Europe may face another dangerous heatwave in the coming days, with the World Health Organization warning that several countries could see more deadly weeks of extreme heat.
Temperatures in Portugal and southern Spain are expected to rise close to 43°C in some areas. Health officials are concerned because many parts of Europe have already faced severe heat in recent weeks.
The World Health Organization said extreme heat can be especially dangerous for elderly people, children, outdoor workers and people with heart, breathing or other health problems.
A new heatwave is developing over the Atlantic and may affect several European countries. Officials are asking governments to prepare hospitals, emergency services and public health teams for possible heat-related illness.
Portugal and Spain May See 43°C Temperature
Portugal and southern Spain are expected to face some of the highest temperatures during the new heatwave.
At 43°C, people can face dehydration, heat exhaustion and heatstroke if they remain outside for long periods without water or shade.
Heatwaves also put pressure on electricity systems because more people use air conditioners and fans. In some areas, water demand can also increase sharply.
Authorities may issue heat alerts and ask people to avoid outdoor work during the hottest hours of the day.
WHO Asks Countries to Prepare
The WHO held an emergency discussion with representatives from 41 countries, the European Commission and civil society groups to review the recent heatwave and prepare for the next one.
The organisation said countries with proper heat-health plans were able to respond faster and protect more people.
Such plans include public warnings, cooling centres, emergency medical support and special help for elderly people living alone.
Health officials are also advising people to drink water regularly, wear light clothes and avoid direct sunlight during afternoon hours.
Heat Can Be Deadly for Vulnerable People
Extreme heat does not affect everyone in the same way.
Older people, babies, people with health conditions and workers who spend long hours outside are at higher risk.
People living in crowded homes without cooling systems can also face serious problems during long heatwaves.
Doctors say heatstroke can become dangerous very quickly. Symptoms may include dizziness, headache, weakness, confusion, heavy sweating or loss of consciousness.
People who show serious symptoms should receive medical help immediately.
Climate Change Increases Heatwave Risk
Scientists have warned that climate change is making heatwaves more frequent and more intense.
Europe has experienced several record-breaking summers in recent years. High temperatures have affected farming, water supply, forests and public health.
Heat can also increase the risk of wildfires, especially in dry areas of Spain, Portugal, Italy and Greece.
Governments are now under pressure to improve heat warning systems and prepare cities for hotter summers.
The coming days will be important as authorities monitor temperature forecasts and issue safety alerts for the public.
