Abstract
An optimal time spent outdoors is associated with two hours per day in summer and one hour per day in winter for minimizing biological age acceleration.
- Biological age acceleration was measured using two methods: Klemera-Doubal method biological age (KDM-BA) and phenotypic age (PhenoAge).
- KDM-BA acceleration increased with time spent outdoors beyond the optimal duration, while PhenoAge acceleration increased with longer outdoor time regardless of the season.
- PhenoAge acceleration decreased with shorter outdoor time in both summer and winter.
- A negative association between time spent outdoors and KDM-BA acceleration was found only in winter.
