Heatstroke symptoms: Key signs to look out for amid red weather warning

As the UK faces a record-setting heatwave with red weather warnings issued, people are being urged to spot the signs of heat-related illnesses.

Long periods in the sun can lead to heat exhaustion, a condition that occurs when your body overheats. Symptoms include nausea, headache, heavy sweating and dizziness.

According to the NHS, heat exhaustion can be treated by moving the affected person to a cool place, removing unnecessary clothing, drinking cold drinks and keeping the skin cool.

If not treated, it can turn into heat stroke, which can be potentially fatal. Symptoms include a very high tempature, hot skin without sweating and a fast heartbeat. You must seek medical help if you spot the symptoms of heatstroke.
