Sound wave therapy can improve sleep and memory, according to a new study fromNorthwestern Medicine in the US.
According to Psych Central, Neuroscience graduate student Nelly Papalambros wanted to find out if there was a non-invasive way to improve sleep quality, because of its many effects on health. Poor sleep has been linked to everything from cognitive problems (including memory issues and difficulty concentrating) to heart attack and disease, while insomnia drastically increases the risk of accident and injury.
Papalambros recruited study participants with an increased risk of heart disease, and measured their baseline stats and sleep patterns while they stayed at a sleep research centre overnight. She then tested whether playing a low-grade static noise could improve their quality of sleep. This sound was developed by Giovanni Santostasi and is personalised in order to be more effective.
