Many teenagers push their bodies hard. They stay up late, have poor eating habits, and spend hours glued to their mobile device. School stress, stemming from the need to perform well academically and in extracurricular activities, can also take a toll on their health.

With all these things going on, it’s no surprise their immune systems can get worn down.

The good news is you don’t need to overhaul your teen’s entire lifestyle to help them boost their immune system. A few consistent, manageable changes, such as giving them MAF supplements and modifying their diet, can go a long way in helping them stay healthy and feel energised.

With the right steps, you can help strengthen your teen’s natural defences and help them bounce back faster when an illness does strike.

Stress and Your Teen’s Health

According to a report, 75% of students in the USA reported experiencing stress at school. This means many teens are affected by their schoolwork and other activities regularly.

This stress can cause anxiety, withdrawal, physical illnesses, and a weak immune system.

But how does chronic stress affect the immune system?

High levels of cortisol, catecholamines, and other stress hormones can suppress immune cell activity and disrupt cytokine production, leading to reduced immunity.

They can reduce the production of white blood cells, which impacts the body’s ability to fight infections.

Chronic stress can also cause the release of inflammatory markers, which puts teens at a higher risk for low immunity and other chronic health issues.

Helping Your Teen Strengthen Their Immune System

Below are some ways you can help your teen if you’re worried about the harmful effects of stress on their immunity and overall health:

1.     Ensure your child gets enough sleep every night.

If you want to boost your child’s immune system, start by encouraging them to sleep earlier every night.

Inadequate sleep is one of the common factors that weakens one’s immune system. Studies show that sleep deprivation alters the profile of immune cells, making them more similar to those found in people with obesity. This variation can cause the onset of chronic inflammation.

According to the Sleep Foundation, teenagers should get eight to 10 hours of sleep per night. Unfortunately, many teens tend to sleep only 6.5 to 7.5 hours nightly due to homework, extracurricular activities, and social activities.

Most teens also tend to stay up late because of their changing biological clocks and online activities.

To ensure your child gets enough sleep every night, help them create a detailed daily schedule that includes eight to ten hours of shut-eye. It should state the time they need to complete their homework or projects and do their revisions so they don’t affect their nighttime routine.

It should also include the amount of time they are allowed to use their devices.

Also, teach your teen a pre-bed routine to help them relax and fall asleep fast at night. Remind them to avoid drinking caffeinated beverages in the afternoon and early evening and to put away their electronic devices 30 minutes before bedtime.

Ensure your child follows this timetable every day, whether on a weekday or a weekend, to build a healthy, immunity-friendly sleep routine.

2.     Modify your teen’s diet.

A study shows that malnutrition can cause immune dysfunction. Many teenagers are undernourished because they don't eat properly, especially when they’re in school or hanging out with friends.

You can help your child get the nutrients they need to have a strong immune system by giving them healthy foods at home.

Incorporate more vegetables, fruits, nuts, seeds, and oily fish in the meals and snacks you prepare at home. These foods are great natural sources of vitamins, minerals, and other nutrients that strengthen the body’s immunity.

Wholemeal or whole-grain foods, such as brown rice and pasta, whole-wheat bread, and oats, are also packed with nutrients that support the body’s immune system.

Besides combining these ingredients to make salads, you can use them to create healthy stews, pasta dishes, sandwiches, and other meal and snack staples your teen can enjoy eating daily. These nutritious options help fill the gaps in their diet when they eat out.

3.     Encourage your teen to drink more water.

Carbonated and sugary drinks are part of many teenagers’ daily diet. Unfortunately, they are unhealthy beverages that affect a person’s immunity.

A report states that carbonated beverages, which contain large amounts of sugar, can alter the DNA of gut bacteria, thereby affecting the immune system.

Whether your child drinks sugary drinks or not, encourage them to drink more water. By doing so, they can flush waste and toxins from the body, which supports the immune system.

Water also aids in the absorption of vitamins and other nutrients that help keep the body healthy.

Remind your child to drink six to eight cups of water daily. Have them bring a water bottle so that they can drink at school.

Also, remind them to drink more water and fewer energy drinks while and after playing sports or engaging in any physical activity.

4.     Give your child additional supplements.

Some teens may need to take supplements to ensure they get the nutrients they need to avoid deficiencies and improve their overall health. These nutrients include vitamins C and D, zinc, and selenium.

You can also consider adding GcMAF supplements to your child’s diet. Gc protein-derived macrophage activating factor (GcMAF) is a natural protein in the body that activates macrophages, substances that defend the body against infections and diseases and strengthen the body’s immune system.

When activated, macrophages enhance immune memory or the ability to recall previous infections and illnesses. When the immune system encounters the same bacteria and other harmful microbes, it responds more quickly and effectively to protect the body.

GcMAF supplements can also activate microglia, macrophages or the primary immune cells located in the brain and spinal cord. These cells detect infections and signs of cellular distress, and fight these threats.

Additionally, activated macrophages help regenerate lymphocytes, which help heal the immune system.

They also support immune system healing by regenerating lymphocytes. You can learn more about the supplement’s health benefits by reading GcMAF research papers.

GcMAF supplements come in capsules, powder, and lollies, giving your teen options to find the best one for their preferences.

Consult a doctor before suggesting any supplements to ensure you give your teen the right ones in the correct doses.

5.     Schedule tech breaks.

Too much screen time, especially at night, can affect your child’s sleep quality and increase stress, factors that weaken immune function.

Blue light also disrupts melatonin production, making restful sleep more difficult.

Have your child take short tech-free breaks regularly throughout the day by unplugging from their phone, tablet, or computer for several minutes. Ask them to use this time for activities that calm the nervous system, such as walking or stepping outside for some fresh air.

Remember to set clear limits around screen use before bed to help your teen rest and fall asleep faster.  

By making these changes, you can boost your teen’s immune function and help them stay energised and ready to take on whatever life throws their way.
