6 signs of a weak immune system

A healthy immune system is responsible for keeping the body safe from foreign viruses and bacteria that attack the healthy cells in the body. In this manner, it plays a huge role in warding off any infections or diseases. However, some factors can weaken the immune system over time, including unhealthy lifestyle choices, environmental factors, and genetic factors. Thus, here are some signs and symptoms to look out for that indicate a weak immune system.

Frequent illnesses
This is a very common symptom in anyone with a poor immune system. One may catch colds easily, and the symptoms that usually go away in a week last for longer. These individuals are also susceptible to getting food poisoning easily, which may take more than a couple of days to get treated. There are some barrier responses from the immune system which usually helps keep illnesses in check, and this includes:

Cough reflex, which helps in expelling any foreign object which suddenly causes irritation.
Stomach acid, which helps in killing the microbes which can enter the body through the food and drinks consumed.
Mucus production, which helps in trapping bacteria and any other small particles which can cause irritation or cause infection in the body.

In a weak immune system, these barrier functions are unable to function optimally, resulting in more frequent infections or illnesses.

Constant stress
Chronic stress is a cause and effect of an unhealthy immune system, so it is important to keep the stress levels in the body in check. The stress causes immune dysregulation and also leads to immune suppression. This, in turn, can cause other complications like increased infections and diseases in the body and a slower recovery process that keeps the body in a stress mode. Stress can also trigger autoimmune diseases like eczema, rheumatoid arthritis, ulcerative colitis and asthma.

Frequent cold sores
Shingles and cold sores are diseases caused by the herpes virus. Once the virus enters the body, it remains dormant until factors leading to developing cold sores or shingles trigger it. These triggers include stress or even cellular immunity weakness. When the virus replicates itself and reacts in the body repeatedly, it is a sign that the immune system is weak and cannot fight off the virus to the best of its potential. This is when immunity boosters are required to treat some symptoms.

Stomach issues
The gut contains millions of bacteria that needs the right kind of food and nutrition to help it thrive. These bacteria are important for the functioning of a healthy digestive system as they help in keeping the gut clean. There are many studies to suggest how good gut health can influence overall health. However, if someone is experiencing chronic stomach problems like constipation, diarrhea, gas, and similar digestive issues, it indicates that the gut health is not ideal. This could be due to a weak immune system, which does not provide the healthy environment for the good bacteria to thrive.

Slow healing
Slow recovery and healing is a major indicator of a weakened immune system. The healing process involves sending nutrient-rich blood and healthy immune cells to the cut, scrape, or burn on the skin. When the immune system is sluggish, this healing process becomes much slower, and the regeneration of new skin is also slower. So, keep an eye out for these small signs and symptoms that could indicate a slow immune system.

Lethargy
If you are getting enough sleep and still suffering from weakness and lethargy, this could indicate that the body is pointing towards a tired immune system. When the immune system is struggling to keep the body active and energized, despite no physical exertion, it indicates the presence of an issue. This lethargy usually means that the immune system is trying to reserve its energy so it can fight off germs in the body.

There are some ways to keep the immune system healthy, and this involves strict lifestyle changes on a daily basis. Eating nutritious food every day for each meal is of utmost importance to keep the body running on good fuel. Enough sleep, exercise, and minimizing stress are also some of the key points in keeping the immune system less burdened and healthy.

4 hair styling tools that give a salon-like look

If you like to style your hair frequently without having to spend money at salons, you can invest in some basic hair styling tools. These tools can create beach waves or curls or even straighten them out. There are many hair styling tools that are versatile, easy to use, and do little or no damage to your hair. If you want to invest in hair styling tools, here are a few tools to check out: Hair straightener and curler Combining a hair straightener and curler that is suitable for all hair types allows you the freedom to try out trending hairstyles. Look for a professional straightener or curler with a ceramic or copper flat iron. Choose a flat iron that allows you to control the temperature so that you don’t damage your hair. Experts claim that setting the straightener or curler to temperatures as high as 455 degrees can help straighten the most challenging and rigid curls. The copper ceramic tools also ensure that the hair doesn’t break while you are straightening, leaving your hair straight and smooth once you are done. You can also choose regular and smart Bluetooth straighteners to help you choose the best temperature and care settings every time you use the tool. Hot air brush Hot air brushes combine a hairbrush with a flat iron and blow dryer. Choose the desired heat setting and gently brush your damp hair. It is essential to remember a hot air brush cannot be used on wet hair or right after your shower; your hair needs to be dry by at least 80%. It works well with mildly damp hair. The bristles in the hairbrush guide your hair, and the heated plates smooth and polish it. You no longer need to use a hair dryer to dry your hair after a shower and then use a straightener.

8 effective remedies for nasal polyps

Nasal polyps are tiny tear-shaped growths in the nose and sinuses, usually brought on by asthma, infection, allergies, or other kinds of inflammation. These polyps are usually painless and non-cancerous, however, they can be big enough to cause itchiness, breathing difficulties, sneezing, and running nose. Doctors usually prescribe nasal sprays that can relieve the symptoms and get rid of the polyps. However, one can also try a few natural remedies to deal with the condition: Neti pot (or nasal irrigation) Neti pot is a popular and convenient nasal irrigation device. All one has to do is fill this container with saline solution or add 1–2 tsp salt to distilled water or boiled (and then cooled) tap water. Then, one would have to lean over a washbasin or a sink and tilt their head sideways so that the liquid does not flow back into the mouth. One would have to breathe through the mouth, insert the spout into the upper nostril and allow the fluid to drain from the lower nostril. Then the nostrils will have to be cleaned by blowing the nose to remove mucus and dirt. This process should be repeated through the other nostril. The goal is to loosen and clear the mucus and debris like dust or pollen from the nasal cavity. Using a neti pot twice a day can help improve symptoms of nasal polyps. The container and hands have to be clean and dry to prevent infection. Steam inhalation In the absence of a nasal irrigation device, one can use steam to relieve nasal congestion, headaches, and other symptoms. People can boil some water in a pot or dish, place it on a counter or the dining table right in front of them as they sit in a comfortable position, and inhale the steam for a while.

4 foods that are surprisingly bad foods for diabetics

Many foods are portrayed to be the best for diabetics, but it would be surprising to know that even wholesome foods could cause a spike in sugar levels if the portion size is not moderated. Food choices truly matter when a person has diabetes. Under normal circumstances, one would think that these foods aid in better health and maintain sugar levels, but they don’t. Here are four surprisingly bad foods for those with diabetes: Brown rice While brown rice certainly has more fiber than white rice, a single cup of brown rice contains nearly 50 grams of carbohydrates. This can easily be broken into glucose which could spike the sugar levels. The alternative would be to cut down on rice and add more green leafy vegetables. Fresh fruit juice It does not matter if one opts for seasonal juice or those that claim that they have no extra sugar added. If we take an orange as fruit and look at its nutrient content, it has about 15 grams of carbohydrates, vitamins, and fiber. An orange juice, on the contrary, has 45 grams of carbohydrates and less of other nutrients. Therefore, drinking juice is not the same thing as eating fruit.   Dried fruits If one thinks having a raisin is healthier than a chocolate cookie, think again. Raisins contain 1 gram of carb more than what is available in a chocolate cookie. That said, they are undoubtedly wholesome compared to a cookie. However, both of them would result in a spike in blood sugar. The same holds good for cranberries and apricots. Yogurt Yogurt offers a plethora of health benefits, including probiotics for gut health. However, they are heavily processed and contain a wallop of 30 grams of sugar, even in the best of the brands. Ensure to read the ingredient before buying one.
