Houston Walks: No Shade Inflating Summer Strokes?
By Franklin Everett ShawThe air in Houston in July isn’t just hot; it’s a thick, suffocating blanket. You step outside, and it feels like you’re immediately wrapped in a damp towel fresh from the dryer. That seemingly harmless walk to the Heights HEB can quickly turn dangerous if you’re not prepared. Heatstroke is a real threat here, and knowing how to avoid it could save your life, or someone else’s.
Houston’s heat and humidity create a perfect storm for heatstroke. The humidity prevents sweat from evaporating efficiently, which is your body’s natural cooling mechanism. This means your core temperature can rise rapidly, leading to heatstroke.
So, how do you enjoy the outdoors without becoming a statistic? It’s all about smart planning and understanding your body.
First, let’s talk about shaded routes. Houston isn’t exactly known for its dense forests, but there are pockets of green that offer respite from the sun.
Memorial Park: This is a classic for a reason. The park boasts miles of trails, many of which are shaded by mature trees. Focus on the trails closer to the Bayou, as they tend to have more tree cover. The Seymour Lieberman Exer-Trail (the 3-mile loop) is partially shaded, but be aware that some sections are exposed.
Buffalo Bayou Park: While not entirely shaded, Buffalo Bayou Park offers some shaded areas, especially along the bayou itself. The Waugh Drive Bridge Bat Colony viewing platform is a good landmark to aim for, as the area around it has decent tree cover.
Terry Hershey Park: Located along Buffalo Bayou further west, this park offers a long, paved trail with sections of shade. The trail follows the bayou, providing a slightly cooler microclimate.
Hermann Park: This park offers a mix of sun and shade. The Japanese Garden provides a tranquil, shaded escape. The McGovern Centennial Gardens also has some shaded areas, but be mindful of the open spaces.
The Heights Hike and Bike Trail: This trail offers some shade, particularly in the early morning or late afternoon. However, be aware that sections along the power lines are fully exposed.
Beyond specific locations, consider the time of day. Walking between 10 AM and 4 PM is generally a bad idea in Houston during the summer. The sun is at its strongest, and the heat is most intense. Aim for early morning walks (before 8 AM) or late evening walks (after 7 PM) when the temperature is lower and the sun’s rays are less direct.
Hydration is absolutely critical. Don’t just drink water when you’re thirsty; proactively hydrate throughout the day. Carry a water bottle with you and sip on it constantly.
But here’s the thing: water alone might not be enough. When you sweat, you lose electrolytes, which are essential for proper bodily function. Low electrolytes can exacerbate the effects of heat and increase your risk of heatstroke.
So, what should you drink? Sports drinks like Gatorade or Powerade can help replenish electrolytes, but they can also be high in sugar. A better option might be electrolyte tablets or powders that you can add to your water. Nuun and Liquid I.V. are popular brands readily available at Houston stores like Target and Kroger. Look for options with a good balance of sodium, potassium, and magnesium.
A common mistake is thinking that you only need electrolytes during your walk. Start replenishing electrolytes before you even head out the door. This will help your body stay hydrated and maintain proper electrolyte balance throughout your activity.
Recognizing the early warning signs of heatstroke is crucial. Don’t ignore these symptoms, even if you think you’re just “a little tired.”
Headache: A throbbing headache is often one of the first signs.
Dizziness: Feeling lightheaded or dizzy is another common symptom.
Nausea: Feeling sick to your stomach can indicate that your body is overheating.
Muscle cramps: Muscle cramps, especially in your legs or abdomen, are a sign that you’re losing electrolytes.
Excessive sweating (early on) or lack of sweating (later): Initially, you might sweat profusely. However, as heatstroke progresses, your body may stop sweating altogether. This is a dangerous sign.
Confusion or disorientation: If you start feeling confused or disoriented, seek medical attention immediately.
Rapid heartbeat: Your heart will beat faster as it tries to cool your body down.
If you experience any of these symptoms, stop walking immediately. Find a shaded area, drink water or an electrolyte beverage, and try to cool down. If your symptoms don’t improve quickly, seek medical attention. Don’t try to “tough it out.” Heatstroke can be fatal.
Here’s a specific scenario: You’re walking the White Oak Bayou Greenway Trail near downtown. It’s a beautiful trail, but it’s also exposed to the sun in many areas. You start feeling a headache and notice your heart is racing. You’ve been drinking water, but you realize you haven’t had any electrolytes.
What do you do? First, stop walking. Find a spot under one of the few trees along the trail. If you have electrolyte tablets with you, take one immediately. If not, try to find a convenience store or gas station nearby to purchase a sports drink. Pour some water on your head and neck to help cool down. If your symptoms don’t improve within 15-20 minutes, call 911.
Another challenge is acclimating to the Houston heat. If you’re new to the area, or if you haven’t been active outdoors in a while, start slowly. Don’t try to walk for miles on your first day. Gradually increase your activity level over time, allowing your body to adjust to the heat.
Consider wearing light-colored, loose-fitting clothing. Dark colors absorb more heat, while light colors reflect it. Loose-fitting clothing allows for better airflow, which can help your body cool down.
Finally, listen to your body. If you’re feeling tired, weak, or overheated, stop and rest. Don’t push yourself too hard, especially in the Houston heat. Your health is more important than finishing your walk.
Walking outdoors in Houston during the summer requires careful planning and preparation. By choosing shaded routes, hydrating properly, recognizing the early warning signs of heatstroke, and listening to your body, you can enjoy the outdoors safely. Don’t underestimate the power of the Houston heat. Take it seriously, and you’ll be able to stay active and healthy all summer long.
