In recent years, there’s been a powerful shift in the way people think about ageing. Rather than simply accepting the decline that often comes with growing older, many are actively exploring ways to live longer and healthier. This isn’t just about lifespan—it’s about healthspan: how long you stay strong, mentally sharp, mobile, and full of vitality.
One of the key movements driving this change is biohacking—a science-driven, self-optimising approach to personal health and longevity.
Sauna Therapy: Heat Up Your Health
One of the simplest yet most powerful longevity tools is the humble sauna. Research, particularly from Finland, shows that using a sauna 4–7 times per week can reduce cardiovascular disease (CVD) risk by up to 50%. Sauna use has also been linked to reduced all-cause mortality and improved brain health.
By promoting detoxification, reducing inflammation, and supporting cardiovascular health, sauna therapy is a proven path to living longer and healthier.
Red Light Therapy: Light That Heals
Red and near-infrared light therapy (typically at wavelengths of 620–680nm and 800–880nm) is used to improve mitochondrial function, stimulate collagen, reduce inflammation, and accelerate tissue repair.
Regular sessions—3–5 times per week—have shown benefits in reducing joint pain, improving skin quality, and boosting energy. As a biohack, red light therapy helps support cellular health, which is foundational for living longer and healthier.
This can also be used for healthy hair growth.
GLP-1 Agonists and Insulin Sensitivity
Another major factor in longevity is metabolic health. Elevated insulin, glucose, and body weight all increase your risk of chronic disease. Enter GLP-1 agonists—a class of medications (like Mounjaro) originally developed for diabetes but now widely used for weight loss.
GLP-1 drugs help reduce appetite, improve insulin sensitivity, and support sustainable fat loss—key elements in any strategy for living longer and healthier. While they’re not for everyone, they are changing the landscape of obesity and metabolic disease management. They may also have anti-inflammatory effects and have positive effects on reducing joint pain from arthritis.
Peptides: The Future of Regenerative Medicine
Peptides are short chains of amino acids that can act like signals to encourage specific healing processes in the body. Biohackers use peptides for purposes ranging from muscle repair and fat loss to immune modulation and cognitive function.
Examples include:
- BPC-157 for soft tissue repair
- Thymosin Alpha-1 for immune support
- GHK-Cu for skin rejuvenation
Used correctly under medical supervision, peptides can be powerful tools for living longer and healthier by promoting regeneration from the inside out.
Hyperbaric Oxygen Therapy (HBOT): Cellular Renewal at Pressure
HBOT involves breathing 100% oxygen in a pressurised chamber, increasing oxygen availability in tissues. Studies suggest that HBOT may extend telomere length and reduce senescent cells—both important markers in longevity science.
It’s also used for brain health, recovery from injury, and even enhanced cognition. When included in a holistic biohacking routine, HBOT supports your journey to living longer and healthier. This can be used in conjunction with blood flow restriction training.
The Big Picture: Build a Healthier Tomorrow Today
Biohacking isn’t about chasing immortality. It’s about using cutting-edge tools and therapies to take control of your health and extend your quality of life well into your later years. From regular sauna sessions and red light therapy, to metabolic control with GLP-1 and peptides, there are now evidence-based interventions available that can help you thrive, not just survive.
Living longer and healthier isn’t just a dream—it’s a strategy. Whether you’re just starting with lifestyle basics or exploring advanced therapies, the key is to be consistent, informed, and guided by real data.
