Clinical Trial Summary

The goal of this clinical trial is to learn if cold water drinking could promote body composition and further extend healthy lifespan in Chinese older adults. The main questions it aims to answer are: 1. Does cold water drinking lower the body fat percentage? 2. Will cold water drinking positively extend lifespan in a long-term Researchers will compare cold water intervention group to a control group (drinking 37℃ water instead) to see if cold water drinking works to promote health and slow down ageing process. Participants will: 1. Drink 4℃ or 37℃ water 4 times (9a.m., 12p.m., 15p.m., 18p.m.) every day for 6 months. 2. Visit the institute and health checkup department for tests and checkup at baseline, the end of the 3rd month, and the end of 6th month.

Clinical Trial Description

According to pilot study, we found 4℃ water could significantly reduce core body temperature. Thus, we aim to explore whether 4℃ water drinking could promote body composition and further help to extend lifespan. Participants will be randomly divided into intervention (drinking 4℃ water at 9a.m., 12p.m., 15p.m., 18p.m.) and control group (drinking 37℃ water at 9a.m., 12p.m., 15p.m., 18p.m.) for 6-month intervention. Tests will be conducted in Shenzhen Institute of Advanced Technology, while checkup will be tested at Health Checkup Department of Shenzhen University General Hospital. Body composition will be tested by Magnetic Resonance Imaging (MRI), Dual-Energy X-Ray Absorptiometry (DEXA), and TANITA (bioelectrical method). In addition, we will test participants' waist and hip circumferences using 3D scanning. Besides, we will test core body temperature and brown adipose tissue. Apart from above main outcomes, we will also test their physical activity, food intake, metabolic rate, glucose, IL-6, TNF-alpha, HDL, LDL, insulin level. Meanwhile, ageing biomarkers, namely Phenotypic Age, eye fundus image, facial changes, bone density, gut microbiota, GlycanAge, will also be measured. The whole intervention period will last for 6 months. All the tests and checkup will be tested at baseline, the end of the third month and the endpoint of the study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
