Heat advisories continue Tuesday

HORRY COUNTY, SC (WMBF) - The heat is sticking around as another heat advisory is in effect.

Doctors always worry about dehydration for anyone out in the sun too long for a day. But it's not just one day's trip to the beach you need to worry about. If you continue these bad habits for multiple days in a row, it could lead to bigger issues.

Dr. Dennis Rhoades, the regional medical director for Doctor's Care, says most people know by now that if you're light-headed or if you stop sweating or turn pale, those are obvious signs of heat stroke or dehydration. But what most people don't understand is that when you have several days of heat in a row, there is a cumulative effect as well, especially if you're on any medications.

If you take blood pressure medication with any diuretics, this make you more sensitive to the sun, says Dr. Rhoades. So if you're dehydrated and you're on diuretics, your kidneys could fail from that combination. The same goes for if you have a heart condition.

And doctors are warning it's not just how much you drink, but what you drink as well. “Sweet tea down here in the south is loaded with sugar,” warns Dr. Rhoades. “You can actually become dehydrated if you drink too much sweet tea. So not that you shouldn't have your soda and you shouldn't have your sweet tea, but you should supplement that. If you're going to have a glass of water and then you're also going to have a glass of sweet tea, well then you should probably have two glasses of water to make up for what that sweet tea did to your dehydration status.”

The human body is not made to withstand long periods in such high heat. So other than drinking more and using more sunscreen and taking breaks, you should seriously consider going to the beach earlier in the morning or after 5:00 p.m. when it's cooler.

If you're on the beach and feeling desperate for some water or like you might pass out, go to one of the life guard stations or find a beach patrol officer. They will have water with them.

It's not just your body that this extreme heat is having extreme effects on. It's also very harsh on your car. Gary Freeman at C&G Auto and Truck says the number one thing that will fail during the summer is your cooling system, which includes the radiator and the cooling fans. So make sure before you start up and head off on your summer road trip that your radiator overflow is full. And if you're not quite sure how to check it, make sure you have someone check it professionally. Your cooling fan is what cools the radiator while you're in traffic. If you turn your air conditioner on full blast, the cooling fans should automatically come on. If they don't, you need to have those checked and repaired.

 And don't forget that air conditioner. “It's a good idea to have you're A/C serviced every year,” says Freeman. “A professional service will tell if there is a component that is getting weak and getting to fail. And then you can catch something before it turns into a major expense.” If you don't take care of that air conditioning unit with a recharge every now and then, it could end up costing you thousands of dollars. A typical recharge will cost anywhere from $90 to $150.

Tires are also a big problem in the heat. When temperature rises, so does the tire pressure. So make sure they're inflated correctly. To check the PSI recommendations, you can usually find it in the inside of the frame of the driver's side door.

And now would be a good time to pull those car shades out and put in the back windows for your kids. Little kids can easily blister in the hot sun in the car in no time at all. It's a good idea, if you can, to travel early in the morning or late in the evening when the temperatures are cooler and your car doesn't have to work so hard to stay cool.
