Why is hot water good for stingray stings?
Hot water inactivates any remaining venom and may relieve pain.
Marine venoms consist of multiple proteins and enzymes, and there is evidence that these become deactivated when heated to temperatures above 50 °C. A long‐held view is that deactivation of these heat labile proteins by direct heat application leads to inactivation of the venom.
Stingray stings can be quite painful. Often, the pain peaks after about 90 minutes, although it may last for much longer. Soaking the affected area in hot water, if possible, can help relieve pain. Anti-inflammatory and pain medications can also help.
Soak the skin in hot water. Use water that's 110 to 113 F (43 to 45 C). It should feel hot, not scalding. Keep the affected skin immersed or in a hot shower until the pain eases, which might be 20 to 45 minutes.
Sting ray encounters are much more common in summertime because the fish like warm, clear waters, Parker said. They typically congregate around pier pilings, jetties and other structures in the ocean. Unseasonably warm waters in the low 60s also could be drawing more stingrays to the area, experts said.
Hot water immersion can be applied after initial treatment, but to be effective, heat needs to be applied as soon as possible after stinging. Apply hot, but not scalding, water (ideally at 42–45°C), or a heat pack for 30–90 minutes or until the pain resolves.
Stingray venom is a very heat sensitive protein. The recommended initial treatment is immersion in hot water that patients maintain at a temperature of 110º to 115º (if tolerable) for 30 to 90 minutes. Heat in theory rapidly denatures the venom protein, providing significant and rapid pain relief.
Heating all venoms led to the denaturation and loss of some proteins; however, most of the venoms retained a significant number of proteins. Seventeen venoms contained more than seven proteins after heating, whereas five venoms contained only one to three proteins.
These findings suggest that after an hour of heating most toxic components in snake venom were already destroyed and heating could be used as a simple technique to detoxify cobra venom. In cobra venom, the major components are cardiotoxins and neurotoxins.
Symptoms and Signs of Stingray Stings
Although often limited to the injured area, the pain may spread rapidly, reaching its greatest intensity in < 90 minutes; in most cases, pain gradually diminishes over 6 to 48 hours but occasionally lasts days or weeks.
What is the pain level of a stingray sting?
The sting of a stingray causes a bleeding wound that may become swollen and turn blue or red. It causes excruciating pain and can result in death. Severe symptoms may include nausea, fever, muscle cramps, paralysis, elevated heart rate and seizures.
One of the cures commonly asked about is urine. Shawn asked San Diego City Lifeguard Sergeant Charles Knight if urinating on a stingray injury alleviates pain. He says this claim is FALSE. Another remedy often discussed is hot water.
There is good evidence immersing someone in hot water works when treating bluebottle stings. Hot water inactivates the jellyfish toxins and so stops the pain; it is effective in about 90% of cases after 20 minutes.
If medical attention is not readily available, the following guidelines are recommended in treating a stingray sting: Flush the wound with fresh water. For pain relief, soak the wound in water as hot as the person can tolerate (approximately 110 F, 43.3 C). Use tweezers to remove the stingers.
First aid for insect bites and stings
Apply a cold compress (such as a flannel or cloth cooled with cold water) or an ice pack to any swelling for at least 10 minutes. Raise or elevate the affected area if possible, as this can help reduce swelling.
Water Requirements for Stingrays
Most freshwater rays can be kept at a pH between 6.8 and 7.6, alkalinity between 1° and 4° (18ppm to 70 ppm) and temperature between 75° and 82° F. Ammonia and nitrite levels should always be zero and nitrates below 10 ppm.
The best way to prevent being stung by a stingray is to avoid stepping on it when in the ocean by shuffling through the sand rather than lifting your feet and walking normally (commonly referred to as the "stingray shuffle"). This will warn a stingray of your approach, and it will likely swim away.
Avoid making contact with a stingray barb by shuffling your feet from side to side as you walk into the water. This will ensure you never step on a stingray and decrease your chances of getting stung.
Soaking in warm water often can help reduce your pain and stiffness and the benefits. There are many reasons soaking in warm water works. It reduces the force of gravity that's compressing your joint. Water offers 360-degree support for sore limbs, can decrease swelling and inflammation and increase circulation.
Improved circulation
Hot water is a vasodilator, meaning it expands the blood vessels, improving circulation. This can help muscles relax and reduce pain.
Do you put ice or heat on sting?
