Many of us believe that we are great drinkers and that alcohol does not affect us as much. People who are able to drink without showing any sign of inebriation are known as social drinkers. In short, they are not addicted to alcohol but will not turn down the opportunity to have a good time! While it may seem like it doesn’t affect you, new studies suggest that it is just an illusion, even if you have high tolerance, alcohol affects your cognitive and motor functions more than you think.

The study reveals the below implications and techniques:

  • Researchers used a new MRI technique to precisely measure brain electrical activity.
  • By comparing brain scans before and after drinking, scientists identified specific areas affected by alcohol and how much brain activity slowed down.
  • Participants were chosen to be regular social drinkers without alcohol addiction, ensuring the study focused on the effects of alcohol alone.
  • MRI technology provided reliable data on brain activity changes caused by alcohol consumption.

How does the brain react to alcohol?

The human brain is a complex network of billions of neurons that communicate through electrical impulses. Brain conductivity refers to the efficiency with which these electrical signals travel through brain tissue. It's akin to the speed and clarity of a digital signal through a wire. In layman terms, your brain must function in its peak condition as it is essential for various cognitive processes, including memory, attention, decision-making, and motor control.

Think of it as the foundation for your brain's performance. When brain conductivity is high, information flows smoothly, and that helps your brain in rapid processing and response. On the other hand, low conductivity can hinder cognitive function, leading to slower thinking, impaired memory, and difficulties with coordination.

A study conducted at the Neuroscience Research Australia (NeuRA) and UNSW Science unveiled a startling connection between alcohol consumption and brain conductivity.

What is the connection between alcohol consumption and brain activity?

While many people brush off the effects of alcohol as temporary changes in behaviour, the reality is much more complex. Beyond the obvious impacts on coordination and judgment, alcohol significantly alters brain function. Alcohol dramatically slowed down brain activity, especially in areas responsible for decision-making, planning, and physical coordination. This decline was so significant that it resembled the brain changes seen in normal ageing. This means even one drink could temporarily accelerate the ageing process of your brain.

Alcohol and Brain activity: What does the study Imply?

The implications of this research are far-reaching. It provides compelling evidence that alcohol consumption has a direct and measurable impact on brain function. The discovery that alcohol can significantly reduce brain conductivity opens new avenues for understanding the neurocognitive effects of alcohol abuse and dependence. While you may not feel like alcohol is affecting you and you have a high tolerance, it most definitely changes and affects your decision-making abilities and impulse control.

Furthermore, the MRI technique employed in the study could be a valuable tool for assessing the impact of other substances on the brain and for developing interventions to mitigate alcohol-related brain damage.

As several European countries grapple with severe heatwave conditions, the World Health Organization (WHO) has sounded the alarm, warning that rising temperatures are becoming a major public health emergency.

"Heat is no longer only a weather story. It is a health emergency," said Hans Kluge, WHO Regional Director for Europe, in a post on social media.

The warning comes as Europe faces another summer of extreme temperatures, with the global health organization linking the trend to "climate change, rapid urbanization, and an "aging population".

Heat An Urgent Public Health Threat

In its recently launched Heat-Health Action Plans Guidance, the WHO described extreme heat as an "urgent and growing public health threat."

The agency noted that rising temperatures increase illness and deaths, place additional strain on healthcare and social care systems, and disproportionately affect vulnerable groups such as older adults, children, people with chronic illnesses, and outdoor workers.

"Our Region is the fastest-warming region globally. In the past four years alone, heat has claimed more than 200,000 lives, while heat-related mortality has risen by 30% over the past 20 years," said Kluge, in an interview with BBC News.

He stressed that many heat-related deaths can be prevented through timely action and preparedness.

The WHO Europe also urged governments, employers, and institutions to strengthen heat action plans to protect vulnerable populations.

France

France is among the countries hardest hit by the current heatwave. Authorities expected 35 of the country's 96 departments to be placed under red heatwave alerts, with temperatures ranging from 39°C to 40°C across large parts of the country. Some areas could see temperatures climb to 41°C.

Officials have announced a partial alcohol ban in certain areas and strengthened wildfire preparedness measures. The government has also ordered increased monitoring of water supplies used to cool the country's nuclear reactors.

Germany

Germany has issued nationwide heat alerts as temperatures approach 38°C. The national weather service, DWD, warned that the combination of intense heat and humidity could trigger severe thunderstorms, adding another layer of risk to the ongoing heatwave.

Spain

In Spain, extreme heat forced the closure of a soccer fan zone, highlighting the impact of rising temperatures on public events and outdoor activities.

