The claimed benefit in the article is for depression. Depressed people who suffer sleep deprivation sometimes become less depressed. That could be true at the same time that cognitive performance and/or health suffers. I don’t know how long the sleep deprivation benefit works for depression, but just something to keep in mind; less sleep (or more sleep) is not necessarily a binary good or bad thing, it can be multiple goods and bads in some unknown weighted combination, and it can change over time and according to context, i.e., short term deprivation might help some people while long term deprivation does lasting damage.
