Hey there, welcome to paging Dr. Gupta.

Thank you so much for being here.

I love hearing your questions, hearing what's on your mind.

It is officially summer.

And before you head out into the sun, I want to remind you that heat can be dangerous.

In fact, here's something that surprises a lot of people.

Extreme heat is, in fact, the number one weather-related killer in the United States every year. But if you take precautions,

you pay attention, you should be just fine. And that's what we want to talk about today. Now,

one of the best things you can do is to really focus on your hydration.

But there's a lot that goes into that.

My producer, Jennifer, is here to tell me what listeners are asking about today.

Hi, Sanjay.

So we have a question from a soccer fan who saw that FIFA has introduced mandatory water breaks at the World Cup this year.

Now, this listener says he's heard of rules of thumb, like drink half of your body weight

and ounces, or even eight glasses a day.

But he wants to know if that's still the best guidance, and he also wants to know about

electrolytes.

Okay, it's a great question.

It's an important question, especially this time of

year. Between sweat and overhydration, the answer is more complicated than just drink lots of water.

I'll explain right after this short break.

Get the new Fix and Fall Tariff from British gas, where prices can only slide down.
