Japan Fights Sleep Crisis: New Medical Depts Open
2 Apr
Summary
- New medical departments for sleep disorders are opening nationwide.
- Japanese adults report some of the shortest sleep durations globally.
- Lack of sleep causes significant economic losses, estimated at 3% GDP.
New medical departments focused on sleep disorders are set to launch across Japan, marking the first such departmental specialty addition in 18 years. This move aims to facilitate easier access to care for individuals struggling with sleep problems. The causes of sleep disorders are diverse, with severe daytime drowsiness potentially indicating sleep apnea and insomnia possibly linked to depression.
Despite these advancements, concerns persist regarding the insufficient number of specialists and regional disparities in care. There are worries about misdiagnoses and the over-prescription of sleeping pills. The Japanese Society of Sleep Research is initiating training programs and promoting collaboration with specialized hospitals to foster expertise.
Sleep deprivation poses serious health risks, including obesity, high blood pressure, diabetes, and heart disease. Japanese people report the shortest sleep durations among surveyed OECD countries. Nearly 40% of adults sleep less than six hours nightly, with one in five feeling unrested.
Societal factors, such as valuing work over sleep and increased smartphone use before bed, contribute to this deficit. Insufficient sleep impairs work efficiency, academic performance, and can lead to accidents, resulting in economic losses estimated at 3% of Japan's GDP. Recommended sleep durations are six to eight hours for adults and nine to 12 hours for elementary students.
