What is the difference between people who are prone to allergies and those who are not?

An allergy is a condition in which our immune system overreacts to substances that are not normally harmful (such as pollen or food) as "foreign bodies." Whether or not an allergic reaction occurs varies greatly from person to person, and genetic, environmental, and lifestyle factors play a role.

1. Genetic factors
People who are prone to allergies often have a genetic predisposition. For example, if a parent has an allergic constitution, their children also tend to be at higher risk. In particular, allergic diseases such as asthma, atopic dermatitis, and hay fever often run in families. However, genetics is not the only cause, and interactions with the environment also play a role.

2. Environmental factors
The childhood environment also plays a role in the development of allergies. Children living in urban areas are said to be at higher risk of allergic diseases than those living in rural areas. This is thought to be related to air pollution and exposure to chemicals in urban areas. There is also a theory called the "hygiene hypothesis." This hypothesis posits that if children have few opportunities to come into contact with a variety of microorganisms during childhood, their immune systems do not mature sufficiently, making them more susceptible to developing allergies.

3. Lifestyle and diet
Diet, stress, and lack of exercise also affect the onset of allergies. For example, consuming a lot of dietary fiber and fermented foods can improve your intestinal environment and lower your risk of allergies. On the other hand, processed foods and high-fat, high-sugar diets can worsen your intestinal environment and increase your risk of developing allergies. Stress can also cause your immune system to become unbalanced, worsening allergy symptoms.

4. Characteristics of people who are less susceptible to allergies
People who are less likely to develop allergies are characterized by having properly functioning immune systems. This is not only due to a low genetic risk, but also because their daily lifestyle and environment often support immune function. For example, a diverse diet, moderate exercise, and sufficient sleep strengthen the immune system. In addition, spending more time in nature provides opportunities to come into contact with a variety of microorganisms.

Summary <br data-mce-fragment="1">The difference between people who are prone to allergies and those who are not is a complex intertwining of genetic factors, environment, and lifestyle habits. In particular, the diet, stress management, and exercise choices we make in our daily lives can greatly affect our risk of allergies. A balanced lifestyle is important to maintain a healthy immune system. Why not take a look at your own constitution and living environment to prevent and manage allergies?
