The secret to successful flirting is letting someone know how you feel

Telling someone you fancy ‘I really like you’ could make him or her find you more attractive, research suggests.

Making eye contact and smiling have a similar effect, says Aberdeen University psychologist Dr Ben Jones.

His study, involving 230 men and women, found such social cues – which signal how much others fancy you – play a crucial role in attraction.

The work will appear in Psychological Science and will be presented at the BA Festival of Science in Liverpool.

Romantic success

Dr Jones said singletons could use his findings to help prevent wasting time chatting up people who were clearly not interested.

“Combining information about others’ physical beauty with information about how attracted they appear to be to you allows you to allocate your social effort efficiently,” he said.

In other words, avoid wasting time on attractive individuals who appear unlikely to reciprocate.

Maybe one of the ways you learn your level of attractiveness is through how other people behave towards you

In the study, 230 men and women were asked to look at flash cards picturing a face with different expressions – making eye contact or not and smiling or not.

The volunteers were then asked to rate how attractive the faces were.

The preference for the attractive face was much stronger when people were judging those faces that were looking at them and smiling.

Dr Lynda Boothroyd, a psychologist at the University of Durham, said: “We like it when attractive people seem to be behaving positively towards us.

“And we seem to end up with people who are on our level in terms of attractiveness.

“Maybe one of the ways you learn your level of attractiveness is through how other people behave towards you.”

Vein tubes ‘fitted needlessly’

Vein tubes ‘fitted needlessly’

Cannula being inserted in order to take blood

Cannulas are used to help take blood and to give drugs and fluids

A third of patients have unnecessary tubes inserted into veins when they are in hospital, pharmacists have warned.

Researchers from Aberdeen’s Robert Gordon University said this needlessly exposed them to serious complications, such as infections and blood clots.

Just under 350 patients were studied over six weeks, the majority of whom had the tubes, called cannulas, fitted.

An A&E expert recognized cannulas should be used less frequently and for shorter periods.

It’s entirely reasonable to look at their use

The study was presented to the British Pharmaceutical Conference in Manchester.

Cannulas – hollow plastic tubes with a needle at the tip which cost around £1.70 each – are used to give medication and fluids to people who cannot swallow because they are unconscious or being given nil by mouth, and it has been estimated that around 80% of hospital patients have them fitted.

Drugs may also be more easily absorbed if given this way.

But potential complications include problems with veins (phlebitis), drugs leaking into tissues around the site of the tube, serious infection and blood clots.

‘Common practice’

Of the patients studied – who were all treated in the acute medical assessment unit of Aberdeen Royal Infirmary, 91% of patients had a cannula inserted. But 28% of the tubes were never used.

The researchers also found that in 71% of patient records there was no documentation of a cannula being inserted, while in 57% there was no documentation of it being removed.

Four patients had developed blood poisoning, which infection control specialists said was likely to be linked to the cannula.

The researchers, led by Dr Yash Kumarasamy, said that in many UK hospitals, it has become common practice to insert an intravenous cannula when the patient is admitted, irrespective of need.

He said: “We would like to see the introduction of a formal procedure under which hospital pharmacists review patients and their medications and make recommendations to the treatment team about whether or not a cannula is needed.”

Dr Martin Shalley, a former president of the British Association of Emergency Medicine, agreed there had been an over-reliance on cannula use.

He said many trusts had policies saying cannulas had to be removed after 72 hours

“It used to be a knee-jerk response to insert a cannula – but we now recognise there’s a need to think if fitting one is a benefit for that patient.

“It’s entirely reasonable to look at their use. That’s the case in A&E medicine and across acute medicine too.”

And Dr Shalley said he thought the level of use of cannulas had increased the level of hospital-acquired infections such as MRSA.
