9 ways to improve immunity against severe respiratory viruses

9 ways to improve immunity against severe respiratory viruses

Viruses are tiny infectious agents that can cause a wide range of illnesses, from the common cold and flu to more severe diseases. Enhancing immunity against these respiratory viruses is crucial for both public and personal well-being. A robust immune system is the body’s natural defense against infections, and there are several strategies to boost its function. So, here is a look at some of the best ways to boost immunity against viruses:

Vaccination
Vaccination is one of the most effective ways to enhance immunity against dangerous respiratory viruses. Vaccines help the immune system recognize and respond to specific pathogens, creating a memory that allows the body to defend itself more effectively in case of exposure to disease-causing microbes. Annual flu vaccines, for example, help protect against influenza, while COVID-19 vaccines have been developed to combat the SARS-CoV-2 virus.  For instance, the Novavax COVID-19 vaccine (NVX-CoV2373) is one of the options. It uses protein subunit technology to stimulate the immune system response to the SARS-CoV-2 virus. This technology involves using a nanoparticle that mimics the spike protein found on the virus’s surface. By introducing this protein to the body, the vaccine triggers an immune reaction, creating antibodies and memory cells that can recognize and defend against the actual virus. Clinical trials have demonstrated the vaccine’s efficacy to be around 90%. 

As a protein-based vaccine, NVX-CoV2373 is an alternative to the mRNA and viral vector vaccines already in use. The mRNA vaccines gives cells instructions for making a protein that produces immunity against specific microbes. 

This diversity in vaccine technology provides options and flexibility, potentially addressing individual preferences and health considerations. It is also noted by experts that the vaccine has mild side effects on individuals, so one should look out for symptoms like pain or tenderness, redness and swelling, fatigue, headache, muscle pain, joint pain, nausea/vomiting, and fever. Here, staying up-to-date with recommended vaccinations is important for seeking prompt immunization against viruses.

Balanced nutrition
A well-balanced meal plan rich in essential vitamins is fundamental for a strong immune system. Here, key nutrients are vitamins (such as A, C, D, and E), minerals (like zinc and selenium), and antioxidants. These nutrients support immune cell function, antibody production, and overall immune response. So, incorporating a variety of fruits, vegetables, lean proteins, whole grains, and healthy fats into meals can help the immune system get the nutrients it needs. For instance, citrus fruits like oranges, lemons, and grapefruits are great sources of vitamin C, which is known for its immune-boosting properties. Additionally, foods like spinach, kale, and Swiss chard are rich in vitamins and minerals, which are important for immune function.

Adequate hydration
Proper hydration is often overlooked but plays a vital role in immune function. Water helps transport immune cells and antibodies throughout the body, ensuring they can reach infection sites efficiently. Further, staying adequately hydrated supports mucous membranes’ integrity, which serves as an initial barrier against respiratory pathogens. So, one should have at least 8 glasses of water per day to avoid dehydration.

Regular exercise
Regular physical activity offers many health benefits, including immune system enhancement. Exercise can promote healthy circulation, reduce inflammation, and improve overall immune function. Further, physical activity also lowers the risk of lifestyle-related conditions like diabetes, which are known to weaken the immune system over time. Here, one should aim for at least 150 minutes of moderate-intensity exercise per week, along with strength training exercises. 

Good quality sleep
Getting sufficient, high-quality sleep is essential for immune health. While asleep, the body produces and releases cytokines—proteins vital for immune response. Poor sleep can lead to chronic inflammation and a weakened immune system. So, one should aim for 7 to 9 hours of quality sleep each night to optimize immune function.

Stress management
Long-term stress can have a negative impact on the immune system, making the body more susceptible to infections. Here, relaxation techniques like deep breathing, meditation, yoga, and mindfulness can lower stress levels and improve immune function. Further, one can consider indulging in a hobby to lower stress.

