Simple Ways to Avoid Painful Wasp Stings - Jordan News
In an interview with The Conversation, Professor Seirian Sumner, a behavioral ecology expert at University College London, said: اضافة اعلان 'There are many simple ways to avoid wasp stings during outdoor picnics, one of the easiest being to place some food on a dish away from where you're sitting. This way, the insects will be attracted to the food and stay away from you.' She added: 'When some people try to protect themselves from an approaching wasp, they panic, run away, or make sudden movements like waving their arms or screaming. These are the wrong reactions — the wasp may perceive you as a predator and attack in self-defense. It's better to stay still and try to keep your mouth closed to reduce the release of carbon dioxide, which may attract these insects.'
The scientist explained that female yellowjackets and German wasps (Vespula germanica) often approach gatherings of people during outdoor activities in search of food for their larvae. They can be diverted by placing a plate with food somewhere else. She added that these females look for meat and protein sources when their larvae in the nest are hungry and need feeding, while they are attracted to sugary substances when they only need energy for themselves — that is, when they are feeding personally.

Simple Ways to Avoid Painful Wasp Stings - Jordan News
Some people get stung by wasps while spending time in nature, which can cause severe pain and, in some cases, serious allergic reactions.

A Child's Obesity Is More Closely Linked to Maternal Genes Than Paternal Ones, Study Finds - Jordan News
A new study has found that a child's risk of obesity may be more strongly influenced by maternal genes than paternal ones, due to a phenomenon known as "genetic nurturing." This emerging concept in genetics refers to the indirect effect of parental genes on a child's health and behavior, not through inherited DNA, but through the environment shaped by parental genetic traits. اضافة اعلان According to this theory, a parent's genetic makeup may influence factors such as education level or lifestyle choices, which in turn shape the environment in which the child is raised—affecting the child's physical and psychological development. This phenomenon is sometimes called "genetics through environment", as it goes beyond traditional genetic inheritance to include the imprint that parental genes leave on daily life and parenting styles. The Study and Its Findings The study, conducted by researchers at University College London (UCL) and published in the journal PLOS Genetics, analyzed health and genetic data from 2,621 British families who are part of the Millennium Cohort Study, which tracks individuals born in the early 2000s. Researchers examined the relationship between the body mass index (BMI) of parents and their children's weight and eating habits across six age stages, from age 3 to 17. They also used self-reported dietary data from the children to assess how both maternal and paternal genetics influenced their physical health. The study found that the father's genetic influence on the child's weight was almost entirely direct, through inherited DNA. In contrast, maternal genetics showed both direct and indirect effects. Even when the researchers controlled for inherited genes, the maternal environment still played a significant role in determining a child's likelihood of being overweight. A Key Role for Mothers' Environments Lead author Liam Wright, a researcher at UCL's Institute of Social Research, emphasized that the findings highlight the critical role of maternal environments, which are shaped by maternal genetics. 'This is not about blaming mothers,' Wright stated. 'It's about recognizing the importance of supporting families to create healthy environments that contribute to better long-term outcomes for children.' The study also went beyond traditional BMI measurements, particularly in children, by including detailed fat mass assessments, offering a more comprehensive picture of childhood obesity. Implications for Public Health Policy The researchers recommend that public health interventions focus on supporting mothers, especially during pregnancy, to help interrupt the intergenerational cycle of obesity. This represents a shift in understanding obesity as a multi-factorial issue, involving genetic, environmental, and behavioral components, and calls for more inclusive, family-oriented support systems—particularly for mothers. On a global level, childhood obesity remains a major concern. According to World Health Organization (WHO) data, 35 million children under age 5 were overweight in 2024. In 2022, more than 390 million children and adolescents aged 5–19 were classified as overweight, including 160 million with obesity. The WHO uses a growth reference standard to diagnose obesity or undernutrition in children, which includes measures like height-for-age, weight-for-age, and BMI-for-age. Studies like this one provide valuable evidence for preventive health strategies worldwide.

