Health Update: Jess Sepel’s 6 Big Wellness Predictions For 2026 – What Experts Say

Longevity is shifting from an abstract concept to everyday practice. In particular, I expect growing interest in accessible longevity rituals like sauna use, which is increasingly associated with cardiovascular health, reduced inflammation and improved mental wellbeing²³. 

Alongside this, nutrients traditionally associated with performance and anti-ageing are entering mainstream wellness conversations. Creatine, for example, is emerging as an important longevity-supporting nutrient for women. Women naturally store less creatine than men, and research now highlights its role in muscle preservation, bone health, cognitive support and metabolic function across the lifespan⁴. 

We’ll also see increasing curiosity around cellular health compounds such as NMN, as interest grows in supporting mitochondrial function and healthy ageing at the cellular level⁵. Longevity in 2026 is less about optimisation at all costs, and more about preserving strength, confidence and vitality over time.