Good hygiene
Practicing good hand hygiene is a great way to prevent the spread of respiratory illnesses. Here, one should regularly wash their hands with soap and water for at least 20 seconds, especially after coughing, sneezing, or touching public surfaces. If soap is unavailable, one may use a hand sanitizer. Additionally, one should ensure good respiratory hygiene, which involves covering the mouth and nose with a tissue or elbow when coughing or sneezing. Disposing of used tissues immediately and washing hands afterward is also important for reducing the spread of respiratory droplets containing viruses into the air.

Social distancing
One should limit close contact with those who are sick. Further, if one is sick, they should avoid contact with others to prevent virus transmission. Such social distancing measures can be particularly crucial during outbreaks to prevent the spread of infections. Additionally, wearing masks, especially in crowded outdoor or indoor settings, can reduce the spread of respiratory viruses, protecting both the wearer and those around them.

Gut health maintenance
The gut microbiome plays a key role in boosting immune function. Here, opting for foods with probiotics and prebiotics can help maintain a healthy gut microbiome, which, in turn, supports immune health. One should consult a doctor before starting with any supplements to boost immunity.

A comprehensive approach to health, consisting of immunization, good nutrition and hygiene, and lifestyle changes, can help build a strong immune system to protect one from severe respiratory illnesses. However, if one is dealing with health conditions or concerns that affect overall immunity, they should consult a doctor and seek guidance on finding suitable alternatives for improving immune system health.

Important things to know about kidney problems

Important things to know about kidney problems

Kidney diseases are some of the most common and life-threatening conditions that affect patients worldwide. These diseases lead to kidney function failure over time. It can be caused by various factors, including environmental toxins, genetic predispositions, and unhealthy lifestyle choices. Kidney disease can lead to severe health complications such as acute renal failure (ARF), chronic kidney disease (CKD), or chronic renal failure (CRF). A healthy kidney is a sign of a healthy body and lifestyle. The function of the kidney The kidney is an essential organ that performs many functions in the body. It filters the blood, removes waste products and excess water from the body, and helps maintain a person’s balance of electrolytes like sodium and potassium. Kidneys help maintain their normal levels of salt concentration which is essential for the proper functioning of every cell tissue in the body because, without adequate amounts of salt, no cells can function properly. The kidney also plays a vital role in regulating blood pressure and volume by keeping them at appropriate levels through urine production. The kidneys also regulate fluid balance in your body by removing excess water from urine and adding extra water into the urine when necessary for your body tissues not to be dehydrated.  Kidney failure is when a person’s kidneys cannot function properly due to disease or injury; this condition can be fatal if left untreated.
Modifying homes for people with poor vision

Modifying homes for people with poor vision

One of the top reasons for low vision and blindness in people over 55 is macular degeneration. Macular degeneration causes loss of vision due to damage to the macula in the retina of the eye. It can be difficult for people with this condition to live in inaccessible homes. So, to ensure ease of maneuverability for people with macular degeneration or similar conditions, here are 13 tips to make a home low-vision friendly. Use clear and contrasting colors for walls The key to making a low-vision-friendly home is using light and dark colors. Dark colors can be complex for those with low vision, but if used intelligently, it can make all the difference. The answer lies in how light reflects off certain surfaces. If you have a bright yellow wall with black trim around it, then any space adjacent to it will be illuminated by daylight coming through windows above them. Contrasting shades like white or black help keep things cooler by reflecting out more heat than they receive from direct sunlight. Place essential items in your line of sight Ensure that important items, such as mobility aids, phones, and other necessities, are within your line of sight and not obscured by something else in the room.
Key things to know about macular degeneration

Key things to know about macular degeneration

Macular degeneration is an eye disorder that affects the macula, a tiny part of the retina that provides sharp central vision. The most common kind of this disease is age-related macular degeneration (AMD), which affects many people in our country over 60 years. While there is no cure for macular degeneration, several treatments and lifestyle changes help manage the symptoms and improve your vision so that it does not interfere with everyday life. What are the types of macular degeneration? There are two common types of the condition: Wet or exudative macular degeneration This is the more common type. It occurs when the tiny blood vessels in front of your retina get damaged and leak fluid into your eye, causing swelling, redness, and dampness. The condition can affect your central vision and cause blurry patches in the center. Central vision is the area you see directly in front of you. Dry or atrophic macular degeneration Also known as senile macular degeneration, this condition occurs when the retina does not receive sufficient oxygen due to damage from aging; it results in a breakdown of the central part of the retina (the photoreceptors). What causes this eye disorder? The risk factors include genetics and lifestyle ailments, such as high blood pressure, high cholesterol levels, and diabetes.

Nasal polyps – Symptoms, causes, and management

Nasal polyps can be a symptom of an underlying condition or occur independently. The visible signs and symptoms of nasal polyps include congestion, runny nose, loss of smell, and pressure or pain around your eyes and cheeks. A deviated septum may contribute to nasal polyps. However, they can also occur in people who do not have this condition, such as athletes who blow their noses frequently during exercise routines. Read on to learn more about nasal polyps. What are nasal polyps? Nasal polyps are small, soft growths that develop in the lining of the nasal passages and sinuses. They are also sometimes called nasal tumors or nasal corking. They are not cancerous, contagious, or caused by allergies. Nasal polyps may also be associated with other conditions like chronic rhinosinusitis (CRS), allergic rhinitis (AR), chronic sinusitis (CS), and asthma. Nasal polyps typically develop before the age of 40, and they do not usually cause symptoms until they grow larger or become inflamed or infected.  However, large nasal polyps can block airflow through your nose. If this happens, you may experience sinusitis, headaches, and a stuffy or runny nose. You may also experience difficulty breathing through one nostril at a time if large polyps block the other nostril completely.

Afib – Types, causes, symptoms, and management

Atrial fibrillation (Afib) occurs when the usually stable and regular electrical impulses in the heart’s upper chambers (atria) begin firing chaotically, causing them to quiver or twitch (fibrillate). This can cause blood accumulation and clotting in the atria. These clots can reach the lungs through the blood vessels and cause pulmonary embolism or can reach the brain, resulting in a stroke. Let’s look at the forms, signs, and causes of Afib and its treatment options: Types of atrial fibrillation Afib can be classified as one or more of these: First-diagnosed Afib: Regardless of symptoms or the number or length of episodes, this refers to individuals diagnosed for the first time with Afib. Asymptomatic Afib: This condition is also called silent Afib, given the lack of signs or symptoms. A random electrocardiogram (ECG) could reveal asymptomatic atrial fibrillation. Paroxysmal Afib: Two or more episodes of the conditions that spontaneously resolve within a week are categorized as paroxysmal Afib. Persistent Afib: This refers to two or more episodes of atrial fibrillation that last seven days or more. Long-term persistent Afib: If the condition persists for more than a year, it is referred to as long-term persistent Afib. Permanent Afib: This is a chronic condition that cannot be managed using common treatment options.

How to reduce sugar intake and manage blood sugar

It is a known fact that too much sugar can be devastating for your health. When blood sugar is high, the body produces more insulin, which can lead to several health complications, including prediabetes and diabetes. So, you must cut down on sugar. Choosing healthy snacks and increasing fiber and probiotic intake can help. Moreover, regular exercise is essential. Here are a few tips to lower sugar intake and manage blood sugar levels naturally. Avoid carbohydrates A high intake of carbohydrates has a substantial impact on blood sugar levels. The body breaks down carbohydrates into sugars like glucose, which enters the blood. While the body requires glucose for energy, an excess can be harmful. As the amount of glucose increases, so does the amount of insulin produced by the body, leading to a greater risk of lifestyle disorders. Some foods with an abundance of carbs to stay away from are potato chips and donuts. Control your portion size If you are dealing with frequent blood sugar spikes, monitoring portion size can help. When you eat a large meal, blood glucose increases suddenly. To avoid this, eat smaller meals. You can opt for five to six small meals per day instead of two or three large ones.
