The first arm uses mindful walking through a 2km forest trail in Singapore. All Interventional and Control arms will conduct their walk between 8 am to 11 am for five occasions weekly. At the T1, participants will attend a Zoom orientation session to familiarize themselves with the route. During this session, participants will need to answer the self-report questionnaire and provide the first saliva sample for the baseline measurement. In T2, a pre-intervention and post-intervention saliva sample will be taken before the walk. This will follow by T3 the following week. At T4, participants will attend a 60 mins reflection session and answer the self-report questionnaire. On T5 and T6, the participants will continue with the therapeutic rainforest mindfulness walk. On T7, a pre-intervention and post-intervention saliva sample will be taken. On T8, participants will attend a 60 mins reflection session and answer the self-report questionnaire.

The second arm of the intervention includes walking through a guided forest trail suggested by NParks Board. The collection of samples and answering of the self-report questionnaire will follow the same sequence as the 1st arm of the 3-arm RCT.

The control for this study includes guided casual walking around the campus green trial conducted at the same intervals as per the interventions. The collection of samples and answering of the self-report questionnaire will also follow the same sequence as the 1 arm of the 3-arm RCT.

A two-kilometer trail curated by the National Parks Board, Singapore. The walk will be led by Mindfulness Practitioner who volunteered to be guides for this study.
