Light offers a non-invasive alternative to painkillers in veterinary medicine‎

Turning on the light to turn off pain: This is the principle behind a new analgesic method called light-induced analgesia (LIA), discovered by scientists from the CNRS1 in rodents. Noninvasive and drug-free, LIA proves to be more effective and longer-lasting than commonly used analgesics such as ibuprofen. The study was published in Nature Communications on 26 January 2026.
