Hydration in the desert: when IV therapy helps, and when it doesn't

In Arizona, sweat evaporates almost as fast as you make it, so you can lose a lot of fluid without noticing. After years in emergency medicine, I’ve seen how quickly mild dehydration turns into something more serious in our heat.

Signs you’re running low

• Thirst, dry mouth or dark yellow urine

• Headache or fatigue that builds through the day

• Dizziness when you stand up

• Muscle cramps after activity

Start with what you drink

For most people, most of the time, water plus electrolytes is enough. Drink before you’re thirsty, add electrolytes on long or hot days outdoors, and eat water-rich foods like fruit and vegetables.

When IV hydration can help

An IV delivers fluids and electrolytes directly into your bloodstream, so you rehydrate faster than drinking alone. Patients often come in after long days outside, around travel, after hard training, or when a demanding week has left them depleted. Vitamins can be added based on your needs. Every IV at Lovena starts with a health screening, because conditions like heart failure and kidney disease change what’s safe.

When to skip the IV and call 911

Confusion, fainting, chest pain, hot and dry skin, or a temperature of 103°F or higher can signal heat stroke. That’s an emergency. The same goes for vomiting that won’t stop or not being able to keep any fluids down.

To book an IV session, call or text (484) 350-5145.
