Can you get asthma from second hand smoke?

User Avatar

Asked by Wiki User

Yes you can. My girlfriend got her asthma because her mother was always smoking around her. Her mother doesn't smoke any more, but my girlfriend will use her inhalor three to four times a day. No. Asthma is not "caused by" smoke, animal dander, pollen, etc. Those things may trigger an attack, but they are not the reason you have the condition. Yes and no. Asthma is hereditary in the way that some people are more likely to get it than others. Second hand smoke is both a trigger for an attack AND a factor that can lead to asthma, especially in young children. Asthma can be 'caused' by certain triggers, but that depends on your family history.

No you cant get asthma from second hand smoke. There are over 40,000 triggers for asthma and has been found in children is being around passive smoke lowers incidences of asthma and heres why.

The inconvenient truth is that the only studies of children of smokers suggest it is PROTECTIVE in contracting atopy in the first place. The New Zealand study says by a staggering factor of 82%.

"Participants with atopic parents were also less likely to have positive SPTs between ages 13 and 32 years if they smoked themselves (OR=0.18), and this reduction in risk remained significant after adjusting for confounders.

The authors write: "We found that children who were exposed to parental smoking and those who took up cigarette smoking themselves had a lower incidence of atopy to a range of common inhaled allergens.

"These associations were found only in those with a parental history of asthma or hay fever."

They conclude: Our findings suggest that preventing allergic sensitization is not one of them."

This is a Swedish study.

"Children of mothers who smoked at least 15 cigarettes a day tended to have lower odds for suffering from allergic rhino-conjunctivitis, allergic asthma, atopic eczema and food allergy, compared to children of mothers who had never smoked (ORs 0.6-0.7)

CONCLUSIONS: This study demonstrates an association between current exposure to tobacco smoke and a low risk for atopic disorders in smokers themselves and a similar tendency in their children."

In 2008 this paper was produced in America and concludes that nictotine and hence active smoking and passive smoking leads to less asthma. It also gives the aetiology (causation) why nicotine and the biologial process that reduces asthma in recipients.

The results unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE. unequivocally show that, even after multiple allergen sensitizations, nicotine dramatically suppresses inflammatory/allergic parameters in the lung including the following: eosinophilic/lymphocytic emigration; mRNA and/or protein expression of the Th2 cytokines/chemokines IL-4, IL-5, IL-13, IL-25, and eotaxin; leukotriene C4; and total as well as allergen-specific IgE.

Why is there more people with asthma now than in the past?

User Avatar

Asked by Wiki User

There are several factors contributing to the rise in asthma cases, including increased air pollution, exposure to allergens, changes in diet, and lifestyle factors such as decreased physical activity and increased stress levels. Additionally, better awareness and diagnosis of asthma may also play a role in the increasing number of reported cases.

How is asthma related to climate change?

User Avatar

Asked by Wiki User

Climate change can worsen asthma symptoms by increasing air pollution, such as smog and pollen, which can trigger asthma attacks. In addition, extreme weather events linked to climate change, like heatwaves and wildfires, can also exacerbate asthma symptoms and lead to more emergency department visits.

What is a respiratory disease in which airways in the lungs become narrow because of sensitivity to certain stimuli?

User Avatar

Asked by Wiki User

Asthma is a respiratory disease characterized by inflammation and narrowing of the airways in the lungs, making breathing difficult. This narrowing can be triggered by various stimuli such as allergens, pollutants, and exercise. Symptoms include wheezing, coughing, chest tightness, and shortness of breath.

Is sweating during sleep okay?

User Avatar

Asked by Wiki User

Sweating during sleep is normal and usually not a cause for concern. It can be triggered by the room being too warm, certain medications, or hormonal changes. However, if excessive sweating during sleep is accompanied by other symptoms like fever, weight loss, or night sweats, it may be worth seeing a healthcare provider to rule out underlying medical conditions.

How does proteins work?

User Avatar

Asked by Wiki User

Proteins are complex molecules made up of amino acids that play many critical roles in the body, including providing structure to cells and tissues, facilitating chemical reactions, and serving as signaling molecules. Proteins work through their unique three-dimensional shapes, which allow them to interact with other molecules in specific ways to carry out their functions. Additionally, proteins can be modified through processes like phosphorylation to regulate their activity.

Are all mutations dominant?

User Avatar

Asked by Wiki User

No, not all mutations are dominant. Mutations can be dominant, recessive, or have incomplete dominance depending on how they affect the resulting trait and how they interact with other genes in the organism. Dominant mutations are expressed even if there is only one copy of the mutated gene, while recessive mutations require two copies to be expressed.

Can asthmatics donate organs?

User Avatar

Asked by Wiki User

In general, individuals with well-controlled asthma may be eligible to donate organs. However, each case is evaluated individually based on factors such as the severity of the asthma, organ function, and overall health of the donor. It is important to consult with healthcare providers and transplant professionals for guidance on organ donation eligibility.

How does Perfume effect ozone and health?

User Avatar

Asked by Wiki User

Perfume can release volatile organic compounds (VOCs) into the air, and when these VOCs react with sunlight and other chemicals, they can contribute to the formation of ground-level ozone. Ozone is a harmful air pollutant that can worsen respiratory conditions, trigger asthma attacks, and cause other health issues. It's best to use perfumes sparingly and in well-ventilated areas to minimize their impact on air quality and health.

Why is it that in very cold climates indoor relative humidity can be low while the outside relative humidity can be high?

User Avatar

Asked by Wiki User

In very cold climates, the air holds less moisture because cold air has a lower capacity to hold water vapor compared to warm air. When cold air is warmed indoors, its relative humidity drops because the same amount of water vapor is now distributed among a larger volume of air. However, the outside air remains humid because it hasn't been warmed yet.

Are ozone air filtration systems bad for your health?

Theophylline is a medication used to treat asthma and other lung conditions by relaxing the muscles in the airways and decreasing inflammation. It helps improve breathing by opening up the air passages in the lungs.

What is in inhalers?

User Avatar

Asked by Wiki User

Inhalers typically contain a medication (such as bronchodilators or corticosteroids) in a liquid, powder, or aerosol form. The medication is designed to be delivered directly to the lungs through inhalation to treat respiratory conditions like asthma or COPD. Some inhalers may also contain propellants to help deliver the medication effectively.

What is the pathogen causes Asthma?

It is a chronic inflammatory condition of the airways that can be triggered by various factors such as allergens, pollution, respiratory infections, and genetic factors. Infections with certain viruses, such as rhinovirus and respiratory syncytial virus, can exacerbate asthma symptoms in some individuals.

Is keeping the heat on at night bad for your health?

User Avatar

Asked by Wiki User

Keeping the heat on at night is generally not bad for your health, as long as the room is well-ventilated and the temperature is not too high. However, excessively high temperatures or poor ventilation can lead to issues like dehydration, dry skin, or respiratory problems. It's important to find a comfortable temperature that allows for restful sleep without overheating.

What is dominant negative mutation?

User Avatar

Asked by Wiki User

A dominant negative mutation occurs when a mutant protein interferes with the function of the normal protein produced by the other allele, resulting in a loss of function phenotype. This typically happens in genes that encode multimeric proteins where the mutant protein can disrupt the function of the wild-type protein.

How might smoking affect tidal volume?

User Avatar

Asked by Wiki User

Smoking can lead to inflammation and narrowing of the airways, decreasing air flow and causing the lungs to work harder to take in oxygen. This can result in a decrease in tidal volume, which is the amount of air that moves in and out of the lungs during normal breathing. Additionally, smoking can also damage lung tissue and reduce the overall lung function, further impacting tidal volume.
