Richardson has determined that a common household fungus, Scopulariopsis brevicaulis, gets established in the mattress from the baby's sweating, spitting up and so on. Once established, the fungus begins to consume these three chemicals in the mattress. This results in the production of three nerve gasses: phosphine, arsine and stibine, all of which can be very deadly, especially to infants. In late 1988 Richardson asked local coroners to cooperate by releasing mattresses on which SIDS babies had died. He received 200 mattresses of all varieties: foam, plastic, fabric and netted. By June 1989 all mattresses had been tested with the following results: At this time, Richardson analyzed six blood samples of the SIDS babies who died on mattresses with antimony and found high levels of antimony in each sample. In addition, Richardson learned that 95 percent of mattresses tested had been used by a previous baby. Meanwhile, a New Zealand chemist, T.J. Sprott, was questioning the role of chemicals in the baby's environment.
He learned of Richardson's research and concurred that nerve gas could also be poisoning babies in New Zealand. He established the guidelines for wrapping mattresses, known as the Cotlife 2000 Specifications. (For additional information, log on to www.cotlife2000.co.nz.) These specifications involved wrapping the baby's mattress with a gas impermeable plastic to keep the gasses from contaminating the sleeping area and, in addition, using cotton bedding. Since 1996, New Zealand has wrapped 100,000 baby mattresses to these specifications. There have been no reported deaths to date on these wrapped mattresses. SIDS is called the "mystery disease." Understanding the gas theory explains away the mystery by answering all of the following perplexing questions: Q: Why do SIDS babies show no symptoms? A: The lethal dose of nerve gas doesn't make them "ill." It acts by shutting down the nervous system, stopping heart function and breathing. Research has shown neurochemical deficits in SIDS babies that are consistent with poisoning by nerve gas.
Q: Why are babies at higher risk after illness or vaccination? A: The fever that results increases the temperature in the crib environment. This stimulates fungus activity and nerve gas production tenfold or more. Q: Why does the rate of crib death rise from one sibling to the next? A: In a reused mattress, fungus established in prior use cause toxic gas generation to commence sooner and in greater volume. Q: Why are babies at higher risk in families where births are close together? A: Once again, the fungus in the mattress from the previous use will be quickly activated, producing gas sooner. Q: Why are SIDS rates higher in the winter? A: Windows are kept shut, creating poor ventilation around the crib. Gasses are less likely to dissipate. Babies are often bundled in blankets during the winter, trapping gasses close to their bodies. Q: Why are babies sleeping face down at higher risk? A: Stibine gas is formed from the interaction of the S. Brevicaulis fungus and the antimony in the mattress.
This gas is very heavy and hangs right on the surface of the mattress. A baby sleeping face down will breathe this gas directly and is more likely to inhale a lethal dose. Q: Why are boy babies at higher risk for SIDS? A: Most boys have a higher metabolic rate than girls, thus their body temperature can be somewhat higher than girls. The rate of gas generation increases rapidly with increasing temperature. Q: Why does SIDS sometimes occur during bed-sharing on an adult mattress? A: Phosphorus, arsenic or antimony can be found in most mattresses, allowing the generation of the nerve gasses. Adults are not as susceptible to gas poisoning as infants. Q: Why was SIDS rare before 1950? A: Prior to 1950, harmful chemicals were not added to mattresses. It was postwar technology that prompted the common use of phosphorus as a plasticizer, arsenic as a preservative and antimony as a fire retardant. In England and Wales the SIDS statistics from 1953 onward increased in parallel with the increasing concentration of antimony in mattress covers.
In addition, prior to 1950 people commonly used soap for baby laundry, whereas now detergent and fabric softeners are commonplace. Detergent contains nitrogen and phosphorus compounds on which the fungus feeds. Q: Why does SIDS generally occur between the ages of 2 months and 1 year? A: It takes time for the fungus in the mattress to flourish and start generating gas. However, younger babies can die if they are sleeping on a mattress that has recently been used by an older sibling and has established, flourishing fungus. As babies get older, the gas exposure gives them a headache causing them to move around, wake their parents and stand up in their crib. Q: Why is SIDS non-existent in some other countries? A: There used to be virtually no crib deaths in Japan. Japanese traditionally used untreated cotton futons for babies. Recently, Japan has started to adopt Western baby care practices, mattresses, etc., and the crib death rate has begun to rise. SIDS is practically non-existent in Russia, as well.
There, it is common place to cover the mattress with rubber sheeting. This rubber is gas impermeable, inhibits fungal growth and is free of phosphorus, arsenic and antimony. Q: Why have SIDS rates fallen over the past five years, but are now leveling out? A: Five years ago the Back to Sleep campaign was introduced encouraging parents to position their babies on their backs. This has likely saved many babies from stibine (the gas from antimony) poisoning. As was said earlier, this gas is heavy and hangs right on the surface of the mattress where face-down babies breathe it directly. However, babies sleeping on their backs are still exposed to the lighter nerve gasses: arsine and phosphine. In a warm environment phosphine can be similar to the density of air, and easily inhaled by a baby sleeping on its back. In addition, face-up sleeping is not as effective in a cot or bassinet with enclosed sides, because the gasses cannot flow away. To prevent these nerve gasses from reaching the baby, New Zealand CotLife2000 Specifications recommend doing all of the following:
