Children's mattresses could be a health hazard after finding out that they are emitting dangerous contaminants that have been associated with cancer.
Exposure to volatile organic compounds (VOC) can be toxic and has been associated with headache, disease, liver and kidney damage, nerve problems and cancer.
The small particles can shoot home when released by hundreds of household items, including furniture, candles, incense and carpets.
Researchers found that materials used to get mattresses release higher amounts of VOC when heated to body temperature.
And they said that people can breathe in "about" the levels of the chemicals when they sleep because their faces are right next to the fabric.

The study did not investigate the possible negative health outcomes of VOC from mattresses.
But in the past, they have been the cause of many studies to trigger childhood asthma and exacerbate it in adults.
Respiration VOC can be irritating to the eyes, nose and throat and cause breathing difficulties.
Scientists at Civil and Environmental Engineering, Technion, the Israel Institute of Technology, used eight different child mattresses in their study.
They measure how the temperature, humidity and carbon dioxide concentration – all of which increases when people lie on a mattress for a couple of hours – can affect the level of more VOC's emitted by the mattresses.
The team led by Dr Yael Dubowski, reported in the journal Environmental Science and Technology that children spend up to half of their lives in this sleep environment.
They did their experiment by placing pieces of the mattresses in a chamber that they were able to take samples of air from.
The eight mattresses released quite similar amounts of 18 examined VOCs, with the exception of a flame retardant compound which was only emitted by an infant mattress.
Temperatures matching body heat were a major contributor to a higher level of VOCs released relative to humidity and carbon dioxide.
Infants and toddlers who inhale some compounds, such as acetaldehyde, formaldehyde and benzene, could be worried, the researchers said.
Another compound with potential health concerns was butylated hydroxytoluene (BHT), detected with great variability between mattresses.
In recent years, there has been a growing concern that the widespread use of BHT, including in food and cosmetics, has carcinogenic potential behind some studies.
However, the results of this study were far below the reference levels for cancer and non-cancer risk.
Exposure to VOC is unavoidable due to the large number of emission sources, including vinyl flooring, cleaning agents, cosmetics, hair sprays, aerosols, heating and cooking.
VOC is built into products and released slowly over months or even years, an example being paints that first have a strong odor that evaporates over time.
Professor Alastair Lewis of the National Center for Atmospheric Science, the University of York, who was not involved in the research, said that most VOCs are harmless.
But there is some evidence VOCs are increasing in the home because airtight homes catch them through lack of ventilation.
He told MailOnline: "If air gets trapped in a home, then there is some potential for self-safe VOCs to be oxidized to more harmful products.
Furniture, such as sofas, Carpets, beds, and so on may take longer to expel, since VOC is buried deeper in the product.
In this study, a thick polyurethane mattress is probably a worst example of something made with VOC because It seems like a large sponge and is slow to release its VOC, but even these over time will lose their VOC.  Professor Lewis said that VOC health risks from mattresses were small but if a parent was Worried, they could instead choose a cotton, wool or spring-based mattress, which would be made with less VCOs.
The researchers said there was a need for further studies on possible health effects of low level VOC exposure Their study was published in magazine t Environmental Science and Technology.
What are volatile organic compounds and what have their effects on health?
Volatile organic compounds (VOCs) are discharged as gases from certain solids or liquids.
VOC contains a number of chemicals, some of which may have short and long term harmful health effects.
Concentrations of many VOCs are consistently higher indoors, up to ten times higher than outdoors.
VOC & # 39; is broadcast by a wide variety of products that are numbered in thousands.
Organic chemicals are widely used as ingredients in household articles.
Paints, varnishes and waxes contain all organic solvents, as well as many cleaning and disinfectants, cosmetic, degreasing and hobby products.
Fuels consist of organic chemicals.
All these products can release organic compounds while using them and to some extent when stored.
The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic to those who have no known health effect.
As with other pollutants, the extent and nature of the health effect will depend on many factors, including the level of exposure and duration of delayed time.
Health effects may include: Eye, nose and throat irritation; headache, loss of coordination and nausea damage to the liver, kidney and central nervous system.
Some organic substances can also cause cancer in animals, and some are suspected or known to cause cancer in humans.