Portugal

Portugal is expected to experience its hottest conditions early next week. According to the Portuguese Institute for Sea and Atmosphere (IPMA), temperatures could reach as high as 42°C.

Italy

Italy is also preparing for a significant heatwave. Weather forecasts suggest temperatures in several northern and central cities could hit 40°C for the first time this year, affecting both residents and tourists across the country.

UK

The United Kingdom has also issued an extreme heat warning for early next week. The Met Office predicts temperatures could peak at around 34°C, with southern England expected to experience temperatures in the low 30s before the heat expands and intensifies on Monday and Tuesday.

Storm Alert

Alongside soaring temperatures, several European countries are facing the risk of severe storms. Meteorological agencies have warned that heat and humidity could fuel thunderstorms, increasing the likelihood of flash floods, strong winds, and other weather-related disruptions.

Kluge said that it is important to

  • warn communities early,
  • make cities cooler,
  • ensure access to water and shade,
  • check on those most at risk,
  • prepare health systems before temperatures peak.

How To Protect Yourself During Extreme Heat

To reduce the health risks associated with extreme temperatures, one should

  • Stay hydrated throughout the day
  • Seek shade and cooler indoor environments
  • Avoid outdoor activities during peak afternoon heat
  • Check regularly on elderly relatives, neighbors, and other vulnerable individuals
  • Follow public health advice issued by local authorities
  • Protecting outdoor workers from midday heat exposure.

The Ebola outbreak in the Democratic Republic of Congo (DRC) and Uganda, caused by the Bundibugyo virus, has reached 952 confirmed cases and 247 deaths, according to the latest update from the Africa Centres for Disease Control and Prevention (Africa CDC).

As of June 18, the DRC accounts for 933 confirmed cases and 245 deaths, while Uganda has reported 19 confirmed cases and two deaths. Uganda has not shown the same level of sustained transmission seen in

the DRC.

The overall case fatality rate currently stands at 25.9 per cent.

The outbreak caused by the Bundibugyo virus currently has no approved treatment or vaccine, complicating efforts to contain the disease.

Ituri Province Remains The Epicenter

Ituri Province continues to be the hardest-hit region, accounting for approximately 91 per cent of all confirmed cases. The main hotspots include Bunia, Rwampara and Mongbwalu.

Health officials are also concerned about North Kivu, where the case fatality rate has reached 58.4 per cent, with high mortality reported across several affected health zones.

The outbreak has now spread to 34 health zones in the DRC and one district in Uganda. In the DRC, the most affected provinces are Ituri, North Kivu and South Kivu. In Uganda, cases have been reported mainly in Kampala, including both imported and locally transmitted infections, the CDC said.

Treatment Centers Under Severe Pressure

The CDC said response teams continue to expand surveillance, case management, infection prevention and control measures, laboratory testing, border screening, risk communication and community engagement activities.

A new laboratory in Aru, Ituri Province, has become operational, increasing the total number of Ebola testing sites to six.

Despite ongoing efforts, the response remains under significant strain. Treatment centres are operating beyond capacity, with bed occupancy reaching 102% and 349 patients currently admitted across affected health zones.

The CDC also reported several operational challenges, including delays in patient referrals, shortages of ambulances and vehicles, gaps in personal protective equipment (PPE), and limited access to some affected areas.

Contact Tracing Challenges Persist

Surveillance and contact tracing teams continue to face obstacles, including incomplete addresses, delayed investigations and difficulties accessing certain communities.

More than 7,200 contacts have been identified across the two countries and are being monitored, the CDC said.

Africa CDC also estimates that $21.5 million is urgently needed to address critical gaps in the outbreak response.

Outbreak Outpacing Response Efforts

The outbreak's impact has been particularly severe among vulnerable populations. Last week, another six-month-old girl died from Ebola. She was the third child to die at an orphanage in eastern Congo during the current outbreak.

"It has been a month after the Ebola outbreak and it is still outpacing our response efforts. There are big gaps in surveillance, diagnosis, contact tracing and community engagement," said Dr. Kerry Dierberg of Doctors Without Borders (MSF), which is helping lead medical response efforts in Congo, the Indian Express reported.

Public health experts warned that the outbreak is spreading faster than health authorities can detect and contain it.

Many infected individuals are not reaching hospitals or health centers and may be dying without being identified as Ebola cases. As a result, health workers are struggling to determine the true scale of transmission, increasing the risk of further spread within the region, NPR reported.
