working in night shifts, is affecting women's brains more than men's, say experts .The researchers told that the circadian effects — the 24-hour biological cycle — on brain work was stronger in women than in men such that women become restless working in night shifts.

"We show for the first time that challenging the clock affects the performance of men and women in different way. Research findings are significant in view of shift work-related cognitive deficits and changes in mood," said one of the researchers, Nayantara Santhi. The team compared the brain functions of 16 male and 18 female participants, who were kept on 28-hour a day cycle in a controlled environment without natural light dark cycles. This effectively desynchronised the sleep-wake cycle from the brain's 24-hour clock, similar to jet lag or a shiftwork scenario.

The study raises significant impacts for female nightshift workers such as nurses, security guards and police officers.ds and police officers.
