Ambient Air and Noise Effect on Cardiovascular Health Risk and Lifestyle Intervention to Attenuate It (METSGREEN)

Participants in this group will be instructed to take a brisk 30-minute walk each day in designated urban green spaces (e.g., parks, forested areas). Physical activity will be monitored using Fitbit Alta wristband sensors to track duration, intensity, and steps.

Participants in this group will follow the principles of the Mediterranean diet, including increased consumption of fruits, vegetables, whole grains, legumes, nuts, and olive oil, and reduced intake of red meat and processed foods. They will receive dietary guidance and support for meal planning throughout the 7-day intervention.
