The immune system It protects our body from viruses, bacteria and fungi, acting as a shield against infections and various diseases.
However, there are some factors that weaken the immune system, making it more vulnerable to diseases.
In addition to exercise And quality sleep, our eating habits play a key role, as well as the cessation of smoking.
Below are the main factors that negatively affect our immune system.
Malnutrition
The bad diet It is one of the main causes that weaken the immune system. Foods that are high in sugar, processed fat and salt reduce the efficacy of the immune system as they cause inflammation in the body.
When we consume foods that are “poor” in nutrients, our body does not have the necessary supplies to produce appropriate antibodies. To strengthen our immune system we need vitamins, minerals, antioxidants and healthy fat, which are found in foods such as fresh fruits, vegetables, nuts and, of course, fish.
Lack of sleep
Lack of sleep is another factor that weakens the immune system. During sleep, the body is renewed and strengthens the immune system. The prolonged lack of sleepHowever, it can reduce the production of white blood cells, which contribute to the fight against infections.
According to surveys, people who sleep less than 7-8 hours per night are at greater risk of developing inflammation and diseases, as their immune system does not have time to recover.
Stress
In turn, stress has a negative impact on the immune system. When we are stressed, our body produces more cortisol, a hormone that suppresses the function of the immune system. Increased cortisol makes the body more vulnerable to infections and inflammation. In addition, chronic stress can lead to insomnia.
Smoking
The smoking It is one of the worst health habits and has catastrophic consequences for the immune system. Toxins found in cigarette smoke damage the immune cells and make the body more prone to infections and diseases.
In addition, smoking reduces the effectiveness of cells that fight viruses and bacteria, increasing the risk of various diseases, such as chronic obstructive pulmonary disease (COPD).
Sedentary life and lack of exercise
Sent life is another habit that has serious consequences for the immune system. Physical activity enhances the body’s defense as it improves blood circulation and helps renewing cells.
Exercise also helps to reduce inflammation and helps the body fight infections. On the contrary, lack of exercise can make the body more vulnerable to diseases.
