Dreams are a natural part of sleep and arise when the brain processes experiences and emotions.
They are often most vivid during REM sleep, when the brain is highly active.
Stress, depression, and poor sleep can make dreams more intense and easier to remember.
During the coronavirus pandemic, many people experienced this, which researchers link to increased mental strain.
The same type of influence is often seen in seriously ill individuals, where both stress and sleep problems play a role.
Recurring patterns
According to a study published in Death Studies and reported by the media outlet Lrytas, based on the experiences of 239 professionals in Italy, many dying patients have similar dreams.
Several describe experiences in which they see deceased family members or move toward symbols such as light, doors, or stairs.
Researchers believe that such dreams may help create calm and understanding in a difficult situation.
At the same time, there are also more unpleasant dreams, which may reflect fear or inner conflicts in patients.
Unresolved answers
Although the patterns recur, the causes are not yet fully understood. Researchers point out that both psychological and cultural factors play a role, but more knowledge is needed.
Many patients do not speak openly about their dreams, making the phenomenon more difficult to study in detail.
These dreams often occur in the final phase of life and may have special significance for the individual.
Brazil nuts have become popular as a nutrient-rich snack with several health benefits.
They contain a range of essential vitamins and minerals that can affect the body in different ways.
Here is an overview of what happens when they become a regular part of your diet, according to EatingWell.
High content of selenium

Researchers from Mass General Brigham and Rush University Medical Center studied 1,338 older individuals over a period of up to 19 years, according to Illustreret Videnskab.
Participants wore a wrist-based activity monitor for 10 days, which recorded their sleep and rest patterns throughout the day.
The results, published in JAMA Network Open, provided precise data on when and for how long participants slept during the daytime.
Timing of naps
The findings revealed clear differences in participants’ sleep patterns.
Individuals who slept longer during the day had higher mortality rates. The same applied to those who took more frequent naps.
In addition, the timing of naps made a notable difference. Morning naps were associated with higher mortality than those taken later in the day.
Link to diseases
The researchers emphasize that the findings do not establish a direct causal relationship, but rather indicate an association.
An increased need for daytime sleep may be linked to conditions such as cardiovascular disease, circadian rhythm disturbances, or neurodegeneration.
It may also reflect more general health issues.
The naps themselves are not necessarily the problem. However, changes in sleep patterns among older adults may serve as an early indicator of illness.
Therefore, such changes could be important to monitor in healthcare and prevention efforts.

Asthma in young children is a common condition, affecting up to one in five. It often presents as coughing, shortness of breath, and recurrent respiratory infections.
Researchers have long suspected that part of the explanation may already be found during pregnancy.
A new study published in Cell Reports Medicine and reported in a press release from Ritzau shows that infants may exhibit differences in their airways early in life.
As early as one month of age, variations in bacteria and immune responses can be measured.
These differences are associated with how often the child develops infections, which in turn may increase the risk of asthma later on.
Not all are affected equally
The study is based on data from several hundred mothers and children who were followed for up to ten years.
Researchers compared blood samples taken during pregnancy with the children’s health outcomes.
The results also show that omega-3 supplements do not have the same effect on everyone.
Some children experience a reduced risk of asthma, while others are not affected.
This suggests that prevention may need to be tailored to the individual rather than applied uniformly.
Fatty acid molecule
Although the researchers cannot yet apply the findings directly in practice, they point to a possible explanation.
A specific fatty acid molecule, known as 12-HETE, appears to play a role.
Children of mothers who did not have this molecule in their blood during pregnancy more often developed asthma and had more respiratory infections.
Conditions during the fetal stage may therefore have significant implications for a child’s health.
In a French Alpine village with only a few hundred residents, 16 people were diagnosed with ALS.
This is an unusually high number for such a small area, reports Göteborgs-Posten.
ALS is a disease that gradually paralyzes the body’s muscles and often leads to death within a few years.
Cause still unknown
Researchers do not yet know exactly why ALS develops. In around 90 percent of cases, there is no clear explanation.
The disease is believed to result from a combination of genetic factors and environmental influences.
For this reason, scientists are also examining whether certain locations or habits may increase the risk.
A toxic mushroom draws attention
A study published in the Journal of the Neurological Sciences in 2021 shows that several of those affected in the village had eaten the false morel mushroom.
The mushroom is toxic and banned in France, but in some parts of the world, such as Sweden, it may be sold if properly prepared.
Nevertheless, authorities advise against consuming it due to health risks.
Researchers believe there may be a link between the mushroom and the disease, but they cannot prove it.
It is likely that several factors interact and that no single cause alone can explain why the disease develops.

