Parents across the UK are being warned to watch for eight specific signs of dehydration in babies and children as a heatwave pushes temperatures up to 38°C in parts of the country. The Met Office has issued a rare severe red weather warning, leading to school closures.
Key Signs of Dehydration
According to NHS guidance, dehydration occurs when the body loses more fluids than it takes in and can become dangerous if untreated. Dr Sarah Jarvis, GP and clinical consultant for patient.info, told The Sun that parents should be “particularly careful” with children under one year old, especially those aged six months and younger, born prematurely, or with low birth weight.
The eight symptoms parents should look out for include: fewer wet nappies or less frequent toilet use with dark, strong-smelling urine; no tears when crying; a sunken soft spot on the head (fontanelle); sunken eyes; irritability, drowsiness, confusion, or complaining of thirst; dry lips, mouth, or tongue; cold hands and feet despite the heat due to circulation shutting down; and faster-than-normal breathing or heartbeat.
Immediate Steps to Take
The NHS advises drinking fluids if dehydration symptoms appear. If feeling sick, start with small sips and gradually increase. Avoid caffeinated drinks and alcohol as they can worsen dehydration.
