According to the Daily Mail, changing the clocks twice a year for British Summer Time increases the risk of a heart attack due to stress and sleep deprivation.
Sleep deprivation, increased stress and changes in daily routine could be behind the rise, believe researchers, who studied data from Brazil.
‘The effect is quite large compared to other factors that affect heart-attack risk,’ say the experts from Mato Grosso university in Brazil and Bologna university in Italy.
Other research has linked the disturbance caused by changing clocks to increases in fatal car crashes, sleep problems and other health issues.
During British Summer Time (BST) the time advances an hour to allow for extra daylight in the evenings.
The idea was first proposed by George Vernon Hudson, an English-born insect specialist and astronomer, in 1895.
