How to boost immunity for back to school

Back to school is a key time of year, marked by new challenges and seeing friends again, but also by greater exposure to viruses and bacteria typically found in school environments. To protect health during this period, it is essential to strengthen the body’s defences and maintain habits that support the immune system. Adopting healthy routines can help both children and adults face the return to the classroom more safely.

How can we strengthen our defences and energy levels?

When summer ends and we return to our routine, children and adults find themselves in a more enclosed and concentrated environment that may be full of viruses and bacteria, making them more exposed to them.

This can lead to low defences and make us fall ill more easily. That is why it is so important to support the immune system at this time of year, preparing it for the return to school so that we do not keep getting ill and can also perform better while staying in good health.

Low immunity: why does it happen?

There are times when changes in our routine are reflected in our defences. For example, changes in schedules, changes in temperature as the weather gets colder, less sun exposure and therefore lower vitamin D levels, a return to academic or work-related stress, or more contact with people in more enclosed and poorly ventilated spaces. All of this directly affects the immune system, leading to consequences such as:

  • More colds.
  • Tiredness and lack of energy.
  • Lower physical and mental performance.
  • Greater risk of more serious respiratory infections.

Keys to supporting the immune system

Despite everything mentioned above, there is advice to improve and strengthen the body’s defences and immune system. Both healthy lifestyle habits and supplements can help provide extra support for people who need it:

  • A varied and balanced diet. A healthy immune system: including foods rich in essential micronutrients, such as fruit, vegetables, pulses and quality protein, provides a large number of vitamins such as A, C, D and E. It also supplies minerals such as zinc, selenium and iron, which help the body work properly and maintain a healthy immune system.
  • Getting enough rest to achieve quality sleep: ideally, people should sleep between 8 and 10 hours depending on their needs. Getting enough rest is essential for cell regeneration and the production of cytokines, which are involved in defending the body against infections.
  • Regular exercise: physical activity, especially outdoors, is very important for improving mood and supporting the body’s defences because it helps promote vitamin D production, a vitamin that is essential for the immune system.
  • Nutritional supplements: if we have a deficiency or need extra oral support with these micronutrients, supplements can help provide them. This can be especially useful during periods of greater wear and tear or seasonal changes, when the body is more exposed to environmental factors that weaken our defences.

What supplements can I take for this?

  • Bion 3 Defence: this multivitamin supplement not only provides micronutrients that help support the immune system, but also improves gut flora so that the body can better defend itself against external agents that may trigger an infection or illness.
  • Inmunomix: this product acts as a protective barrier in the oral cavity against external agents that may cause infection, such as bacteria or viruses, as well as irritants such as dust, smoke, dry air or pollution.
  • Naturamix Reinforcement: it is very effective during periods of greater tiredness or physical wear. Above all, it helps improve tiredness and fatigue thanks to ingredients such as royal jelly and cyanidin, a combination of red berries.
  • Multicentrum Double Energy: this option focuses more on energy production and improving vitality, especially thanks to ingredients such as vitamin B12, vitamin C and other B vitamins, as well as minerals such as magnesium, calcium and zinc.
  • Naturcomplex Vitamin C: vitamin C could not be missing from this list. Among its functions, vitamin C helps support the immune system and also improves tiredness and fatigue, which is why it deserves a place here.

It is important to mention that none of these products will replace a balanced diet. We still need to get the nutrients we need through food. Even so, during periods of greater demand or tiredness, supplements such as those mentioned above can be a very good option to support the immune system and reduce tiredness and fatigue so that the return to school is as manageable as possible.
