What makes our immune system tick?

Our immune system has the task of protecting our body from harmful substances and infections. All immune cells in our body, which are responsible for the recognition and elimination of foreign substances, form our immune system. The first protective layer is formed, for example, by the skin with the production of sebum or also the eyes with a liquid film.

Once the harmful substances have cleared the first hurdle of the immune system, it is the turn of the internal defense mechanisms. These are all endogenous substances designed to block the development of the dangerous pathogens.

In addition to this non-specific immune system, there is also a specific immune system that specifically targets very specific foreign substances in the body (so-called antigens). Your immune system works like your Internet browser: If you have been to a website before, it usually loads faster the next time you visit it, because the browser has remembered the data.

In the same way, your immune system remembers which foreign substances have already been fought in your body and reacts more strongly and quickly to this harmful substance the next time. That is our immune system in a nutshell. Now you can learn what you should do every day to permanently strengthen your defenses and immune system and get sick less often.

11 valuable tips to strengthen your defenses

This post is about how to take your health into your own hands and personal responsibility. Completely in the sense of Salutogenesis is about strengthening your health and thus becoming as resistant as possible to the causes of disease. Replacing a few old habits with healthy behaviors will strengthen your defenses and support your immune system. Here now the promised eleven valuable tipsto strengthen your defenses.

Yoga is a beautiful form of exercise to strengthen the immune system.

1. move - exercise for strong defenses

On average, Germans move only 650 meters a day. That's an alarming figure. Because our bodies are actually made for movement. If you move, you strengthen the function of your immune system. It's best to plan three activities a week in which you get enough exercise for at least half an hour. Three times a week for 30 minutes is absolute minimumYou should do this for yourself and for your health.

Tip: Personally, I believe that we should exercise extensively every day. Of course, that doesn't mean you should do a hard workout every day. But instead, you can do some casual exercise every day, such as gentle yoga or a walk.

Make sure you don't overdo it, because too much exercise is permanent stress on your body and immune system. I myself tend to exercise too much. With 2 fitness sessions and 2 running sessions a week, I have now found a good rhythm of exercise.

All well and good, but you lack motivation? Use motivating playlists that have been specially compiled for training sessions. Or make a date with friends for sports, so you can motivate each other. By the way, it is not necessary to invest a lot of money and time in gyms. For my training, I made these one-time purchases that allow me to do my CrossFit program easily anywhere, anytime:

My fitness equipment

With one-time just under 80€ I can now train flexibly and everywhere and strengthen my defenses. For easier transport of the mat I bought a backpack with fixable straps. Exercising regularly is crucial if you want to strengthen your immune system.

2. relax - strengthen the immune system in a relaxed way

Rest is good for your immune system
Rest strengthens your immune system

Our fast-paced society can put us under a lot of stress. Like yourself, your defenses are then stressed. If you are permanently under power, you are in the sympathetic system all the time. Sympathetic sounds good at first, but it has a negative effect. sympathetic system stimulates and makes the body ready for fight or flight in case of danger.

When stress or anxiety causes us to experience the so-called Fight or Flight mode activate, our immune system shuts down. Because if we were afraid of a tiger in prehistoric times, we used up all our energy for the race and our immune system went blank. This was not a problem at that time, because after the successful escape, there was no more fear and stress and the body was functioning normally again. Nowadays, most people are under constant stress and are permanently confronted with fears, especially through the media.

When something puts you under stress, your cells release more of the hormone cortisol, which inhibits the function of your immune system. Your parasympathetic system promotes regeneration, digestion and has a calming effect. So if you want to activate the parasympathetic nervous system, you should consciously take breaks, relax and slow down. Ideal for this are Yoga and MeditationBy consciously slowing down your breathing, you automatically switch to the parasympathetic system and reduce stress. This way you can easily strengthen your immune system and stay healthy more easily, because relaxation is just as important for the immune system as exercise.

3. less smoking & binge drinking - For stronger defenses

CigarettesBeer and other beverages weaken your immune system and make you more susceptible to illness. Your defenses are inhibited and can block harmful substances only with difficulty. The white blood cells are supposed to destroy the harmful substances in your body, but they can't do that if you smoke. A heavy alcohol intoxication inhibits your immune system. It is better to drink alcohol consciously and in moderation to minimize the burden on your immune system. The best thing, of course, is to stop drinking alcohol altogether.

