So now that this is well and truly a full-on heatwave, I thought I should pass along, for the safety of everyone, how to tell when you're suffering from heatstroke, or heat sickness, as some might call it.
The simplest way to tell is to check your body temperature, so I suggest keeping a thermometer handy. When your core temperature reaches above 40°C (or 104°F), and especially if you have stopped sweating, you are probably sick. Other symptoms include:
- Dizziness
- Hallucinations
- Headache
- Chills
- Nausea
- Pale or flushed skin
- Weakness or fatigue
- Appearing as though out of breath
If you or anyone you know seems to be experiencing these symptoms, move to a cool, shaded area immediately, and drink plenty of cool liquids, water being the most important, naturally. You may also use water to soak their clothes, or just to spray on them.
So it is my professional advice to carry a fan and a bottle of cold water with you as we trudge through this overwhelming heat. Stay cool and stay safe.
