Climate change poses risks to human health. Already in the United States, we are seeing rising
temperatures, increased frequency and intensity of some types of extreme weather, sea level rise, and
other changes in weather and climate patterns. We are all vulnerable to the health impacts associated
with climate change. However, these climate and health risks vary across the country.
Most of Indiana has warmed about 1F in the last century and floods are becoming more frequent.
These and other climate impacts mean increasing risks to health. Examples of risks and actions for
Indiana residents include:
-	Heat waves have become more common in the Midwest over the last 60 years. Higher
temperatures will increase heat-related illnesses, hospital visits, and deaths. Learn how you can
take action to protect against heat waves, such as:
o Respond: Watch for signs of dehydration and overheating, especially in children.
o Respond: Check on elderly neighbors or anyone else who may need assistance.
-	Longer warm seasons mean that ticks will emerge earlier in the season. Already common in
the Midwest, Lyme disease infections will increase. Learn how you can take action to protect
against ticks, such as:
o Respond: Check for and remove ticks promptly after coming indoors. Remember that
pets may bring ticks into the house.
o Respond: Wear protective clothing (such as high boots and long sleeves and pants), and
consider using insect repellent.
-	More intense rain can overwhelm combined sewer systems (where storm water and sewage
share the same pipes). Overflows into Lake Michigan are expected to increase 120% over the
next 80 years. This could pollute recreational and drinking water sources. Learn how you can
take action to ensure drinking water safety, such as:
o Prepare: Have an emergency water supply ready for your family (1 gallon per
person/pet per day).
o Respond: Check the news for tap water safety notices, such as boiling water before use.

provide users with illustrative impacts and resources for further information. Examples were
selected based on relevance to the state or region and representation of a diversity of health
threats. Selection does not imply ranking of severity of impacts nor prioritization of actions. The
