Here’s why you should prioritize shade during your run:

1. Decreases your risk of heat exhaustion and heat stroke.
2. Helps maintain a lower core body temperature.
3. Provides relief from harsh sun exposure.
4. Allows for longer, more enjoyable runs in high heat.

Embrace shade to protect your body and boost your endurance when running in 90-degree weather.

Grass Versus Pavement

Although pavement may seem convenient, choosing grass or shaded paths can considerably reduce heat exposure during your run.

Pavement absorbs and retains heat, often reaching temperatures above 140°F on hot days. This can increase your risk of burns and heat-related stress.

Grass, on the other hand, stays cooler and helps prevent overheating by providing a softer, less heat-absorbing surface.

Running on grass or shaded trails also minimizes your contact with hot, reflective surfaces that elevate your body temperature.

By seeking out grassy, shaded routes, you not only improve comfort but also reduce the risk of heat exhaustion when temperatures hit 90 degrees or higher.

Whenever possible, prioritize grass over pavement to keep your body cooler and safer during summer runs.

Cooling Effects Outdoors

Choosing grass over pavement not only helps reduce heat exposure but also enhances your body’s ability to stay cool.

When you run on shaded routes and grassy paths, you benefit from natural cooling effects that pavement simply can’t offer.

Shade lowers skin temperature and cuts down on sunburn risk, while grass retains moisture and stays cooler than asphalt.

To maximize cooling outdoors, remember these tips:

1. Seek out shaded routes to minimize direct sun exposure.
2. Opt for grassy surfaces to promote better thermoregulation.
3. Use trees or structures as natural shade breaks during your run.
4. Avoid open, sun-drenched pavement during peak heat hours.

Staying cool is key, so make the most of your outdoor runs!

Acclimate Gradually to Hot Weather

When you gradually expose yourself to hot weather over 1 to 2 weeks, your body adapts by improving sweat efficiency and increasing plasma volume.

This process, known as heat acclimation, helps your thermoregulatory system work more effectively during runs in 90 degree weather.

To do this, focus on gradual exposure by slowly increasing your training duration and intensity each day.

Aim to spend 4-6 hours per week in warm environments to promote these beneficial changes.

During heat training, avoid pushing yourself to exhaustion early on; instead, prioritize steady, consistent effort to prevent heat-related illnesses.
