Men Think More Clearly If They Sleep Alone

The BBC reports on research suggesting that men who want to be at their mental best should sleep alone. Professor Gerhard Kloesch and colleagues at the University of Vienna studied eight unmarried, childless couples in their 20s. Each couple was asked to spend 10 nights sleeping together and 10 apart while the scientists assessed their rest patterns
with questionnaires and wrist activity monitors. The next day, the BBC reports, the couples were asked to perform simple cognitive tests and had their stress hormone levels checked. Although the men reported they had slept better with a partner, they fared worse in the tests, with their results suggesting
they actually had more disturbed sleep. Read more at BBC.
