Heat can cause serious illness. Heat illnesses can be deadly. On very hot days, sometimes your body temperature control systems can't keep up and your body temperature can get dangerously high. This makes you at greater risk for serious heat illnesses, including heat exhaustion and heat stroke. Heat stroke is a life-threatening emergency. Dial 9-1-1 or get immediate medical help if you are concerned about your health or someone else's health when it's hot outside.
Heat illnesses are a real danger, even here in our northern climate. Vermonters go to the emergency room for heat illnesses just as often as people in Maryland. Being young does not protect you from heat illness. In fact, Vermonters between the ages of 15 and 34 have a greater risk of going to the emergency room for a heat-related reason compared to adults aged 35 to 65.
In general, risk for heat illnesses is greater for people with:
- More exposure to hot conditions – especially outdoor workers and hobbyists, urban residents and homeless persons
- More sensitivity to heat exposure – anyone not accustomed to hot weather, older adults and young children, people overweight or with a chronic medical condition (e.g. cardiovascular disease, Alzheimer’s disease and diabetes), and people using recreational drugs, alcohol or some prescription medications
- Limited resources – especially people who live alone, have limited transportation options, have no air conditioning or can’t afford to run their air conditioner
People who feel unwell or faint in hot weather are also vulnerable to serious or deadly falls.
People with chronic conditions may not show typical signs of heat illness, but rather worsened symptoms of their condition. If you or someone you know has a potentially dangerous chronic condition and begins to feel sick during a hot day, pay very close attention. Get immediate medical help if you have concerns about a person's condition.
Vermonters are at greater risk for serious heat-related illnesses, and even death, when the statewide average temperature reaches 87°F or hotter. Since 2000, Vermont has had an average of seven hot days per year when the temperature reached 87°F or hotter.
Climate models from the Vermont State Climate Office predict 15 to 20 hot days per year by mid-century, and 20 to 34 hot days per year by the end of the century. As the climate warms and there are more hot days, more heat illnesses and deaths will occur. Some of these impacts can be avoided by taking actions to prepare and adapt.
NEVER leave children, people with disabilities or pets inside a parked vehicle when it's hot. The sun can turn a vehicle into an oven within minutes, even if it doesn’t feel hot outside.
- Stay in the shade, in air-conditioning if you can, or in cool places such as basements.
- Wear lightweight, light-colored, loose-fitting clothing.
- Take cool showers.
- Use fans, but don't rely on them as the only way to stay cool.
- Go to public buildings that are air-conditioned.
- Sleep without sheets.
- Avoid hot drinks and meals.
- Drink more water than usual, especially if you're exercising or active outdoors.
- Be proactive, don’t wait until you are thirsty to drink water.
- Don't drink alcoholic or caffeineated beverages.
- Follow local weather and news reports.
- Sign up for weather alerts at VT-Alert.
- Try out the National Weather Service Experimental Enhanced Weather Outlook Map.
- Check Health Department social media (Twitter and Facebook) and Vermont Emergency Management social media (Twitter and Facebook).
LISTEN TO YOUR BODY
- Take it easy when it's hot.
- Reduce outdoor work and exercise and limit it to the cooler parts of the day.
- Ask for help if you feel sick.
- Stop what you are doing if you feel faint or weak.
- Be more cautious if you have a chronic health condition.
DON’T BE A STRANGER
- Check on your loved ones and neighbors, especially if they are elderly or have chronic health conditions.
- Make sure they are drinking enough water and are staying cool.
- Remind them to take heat seriously
COOL your home
- Draw light-colored shades to keep out the sun—dark-colored shades can be less effective.
- Close windows during the day when it is hotter outside than inside.
- Open windows at night when it's cooler outside than inside.
- Use fans to blow in cooler outside air or vent out warmer inside air.
- Limit use of the stove, oven and other heat-generating appliances.
- Modify buildings and ventilation systems to increase cool air flow while venting out hot air.
- Seal air leaks and properly insulate to help keep buildings cool in summer and retain heat in winter.
- Plant trees, shrubs and vines around buildings to maximize summer shade and cooling breezes.
- Replace incandescent light bulbs with LED bulbs that stay much cooler and save energy.
- Put in air conditioners, heat pumps or similar cooling devices.
- Use light-colored materials to reflect heat when you replace your roof.
- Choose energy-efficient options when replacing siding, doors and windows.
- Learn more about ways to keep your home cool at Efficiency Vermont.
- Create a community response plan that identifies protective actions to take on hot days.
- Open cooling centers or other air-conditioned, publicly accessible places for those without air conditioning and for the homeless.
- Mobilize local care networks to check on people at at high risk for heat illness.
- Limit or cancel outdoor job, school or extracurricular activities, including athletic practices, games and other outdoor events.
- Plant trees and shrubs, and reduce paved surfaces to keep urbanized areas cooler.
- Promote energy-efficient building design, including use of cool roofs and pavements.
