'I'm an expert and heatwaves do cause migraines here's how to stop them'

As the mercury rises across the UK, many Brits will be looking forward to soaking up the sun and spending time outdoors. However, for some, the onset of summer can bring about less desirable effects such as swollen ankles, dehydration, or migraines.

Migraines are defined as intense headaches, often accompanied by a pulsating pain on one side of the head. According to the NHS, these debilitating episodes can last anywhere from two hours to three days, with symptoms sometimes appearing up to two days before the headache itself begins.

Dr Ravina Bhanot, an NHS GP, has warned that heat and hot weather are among the most common triggers for migraines.

This is largely due to the fact that high temperatures cause blood vessels to dilate, leading to changes in blood flow to the brain.

Bright sunlight can also be a trigger for some migraine sufferers. During periods of hot weather, dehydration can set in, which subsequently impairs brain function.

For those susceptible to migraines, Dr Deepali Misra-Sharp advises staying in the shade, wearing sunglasses, staying hydrated, and not skipping meals. If you feel a headache or migraine starting, she recommends seeking out a cool, quiet space away from the heat, .

"Sip water slowly," she said. "A cold flannel or ice pack on the forehead or back of your neck can really help. Painkillers like paracetamol or ibuprofen can take the edge off, as long as they're safe for you."

Dr Misra-Sharp also emphasised the importance of timely intervention for migraine sufferers: "And if your headache comes on suddenly or feels very different from usual, don't ignore it - seek medical help."

For those who experience frequent migraines, especially more than once a week or in relation to their menstrual cycle, the NHS recommends consulting with a GP. Urgent medical attention should be sought if a migraine persists beyond 72 hours, or if one is pregnant or has recently given birth, by contacting 111 or arranging an urgent doctor's appointment.

In the battle against the heat, Dr Bhanot underscored the necessity of proper hydration, suggesting an intake of two to two-and-a-half litres of water during warmer weather. She added dark-coloured urine indicates a need for increased fluid consumption, and advised steering clear of excessive caffeine, fizzy drinks, and alcohol due to their dehydrating effects.

Dr Misra-Sharp continued: "Look at your wee - pale and straw-coloured is spot on. Darker? You probably need more fluids. Water is best, but tea, squash and water-rich foods like fruit help too."

Nutrition expert Rhiannon Lambert has warned against the dangers of drinking water too quickly, advising the public to "sip steadily throughout the day rather than chugging large amounts at once". Lambert also recommends getting hydration from food sources, highlighting that "Fruit and vegetables like watermelon, cucumber, strawberries, and courgette are naturally hydrating and provide essential vitamins, minerals, and antioxidants."

Adding her insight on seasonal eating, Rhiannon says when the temperatures soar, Brits should think about adjusting their diet to include lighter and cooler meals. She suggests: "Think fresh salads with protein-rich toppings, smoothies, or chilled grain bowls with plenty of colourful vegetables."
