Although the heat can be challenging, there is no legally mandated maximum temperature for workplaces.
This means that employees are generally still expected to report to work.
However, the UK’s Health and Safety Executive (HSE) emphasizes that employers are responsible for protecting workers from health risks associated with high temperatures.
The authority recommends measures such as providing access to drinking water, ensuring good ventilation, and allowing more frequent breaks, according to The i Paper.
Schools remain open
Authorities believe that students can normally continue their education as long as schools take appropriate precautions.
Schools are encouraged to ensure good ventilation, provide students with greater access to water, and relax school uniform requirements where applicable.
Debate about the future
Several organizations believe that temperature limits should be introduced in classrooms.
At the same time, experts point out that hot summers may become more common in the future.
For now, however, the situation remains the same for both students and employees: there is no maximum temperature that automatically entitles schools to close or workers to take time off.
Many people are living longer than previous generations did, but researchers are also trying to understand why some individuals remain healthy well into old age.
In this context, researchers behind the Leiden Longevity Study analyzed families in the Netherlands where exceptional longevity recurs across multiple generations, according to Medical Daily.
Using genetic analyses, they identified several regions of the genome that occur more frequently in these families than in the general population.
The search for an explanation
The researchers examined 212 sibling groups with a history of exceptional longevity and published their findings in the journal bioRxiv.
The aim was to identify genetic differences that may help protect against disease and age-related health problems.
Previous research from the same project has shown that descendants of these families generally enjoy better health than others of the same age.
The body’s alert system
Much of the researchers’ attention is focused on the body’s immune system.
Here, the cGAS-STING signaling pathway plays an important role. The system helps the body respond to damage, but it can also contribute to chronic inflammation, which is associated with aging.
Several pharmaceutical companies are already developing treatments that target this mechanism.
The surprising discovery
The researchers eventually identified a rare genetic variant in the CGAS gene. The variant was found in only two of the families studied.
According to the research findings, the variant reduces the activity of the cGAS-STING system.
This leads to lower levels of inflammation and slower cellular aging.
The results were confirmed through laboratory experiments involving both human and mouse cells.
The researchers therefore believe that this rare genetic variant may be part of the explanation for why some families not only live longer but also maintain better health throughout their lives.
As temperatures rise during the summer, many people choose to leave their windows slightly open throughout the night to let fresh air into their homes.
However, according to Bien, as cited by Dagens.dk, this habit may be less effective than many people believe.
Although the cool evening air can feel refreshing, keeping a window open all night can, in some cases, lead to increased humidity indoors.
This can affect comfort levels and make the indoor environment less pleasant.
An alternative
One alternative is to ventilate the home thoroughly for a short period after sunset.
At this time, outdoor temperatures have often dropped, allowing the warm air that has built up inside during the day to be replaced with cooler air.
By closing the windows again after airing out the home, it may be possible to maintain the lower temperature for a longer period during the night.
Other helpful solutions
Fans can be a useful addition on hot nights because they create air movement, making a room feel cooler.
Some people also place a bowl of ice in front of a fan to achieve an extra cooling effect.
In addition, air purifiers can contribute to a healthier indoor environment by reducing the amount of dust and other particles in the air.
Focus on a good night’s sleep
The choice of bedding can also make a difference.
Materials designed to draw heat away from the body can make it easier to fall asleep on warm nights.
Air conditioning can, of course, be an effective solution, but moderate energy consumption and appropriate settings are important for both financial and environmental reasons.
A combination of targeted ventilation, air circulation, and suitable sleeping conditions may be a more effective strategy than leaving the window open throughout the night.
A medication used to treat hair loss has come under scrutiny following a significant increase in the number of reported side effects.
According to the UK medicines regulator MHRA, cited by The Sun, 547 reports of possible side effects were recorded in 2025. By comparison, the figure was 66 in 2020.
Authorities respond
Finasteride is a common used treatments for hair loss. The drug works by affecting a hormone that plays a role in the development of hair loss, The Sun reports.
In response to the concerns, the MHRA decided in 2024 that finasteride packaging must include a special warning card.
The aim is to make users aware of the known risks associated with the treatment.
Both physical and psychological problems
The reported side effects include skin rashes, acne, nausea, and bad breath.
Cases of depression, anxiety, and panic attacks have also been recorded, according to the MHRA.
The regulator emphasizes that all medicines can have side effects and that the benefits and risks should be assessed together with a doctor.
Other side effects
According to the MHRA, 159 men reported erectile dysfunction, while 67 reported a reduced sex drive.
In addition, cases of testicular pain, enlargement of breast tissue in men, and the rare condition Peyronie’s disease, which can cause curvature of the penis, were recorded.
Most people keep honey in the kitchen without giving it much thought. It is stirred into tea, drizzled over breakfast or used as a simple alternative to sugar. But researchers are increasingly looking beyond its sweetness and examining what else this natural food may offer.
According to research highlighted by Interia Zdrowie and findings from nutrition and cardiovascular studies, honey contains a variety of plant compounds, antioxidants and naturally occurring substances that may support several functions in the body.
Experts stress that honey is not a medicine, but growing evidence suggests it may provide benefits when consumed in moderation.
More than just sugar
Although honey is primarily made up of natural sugars, researchers say its composition is more complex than that of refined sugar.
Studies have explored whether honey may help support healthy metabolic processes and influence blood sugar regulation differently from traditional sweeteners. Scientists have also investigated its potential role in maintaining healthy cholesterol levels and supporting cardiovascular function.
