Health Effects of Prolonged Mould and Asbestos Exposure

Mould and asbestos removal protect against silent threats lurking in the very structures supposed to provide comfort and shelter. Without prompt and adequate action, their insidious character, along with the possibility of severe health implications, can have disastrous results for homeowners. 


This blog delves into the critical features of asbestos exposure, putting light on the potential health risks it poses.

Health Effects of Mould Exposure

Respiratory Issues

Mould spores can irritate the airways and cause allergic responses in people who are sensitive to them. This inflammation can cause coughing, wheezing, and worsening of pre-existing asthma symptoms. Prolonged exposure can cause chronic respiratory problems that make breathing difficult.

Skin and Eye Irritation

Skin irritation can develop from direct contact with mould or its spores, resulting in rashes, redness, or itching. Similarly, inhaling mould particles might cause eye discomfort or redness.

Allergic Reactions

Mould exposure can cause severe allergic responses in persons who have allergies or impaired immune systems. This exposure might result in sinus infections or fungal infections in the lungs, especially in people with compromised immune systems.

Toxic Effects

Some mould species create mycotoxins, which are toxic chemicals. These mycotoxins have the potential to create more serious health problems if swallowed, breathed, or come into contact with the skin. However, the precise impact of these poisons on human health is still being researched, and their effects might differ greatly across individuals.

While not all moulds create mycotoxins, all mould development indoors, regardless of species, should be handled and eradicated as soon as possible to reduce health hazards. Failure to do so might lead to severe mould-related illnesses. Those with respiratory disorders, allergies, or weakened immune systems are more prone to the negative effects of mould contact and should take extra steps to prevent their exposure. A healthy indoor environment requires regular inspection, upkeep, and effective repair of mould-infested areas.

Health Effects of Asbestos Exposure

Respiratory Problems

Inhaling asbestos fibres can cause asbestosis. Once breathed, these minute fibres can induce scarring and inflammation in lung tissue. Scarring may grow widespread over time, decreasing lung function and making it increasingly difficult to breathe. Asbestosis is a chronic and irreversible lung illness that can lead to respiratory failure and impair an individual’s capacity to perform everyday tasks.

Lung Cancer

Asbestos exposure dramatically raises the chance of acquiring lung cancer. Individuals who are both exposed to asbestos and use tobacco are at a significantly increased risk. The combination of smoking and asbestos exposure considerably increases the risk of getting lung cancer, making it a particularly deadly combo.


Mesothelioma is one of the most serious health hazards connected with asbestos exposure. This deadly cancer typically affects the thin lining of the lungs (pleura), but it can also attack the lining of the belly (peritoneum) or the heart (pericardium). Mesothelioma has an unusually lengthy latency period, with symptoms commonly manifesting 20 to 50 years after initial asbestos exposure. Unfortunately, it is frequently identified at an advanced stage, making treatment difficult and the prognosis bad.

Other Cancers

Asbestos exposure has been associated with a variety of cancers, including those of the larynx, ovaries, and other organs, in addition to lung cancer and mesothelioma. These malignancies, while not as directly linked to asbestos exposure as lung-related disorders, are nevertheless associated with persistent exposure to asbestos fibres.


The insidious trait of most asbestos-related disorders is their latency period; symptoms may not appear until decades after exposure, making diagnosis and treatment difficult. Prevention and early identification are critical in managing these health hazards, highlighting the significance of avoiding asbestos-containing products and getting medical help if there is a history of exposure or symptoms.
