Guard Against Heat-Related Illness and Lightning Strikes; Protect Your Pets
The combination of hot temperatures and high humidity may cause heat illnesses to occur. In addition to avoiding being outside for long periods of time, Loudoun County officials remind residents to take other precautions to prevent heat-related illnesses and to stay safe from severe thunderstorms.
- Hydrate: Drink plenty of water.
- If you have to go outside, wear lightweight, light-colored clothing and avoid strenuous activities.
- Do not leave children or pets in cars.
- Monitor your animals frequently to ensure that they are not suffering. The Loudoun County Department of Animal Services offers useful information on protecting your pets from the heat.
- Check on your neighbors: Anyone can suffer from heat-related illness, but people aged 65 and older and very young children are more susceptible to the effects of high heat and humidity.
- When thunder roars, go indoors: If you hear thunder, you are likely within striking distance of the storm. If you see threatening clouds approach, see lightning or hear thunder, seek safe shelter immediately.
