Women look their oldest at 3.30pm every Wednesday, a study has found, because that is when energy levels plummet, work stress is at a peak and the effects of any weekend late nights finally kick in.

The research shows one in ten women find Wednesday the most stressful day in a typical week.

But they reveal Thursday is the day they are most likely to have sex.

It gives them a youthful rosy glow which could contribute to why women feel so happy on a Friday – which 60% claim it as their happiest day.

The study, carried out by the tanning brand, St Tropez, revealed two thirds experience a "slump in energy levels" mid-afternoon every Wednesday.
