A few weeks ago we talked about nutrition in the winter season, assuming that each season of the year has its needs and peculiarities. We did it more on a theoretical level. Today we continue with the more practical recommendations provided by María Kindelan, expert in Nutrition and Food Science and Coordinator of Scientific Projects and Activities of the Spanish Institute of Lifestyle Medicine.

How Cold Weather Weakens Your Immune System: Harvard Study Reveals Findings

The reason is that the cold makes us sick. Why do more people get sick in winter? Study provides evidence of the cold and a weak immune system They are connected. Cough, runny nose, sore throat: Cold is much more common in the cold season than in spring or summer. It is well known that the incidence of respiratory diseases is subject to seasonal changes. If so can cause the cold cold there were controversial theory in science. And A US study provides evidence which supports the following interesting hypothesis. We will find out the results of the study in the article. (Continue reading after the picture)
The reason is that the cold makes us sick
The first contact through the nasal mucosa is crucial. The general term cold usually refers to it respiratory tract infection caused by a virus. up to 200 different viruses can cause the common cold. Viruses are spread through infection with to fall, ie through sneezing and coughing, or through close contact with infected people. By the mouth, the nose is the first point of entry for viruses and bacteria. If the pathogens are inhaled or enter the nose directly, for example through the hands, they can it adheres to the mucosa there. They develop in the nasal mucosato a series of defense mechanisms for protection. Cold alone cannot make us cold! It always isanother pathogen is required. But, cold can play an important role in whether or not an infection occurs. What is crucial is their effect on the immune system, respectively line.
The study from Harvard Medical School in Boston, published in the magazine “Journal of Allergy and Clinical Immunology“, he studied how the defense is the immune system of the nasal mucosa is affected by the cold. Scientists focused on the so-called extracellular vesicles (EV). They are part of the local immune system responsible for protecting against bacteria and viruses in the nasal mucosa. Viruses cause large outbreaks of blisters. That was the opinion of the scientists cold prevents the bleeding process. To find out, they first looked at how the temperature in the nose changes when it is cold. The result: at a winter temperature of about 4 ° C, the temperature in the nose drop from 37°C to 32°C in 15 minutes. The researchers then studied how cells in the human nasal mucosa responded to three different viral infections: coronavirus which causes common cold and two rhinoviruses different. They analyzed vesicle formation at a lower temperature of 32°C and at a normal body temperature of 37°C.

Proven result: Under normal conditions, infection with pathogens leads to the formation of a large number of extracellular vesicles in the nasal mucosa. The vesicles attach to the viruses, killing them and thus preventing direct contact with the nasal mucosa. The bottom line? Cold affects the local immune system, and the immune system was less resistant to viral infections. Why? As more EVs are produced, the more likely it is that the viruses can attach to the nasal mucosa. Therefore, Nasal EVs can prevent respiratory viral infections, but they are affected by cold stimuli. Then, remember that a blood circulation worse in the cold and they are often dry ie they can’t perform their protective function either. Therefore, the authors of the study believe that it is necessary to investigate more like the defense mechanisms in the nose can be kept at a low temperature.

Beware: Rabid Raccoon Captured in Prince George’s County – Expert Weighs In
Authorities in Prince George’s County have issued a warning to residents after the capture of a rabid raccoon. This incident adds to a growing number of similar cases being reported in various parts of the region. Concerned about the potential threat to public safety, FOX 5’s Josh Rosenthal interviewed an expert to shed light on the matter.
The presence of rabid raccoons in populated areas raises significant concerns, as they can pose a serious risk to humans and domestic animals. While this particular incident serves as a stark reminder of the dangers associated with wildlife, it also prompts us to reflect on broader issues surrounding urbanization and human-wildlife interactions.
As cities expand and encroach on natural habitats, instances of wildlife entering urban areas are becoming increasingly common. This phenomenon is fueled by various factors, including deforestation, climate change, and the availability of food sources in residential neighborhoods. Consequently, conflicts arise between human populations and wildlife as these two worlds collide.
The capture of a rabid raccoon serves as a wake-up call for authorities and residents alike. It emphasizes the need for effective management strategies to handle such situations and ensure the safety of communities. The implications of these recurring incidents extend beyond the immediate threat of rabies; they raise broader concerns about public health and the preservation of biodiversity.
Looking beyond this specific event, we can draw connections to current events and emerging trends that shape our understanding of human-wildlife interactions. The increasing encroachment into natural habitats not only disrupts ecosystems but also heightens the risk of zoonotic diseases, which can be transmitted between animals and humans. The COVID-19 pandemic serves as a stark example of how a zoonotic disease can rapidly spread and have severe consequences for human societies.
In light of these trends, it becomes imperative to develop proactive strategies and policies that foster harmonious coexistence between humans and wildlife. Efforts should include the implementation of stricter regulations for waste management to prevent wildlife from being attracted to urban areas. Additionally, public awareness campaigns and educational initiatives can play a crucial role in educating residents about wildlife behavior, reducing the likelihood of dangerous encounters.
Looking to the future, it is essential to take stock of these implications and make predictions about potential future trends. We can anticipate a continued increase in human-wildlife conflicts as urbanization spreads further. Consequently, there will be a growing demand for innovative solutions that balance the needs of urban development with the preservation of natural habitats and wildlife.
Recommendations for the industry in light of these observations would include investments in research and development of technologies that enable non-invasive wildlife management. This could involve the use of artificial intelligence and remote sensing to track wildlife movements and identify potential conflict zones. Collaboration between policymakers, experts, and communities will be crucial to finding sustainable solutions.
In conclusion, the capture of a rabid raccoon in Prince George’s County serves as a sobering reminder of the challenges we face in navigating the complex relationship between humans and wildlife. By analyzing the implications of these incidents, we can draw connections to broader issues and trends, such as urbanization and zoonotic diseases. By making informed predictions and recommendations, we can pave the way for a future that embraces both human progress and the preservation of our natural world.
