Trends
-
Increase in number, duration and intensity of heat waves and extreme heat conditions because of climate change [1]
-
Increase in heatwaves related deaths [2]
No clear data about trend of people with respiratory conditions- because of COVID 19

Drivers

-
Moving towards community led solutions [4]
-
Rising interest in traditional and indigenous practices [5]
Needs capacity building and research Require extensive research and may not be able to solve the problem alone

Moving towards low carbon emissions sustainable solutions [6]
Broader in scope; not very specific

Rise in respiratory issues due to more early and prolonged pollen seasons [7] [8]
Problem oriented- not solutions oriented


National healthcare focusing on preventative care and resilience [9]
Best balance between feasibility, innovation and impact
Research Gaps
There is a need to provide tried and tested strategies for individuals and families in settings where governments cannot or would not carry out population-level comprehensive programs or implement public health interventions. [10]

Opportunities
Barriers
Pitfalls
Socioeconomic factors should be linked with microclimatic parameters, given individual differences in heat adaptation [11]
Air-conditioning increased dependence upon it, limited passive adaptation and only people living in homes with whole-house air-conditioning had less health problems during heatwaves [12] [13]
Continuance of knowledge-sharing behavior [14]
Enablers
Online knowledge sharing platforms [14]
AI
Unknowns
Understanding the social capital indicators [15]
Real-time microclimate monitoring and mapping are needed to showcase the thermal usability of public spaces and travel paths [16]
Behavioral adaptation measures [16]
Socioeconomic accessibility
UK’s commitment to produce a national cooling action plan [12]
IoT
Wearable fabric that keeps you cool [17]

Future Scenario
In 2035, extreme heat events in London are more frequent than ever, yet the number of hospitalizations among older adults with respiratory conditions has significantly decreased. This improvement is thanks to the Smart Hydration System, launched by the Centre for Climate and Health Security (UKHSA).
The solution integrated a lightweight hydration patch that monitors hydration and electrolyte levels in real time. When levels drop, the refillable bottle dispenses nutrients in the water tailored to the wearer’s needs. Local community hubs buzz with activity, offering bottle refills and workshops on managing heat stress. These hubs have become central to neighborhood life, offering health resources and fostering connections.
Patients feel empowered and supported, benefiting from personalized care while contributing to a resilient community.

PIT Proposal
This initiative addresses the impact of extreme heat on older adults with respiratory conditions through a smart hydration system. It includes a wearable that tracks hydration levels and a refillable water bottle that dispenses nutrient-enhanced drinks tailored to individual needs. The system integrates community hubs where users can refill bottles, learn about managing heat stress, and participate in wellness activities.
Community Hubs
To build trust and awareness in the community by creating accessible hubs
-
Established local low tech cooling and resource hubs across London in heat-prone neighborhoods
-
Provided workshops on managing heat stress, hydration, and nutrition
-
Distributed educational materials and gathered feedback from residents
-
Partnered with local organizations, healthcare providers, and NGOs to ensure reach
2030-31




Wearable Patch
To introduce a personalized solution to monitor and respond to needs
-
Deployed wearable hydration patches to older adults with respiratory conditions via healthcare providers and community hubs
-
Patches monitored hydration, electrolyte levels, and environmental heat
-
Tested and iterated the technology with real-time encrypted data collection to optimize accuracy and user experience
2031-33


Smart Water Bottle
To enhance immunity with tailored hydration solutions and nutritional science
-
Introduced refillable water bottles integrated with nutrient-dispensing technology, linked to the patch
-
Bottles were equipped with reminder systems that alert users to drink water when hydration levels are low or environmental heat increases
-
Community hubs offered refilling stations with access to clean water and nutrient mixes
2033-35
