PFAS, known as “forever chemicals,” have been linked to poor sleep quality, according to researchers at the University of Southern California. The study looked at blood samples and sleep habits of more than 140 young adults, ages 19 to 24. Results showed that higher levels of four specific PFAS chemicals — PFDA, PFHxS, PFOA, and PFOS — were linked to sleep problems. Participants with the most exposure to these chemicals slept up to 1 hour and 20 minutes less each night compared to those with lower levels.

PFAS chemicals remain in the environment for a long time and are commonly found in everyday items like nonstick cookware and shampoos. Most Americans have detectable levels of these chemicals in their blood, raising health concerns. The study showed that high levels of one type, PFOS, were especially linked to difficulties falling asleep, staying asleep and feeling tired during the day. Poor sleep is important to address, as it can lead to long-term health issues, including memory problems, type 2 diabetes and Alzheimer’s disease.

The USC team also examined how PFAS chemicals affect genes linked to sleep. They identified seven genes influenced by these chemicals that might impact sleep patterns. One of these genes helps produce cortisol, a hormone that regulates sleep cycles, while another, Cathepsin B, is related to memory and brain health, including Alzheimer’s. The findings suggest that exposure to PFAS from an early age, possibly even before birth, could have long-term effects on sleep and overall health.
