VIRAL INFECTIONS AND IMMUNITY

The throat, nose, and lungs are the primary sites for viral infection of the respiratory system. In humans, these organs are lined with a special type of tissue called epithelium that acts as a sponge, trapping fluids and toxins before they can enter the bloodstream. When we sneeze or cough, some of this fluid comes through our airways, but most of it is trapped in our small skin pores by mucus, which forms at the end of the nose and mouth. It is usually clear to the naked eye, but if you have an allergy or cold, there is often more trouble with the upper respiratory tract.

When the mucus becomes blocked or filled with water, it is hard enough to collect on the ground for 15 minutes and then stick or float around. This floating debris can become airborne when exhaled in the form of droplets (smaller than a pinhead) that linger in the air and sometimes float above the surface of the skin. Droplet nuclei travel at less than one millimeter per second, with the diameter ranging from 1-3 microns. Sometimes it may be difficult to tell what has been expelled from the person's nostrils, so we call this "nose splashing." A single drop of saliva is tiny in comparison with a large amount of mucous that falls on the tongue after breathing. Even though saliva is not a liquid, it contains enzymes that break down lipids and proteins and cause acid mucus to be formed. Acid mucus also attracts microbes from other parts of the body into the upper respiratory tract. Some people with asthma are sensitive to certain types of bacteria and fungi in their homes or the environment they live in because such organisms can attach themselves to epithelial cells as allergens. These allergies are known as allergic rhinitis.

If your symptoms develop suddenly and do not respond to treatment within several days, a doctor will likely suggest your symptoms are related to allergies. For example, someone might be experiencing nasal congestion that seems to have nothing to do with colds or flu. However, if you have an allergic reaction to pollen, mold spores, grasses, weeds, mold, dust mites, and other fungal irritants, you are dealing with a sinus infection related to allergies. The most common causes of sinus infections include allergens, viruses, parasites, bacteria, and fungi. Many people who suffer from allergies suffer from recurrent sinusitis and runny nose. Sinusitis is common for children around four years old, and it is treated just like other common cold and flu symptoms. If you experience any discomfort while sleeping, however, consult your doctor immediately. While the exact nature of sinusitis is unknown, it is believed that inflammation has caused the condition to occur. Sore throats and headaches are the first symptoms of sinusitis, followed by redness around the eyes, nasal discharge, a fever, and headache. Treatment should focus on relieving pain, maintaining regular airflow to enhance drainage, and allowing room for the flow of air as much as possible to relieve congestion. Patients should also drink plenty of liquids and limit their intake of caffeine and strong foods. A general recommendation is to avoid smoking while improving overall health.

It's hard to understand why certain patients have trouble breathing during severe coughing fits or colds, although these disorders do cause problems around the face, chest, abdomen, stomach, and lower back, although they can appear anywhere. There are many reasons why a patient may feel short of breath. Sometimes a patient experiences symptoms that mimic other conditions, such as pneumonia or influenza. But other times, these symptoms can be completely unrelated to a specific illness. Whatever the case, it is incredibly important to get the right diagnosis if you suspect that the problems could be due to something more serious. Here, Dr. Pops recommends seven things you can do to strengthen your immune system.

1. Get Enough Exercise. Exercise releases hormones that help maintain a healthy immune system and keep cells alive. Regular exercise can also help reduce the frequency of colds and flu. Although exercising helps improve your physical health, don't neglect taking care of your mental well-being. Don't let the stress of everyday life get in the way of finding time to stay mentally and emotionally balanced. One study found that individuals who exercised regularly were 28 percent less likely to suffer from depression over three years. Find the activity that works for you, whether that means going jogging, working on an indoor rock climbing wall, or lifting weights. Remember, no matter how great your workout is, you need to take breaks throughout the day to rest!

