The human body is a fascinating machine, and so are its mechanisms and processes. One of the most interesting ones is the immune system: learning how our body defends itself against disease and infection has intrigued humans for millennia.

One of the earliest immunological observations recorded is the one by Thucydides, a Greek historian and military man who around 430 B.C. noted that there were people who, during an outbreak of plague in Athens, were lucky to recover and did not contract the disease a second time.

The modern study of the immune system began with scientist Luis Pasteur in the mid-19th century, when it was scientifically identified as a protector against infectious diseases. From then on, research has become more refined, and new discoveries are made regularly.

For example, during the past 20 years, researchers have discovered the immune system’s crucial role in development, reproduction, and wound healing.

How to Develop a Healthy Lifestyle to Support the Immune System

The importance of the immune system to our overall wellbeing is obvious, so take care of it. What we put in our bodies, as well as how we take care of ourselves, all contributes to our well-being. Remember, nutrition doesn’t prevent illness but helps maintain a normal, healthy body’s systems. Nutrition is not a substitute for medical care.

Here are 5 personal wellness and nutrition habits to support your immune system:

1. Maintain a balanced diet.

When it comes to the relationship of the immune system with nutrition, there are some key aspects to keep in mind:

Avocado is another great source of unsaturated fats and may also support brain function. Try to find ways to include it in your diet. Here are some examples:

Here in Mexico, we use this ingredient in many of our dishes. In fact, we are the world’s largest avocado exporter. In 2020, Mexican avocado exports amounted to more than 2.7 billion U.S. dollars. In that year, the United States alone accounted for approximately 80 percent of the value of avocado exports from the country.

2. Wash your hands correctly.

According to the Centers for Disease Control and Prevention, washing your hands can eliminate microorganisms and help avoid the transmission of diseases.

After washing your hands, apply hydrating cream and paraben-free products to take care of your skin.

3. Rest effectively.

Adequate and healthy sleep time varies with age, but adults should aim to get at least 7 hours of sleep per day. Improving your sleep hygiene habits can help you obtain a better quality rest, which will help to restore any metabolic damage and thus maintain balance.

4. Exercise regularly.

Research has shown the positive impact of exercise on the immune response:

Doing physical activity for at least 30 minutes five times a week is a sound recommendation for adults to maintain a healthy lifestyle.

5. Drink enough water.

Good hydration is essential to maintain the balance of minerals and fluids that our immune and respiratory systems need to work properly. Water constitutes around 70 percent of our total body mass as adults and is distributed both in intracellular (65 percent) and extracellular (35 percent) spaces, which is why it’s so important to keep hydrated.


The immune system plays a key role in keeping your body in balance and well, so taking care of it will go a long way.
