HEAT STROKE
Heat stroke can kill or cause damage to the brain and other internal organs. Although heat stroke mainly affects people over age 50, it also takes a toll on healthy young athletes.
Heat stroke often occurs as a progression from milder heat-related illnesses such as heat cramps, heat syncope (fainting), and heat exhaustion. But it can strike even if you have no previous signs of heat injury.
Heat stroke results from prolonged exposure to high temperatures — usually in combination with dehydration — which leads to failure of the body’s temperature control system. The medical definition of heat stroke is a core body temperature greater than 104 degrees Fahrenheit, with complications involving the central nervous system that occur after exposure to high temperatures. Other common symptoms include nausea, seizures, confusion, disorientation, and sometimes loss of consciousness or coma.
Here’s what we’ve seen:
- Temperatures hit 38.6 C (101.5 F) in Coschen, near the German-Polish border, setting a new German national record for June, The Associated Press (AP) reported.
- Four out of five measuring stations across the Czech Republic have seen new daily records being set this week, with the temperature in the northern town of Doksany reaching a national high of 38.5 C (101.3 F).
- Most of France is expecting temperatures of at least 35 C (95 F) on Thursday, the national weather agency Météo France reported.
- Areas in southern France are forecast to reach as high as 44 C (111.2 F) on Friday, Météo France said. It could break the country’s highest-ever temperature of 44.1 C (111.4 F), which was recorded in August 2003.
- Temperatures in Milan are forecast to hit 40 C (104 F) this week, the AP reported.
- Berlin is expecting temperatures as high as 38 C (100 F) on Thursday, the BBC said. Major cities like Frankfurt and Hamburg are also expecting temperatures in the mid-30s Celsius (about 95 F).
- Most of Spain is expecting temperatures in the mid-30s Celsius (mid-to late 90s F) on Thursday, with the northern cities of Lleida, Logroño, and Zaragoza forecast to hit 41 C (105.8 F), according to government weather agency Aemet.
- Many locations in Switzerland broke their June temperature records on Wednesday, national weather agency Météo Suisse said. Large swaths of Switzerland are expecting temperatures of more than 35 C (95 F) on Thursday.
- Temperatures in Portugal are expected to hit mid-to-upper 30 degrees Celsius (upper 90s Fahrenheit) and could further rise to more than 40 C (104 F), Axios reported.
- Parts of Poland are also expected to see temperatures rise to at least 35 to 40 C (95 to 105 F) this week — which is at least 11 to 17 C (20 to 30 F) above normal, The Washington Post reported.
