Treating insomnia reduces depression symptoms according to new study

Treating insomnia can help reduce symptoms of depression, according to a report from Medical Xpress published on October 12, 2026. Participants in a new research trial reported improvements in both health conditions after receiving sleep treatment. [1]

The study was led by Vanika Lall, clinical associate professor Melissa Ree, and emeritus professor Romola Bucks. The researchers are from The University of Western Australia's School of Psychological Science, and their findings were published in the journal Behaviour Research and Therapy. [1]

Insomnia is a sleep disorder that causes difficulty falling asleep or staying asleep for as long as desired. It is typically followed by daytime sleepiness, low energy, irritability, and a depressed mood, and it can last for days, weeks, or longer. [2]

The medical condition can also lead to an increased risk of accidents alongside problems with focusing and learning. Medical literature divides the condition into two possibilities, which are insomnia disorder and insomnia symptoms. [2]