4. sleep' better - Seldom ill through better sleep

Sleep to strengthen immune system and get sick less often
Sleep at least 7 hours every night

Do you sleep less than seven hours a night? With so little sleep, your immune system can't produce enough white blood cells and you're more susceptible to getting sick. Strengthen your immune system by getting more than 7 hours of sleep a night. Quite simple, but not self-evident. I know it from myself that I don't like to go to bed early. Nevertheless, with enough sleep you can strengthen your immune system immediately.

Besides the quantity, however, is also the Sleep quality especially important. At least one hour before going to bed, you should give up your cell phone and laptop to avoid the blue light of the screens. This is because the light stimulates you, increases your adrenaline level and lowers the production of the sleep hormone melatonin, making it harder for you to fall asleep.

It's best to get a light alarm clock and turn your cell phone off at a certain time, because then the temptation to answer your cell phone again is really very low. And a light alarm clock also makes getting up more relaxed, as it wakes you up more gently than a shrill alarm. Here are some more tips that will help you sleep better and stay healthy!

5. off to the sauna - healthy temperature change

Maybe you know this: You come back from a warm beach vacation (see Nature Travel Blog) back to cold Germany and immediately get sick. The sauna can prepare your immune system for such temperature changes. The rapid temperature changes from cold to hot strengthen your immune system and make you less susceptible to illness. Especially in autumn & winter you should go to sauna to strengthen your immune system and get sick less often. But also in summer a sauna visit makes sense. Your body is optimally prepared for temperature differences through the sauna and thanks you with stronger defenses.

6. cold showers or ice baths - cold strengthens the immune system.

You can achieve a similar effect as with the sauna by ice bathing. The cold exposure strengthens the body's temperature regulation, blood circulation and the autonomic nervous system. It is best not to start with an ice bath at the beginning, but to turn the water colder and colder while showering until you end up with a very cold shower. Bit by bit you can then extend the time under the cold water until you shower completely cold. Then you will be ready for your first refreshing ice bath. You can find more information in the article about Cold showers & cold training.

7. off into the sun - strengthen immune system with sunlight

Soak up the sun for a strong immune system

Admittedly, this is not always easy in Germany during the cold season. Then just move your beach vacation to this time of year and go to the south. Or take time for a walk during your lunch break, so you can at least get some sun and fresh air. Because these are important for the Vitamin D-production of our body. And the sun vitamin has a huge impact on the immune system.

8. detox - healthy gut for stronger defenses

Almost 80 percent of our immune cells are located in the intestines, so a strong immune system needs a healthy intestine and vice versa. Your intestine regulates your water balance, produces hormones and forms the majority of the defense cells of your immune system. It is therefore logical that your intestines should be in absolute good shape so that your immune system is strengthened and you are sick less often.

To keep your intestines as clean as possible, a whole plant-based diet, fermented foods will help you, Intermittent fasting and Fasting cure or this purification tea*. This way you can stimulate natural regeneration and detoxification, which also strengthens your immune system.

9. forest bathing - terpenes for your defenses

In the meantime, it has been scientifically confirmed that the terpenes found in the forest have the Killer cell production in your body, which kill viruses and cancer cells. In addition, you regulate blood pressure and pulse and can therefore relax better. I have already described how good relaxation is for your immune system.

A forest bath is a great way to combine several factors that strengthen your immune system. With exercise, relaxation and time in the fresh air, you're sure to stay healthy for a long time. You can find more information in our separate article on the Forest bathing.

10. barefoot walking - stimulus for the immune system

Barefoot running stimulates blood circulation, perception, and the body's own temperature regulation, thus strengthening your immune system. In addition, barefoot running improves your posture, strengthens your foot muscles and maintains the health of your joints. You can find more information in the article on Barefoot running. Maybe you'll take your next forest bath barefoot and strengthen your immune system in a special way.

11. whole food nutrition - plant power for the immune system

A wholesome diet ensures that you are well with Nutrients are supplied. Zinc, Vitamin A, C and D are just a few examples of nutrients that strengthen an immune system. With the most complete and unprocessed diet possible, you automatically provide a high nutrient density and can reduce nutritional stress from refined, isolated nutrients and empty calories like those found in sugar or white flour. Optimally, you still complement your healthy diet with a few high quality food supplementsto optimally supply your defenses.
