Vivid Dreams May Make Sleep Feel Deeper, Study Suggests

Published

on

New research is challenging long-held assumptions about what defines a good night’s sleep, with scientists finding that vivid, immersive dreams may play a key role in how deeply people feel they have rested.

The study, conducted by researchers at IMT School for Advanced Studies Lucca and published in PLOS Biology, suggests that sleep is not simply about how long or how quietly the brain rests. Instead, the nature of mental experiences during sleep may significantly shape how restorative it feels.

For decades, deep sleep has been associated with a largely inactive brain, characterised by slow waves and minimal mental activity. Dreaming, on the other hand, has typically been linked to rapid eye movement (REM) sleep, a stage where brain activity resembles wakefulness. The new findings indicate that this distinction may not fully capture how people experience sleep.

Researchers analysed 196 overnight sleep recordings from 44 healthy adults using high-density electroencephalography (EEG) to track brain activity. Participants were awakened multiple times during non-REM sleep and asked to describe what they had been experiencing and how deeply they felt they had been sleeping.

Across more than 1,000 awakenings, the results showed that people often reported the deepest sleep not only when they had no conscious awareness, but also after experiencing vivid and immersive dreams. By contrast, fragmented or fleeting thoughts were linked to a lighter perception of sleep.

Giulio Bernardi, the study’s senior author, said the findings highlight an important distinction in how mental activity during sleep is perceived. He explained that not all brain activity feels the same to the sleeper, and that the intensity and immersion of dreams appear to influence whether sleep is experienced as deep or shallow.

The study also found an unexpected pattern over the course of the night. As sleep progressed, participants reported feeling that their sleep was becoming deeper, even though biological indicators suggested the body was becoming more rested and sleep pressure was decreasing. Researchers observed that this shift coincided with an increase in the vividness of dreams.

Scientists say this could help explain why some people feel they have slept poorly despite meeting standard measures of sleep quality, such as duration or sleep stages. If dream experiences shape the perception of rest, disruptions in dreaming could affect how refreshed a person feels upon waking.

The findings may influence how sleep quality is assessed in the future. Rather than relying solely on objective measures like brain waves or total sleep time, researchers suggest that subjective experiences, including dream intensity, could become an important factor.

Experts say the research opens the door to new approaches in sleep therapy, where improving the nature of dream experiences might help enhance overall sleep quality and well-being.

EU Split Over Extra Market Protection for Medicines as Biotech Act Talks Intensify

Published

on

EU health ministers remain divided over a proposal to extend market protection for certain innovative medicines, as Brussels seeks to balance industrial competitiveness with patient access and healthcare affordability.

The proposal, part of the wider Biotech Act package, would grant an additional year of exclusivity under Supplementary Protection Certificates for selected treatments. These would apply to medicines containing new active substances, those with different mechanisms of action compared with existing therapies, products tested in more than two EU member states, and drugs with at least one manufacturing step carried out within the bloc.

The European Commission argues the measure is necessary to attract biotech investment, strengthen domestic manufacturing, and prevent pharmaceutical innovation from shifting to other global markets. EU Health Commissioner Olivér Várhelyi defended the proposal, saying that without stronger incentives, many new treatments would not reach Europe until after patent expiry elsewhere.

He also rejected concerns over cost implications, suggesting that greater investment in preventive healthcare could offset long-term spending pressures on national health systems.

However, several member states raised strong objections, warning that longer exclusivity periods could delay the entry of cheaper biosimilar alternatives and increase strain on public healthcare budgets. Critics also questioned whether the proposal sufficiently considers unequal access to medicines across the EU.

Malta highlighted stark disparities in availability, noting that it had access to only 17 innovative medicines approved between 2020 and 2023, compared with more than 150 in Germany and over 140 in Italy. Officials warned that extending monopoly rights could deepen such inequalities.

Estonia echoed these concerns, stressing the need for a balanced approach that considers affordability, accessibility, and the long-term sustainability of national health systems.

Other delegations, including Poland and France, questioned whether the Commission had provided enough evidence to justify the policy shift. Some ministers pointed out that the proposal was not accompanied by a standalone impact assessment and relied instead on broader pharmaceutical sector analysis.

Despite disagreements, there was broad agreement on the need to simplify clinical trial procedures, reduce administrative burdens, and avoid regulatory overlap. Many countries also emphasised the importance of strengthening biosimilar markets, which are seen as critical to lowering drug costs and improving patient access across the EU.

France and several other member states argued that biosimilars play a key role in ensuring system resilience and affordability, particularly for smaller healthcare systems.

The debate reflects a broader fault line in EU industrial policy: how to encourage innovation without undermining access and cost control.

As negotiations continue, attention is shifting to Ireland, which will assume the Council of the EU presidency next. Irish Health Minister Jennifer Carroll MacNeill urged member states to accelerate discussions, citing increasing global competition in biotechnology.

She said the external environment makes rapid progress essential and confirmed that Ireland will prioritise clinical trial reform and measures to strengthen Europe’s biomanufacturing capacity.

