HOT TAKE Warning over 'dangerous' method most use to reduce a child's fever after mum's 'mistake' almost cost her son's life
WHEN your child has a fever, reaching for a cold flannel might seem like an obvious fix.
However, doctors generally advise against it, as it can sometimes make the fever worse or trigger serious complications.

"If a child is suddenly cooled too rapidly, particularly if they already have a high fever, this can sometimes lead to a rapid shift in body temperature," Dr Suzanne Wylie, GP and medical adviser for IQdoctor, told Sun Health.
"In rare cases, this can increase the risk of a febrile seizure - especially in young children who are already susceptible."
And although these types of seizures are generally brief and not harmful in the long term, they can be very frightening for parents.
"It's much safer to reduce temperature gently and gradually," she adds.

The warning comes after Dr Christabel Akinola shared a tale on Instagram about a mum who sponged her child with cold water from the fridge when she noticed he was burning up.
The parent sponged his chest, back, neck and head, the doctor explained in a social media post.
The boy then shivered violently and stopped moving – he was then rushed to hospital.
'Do you know that you should not use cold water for tepid sponging during a fever?' Dr Akinola, said.

She said the sudden temperature contrast 'can trigger a seizure or even collapse the cardiovascular system'.
This is because applying something cold to the skin causes the blood vessels near the surface to constrict, in a process called vasoconstriction, Dr Suzanne explained.

"This response reduces heat loss through the skin and can trap heat deeper in the body, potentially making the fever worse," she said.
This level of stress on the body can also impact the heart and circulatory system.

"In extreme cases, this could lead to serious complications, such as a heart attack or shock, especially in vulnerable people, like young children," Dr Suzanne added.
On top of this, sudden exposure to cold can be uncomfortable for the child and may lead to shivering, "which in turn can increase the body's temperature," she added.
Instead of using a flannel, the best thing you can do for a child suffering from a fever is to keep them cool, not cold.

"Dress them in light clothing," Professor Franklin Joseph, consultant physician and head of Dr Frank's Clinic, also told Sun health.
"Keep the room at a moderate temperature, and ensure they're well hydrated," he added.
"You can also give age-appropriate doses of paracetamol or ibuprofen to help bring the fever down."

Let a fever run
That said, it is sometimes important to let a fever run its course.
'Fever is a natural and important part of the body's immune response," Prof Franklin said.
"When the body detects an infection, it raises its internal temperature because many bacteria and viruses cannot survive at higher temperatures," he added.
"In other words, the fever is a defence mechanism, helping the body fight off infection more effectively.'

'Automatically suppressing every fever can sometimes prolong illness by interfering with this natural response."
When to call for help
According to the NHS, parents should seek medical attention if their child is under three months old with a temperature over 38°C - or if the fever lasts more than five days.
"Other red flags include difficulty breathing, a rash that doesn't fade under pressure, seizures, unusual drowsiness, persistent vomiting," Prof Franklin said.
"Also look out for signs of dehydration such as a dry mouth and no wet nappies.
