Daylight Saving Heart Risk

Daylight Saving Heart Risk, It could be the perfect excuse for lying in on Monday morning. Getting up for work after the clocks go forward can be bad for your health, according to scientists.

A team from the University of Alabama were studying the impact of daylight saving on a person’s health.

They found that the abrupt change to a person’s daily schedule increased the risk of having a heart attack by 10 per cent. This impact isn’t felt on the Sunday morning as most people adapt their weekend schedule and rise a little later.

However, the risk peaks on Monday when workers have to get up at a set time to get to the office. When the clocks go back in October the risk of heart attack decreases by 10 per cent.

‘Exactly why this happens is not known but there are several theories,’ said Professor Martin Young.

‘Sleep deprivation, the body’s circadian clock and immune responses all can come into play when considering reasons that changing the time by an hour can be detrimental to someone’s health.’

Everyone in America will need to prepare to lose an hour this Sunday as clocks move forward on March 11. However Britons have longer to prepare as summertime starts two weeks later in the UK with clocks moving forward in the early hours of March 25.

Professor Young said night owls would need to take particular care as they have a more difficult time with ‘springing forward.’

He added: ‘People who are sleep-deprived weigh more and are at an increased risk of developing diabetes or heart disease. Sleep deprivation also can alter other body processes, including inflammatory response, which can contribute to a heart attack.’

Time changes also affect the body’s circadian rhythm, which ‘stresses’ the body cells as they struggle to adjust.

Professor Young said: ‘The internal clocks in each cell can prepare it for stress or a stimulus. When time moves forward, cell clocks are anticipating another hour to sleep that they won’t get, and the negative impact of the stress worsens; it has a much more detrimental effect on the body.’

He added that the immune system can also receive a knock as immune cells also have internal clocks. He pointed to animal studies that found mice given a certain level of toxin died if they had been subjected to a ‘daylight savings time’ effect, but survived if their routine was not changed.
