Every System

Hormones are chemical messengers that work constantly in a synergistic and interconnected manner to coordinate immunity, metabolism, brain function, and tissue repair. Imbalances disrupt the entire system, accelerating aging and reducing resilience. Hormone imbalances can occur at any stage of life, contributing to the development of disease.

Restoring balance in cortisol, thyroid hormones, sex hormones, and neuropeptides unlocks the body’s ability to respond effectively to all interventions—from nutrition to movement to stress management. This synergistic effect is what creates profound, lasting vitality.

4.Neuropeptides and the Stress-Aging Connection

The body cannot heal in constant fight-or-flight mode.

The human body operates in two primary states:

• Sympathetic (fight-or-flight): alert, stressed, survival-focused
• Parasympathetic (rest-digest-heal): relaxed, regenerating, repairing

Chronic sympathetic dominance—common during puberty, pregnancy, menopause, caregiving, or major life transitions—depletes vital resources in the body, including critical neuropeptides such as serotonin, dopamine, oxytocin, endorphins, and relaxin. These molecules play essential roles in regulating mood, immunity, metabolism, inflammation, and tissue repair.

Prioritising restorative sleep and stress reduction supports the parasympathetic state, enabling the body to consolidate repair processes, restore hormonal balance, and maintain optimal neuropeptide function.

5.Emotional Nourishment & Spiritual awareness: Biological Healing

Loneliness, emotional depletion, and unresolved trauma accelerate biological aging. They disrupt neurotransmitter balance, weaken immune resilience, and impair gut health. The good news is that joy, connection, and a sense of safety are also biologically healing.

True healing—and graceful aging—occurs when mind, body, and spirit are aligned in an environment where the body feels safe enough to repair and restore. This deeper level of healing involves spiritual awakening and connection that extends beyond religion, reminding us that wholeness arises when every part of our being is nourished.

6.Immune Resilience and Emotional Health

Aging is not just about the immune system slowing down—it is about supporting it to adapt and remain balanced. The immune system serves as your internal surveillance and repair mechanism. As we age, it becomes more susceptible to inflammation, infections, and autoimmune activity—a process known as immunosenescence.

Immune decline is not inevitable. It can be supported through gut health, emotional regulation, detoxification pathways, and metabolic balance. Your immune system also responds to hormones and neuropeptides. Neglecting these systems removes vital resources necessary for the immune system to perform effectively.

Advanced Tools for Personalised Longevity

While lifestyle, nutrition, emotional support, movement, and hormone balance form the foundation for healthy aging, some bodies require additional, highly specialised support. At Preciva Health, we have access to a sophisticated toolbox of evidence-informed therapies that go beyond standard options.

These tools are personalised to each individual’s unique biology, helping optimize cellular repair, metabolic balance, immune resilience, and hormonal function. Because no two bodies are the same, the approach is tailored for each person.

By combining foundational lifestyle interventions with advanced, personalised support, we create the most powerful conditions for long-term health, vitality, and graceful aging.
