Kentucky summers create great opportunities to get outside and stay active, whether that means biking scenic backroads, walking neighborhood trails, training for an event, or simply spending more time outdoors with family and friends.

But summer heat and humidity can also create serious safety concerns for cyclists, walkers, runners, and anyone participating in outdoor activity.

Across Kentucky, more communities are encouraging active living through improved sidewalks, trails, greenways, bike infrastructure, parks, and community events. As participation increases during the summer months, it becomes even more important to understand how heat impacts the body and how to safely prepare for outdoor activity.

High temperatures combined with Kentucky humidity can quickly lead to dehydration, fatigue, heat exhaustion, or other heat-related illnesses if precautions are not taken seriously.

One of the most important safety habits for both walkers and cyclists is staying hydrated.

People spending extended time outdoors should:

• Drink water before activity begins
• Carry water during walks or rides
• Rehydrate after activity
• Avoid waiting until they feel thirsty
• Consider electrolyte replacement during longer activities

Timing can also make a major difference.

Early morning and evening hours are often safer and more comfortable during peak summer months. Sidewalks, paved trails, and asphalt roads absorb heat throughout the day, which can increase surface temperatures significantly by afternoon.

Clothing matters too.

Light-colored, breathable, moisture-wicking fabrics can help the body stay cooler. Reflective gear and bright colors also improve visibility for both walkers and cyclists, especially during early morning or evening hours.

It is also important to recognize warning signs of heat-related illness, including:

• Dizziness
• Headaches
• Muscle cramps
• Nausea
• Excessive fatigue
• Confusion or disorientation

If symptoms occur, individuals should stop activity immediately, move to shade or air conditioning, and hydrate.

Planning ahead is especially important for:

• Older adults
• Young children
• Individuals with chronic health conditions
• People who are not yet acclimated to summer temperatures

Summer activity should remain enjoyable, not dangerous.

Whether walking downtown, using local trails, biking rural roads, or exploring parks with family, taking simple precautions can help Kentuckians stay safe while continuing to enjoy the many benefits of active living throughout the summer months.

Creating healthier communities means making active lifestyles both accessible and sustainable year-round — including during Kentucky’s hottest days.