However, experts caution that honey remains a source of sugar and should not be consumed without limits.
A traditional remedy under review
For generations, honey has been used as a home remedy during cold and flu season. Today, researchers are examining whether science can explain its long-standing popularity.
Several studies suggest that honey may help soothe coughs and irritation in the upper respiratory tract. As a result, it is often viewed as a simple and accessible option for relieving mild symptoms.
Growing interest in gut health
Scientists are also exploring honey’s relationship with the gut microbiome. Natural compounds known as polyphenols may help support beneficial bacteria and contribute to a healthier digestive environment.
Researchers have highlighted several potential benefits:
May support gut health
Contains antioxidants
May help soothe coughs and sore throats
Could contribute to heart health
While the findings are promising, experts agree that honey works best as part of a balanced diet rather than as a replacement for medical treatment.
Peanut butter has become a staple in many households and is used in everything from breakfast meals to snacks. While it is calorie-dense, it can also provide several valuable nutrients when enjoyed as part of a balanced diet.

A small serving can be a practical choice on busy days when extra energy is needed between meals.
The simplest varieties contain mainly peanuts and possibly a small amount of salt, while products with numerous added ingredients generally offer a less favorable nutritional profile.
Most people take pride in doing things well. Whether it’s preparing for a meeting, completing a project or organizing daily life, aiming for high standards is often seen as a positive trait.
But psychologists say there can be an overlooked cost when the pursuit of excellence becomes a constant need.
According to psychological research highlighted by Tupi, people with strong perfectionist tendencies often find it harder to adapt when plans change or situations become unpredictable.
What appears to be discipline and ambition on the surface can sometimes create challenges beneath it.
When control becomes a problem
Perfectionism is about more than setting high goals. Researchers describe it as a pattern often linked to a need for certainty, control and flawless outcomes.
Because of this, unexpected changes can feel especially uncomfortable. New routines, shifting priorities or uncertain situations may trigger higher levels of stress and anxiety than they do for others.
Experts say this can make it more difficult to adjust quickly when life does not go according to plan.
Stuck between success and failure
One common characteristic of unhealthy perfectionism is all-or-nothing thinking. Instead of seeing progress on a spectrum, outcomes are often judged as either complete success or total failure.
This mindset can contribute to:
Excessive self-criticism
Delayed decision-making
Procrastination
Increased stress during change
Over time, these patterns may reduce flexibility and make everyday challenges feel more overwhelming.
Building greater flexibility
Psychologists emphasize that perfectionism is not always harmful. High standards can be motivating and help people achieve meaningful goals.
The key difference is flexibility. Research suggests that people who can adapt their expectations, accept mistakes and view setbacks as part of growth are often better equipped to handle change.
Rather than abandoning ambition, experts recommend developing a more balanced approach that allows room for both achievement and adaptation.
Fish oil is one of the most popular dietary supplements among older adults.
Many people use it in the hope of protecting their memory and reducing the risk of diseases such as Alzheimer’s.
Researchers have therefore spent several years investigating whether omega-3 fatty acids from fish oil can help the brain stay healthy for longer.
A two-year study
A new study, published in the journal EBioMedicine, followed 365 people between the ages of 55 and 80 who were at increased risk of developing Alzheimer’s disease.
Participants received either a daily omega-3 supplement or a placebo for two years, according to HealthDay.
Researchers first wanted to determine whether DHA, an important omega-3 fatty acid, actually reached the brain.
Measurements showed that DHA levels increased by around 17 percent after six months.
Testing the brain
The researchers then examined participants’ memory and brain function through cognitive tests and brain scans.
The results showed no measurable benefit for those who took fish oil.
There were no improvements in memory or cognitive abilities compared with the group that received a placebo.
The study also found that the development of brain regions associated with Alzheimer’s disease was not affected.
What does it mean?
Although the omega-3 fatty acids reached the brain, researchers found no evidence that fish oil could protect against Alzheimer’s disease.
The study therefore suggests that fish oil alone is not an effective method of preventing the most common form of dementia.
Instead, the researchers emphasize that regular exercise, good sleep, and a healthy diet remain among the most important factors in reducing the risk of the disease.
Researchers from INSERM and Université Sorbonne Paris Nord followed more than 112,000 French adults for up to eight years as part of the NutriNet-Santé project. The findings were published in the European Heart Journal and cited by Medical Daily.
The study is among the largest of its kind. At the same time, the researchers emphasize that it is an observational study.
Therefore, the results cannot prove that the preservatives directly cause disease.
The researchers examined 58 different preservatives and focused particularly on those consumed by a large proportion of participants.
Focus on food additives
An important aspect of the study concerns the difference between naturally occurring substances in foods and additives used in food production.
According to the researchers, a substance may affect the body differently depending on how it is consumed.
A nutrient found in fruit is not necessarily equivalent to the same substance used as an additive in an industrially manufactured food product.
This is particularly relevant because food manufacturers are increasingly using ingredients of natural origin in their products.
The preservatives
The researchers found that eight common preservatives were associated with a 29 percent higher risk of high blood pressure among individuals with the highest intake compared with those with the lowest intake.
In addition, one additive was linked to a 16 percent higher risk of cardiovascular disease.
Among the preservatives associated with high blood pressure were citric acid and ascorbic acid, which are often marketed as natural ingredients.
Among individuals with the highest intake, these substances were associated with a 22 percent higher risk of high blood pressure.
