Asthma: Causes, Symptoms, and Management

Asthma affects around 25 million individuals in the United States. Though symptoms are manageable, changes in the weather and your daily activities might introduce new triggers, resulting in asthma flare-ups. For example, when the temperature drops during the winter, we spend more time indoors. Understanding how this may influence your asthma is essential to improved management. What is Asthma? Asthma is a long-term, chronic lung illness. It affects your airways, which are the tubes that move air into and out of your lungs. Asthma can cause airways to become irritated and constricted. As a result, it may cause difficulty breathing, coughing, and chest tightness. When these symptoms worsen, the flare-up is known as an asthma attack. Although asthma is a mild annoyance for some people, it can be severe for others, causing disruptions to everyday activities and may result in a life-threatening asthma attack. There is no cure for asthma;

Cleaning the Air VS Ventilation

Air cleaners and HVAC filters, when properly used, can help minimize airborne pollutants such as viruses. Proper filtration must be part of your plan to limit the risk for airborne transmission of viruses, such as COVID-19, illnesses like sick building syndrome, and improving poor indoor air quality. The primary purpose of HVAC filters and air cleaners is to filter pollutants or toxins from the air that travels through them. As a result, air cleaning and ventilation can help minimize airborne pollutants, such as virus-containing particles. In addition, air cleaners can be beneficial when further ventilation with external air is not available without jeopardizing comfort or significant outdoor air pollution. Cleaning the Air Eliminating particles from the air is known as air purification or air cleaning. Particulates include allergies, automobile exhaust, and combustion gasses. Air purification cleans and recirculates the existing air without introducing fresh air into the residence. Unfortunately, it

What Is Sick Building Syndrome?

Sick building syndrome (SBS) is a disorder that is supposed to be caused by being in a building or other confined environment. The cause of this disorder is thought to be poor indoor air quality. However, the actual reason remains uncertain; according to the Consumer Product Safety Commission, approximately 30% of new and remodeled buildings have poor indoor air quality. Identifying SBS is often challenging due to the vast range of symptoms that simulate other ailments, such as the common cold. However, the main feature of SBS is that your symptoms improve once you exit the building in question and return when you reenter the building. Therefore, if you observe recurring symptoms that emerge when you enter a specific building, you may consider looking into sick building syndrome as a possible explanation.  What Causes Sick Building Syndrome? There is no exact explanation for the cause of sick building syndrome.

What is Nanofiber?

Nanofiber is a relatively new and exciting technology that is disrupting industries all around the world! These tiny strands of material are created using various techniques and methods that have been developed over the course of hundreds of years. Around the year 1600, a man named William Gilbert observed how fluid behaved when influenced by an electric field produced by rubbing a piece of amber. When the amber was brought close to the fluid, it created a shape now known as a Taylor cone (see Figure1). After this initial discovery, there were many scientists and academics who saw the potential of future applications. In 1887, British physicist Charles Vernon Boys published a manuscript on the development of nanofiber and how it could be produced in the future. Boys’ findings, along with many others, likely aided American inventor John Francis Cooley in filing the first modern electrospinning patent in 1900.
