What is Asthma

Millions of people all over the world suffer from Asthma and allergy related symptoms. Asthma and allergy effects can range considerably in their scale of severity. Asthma and allergy in children is common and many people will know about asthma and what asthma is through knowing someone with allergy or asthma. Many people have asthma and allergies as a young child and grow out of them but recent studies over the last 12 years have found that an increasing number of people are developing asthma or allergies in later life and living with it for longer. Unfortunately, there is a lack of solid scientific evidence to explain this increase in the instances of asthma and allergies, although if you have a look around you'll see plenty of theories being forward including; stress and anxiety conditions; global warming and pollution; chemicals used in food production etc...the list goes on.

Asthma and Allergies

What we do know about asthma and allergies is that it seems that there are certain triggers that can antagonise the symptoms of asthma and allergies. Not all of these triggers affect all asthma and allergy sufferers and some affect some people more than others. One of the most common triggers, and one that can be prevented or at least significantly reduced is mould. There are a number of places around the home where there is a risk of mould growing. You can follow some simple steps to prevent this such as by having your home well insulated and ensuring that 'wet' areas such as the laundry room and bathroom are well ventilated. Another proactive step that can be taken to reduce the chances of antagonising the effects of asthma and allergies, one which involves making a small investment, is to use a dehumidifier in the home.

What is a Dehumidifier and How does it help Asthma and Allergy Sufferers

The purpose of a dehumidifier is not to get rid of mould per se, but rather to combat the conditions that allow mould to form. Mould forms as a result of damp or humid air within your house. The moisture in the air will attach itself to a cold surface creating mould and fungal spores. These spores are a nightmare for anyone who suffers from allergies or asthma as it can really worsen the effects. Common spots for mould spores to develop in include shower basins, cold pipes and around windows (especially windows that aren't properly insulated). It's an unfortunate situation because it's generally regarded that asthma and allergy sufferers who breathe moist, humid air will notice an improvement in their breathing. However, this same moist, humid air will eventually lead to mould which is widely accepted as being a key trigger in worsening asthmatic conditions.

Many people don't know about dehumidifiers or what they are used for, but some people argue that they can be used in the treatment of asthma and allergies. What a dehumidifier does is remove some of the moisture floating around in the air. Instead of the moisture falling onto a cold surface to create mould and fungal spores, that are bad for asthma and allergy, it is captured by the dehumidifier. All of the moisture captured by the dehumidifier is caught in a receptacle that you should empty once the cycle has finished.

A dehumidifier won't cure asthma or allergies and shouldn't be used as a substitute for professional asthma treatment as prescribed by a doctor or nurse. People often ask how to cure asthma or bronchial asthma and allergies but at present there is no asthma or allergy cure. There are, however, many ways in which the condition can be managed and therefore reduce the chances of an asthma attack.

Checking Humidity Levels in your Home

Checking your humidity levels is easy once you understand a little about the science behind it. The humidity in the air is measured using a scale called Relative Humidity (RH) which is based on the percentage of moisture being held in the air. When the air is holding all the moisture that it possibly can then the RH will be 100. When the RH level goes above 100 then it means that the air is literally over-flowing with moisture. So, the moisture leaves the air and attaches itself to a solid surface in the form of condensation. If you regularly get condensation on the windows in your home then it may mean that the air in your house is too humid and you're at risk of developing mould and fungal spores which is bad for your asthma or allergies. You might also notice musty smells around your house and damp walls, especially in the bathroom and the kitchen. These are the symptoms of high humidity that you need to look out for.

What is a Hygrometer

Another way of checking the humidity levels in your home is to use a hygrometer. This is a small inexpensive electronic device (you can also get mechanical versions) that effectively measures the RH level in the air. They're sold at a low price on Amazon but you should be able to find one in your local hardware store or home improvement store.

Take Control of Asthma and Allergies with a Dehumidifier

Unfortunately the scientific evidence to support the use of a dehumidifier to tackle the symptoms of asthma or allergies is limited to non-existent. The theory is all in place and feedback from asthma and allergy sufferers seems to be positive. Certainly, I can confidently say that as an asthma and allergy sufferer who lives in the dampest city in an already damp country I use a dehumidifier as part of a range of measures to keep my asthma and allergies in check and I haven't had any problems for the last several years. Winter can be the most challenging time for an asthma and allergy sufferer as the cold air does us no favours whatsoever, but ensuring there is a right balance of humidity in the air of your home may go some way to reducing symptoms of asthma and allergies.