MacNeill added that Europe must streamline regulatory frameworks to remain competitive, warning that delays could allow other regions to pull further ahead in biotech innovation.

EU Ministers Back Biotech Rule Overhaul to Boost Innovation and Organ Transplant Cooperation

Published

on

EU health ministers have agreed on a common position to update biotechnology and organ transplantation rules, as the bloc seeks to strengthen its competitiveness in a sector increasingly dominated by the United States and China.

The agreement, reached on 16 June, forms part of the broader Biotech Act package and focuses on revisions to two existing directives covering genetically modified micro-organisms (GMMs) and organ processing procedures. The reforms aim to make regulatory frameworks more flexible, reduce administrative burdens, and improve cross-border cooperation in medical and scientific fields.

Officials say the changes are intended to help Europe catch up in biotechnology innovation, where global rivals have accelerated investment and development in recent years.

Cyprus Health Minister Neophytos Charalambides, who led the negotiations, said the update reflects scientific and technological advances that have taken place since the original rules were introduced. He described the revision as both a practical adjustment and an ethical necessity, given the pace of change in the sector.

Under the revised approach, EU countries agreed to adjust terminology in the European Commission’s proposal. The term “low-risk GMMs” has been replaced with “GMMs eligible for an expedited procedure”, reflecting a more streamlined approval pathway. In addition, consent for placing certain GMMs on the market may now be valid for up to ten years, instead of indefinitely.

The agreement also introduces provisions allowing personal data processing to be treated as serving the public interest in specific cases, particularly where it supports medical or scientific outcomes.

In the area of organ transplantation, member states agreed to extend the implementation period for updated rules from 24 months to 36 months, giving national health systems additional time to adapt to the new requirements.

While the compromise was largely supported, discussions highlighted continuing tensions within the EU over how to balance innovation with safety oversight. Several member states stressed the importance of maintaining strict ethical safeguards, protecting personal data, and preserving national control over transplant systems.

The agreement among member states allows negotiations with the European Parliament to begin once it finalises its position. Lawmakers in the Parliament’s Health (SANT) and Environment (ENVI) committees are currently reviewing the proposal, with MEPs Adam Jarubas of the European People’s Party and Marta Temido of the Socialists and Democrats leading the process.

Charalambides also suggested that upcoming talks should take into account an opinion issued by the European Data Protection Supervisor in late May, noting that it arrived too late to be fully incorporated into the Council’s position.

As Cyprus concludes its presidency of the Council of the EU, responsibility for advancing the file now passes to Ireland, which will guide the next stage of negotiations between member states and the European Parliament.

UNICEF Warns Climate Crisis Is Exposing Nearly All Children to Rising Global Health Threats

Published

on

Nearly every child in the world is now exposed to at least one climate-related hazard, with many facing multiple overlapping risks that threaten their health, education and long-term development, according to a new UNICEF report.

The findings highlight how intensifying climate change is reshaping childhood on a global scale, as heatwaves, floods, droughts and wildfires become more frequent and severe. UNICEF Executive Director Catherine Russell said children are already experiencing the consequences in their daily lives.

“The lives of children continue to be upended by the impact of heatwaves, wildfires, droughts and floods,” she said, noting that around half of the world’s children now live amid at least three overlapping climate threats.

The report warns that while the physical and mental toll on children is significant, it remains under-measured in global assessments. It also calls for stronger investment in health, education and infrastructure systems designed specifically to withstand climate shocks and protect younger populations.

UNICEF said children are disproportionately affected because their bodies are still developing, making them more vulnerable to heat stress, pollution and disease. Although these biological factors cannot be changed, the agency stressed that governments can reduce risks by strengthening essential services and infrastructure.

The report outlines how climate hazards often trigger cascading crises. Droughts can destroy crops and worsen food insecurity, while also leaving dry vegetation that fuels wildfires. These fires increase air pollution and can be followed by floods, which damage land and increase the spread of waterborne diseases.

Flooding remains one of the most widespread threats, with more than 360 million children globally exposed. UNICEF warns floods can cause drowning, injury and outbreaks of diseases such as cholera and malaria. Damaged housing also increases the risk of mould exposure, contributing to respiratory illness.

Extreme heat is another major concern. More than 1.5 billion children are exposed to frequent heatwaves, which can lead to heat stress and long-term health complications. Pregnant women are also at increased risk of complications, including preterm birth and high blood pressure disorders.

Air pollution remains a nearly universal risk, with about 2.3 billion children living in areas with unsafe air quality. Because their lungs and immune systems are still developing, children are particularly sensitive to long-term damage caused by polluted air.

The report also highlights the growing spread of vector-borne diseases. Around 1 billion children are now at risk of malaria, alongside increasing exposure to dengue and other infections linked to changing climate conditions.

UNICEF says these combined threats are not only a health crisis but also a major barrier to education and development, warning that urgent action is needed to build resilience and protect future generations.
