According to the World Meteorological Organization (WMO) 2025 is likely to be one of the three warmest years for global average temperature.

So, if you're out in the heat and start to get these kinds of muscle spasms, it could be an early warning sign that your body is struggling with the high temperatures, and you need to take action to cool down and rehydrate.

However, if heat exhaustion progresses into heatstroke, it becomes a medical emergency that requires immediate treatment from healthcare professionals because it can be life-threatening if not addressed promptly.
