Lake Poway is one of the best hiking spots in the area, but once the weather warms up, it’s also where Rancho Bernardo chiropractor Dr. Cameron Sutter sees the most preventable dehydration complaints. A little planning before you hit the trail makes the difference between a great afternoon and a rough one.
How Much Water Do You Actually Need?
A good rule of thumb is a half a liter to a full liter of water per hour, depending on the heat. This time of year especially, it’s always better to carry more water than you think you’ll need than to run out halfway around the lake.
Signs of Dehydration on the Trail
Thirst and a dry mouth are the obvious early signs, but they’re rarely the first ones people notice. Watch for headache, fatigue, muscle cramping, or reduced energy as you hike. Dark urine, or simply not feeling the urge to urinate, is another warning sign worth paying attention to. Dizziness on the trail is one of the most dangerous signs of all, and it’s exactly when you’re farthest from help.
Getting Ahead of the Heat
Hydration starts before the hike, not during it. If you know you’re heading out for the weekend, start drinking more water a day or two ahead of time and skip the alcohol (it dehydrates you well before you ever lace up your boots). Don’t start an early morning hike on coffee alone. Electrolytes are worth adding to part of your water supply too, especially on hotter days when you’re sweating more than usual.
What to Pack for a Day Hike
Plenty of water and electrolytes come first, along with sunscreen, a hat, and a few healthy snacks (protein bars travel well and don’t melt). A small first aid kit, your phone, and good hiking shoes with real socks round out the list. Don’t underestimate blisters. They’re easy to shrug off, but they can quietly change your gait and lead to an ankle or knee injury before you notice what’s happening.
Does Dehydration Actually Cause Joint Pain?
“Muscle tension and joint pain aren’t what people usually think of with dehydration, they think of the dizziness and the headache. But muscle cramping, joint pain, and overall body tension from dehydration are very common,” says Dr. Cameron.
Best Time of Year to Hike Lake Poway?
Spring and winter tend to be the safest, most comfortable times to hike Lake Poway, with summer and early fall bringing more heat and less shade along the trail. Whatever season you go, light clothing, a hat, and steady hydration make the difference.