Apply a cold or ice pack wrapped in a thin cloth to help reduce swelling and pain (10 minutes on and 10 minutes off for a total of 30 to 60 minutes). If the sting happens on an arm or leg, keep the arm or leg raised to help reduce swelling.
Wash it with fresh water; that makes it sting worse. Here's what to do: Bathe the stung area in sea water and carefully remove any remaining stingers. Douse with vinegar if available, but a better bet is to get home, shower or soak it in water as hot as you can comfortably stand.
The primary predators of southern stingray adults are hammerhead sharks. Both scalloped hammerheads and Great Hammerheads have been observed using their wide heads to pin stingrays to the seafloor, wildly biting them until they can no longer move.
Pain is immediate and severe, gradually diminishing over 6 to 48 hours. Many people with these wounds experience fainting spells, weakness, nausea, and anxiety. Vomiting, diarrhea, sweating, generalized cramps, breathing difficulties, and death are less common. (See also Introduction to Bites and Stings.
Vinegar is used to stop the venom in stingers. Caution: Do not use ammonia, urine, rubbing alcohol, fresh water or ice. They all can trigger the release of more venom. If you don't have vinegar, move on to scraping off the stingers.
And once that paralysis hits your diaphragm and rib muscles, you only have a few minutes before you suffocate to death. No, the fastest-acting venom on Earth belongs to the Australian Box Jellyfish or sea wasp. It's not the most potent venom out there. But encounter one of these guys and you'll be dead in 15 minutes.
Boiling, unlc-ss continued for a long time, does not render the fluid harmless. Alcohol has long held the first place in popular esteem as an antidote for snake poison.
His symbiote is black and white, with his face almost covered in a corrupted version of Spider-Man's mask. As Venom, Brock could exhibit super strength and immunity to the powers of other heroes like Ghost Rider's Penance Stare and Spidey's spider-sense. Venom is weak to fire and sonic energy, however.
The Venom symbiote has two major weaknesses - sound and fire. Loud noises cause the symbiote to writhe in pain. That's how Peter Parker originally freed himself of the symbiote. A tolling church bell drove the two apart and sent the fleeing symbiote straight into the arms of an unsuspecting Eddie Brock.
“It is important to note that this resistance is not absolute – we are not immune to cobra venom, just much less likely to die than other primates.” Resistance to cobra venom has a cost – receptors that are resistant to cobra venom don't work quite as well.
What is the ideal temperature in treating a stingray sting?
For pain relief, soak the wound in water as hot as the person can tolerate (approximately 110 F, 43.3 C). Use tweezers to remove the stingers. Scrub the wound with soap and fresh water. Do not cover the wound with tape or close it with stitches.
There is good evidence immersing someone in hot water works when treating bluebottle stings. Hot water inactivates the jellyfish toxins and so stops the pain; it is effective in about 90% of cases after 20 minutes.
The sting usually causes a sting mark, pain and swelling, which may last several days to several weeks. Both jellyfish and stingray stings also can cause life-threatening shock and allergic reactions.

There are several popular methods to relieving the pain of a jellyfish sting, one being to apply urine. However, one UAMS specialist says there is no evidence that this method works. “Despite what anyone tells you, do not apply vinegar, urine or meat tenderizer to the affected area,” UAMS neurosurgeon Dr.
Caution: Do not use ammonia, urine, rubbing alcohol, fresh water or ice. They all can trigger the release of more venom. If you don't have vinegar, move on to scraping off the stingers. Prevention.
Wash the wound with salt water (never fresh water, as it can rupture the stinging cells). Do not itch or rub the skin with sand or a towel, but do remove the remains of the tentacles if they are evident.
If you notice shortness of breath, excessive sweating, an irregular heartbeat or feelings of faintness, seek medical attention immediately. If the barb has pierced the throat, neck, abdomen, or chest, or has completely gone through part of the body, do not try to remove it. Instead, seek immediate emergency treatment.
Death is extremely rare and results not from the venom but from the puncture wound itself if it is in the chest, abdomen, or neck. Death from serious infections like tetanus has also been reported. Treatment of stingray injuries starts with first aid.
These ancient fish, little changed over many millions of years, can reach 16.5 feet long, including the tail. There are reports of giant stingrays weighing up to 1,300 pounds, though such accounts are not verified because weighing the enormous and awkward animals is very difficult.
