How scientists changed their view of insomnia
Scientists have made significant progress in understanding chronic sleep deprivation over the last 20 years, recognizing that insomnia is often an independent disorder requiring its own treatment. Research has shown that addressing sleeping problems can lead to improvements in other health conditions such as chronic pain, depression, and PTSD.
Insomnia affects a significant portion of the adult population in England, with about a third reporting frequent symptoms. Initially, insomnia coupled with another illness was considered secondary and not treated directly. However, by the early 2000s, research indicated that this approach was incorrect, as insomnia could precede or outlast primary conditions. It is now recognized as an independent disorder requiring treatment. Women, older individuals, and those of lower socio-economic status are more vulnerable to insomnia due to various biological, psychological, and social risk factors. Treating insomnia has been shown to improve other health conditions such as chronic pain, depression, and PTSD.
