Florida Heat Alert from Dr. Tieche: Don’t Wait Until You’re Thirsty

I wanted to pause our regular travel-prep series for a moment because we are seeing something right now at Recharge Clinic that I do not want people to ignore.

Patients are coming in dehydrated, depleted, lightheaded, weak, and just not feeling like themselves. We even had a patient pass out over the weekend from dehydration.

And I’ll be honest — people are kind of dropping like flies right now.

That may sound dramatic, but this Florida heat came on fast. We had a long stretch of beautiful weather, and then suddenly it got hot. Really hot. People are spending more time outside again, but their hydration habits have not caught up.

So before you head to the beach, boat, pool, golf course, tennis court, pickleball court, outdoor concert, or Memorial Day gathering, I want you to take hydration seriously.

Not once you feel bad.

Not once you feel thirsty.

Before that.

The Heat Came On Fast — And Your Body May Not Be Ready

One of the biggest issues I am seeing is that people are going from being indoors, in air conditioning, to spending hours outside in the Florida heat.

I want you to enjoy those outdoor activities, but I also want you to understand what this heat is doing to your body.

When you are outside in the heat, you are losing fluid through sweat. You are losing salt and electrolytes. Your blood vessels widen in response to the heat, which can make you feel weak, lightheaded, dizzy, or faint.

And the part people underestimate, is it can happen quickly.

You may feel fine, and then suddenly you feel shaky, nauseous, dizzy, crampy, or like you need to sit down immediately. That is your body telling you it is behind.

If You Feel Thirsty, You Are Already Behind

Please do not use thirst as your hydration reminder.

By the time you feel thirsty, you may already be dehydrated — especially in Florida heat, humidity, direct sun, or after alcohol.

Hydration is not something you “catch up on” once you already feel terrible. You need to start before you leave the house and continue throughout the day.

That means drinking water before you get in the car. Before you get on the boat. Before you tee off. Before you walk into the concert. Before you start drinking alcohol.

If your first real water of the day is when you already feel dizzy, weak, or nauseous, you waited too long.

You Can Be in the Pool and Still Be Dehydrated

This is something I really want people to understand.

You can be in the pool and still be dehydrated.

You can be on a boat and still be dehydrated.

You can be at the beach with your feet in the water and still be dehydrated.

Being near water can make you feel cooler, but it does not mean your body is hydrated. You are still sweating. You are still in the sun. You are still losing fluid and electrolytes. And if you are drinking alcohol, your risk goes up even more.

That is why so many people get caught off guard. They think, “I’m fine, I’m by the water,” and then all of a sudden they feel awful.

My Hydration Rule: Start Before You Go

Here is what I want you to do before any outdoor plans:

Start drinking water early in the day.

Bring more water than you think you need.

Keep water with you, not just nearby.

Sip consistently throughout the day.

Take breaks from the sun.

Eat real food.

And if you are going to be sweating, exercising, drinking alcohol, or spending several hours outside, consider electrolytes.

For many people, water plus electrolytes can make a big difference in the Florida heat. That does not mean everyone should start loading up on salt. If you have high blood pressure, kidney disease, heart disease, fluid restrictions, or take diuretics or certain blood pressure medications, ask a medical professional what is appropriate for you.

But for the average person spending hours outside in this heat, especially if alcohol or exercise is involved, plain water alone may not be enough.

Alcohol Makes This Worse

With Memorial Day coming up, I need to say this clearly: alcohol and Florida heat are not a great combination.

If you are drinking outside, you need to be much more intentional about hydration.

Do not count alcohol as hydration. Do not wait until the end of the day to start drinking water. Do not assume you can fix everything the next morning.

If alcohol is part of your plans, drink water before you start, alternate alcohol with water, eat food, take shade breaks, and consider electrolytes when appropriate.

And if you know you tend to feel depleted, hungover, weak, or dried out after a weekend in the heat, Recharge Clinic is here to help.

Where IV Hydration Therapy Can Help 

At Recharge Clinic, IV hydration therapy is one of the tools we use to help patients support hydration and recovery.

Some patients use IV hydration proactively before a big weekend, trip, boating day, golf tournament, outdoor event, or several days in the heat. Others come in afterward because they feel depleted, weak, headachy, foggy, lightheaded, or like they cannot catch up no matter how much water they drink.

I want to be clear: IV hydration does not replace drinking water. It does not mean you can ignore hydration all day, drink alcohol in the sun, and expect an IV to undo everything.

That is not the goal.

The goal is to support your body before you get severely behind, or help you recover when you already feel depleted.

If you have multiple days of outdoor plans coming up, or if you already feel like the heat has taken it out of you, IV hydration therapy may be something to consider.

Do Not Ignore These Symptoms

Please pay attention if you start feeling:

• Dizzy
• Weak
• Lightheaded
• Headachy
• Nauseous
• Crampy
• Foggy
• Extremely thirsty
• Like your heart is racing
• Like you need to sit or lie down
• Like you cannot catch up on fluids

If this happens, get out of the heat. Cool down. Stop drinking alcohol. Sip fluids. Use electrolytes if appropriate. Do not keep pushing through because you are at an event or do not want to interrupt the day.

Your body is giving you a warning.

Listen to it.

And if someone faints, becomes confused, has chest pain, shortness of breath, repeated vomiting, severe weakness, or symptoms that are getting worse, seek urgent or emergency care immediately.

Blunt Hydration Check: Make Sure You Are Peeing

I’m going to be very blunt here because this is one of the easiest ways to know you are getting behind:

Make sure you are peeing.

If you have been outside in the heat for hours and you are barely urinating — or not urinating at all — that is a problem. If your urine is very dark, or you realize you have gone most of the day without using the bathroom, you are likely dehydrated and your body is trying to hold onto fluid.

This is not something to brush off.

You should be drinking enough that you are urinating regularly throughout the day. It does not need to be perfectly clear, but it should not be dark, concentrated, or absent for hours while you are sweating in the Florida heat.

So yes, I am going to say it simply:

If you are not peeing, you are behind on hydration. Pay attention, get out of the heat, start hydrating, and do not keep pushing through.

My Message Before Memorial Day Weekend

I want you to enjoy Florida. I want you to enjoy the beach, boating, golf, tennis, pickleball, concerts, travel, and time outside with family and friends.

But I also want you to respect the heat.

This weather can take people down quickly when they are not prepared.

So here is my reminder:

Hydrate before you go. Keep water with you. Drink consistently. Add electrolytes when appropriate. Be careful with alcohol. Do not wait until you are thirsty. And if you feel depleted, weak, lightheaded, or like you cannot catch up, Recharge Clinic is here.

We offer IV hydration therapy and vitamin therapy for patients who want to be proactive before a busy stretch of heat, travel, outdoor activity, or alcohol — and for patients who need help recovering afterward.

Do not wait until you are “dropping like flies.”

Take care of your body before the heat gets ahead of you.

Quick FAQs About Dehydration and IV Hydration

Can I get dehydrated even if I am in the pool or at the beach?

Yes. Being near water may make you feel cooler, but you can still lose fluid through sweating, sun exposure, heat, alcohol, and activity.

Is thirst a good hydration reminder?

No. In Florida heat, thirst often means you are already behind. Start drinking water before you leave the house and continue throughout the day.

Can IV hydration therapy help before a big outdoor weekend?

It may help support hydration before several days of heat, travel, boating, golf, outdoor events, or alcohol. It should be part of a bigger hydration plan, not a replacement for drinking water.

Can IV hydration therapy help after heat exposure?

Yes, it may help some patients who feel depleted, weak, foggy, headachy, lightheaded, or like they cannot catch up after being in the heat.

Does Recharge Clinic offer vitamin in the IV therapy?

Yes. Vitamins are added when to support energy, wellness, immune function, and recovery based on your symptoms, goals, and health history.
