HEALTH NOTES: Random smiles ‘boost mood’ researcher claim
Walking past a smiling stranger makes you more confident, new research suggests. More than two thirds of Britons report a boost to their self esteem after coming into contact with a smiling stranger, according to a YouGov poll.
Past US research has shown that even forcing a smile can trigger the cascade of chemicals released when we’re happy – such as dopamine and serotonin.
Psychologist Dr Carlos Crivelli who was involved with the poll commissioned by Specsavers, said Covid restrictions – such as lockdowns and social distancing – are limiting this important mood-boosting tool.

Yogurt bacteria boosts repair of broken bones
Healthy bacteria found in natural yogurt could help fractured bones heal faster.
Scientists from Hubei University in China found that coating a metal implant – used to realign broken bones – in the bacterium Lactobacillus casei nearly doubled the speed at which the bone tissue regrew.
The research was carried out on rats with broken tibias – the bone between the leg and the ankle – treated with titanium implants.
Those given bacteria-coated implants saw bone tissue increase by roughly 30 per cent, compared with 16 per cent in a group treated with non-coated metal implants.
It is thought that the bacteria’s immune- boosting power helps to promote faster tissue generation.

Fear of catching Covid at the GP surgery is stopping half of Britons from seeking help for deadly liver cancer – slashing their chances of survival.
Experts say acting quickly after noticing the tell-tale signs – swollen stomach, loss of appetite and nausea – is crucial, as the disease often sets in years before symptoms develop. The condition, which kills 15 British each day, is too often diagnosed at late stages when the cancer has spread.
A YouGov poll, commissioned by the British Liver Trust, also found half of Britons weren’t aware that being overweight and having the hepatitis virus increased the risk of liver cancer.
A quarter of British households are at loggerheads over Covid-etiquette, according to a nationwide poll.
A tenth of respondents said they no longer talked to friends or family members due to their inappropriate behaviour during the pandemic.
On a more positive note, despite the tensions with immediate family, a third of Britons felt closer to their community since the start of the pandemic, according to the poll by King’s College London.
