Climate change affects more than the weather. Hotter summers, heavier rainfall and changes to the environment can all have an impact on our health and wellbeing.
But some of the things that are good for the climate are good for us too.
A warmer home. Cleaner air. More green spaces. Walking more. Eating well. Wasting less food and medicine. Knowing how to look after ourselves when the weather gets very hot or wet.
These things can help us feel healthier and more comfortable now, while also helping us prepare for the future.
You don't need to change everything. Start with what works for you, your home and your family.
Why take action?
Warmer, healthier homes
Well-insulated homes can help keep us comfortable, reduce energy bills and protect our health during colder weather.
Cleaner air
Reducing pollution from transport, energy and industry can help improve air quality and create healthier places to live, work and spend time outdoors.
More space for nature and wellbeing
Parks, trees and green spaces give us places to exercise, relax and connect with nature. They can also provide shade, improve air quality and help manage heavy rainfall.
Prepare for extreme weather
Preparing our homes, communities and health services for heat, flooding and other extreme weather can help protect people's health and reduce disruption.

Small changes you can make today
There are plenty of everyday actions that can be good for your health and for the climate. Even one or two changes can be a good place to start.
Choose healthier ways to travel
Walk or cycle for shorter journeys when practical, or spend more time enjoying parks, woodlands and other green spaces.
Make your home more energy efficient
Look at ways to improve insulation, reduce draughts and keep your home comfortable throughout the year.
Make the most of food and medicines
Enjoy seasonal and locally produced food where you can, plan meals to reduce food waste and check what medicines you already have before ordering more.
Get involved locally
Join a local gardening or nature project, take part in a litter pick or support efforts to make your neighbourhood greener and healthier.

What is happening across Wales?
It is not all down to individuals.
Changes are also being made across Wales to reduce the environmental impact of health services, make better use of resources and prepare for changing weather.
Hospitals and health organisations are using more renewable energy, improving energy efficiency, creating green spaces and finding ways to reduce waste and reuse equipment.
Here are some examples happening across Wales:
Morriston Hospital uses a solar farm to generate renewable electricity.
Healthcare organisations are reducing waste and looking at ways to reuse equipment.
Some pharmacies are testing better ways to collect and recycle used inhalers.
Green spaces around hospitals and health sites are also being improved for patients, staff, visitors and wildlife.
Healthier people, healthier places
No one person can do everything.
The things we do at home and in our communities sit alongside much bigger changes being made across Wales.
Together, they can help us live healthier lives now and create healthier places for the future.
