The perception of temperature can vary depending on the climate and the level of acclimatization of a region's residents. The United Kingdom has a maritime climate, characterized by mild and damp conditions, with relatively cool summers and mild winters. As a result, temperatures above 30 degrees Celsius (86 degrees Fahrenheit) are relatively uncommon in the UK, and the infrastructure, housing, and cultural norms are not always designed to cope with such high temperatures.
In contrast, many states in countries like the United States experience a continental climate or other climatic conditions that frequently bring higher temperatures. People living in those regions are generally more accustomed to hotter weather, and the infrastructure and lifestyle are often built to accommodate it. Air conditioning is more prevalent in buildings, and measures are in place to mitigate the effects of heat, such as proper insulation, shading, and cooling systems.
When a region with a milder climate, like the UK, experiences a sudden spike in temperature to 30 degrees Celsius, it can be considered drastic because it exceeds the normal range of temperatures experienced there. The lack of widespread air conditioning in homes, offices, and public spaces can make it uncomfortable for people in the UK during such episodes of extreme heat. Additionally, the infrastructure may not be designed to handle such temperatures, leading to potential issues with transportation, power grids, and other services.
It's important to note that people's tolerance to heat can also vary based on personal preferences, health conditions, and individual sensitivity to temperature changes. What may be considered a comfortable temperature for one person might be uncomfortable or even dangerous for another.