Allergies: When the Immune System Becomes a Source of Discomfort - Jordan News
Allergies are among the most common and bothersome health conditions. Their triggers surround us everywhere—from dust and perfumes to food and air. But what exactly are allergies? Why do some people develop them while others don't? How can we distinguish them from the common cold? And is it possible to prevent them or even achieve full recovery through immunotherapy? اضافة اعلان To answer these questions and more, we spoke with Dr. Nour Joradatli, Consultant in ENT and Allergy at Sheikh Shakhbout Medical City, and a German board-certified allergist with over 16 years of experience in the field. What Are Allergies? Dr. Nour explains: 'Allergies are abnormal immune reactions to certain substances in the environment—substances that are typically harmless to most people, such as dust, pollen, animal dander, certain foods, or medications.' She adds: 'When someone with allergies is exposed to these substances, their body produces antibodies called IgE, which bind to specific cells in the nose, skin, or lungs. This process leads to the release of chemicals like histamine, which causes allergy symptoms such as sneezing, runny nose, coughing, skin eczema, or even shortness of breath.' Types of Allergies: Perennial vs. Seasonal When asked about the different types of allergies and how to manage them, Dr. Nour explains that allergies are mainly classified into two types: perennial (chronic) and seasonal allergies. Perennial allergies last year-round and are usually caused by indoor allergens like dust mites, pet dander, and mold. Common symptoms include nasal congestion, chronic coughing, and skin eczema. To manage them, she advises: Washing bedding weekly in hot water (60–90°C) Using anti-allergy protective covers Maintaining indoor humidity below 50% Avoiding carpets and heavy curtains Seasonal allergies occur during specific times of the year, usually triggered by pollen from trees or grasses. Symptoms—like sneezing, runny nose, and itchy eyes or nose—often appear in spring and fall and may sometimes lead to breathing difficulties. Dr. Nour emphasizes early preventive treatment for seasonal allergies. Patients should not wait for symptoms to appear. She recommends starting nasal or chest sprays and antihistamines at least two weeks before allergy season to reduce severity and avoid emergency situations. She also warns against outdoor activities in the fall—particularly in the wild—due to exposure to plant pollens like ranth. She suggests: Wearing masks (even standard medical ones) Keeping car windows closed in rural or desert areas She stresses the importance of strict adherence to treatment plans, advising patients not to stop medication even if symptoms improve. Seasonal allergies can last for weeks, and interrupting treatment can lead to symptom recurrence. To minimize symptoms, she also recommends: Keeping the home clean Washing the face, eyes, and nose after being outside Regularly cleaning air conditioning and purifier filters Can Allergies Be Accurately Diagnosed? 'Yes, diagnosis is key,' says Dr. Nour. Many people treat allergy symptoms as if they were common colds, which delays proper treatment. Diagnosis involves: Taking a detailed medical history Skin prick testing with small amounts of allergens Advanced blood tests to measure IgE levels and reaction severity Treatment: Medication, Prevention, and Immunotherapy Dr. Nour explains that allergy treatment involves several approaches: Avoiding allergens as much as possible Using appropriate medications Allergen immunotherapy, which she describes as a breakthrough in allergy treatment Immunotherapy can be administered either sublingually (under the tongue) or via subcutaneous injections. The goal is to 'train' the immune system to tolerate the allergen without triggering a reaction. It involves giving carefully measured doses over 3 to 5 years, leading to gradual immune acceptance. Dr. Nour notes that this method has shown high effectiveness and is considered the closest thing to a 'cure' for allergies—especially for unavoidable triggers like pollen or dust. Side effects are usually mild (sneezing, itching), but rare cases of anaphylaxis may occur, which is why it's done under medical supervision. Other commonly used medications include: Antihistamines, effective for reducing sneezing, itching, and runny nose. Some older types may cause drowsiness, so they're better taken at night. Inhalers and bronchodilators like Salbutamol, which may cause slight tremors or increased heart rate with overuse Corticosteroids (sprays or topical), which are safe when used as inhalers because they don't enter the bloodstream in large amounts—unlike the high-dose oral or injected steroids used in the past She adds that modern medical awareness has helped dispel myths about corticosteroids, and that correct usage brings major benefits with minimal risks. A Message of Awareness Dr. Nour concludes with a strong message: 'Public awareness and early treatment can completely change an allergy patient's life. Allergies don't have to be a barrier to living a normal, active life. With accurate diagnosis and the right treatment, allergies can be managed, allowing patients to enjoy a safe and comfortable life.' 5 Key Questions… Answered 1. Can allergies suddenly develop in adulthood? Yes. Allergies can develop at any age, even in adults with no prior history. This may result from environmental changes, frequent allergen exposure, or immune system shifts. 2. Is there a link between psychological stress and allergies? Stress doesn't directly cause allergies, but it can worsen symptoms by weakening the immune system and increasing the release of chemicals that trigger allergic reactions. 3. Can allergies affect sleep quality? Absolutely. Nasal and respiratory allergies can cause congestion, nighttime coughing, or shortness of breath, leading to insomnia or disrupted sleep. Regular symptom management greatly improves sleep quality. 4. What's the difference between a food allergy and food intolerance? A food allergy is a sudden and severe immune reaction that can be life-threatening. Food intolerance is a digestive issue that doesn't involve the immune system, and symptoms are usually milder and gradual. 5. Are there natural or alternative treatments that relieve allergy symptoms? Some people use natural remedies like local honey or herbal steam inhalation and opt for natural air filters and fragrance-free cleaners. However, it's essential to consult a doctor first, especially for severe allergies.
