For a country that treats 23 degrees Celsius like it is the Sahara, the UK isn’t exactly built for this kind of heat. While most of us are busy Instagramming sunsets, our bodies might be quietly waving red flags. And that tiredness or weird headache is not just the heat; it could be your system slowly giving signs.Here is what the heat could actually be doing to you and why you should not ignore it.That Headache Is a Heat AlarmYou’ve drunk your water, you're not hungover, and yet your head’s pounding like you’ve been at a rock concert. Heat headaches are real, and they’re one of the first signs your body is overheating. So slam a glass of water, sit in front of a fan, and maybe ditch the hot coffee for something icy. It would help if you stuck your feet in a cold bucket like your gran used to do.Sweat, Then No Sweat? That’s TroubleAt first, you’re drenched like you’ve run a marathon in your own kitchen. But then… nothing. You stop sweating. Your skin feels dry, hot and honestly a bit different. This switch can be dangerous. It’s a classic heatstroke sign. Do not ignore if you’ve been roasting all day and your skin is suddenly dry and flushed; that’s your cue to cool down fast. Think cold compress, wet towel, or even lying in a bath.Muscles Twitching on Their Own?Random leg twitches? Sudden tummy cramps while lying down doing absolutely nothing? That’s not just your body being weird; it’s heat cramps. They happen when you’re low on salt and hydration, and they can be surprisingly painful. DIY remedy: Bananas, electrolyte sachets, or if you’re fancy, coconut water. Feeling Like You're About to Faint on the Road?Heat dizziness is uncertain. One minute you’re grabbing grapes; the next you’re gripping the trolley like it’s your last hope. When it’s hot, your blood pressure can drop faster than your motivation on a Monday. If you suddenly feel woozy or like you’re in a bad dream, sit down before you fall down. Always carry a water bottle. Can’t Think Straight? Not Just the Heat Making You DullIf you’re suddenly mixing up names, forgetting simple words, or spacing out mid-text, that could be the heat messing with your brain. Mental fog, confusion, or even irritability are signs that your body is cooking from the inside. If someone is slurring, looking spaced out, or acting like they’ve had a few too many but haven’t, it could be heatstroke. Call for help.Your Skin Feels Like a Radiator? Hot, dry, and suspiciously flushed skin is not the summer glow you think it is. If your skin starts feeling like it belongs in an oven, it means your body’s not coping well with the heat. Especially if your pulse is racing and you feel weirdly calm. Get help. This is your body in SOS mode. Cool off immediately and don’t try to “push through it”.Swollen Feet?Heat can make your feet and ankles puff up like inflatable pool toys. It’s not you gaining sudden water weight; it’s literally your blood vessels acting up. So put your feet up, wear comfy shoes, and avoid salty snacks. That means no crisp binge while complaining about the weather.Do Not Forget To:Hydrate wellDraw the curtains alwaysSit in front of a fan for reliefAvoid peak sun hours Don’t ignore what your body’s whispering
