Why does the formation of kidney stones increase with higher temperatures? And how much water should you drink to reduce the risk? How does heat affect the body?
Why does the formation of rocks increase with increasing temperatures?
Doctors are seeing an increase in the number of kidney stones as the weather warms up, according to a report at the Cleveland Clinic.
Kidney stones are irregularly shaped solid formations, formed from minerals and acid salts. It can move to the ureter, the tube that connects the kidneys to the bladder, causing severe lower back pain and groin discomfort.
summer moving pebbles
Usually more people go to the emergency room for kidney stones in the summer than in the winter months, and the reason is that about 80% of kidney stones are calcium-based, which is called when there is too much of it in the urine. hypercalciuria.
calcium in urine
“What we do know is that this excess calcium in the urine can eventually develop into kidney stones,” explains urologist Dr. Saray Cevalingam.
“Physical activity can protect you from developing kidney stones, so if you, like many of us, are less active in the winter, it also increases your risk of developing kidney stones. When the weather warms up, higher temperatures and dehydration lead to more growth. ” For pebbles that formed during the winter months and can suddenly move. ”
“Kidney stones cause pain when the ureter, which is only 2 to 3 millimeters wide, is obstructed and shrinks in an attempt to push the stone into the bladder. It causes severe discomfort in the lower back and / or groin and is often associated with nausea and vomiting, “says dr. Cevalingam. .
Kidney stones range in size from as small as a grain of salt, to as large as a golf ball, and affect both men and women almost equally.
The smaller the size of the kidney stone, the more likely it is that it will pass through the urinary tract without medical treatment.
If you suffer from kidney stones, you may also experience blood in the urine, fever, chills, nausea and vomiting, in addition to the constant urge to urinate.
Protection against kidney stones in summer
Once you develop a kidney stone, you have a 50% risk of developing another stone within the next five years, and this risk usually increases as you get older.
While there is no way to completely prevent kidney stones from forming, there are several things you can do to reduce your risk.
And if you want to reduce your risk of developing kidney stones, eating more fruits and vegetables can help, which makes urine less acidic and reduces the risk of stones.
Salt should also be avoided to reduce calcium in the urine. Generally, if you follow a diet that contains a large amount of sodium, work to reduce those foods and refrain from others.
Salty foods can include packaged meals and snacks such as chips.
See a doctor or dietitian about dietary changes if you feel you are at risk of developing kidney stones.
Dr. Cevalingam recommends that a person at risk of developing kidney stones drink enough fluids to produce at least 2.5 liters of urine per day, especially during the summer.
Dilute urine to reduce the risk of kidney stones
“Drinking a lot of water will help dilute the urine and reduce the formation of crystals such as calcium oxalate, which is the substance that makes up most types of kidney stones,” says Cevalingam, advocating to make sure you drink enough fluids.
Cola and other soft drinks contain phosphoric acid, which is believed to promote the formation of kidney stones. Therefore, the German Urological Association advises patients to avoid soft drinks altogether, according to Deutsche Welle.
Can we really die of heat?
In an article published by the French newspaper Le Parisien, the author Ines de Rossier asks: “Can we really die of heat?”
This will most likely happen, says Tibo Laconde, a specialist in climate issues, noting that once our bodies are exposed to a certain temperature, they will eventually succumb.
According to Laconde; When we reach this stage, “our temperature regulation mechanisms should not work,” while the author says to maintain a good temperature – which is about 37 degrees Celsius – our body uses two methods; The first is heat conduction and contact with air and the second is sweating.
Heat places a great burden on the human body
Evaporation of sweat will cause the person to cool down. According to Laconde, “in a dry environment, the body can withstand high temperatures of 45 and 50 degrees Celsius,” but in a humid environment; Our resistance is much lower, because when the air is saturated with moisture, the sweat does not evaporate and does not cool the body, and Laconde concludes that “with a relative humidity of 100%, the maximum temperature in the range of 35 degrees Celsius. “
Experts warn that with climate change this threshold can often be reached.
But for Tibow, the problem is not necessarily at this deadly temperature threshold; “Heat really kills before it gets to this point,” he says.