A doctor in the United Kingdom offered treatments to cancer patients in exchange for substantial payments, despite no longer holding a valid medical license, People reports.
According to regulatory authorities, patients were charged up to approximately $20,000 for treatment courses that included, among other things, injections of garlic oil and other alternative methods without documented effectiveness.
The case was reviewed by the Medical Practitioners Tribunal Service, which determined that the treatments were carried out without an approved clinical basis and without a valid license to practice.
Critical conditions in the treatment environment
Investigations by health authorities found that the treatments were conducted in a private home, where conditions were assessed as unhygienic and unsuitable for medical care.
Reports described contaminated surfaces, reuse of equipment, and a lack of separation between living space and clinic.
These conditions were highlighted as a significant risk to patient safety, according to the BBC.
Misleading information and lack of evidence
The case also included assessments of whether patients were misled about the effectiveness of the treatments.
Expert testimony indicated that the methods used lacked clinical evidence as cancer treatments.
At the same time, the investigation found that claims of high success rates and criticism of established treatment methods had been made, influencing patients’ decisions.
The doctor was ultimately removed from the UK medical register, as authorities concluded that his actions posed an ongoing risk to the public and constituted serious breaches of professional standards.
Most people consider brain health to be just as important as physical health, but few know how to take concrete steps to protect it.
New research suggests that lifestyle plays a crucial role. Here are key insights and habits from the report, according to NBC News.
The importance of the brain

A major study published in BMJ Oncology and reported by LADbible shows that 11 different types of cancer have become more common among young people ranging from their late teens to their 40s.
These include colorectal cancer, breast cancer, and thyroid cancer.
Colorectal and breast cancers are the most prevalent and account for around 11,500 cases annually among younger adults.
Most of these cancer types are also increasingly seen in older populations.
Known causes do not explain the trend
Researchers have examined whether changes in lifestyle could explain the increase.
Smoking and alcohol consumption have declined, and many people have become more physically active.
Dietary factors, such as the consumption of processed foods or low fiber intake, also do not align with the rise in cancer cases.
This means that the most well-known risk factors do not provide a clear explanation.
Possible explanations under investigation
One factor that mirrors the trend is the rise in overweight and obesity since the 1990s.
Excess weight can affect hormone levels in the body and increase the risk of certain cancers, but researchers believe it does not fully explain the trend.
They are therefore also examining other possible causes, including environmental influences, air pollution, antibiotic use, and changes in gut bacteria.
Researchers are still unable to explain the majority of cancer cases among young people, even though they have now identified some possible associations.
These patients were often younger and less likely to have classic risk factors such as high cholesterol, diabetes, or obesity.
The median age was 52, which is lower than that of other patients, and they used methamphetamine.
At the same time, there were more men than women in this group, although lifestyle factors such as smoking and alcohol use were more prevalent, the study shows.
Different disease progression
Treatment for this group also differed. Fewer required procedures to open blocked blood vessels, suggesting a different type of impact on the heart, according to the researchers.
In addition, more patients were readmitted with new heart attacks. Around 42 percent experienced another heart attack, compared with 27 percent among other patients.
Mortality was also higher in this group, making the findings particularly concerning.
One in six heart attacks
The results point to a shift in who is affected by heart disease. Experts believe that certain factors may significantly accelerate disease development.
Methamphetamine was linked to about 15 percent of all cases, corresponding to one in six heart attacks during the period.

Hair loss is a common side effect of cancer treatment and can be psychologically distressing.
As a result, many patients choose to try various solutions on their own to restore hair growth.
One of the most commonly used supplements is biotin, a vitamin found in everyday foods, and deficiency is rare.
Nevertheless, many people take it as a supplement, often based on advice from the internet or acquaintances.
According to SciTechDaily, this applies to more than half of patients experiencing hair loss.
Issues with tests
Research from Ohio State University, published in JCO Oncology Practice, shows that biotin can affect blood tests.
This includes tests used to monitor the progression of several types of cancer.
Biotin can interfere with measurements, making results misleading. Some values may appear lower than they actually are, while others may appear higher.
This can lead doctors to make decisions based on incorrect information or to delay treatment.
There are also indications that biotin may affect measurements used when heart problems are suspected, making it more difficult to establish an accurate diagnosis.
Better alternatives
Researchers point out that there are safer ways to manage hair loss. One example is the drug minoxidil, which is approved and used to promote hair growth.
At the same time, researchers emphasize the importance of patients consulting their doctor before starting dietary supplements.
This can help prevent complications during treatment.
Biotin not only lacks documented effectiveness against hair loss but may also interfere with critical aspects of cancer treatment.
