Currently there are a couple of commercials selling pain and fever relief products for children. The emphasis of the commercials is that they take away the worry of a fever from the Mum. You see (a perfectly groomed) Mum stating how using this product makes her life easier because she can stop her child’s fever straight away. These commercials make me angry! Why, because fever is the body’s natural defence against infection and is not something to be feared or eliminated. If you shut down the body’s natural defence against something, how do you think the immune system can fight the infection? What are the long term effects of suppressing a young child’s developing immune system?
I am a Mum and I understand that we don’t want to see our children in pain or distress, but I also trust in the body’s innate power to heal itself. I get very annoyed at pharmaceutical companies who operate on fear tactics and contribute to Mums stress and worry by telling them that the best way to treat their children is with a man made drug. So how does the immune system work and how can you provide natural support to your immune system?
Your immune system is one of the complex systems on the planet. It is highly evolved and is able to cope with an amazing diversity of challenges. The problem however is that the amount of things our immune system has to cope with is increasing. Our world is not becoming cleaner, but it is rapidly changing, with new chemicals and toxins produced everyday.
Your immune system consists of an amazing system of immune cells and tissues whose sole purpose is to defend your body against viruses, bacteria, allergens and parasites. If you think of your immune system as an army, which is on constant surveillance and fights invaders when required. There are different types of immune cells, each with their own role to play just like different ranks in the army. Now if you don’t feed your army well and look after it, what do you think will happen when are larger invader comes along? Your army (immune system) won’t have the strength or reserves to fight and the battle may continue for a long time and then start to spread to other areas. An army which is out of control can start to attack itself, this is called an auto-immune condition.
So what happens when you immune system detects a foreign pathogen like a virus? Firstly it is important to understand how virus spread. When a virus gets into a cell, it replicates itself within the cell’s DNA then the new virus bodies push out of the cell wall forming little buds on the cell wall. Each of these buds will move onto another cell and replicate itself in the cell and the process starts again. While this process is happening in the cells the immune system is increasing its numbers of front line cells (neutrophils). When you are feeling a little under the weather, not quite sick yet, the neutrophils are fighting hard to stop the virus by gobbling up the buds which form on the cell walls. The rate at which your body can increase its numbers of immune vs the number of times a virus can replicate itself will determine whether you get sick or not.
If you get sick the immune system brings in other ranks of cells like the killer cells and the monocytes . Killer cells are the big guns of your army and the monocytes clean up what is left behind. So what role does a temperature play in this process? Most viruses can only survive at around 37degC ( body temperature) so the immune system triggers the body to generate more energy to raise its core temperature. This resetting of the thermostat, can result in chills and fevers. The chill occurs after the body has raised the temperature to fight the virus and then it needs to lower it back to normal as a protective mechanism.
The body controls its temperature quite closely because too much heat can cause adverse affects in the brain. It is these potential adverse effects that pharmaceutical companies play on when advertising their fever relief products. It is rare for a fever to develop into something more in children, even those who have suffered fever induced fits have no adverse affects (besides scaring their parents). If the fever is suppressed then the immune system has to work a lot harder to fight the virus, which is why these viruses tend to linger rather than resolve themselves in a few days.
As mentioned it is important that you feed your army well and look after it. Two of the key nutrients required for a healthy immune system are Vitamin C and Zinc. High dosing both of these nutrients if you first notice signs of illness can often provide enough nutrients to you front line defence immune cells so they can overcome the virus before you get sick.
Vitamin D is also essential for a healthy immune system, so aim to get at least 10 minutes of unprotected sun exposure in the middle of the day. There are also some herbs which are great to support the immune system – Echinacea, Andrographis, Olive leaf, Astragalus plus Pelargonium.
Some simple things if you feel you or your child are getting sick:
- reduce your stress, get plenty of rest and relaxation
- avoid processed sugary foods, avoid all dairy foods and minimal wheat foods
- increase water intake, you should be drinking at least 2+ litres/ day
- eat easy to digest foods such as soups
- avoid alcohol
- adequate levels of Vitamin C and Zinc
So if your child has a healthy immune system they don’t need anything to manage a fever, the body knows exactly what it is doing. Keep you child quite and well hydrated and they will recover with a strong immune system intact.
