Summary

This study looks at whether the time of year—summer vs. winter—changes a person's biological age, which is a measure of how fast their body is aging. Researchers will track 60 healthy adults over 40 for 12 months, using blood or saliva tests to calculate aging clocks. The goal is to understand how seasonal factors like vitamin D and lifestyle affect aging, which could improve future anti-aging studies.
