If this Fourth of July is anything like the last national holiday, Memorial Day, families and travelers headed to the beach will want to keep their eyes peeled to the sand and the sun, not just the fireworks-drenched sky.

Beachgoers who braved the Florida coastline Memorial Day weekend were greeted with the wrong kind of bang, hundreds of painful stings. Because of steady Atlantic winds, the beaches were swamped with reddish-colored jellyfish, known as mauve stingers, resulting in more than 800 reported stings among the beachgoers.

Now that summer has started, the Florida jellyfish debacle is a sharp reminder of the many stings, burns, nips, bites and rashes that arise when the temperature heats up and people head outdoors.

ABC news spoke with pediatricians, dermatologists and emergency medicine experts to pull together a guide to preventing, identifying and treating the various ills that can accompany your summer fun.

Whether you're headed to the beach or just outside to your backyard, read on to protect yourself from enduring the stings of summer.

When Jellyfish Attack

Although there are many different species of jellyfish throughout the coastal United States, the resulting sting is largely the same. When you come into contact with a jellyfish, either underwater or when they're beached on land, small barbs in the tentacles catch on your skin and cause red welts.

If you think you've been stung by a jellyfish (and given how painful a jellyfish sting is, you usually know it), the best thing to do is rinse the sting in saltwater, not freshwater, says Dr. Lee Winans, head of the emergency room at Lawnwood Regional Medical Center in Fort Pierce, Fla.

"The little barbs are packets of poison, and if you use freshwater, it will cause them to rupture and make the reaction worse," he says.

Rubbing or patting the area can also cause these packets to rupture, so take a shell or credit card and scrape the barbs off the area while rinsing in the saltwater, says Dr. James Schmidt, a pediatric emergency medicine physician at Children's Hospital of the King's Daughters in Norfolk, Va.

There are a lot of old wives' tales or home remedies concerning jellyfish stings. Some people say you should pee on the sting, others say to use vinegar or meat tenderizer on them. These remedies can be somewhat helpful because they neutralize the jellyfish venom to an extent, says Winans, but ER doctors would use ammonia to do that.

If the stings cover a large portion of the body, systemic reactions such as nausea, vomiting and breathing problems can occur in some people and these symptoms should be checked out by a medical professional right away. Otherwise, use topical hydrocortisone cream and hot or cold compresses (whichever feels best).

Sun Burn vs. Sun Poisoning

We all know we should be wearing sunscreen, but sunburns still happen. The question is, when is a sunburn more than just an aloe-vera-and-sit-in-the-shade-for-a-few-days type of affair?

When sunburn is severe, causes blisters or covers a large part of the body, it can result in sun poisoning; an extension of heat stroke that is marked by dehydration, fever and headache.

Sunburn is a form of inflammation, so when a significant area of skin is inflamed, the body reacts to the inflammation with flu-like symptoms, says Dr. Neil Korman, a dermatologist at University Hospitals Case Medical Center in Cleveland.

It is most dangerous in the very young and the very old, and if acute sunburn is accompanied by vomiting, you should seek medical attention as rehydration with IV fluids may be necessary, Winans says.

The Bite from the Mystery Bug

Spiders, bees and chiggers -- oh my! For most people, summer months mean more hours spent outside in the woods, the grass or out on the beach, but vacationers aren't the only species to flood the outdoor arena. Various members of the insect animal kingdom will be out in full force this summer, so it's important to know which pests are merely pesky, and which ones might cause for worry.

Bees and hornet stings are usually not problematic unless you are allergic to their sting or if multiple stings are received at once. Wheezing or excessive swelling around the face or site of sting should be checked out by a doctor immediately, especially if it seems the person is having an allergic reaction to the sting, says Winans.

As for spider bites, most are harmless, but a few species of poisonous spiders can cause more serious reactions. In the southern U.S., brown recluse spiders can result in large, painful bites that, left untreated, can lead to loss of a limb. Unlike normal spider bites, which get better over the course of a few days, poisonous bites will only get worse and the skin around the bite can start to die, Winans say.

"Recluse and black widow," which are native to Florida, "bites will be quite painful, and the pain will migrate to other parts of the body," he says. "The bites can turn yellow and look almost like an egg white with a bubble," he says. They should be seen by a medical professional immediately.

Chigger, mosquito and fire ant bites, while painful and itchy, are benign. They usually appear as small itchy bumps, or in the case of ant bites, small pus-filled bumps. "Put topical over-the-counter steroid cream on bites, but try not to itch them, that will only open them up to a possible infection," Winans says.

Lyme's Disease: Beware the Bull's Eye

A bite from a tick is usually not felt and will not itch, but if the tick is a carrier for Lyme disease, the resulting infection can be severe. The Northeast and upper Michigan are high-risk areas for contracting Lyme disease, according to the Centers for Disease Control and Prevention, but ticks can be found in other regions of the United States as well.

The easiest way to diagnose Lyme disease is by the red ring rash that often, but not always, accompanies a bite by a tick with Lyme. The "bull's-eye rash" will develop three to 30 days after a bite and will be accompanied by fatigue, chills, fever, headache, muscle and joint aches, and swollen lymph nodes, according to the CDC.

If you remove a tick from you and experience these symptoms following (even without the rash), see a doctor to get tested for Lyme disease, doctors say, because if not treated with antibiotics, Lyme can cause neurological, joint and cardiac problems over time, says Korman of U.H. Case Medical Center.

To avoid getting bit, walk in the center of trails and avoid walking through high brush. Also, check the body for ticks after hiking, especially warm areas such as scalp, groin and armpits.

Rash Reaction

Rashes can result for a number of reasons; from an allergic reaction to fabric to a poisonous plant. The most common rashes seen by doctors during the summer are heat rash, swimmer's itch and rashes from poisonous plants such as poison ivy, sumac and oak.

Swimmer's itch consists of many small, itchy, slightly painful red bumps that are usually noticed following a swim in the ocean. Usually, the rash is just another form of a jellyfish sting and results when microscopic jellyfish larva get caught in the fabric of one's swimsuit, says Schmidt.

Swimmer's itch can also be caused by other parasites present in fresh or saltwater. The rash is benign and can be treated with topical hydrocortisone cream but will otherwise go away on its own, doctors say.

Heat rash is not from contact with any plant or animal but merely the product of skin irritation in damp or sandy conditions, such as wearing a wet bathing suit over an extended period of time. The red, raised, itchy bumps are sometimes referred to as "prickly heat" and occur when the sweat glands become clogged, says Korman.

Rashes from poison oak, poison ivy or poison sumac are par for the course for summertime excursions into wooded areas, and while annoying, are usually not serious. About 85 percent of the population will develop an allergic reaction if exposed to poison ivy, oak or sumac, according to the American Academy of Dermatology.

The itchy, blistering rash usually develops 12 to 72 hours after exposure and can be treated with calamine lotion and time. If swelling becomes serious, affects breathing and causes eyes to swell shut, seek medical attention immediately.
