Frequent illnesses indicate a weak immune system? These 7 signs suggest a poor immune system.

Some people seem unafraid of the flu season, rarely even sneezing. But others get sick easily, especially in autumn and winter; they seem to be constantly wiping their noses with tissues, and their coughs never stop. In this article we will mention warning signs of weak immune system.

What’s the difference between these two types of people? Research shows that each person’s ability to resist viruses may be related to some daily habits, such as sugar intake or the dryness of the nose.

Based on a report in the American magazine “Prevention,” see if you have these signs of a weakened immune system, and learn how to boost your immunity through daily life.

7 types of people who are prone to weakened immunity

01 Eating too many sweets

Consuming too much sugar does more than just make you gain weight. A study published in the American Journal of Clinical Nutrition found that consuming 100g of sugar (about the sugar content of three cans of carbonated drinks) can significantly impair the bactericidal ability of white blood cells , with effects lasting up to 5 hours.

02 Drinking too little water

When you’re sick, your mom and doctor will constantly tell you to drink more water, and this isn’t just empty talk. Your body needs water to help detoxify, and insufficient water intake can affect your immune function. This one is a common warning sign of weak immune system

Healthy urine is pale yellow. Urine that is too yellow indicates that you are not drinking enough water, while urine that is too clear indicates that you are drinking too much water.

03 Overweight or Obese

Excess weight can affect the health of the heart, brain, and other organs, as well as immune function. Studies have found that most people who became severely ill with swine flu had one thing in common: a body mass index (BMI) of over 40, meaning they were morbidly obese.

Excess weight can trigger hormonal imbalances and inflammation, weakening the immune system.

04 Drinking raw water

​The cleanliness of drinking water can also determine a person’s chances of getting sick. In the United States, approximately 25 million people drink tap water with excessive levels of arsenic. Arsenic is linked to many cancers and can also affect the body’s immune system’s ability to fight off swine flu. This one is a common warning sign of weak immune system

Researchers at Dartmouth Medical School injected two groups of mice with the HINI virus . One group of mice had been drinking water containing arsenic for five weeks, which severely damaged their immune systems, and many of them died after the injection. The other group of mice, which did not drink the water, contracted a cold but eventually recovered.

05 Dry nose

Although a runny nose is inconvenient, it’s a mechanism the body uses to fight off colds and flu; the mucus secreted by the nasal cavity helps expel viruses. If the nasal cavity is too dry, it can actually make it easier for viruses to invade the body.

If the dryness is temporary, you can rinse your nasal cavity with a nasal irrigator, or use a humidifier. However, if it is chronic dryness, you may need to consult a doctor to determine the cause. This one also a common warning sign of weak immune system

06 High pressure

It’s no coincidence that many people catch a cold after a major workday. A report from the American Psychological Association states that chronic stress weakens the immune system.

“If you’re stressed during a cold, the symptoms can become more severe,” said Dr. Philip Tierno, chair of the Department of Clinical Microbiology and Immunology at New York University.

07 is always catching colds and getting sick

This means your immune system isn’t fully engaged. Generally, adults get an average of 1-3 colds per season, each lasting 3-4 days. If you get more than that, it indicates your immunity is somewhat weak.

Remember to get enough sleep, exercise regularly, and stick to a healthy diet rich in vegetables.

5 nutrients to boost immunity

Proper nutrition can improve the body’s immune system. In addition to a balanced diet, supplementing with these nutrients can help boost immunity.

protein

Protein is part of the body’s defense mechanisms. Foods that contain a variety of proteins in the diet include seafood, lean meat, poultry, eggs, beans, soy products, unsalted nuts, and seeds.

Vitamin A

Vitamin A helps regulate the immune system and fight infection. Deficiency can cause keratinization and degeneration of the epithelial cells of the respiratory, digestive, urinary, and reproductive systems, making them more susceptible to bacterial invasion and increasing the risk of respiratory and intestinal infections.

Foods rich in vitamin A include sweet potatoes, carrots, cabbage, spinach, red bell peppers, apricots, and eggs.

Vitamin C

Vitamin C has antioxidant properties and is an essential vitamin for the human immune system. Citrus fruits (such as oranges, grapefruits, and tangerines), red bell peppers, papayas, strawberries, and tomato juice are all rich in vitamin C.

Vitamin E

Vitamin E is an antioxidant in the body and also an effective immune modulator, which can improve the body’s resistance to infection. You can eat more fortified oatmeal, sunflower seeds, almonds, rapeseed oil, hazelnuts, and peanut butter.

Zinc

Zinc is a component of over 100 enzymes in the human body, playing a crucial role in the development of the immune system and the maintenance of normal immune function. It can be obtained by consuming more lean meat, poultry, seafood, milk, whole grains, legumes, seeds, and nuts.