2. Try a Healthy Diet. Your diet has many influences on your immune system. Avoid processed foods to ensure your body gets all the essential vitamins and minerals to remain healthy and fight diseases. Limit sugary beverages and artificial sweeteners to help regulate sugar as part of the digestive process. Make sure you get good amounts of omega-3 fatty acids, vitamin C, magnesium, calcium, iron, zinc, potassium, iodine, folate, and vitamin D. Eating a variety of fruits, vegetables, legumes, nuts, fish, and eggs have all been shown to benefit the immune system. Meat, seafood, poultry, beans, and grains contain high levels of essential nutrients that help boost immunity. Also keep these foods away from children and pregnant women, as these nutrients may impact birth weight, giving them poor digestion. Consider choosing whole foods instead of processed foods. Choose low-fat meat instead of deli meats or chicken, and choose fresh, frozen, canned, or dried fruit instead of packaged ones. To protect yourself against various bugs and infectious diseases, try using a quality reusable water bottle every time you're out in public and avoid sharing personal items with others. Use paper napkins and plastic cups whenever possible, as well. Wash hands frequently and regularly and washes frequently touched utensils after each use. Keep tissues readily available to use in case of an emergency.

3. Stay Hydrated. Water is the key ingredient of your immune system. It helps move waste, carries oxygen around the body, regulates the internal temperature, removes toxic materials and pathogens from your body, produces enzymes, provides hydration, maintains a stable pH balance, nourishes your brain and nervous system, and replenishes your body. Drink plenty of water throughout the day and especially during sickness. You should aim to drink between eight and ten glasses each day. If you have difficulty holding down a full glass, consider adding electrolytes to add flavor and texture to the taste, including sports drinks. You may be surprised how quickly the benefits of hydration kick in once you increase your consumption. Drinking lots of water also promotes better concentration and improved memory performance. Staying well hydrated is vital to prevent dehydration-related illnesses.

4. Be Healthy at All Times. Sickness and illness are natural occurrences that can happen to anyone. Living a disease-free lifestyle can take a toll on both your physical and emotional well-being. People with medical conditions such as high blood pressure or heart disease should try to manage both in the short term. For those without a chronic medical problem, living as a normal healthy person in the long term can greatly benefit your well-being. Eat regularly and avoid excessive caffeine, smoking, and harsh alcohol. Sleep sufficient hours. Stress may lead to sleepiness and make us wake up too early. Excessive daytime naps can leave our bodies exhausted instead of energized. Go to bed and rise at about the same time each day, with no delays or disruptions. Take frequent walks and walk in the place, even if you've recently moved. And always pay attention, and watch out for signs of fatigue or anxiety. Relaxation techniques such as meditation should be considered in addition to medications and other non-medical treatments. Practicing relaxation exercises after meals also prevents mindless eating, which may contribute to food intake being too close together over time. Practice gratitude by regularly writing down positive memories. Keeping your mind open and asking for things that are nice and beneficial in life allows you to find joy and fulfillment. Doing these activities can broadly improve your immune system, helping your body recognize threats that may otherwise go unnoticed. They can help keep you physically active in an effective way. Finally, remember, nobody is perfect, we're all different. It's impossible to live a virus-free life, but at least everyone can strive to live a healthier lifestyle.

5. Maintain a Positive Attitude. Surrounding yourself with happy, kind, helpful people encourages you to see the best in everything that happens to you. Having a sense of optimism reduces stressful thoughts and makes you happier. If you are feeling anxious and stressed, try looking for ways to deal with or improve those feelings rather than look inward and dwelling on bad things. Being proactive instead of reactive can play a crucial role in keeping your head up and your spirits up. Research over the past few years suggests that having a positive attitude could help reduce inflammation. People who had a more optimistic outlook were 17 percent less likely to experience pain after surgery and 29 percent less likely to report psychological distress during times of acute stress. Taking action is the most potent way to reverse these harmful effects on your own body. By changing your outlook on life, you'll start enjoying the present while learning to appreciate the journey ahead.

6. Eliminate Smoking Tobacco. Nicotine creates cravings for nicotine cravings. As soon as you get hooked on cigarettes, it doesn't seem to matter what you eat or drink. Just give in! That's how addiction works. Smokers don't smoke tobacco because it tastes good; they smoke tobacco to satisfy their craving for nicotine. It's true, your desire may not necessarily be satisfied immediately after lighting a cigarette. Nicotine tends to wear off within 10-20 minutes, especially as you begin to feel fatigued or sleepy even if you aren't smoking to get a quick fix. Plus, research shows that smoking cigarettes damages the lung and heart, increases inflammation
