New Delhi, Oct 26: Being exposed to bright light at night, including scrolling through one\u2019s phone, could be related with a 56 per cent higher risk of heart failure, and can be a significant risk factor for cardiovascular diseases among adults aged 40 and above, according to a new study.
\nResearchers led by those at Australia\u2019s Flinders University analysed more than 13 million hours of light exposure data collected through sensors that nearly 89,000 people in the UK wore on their wrist. The participants were followed up for more than nine years.
\nExposure to light at night was also linked with a 47 per cent higher risk of a heart attack, 32 per cent of coronary artery disease and 28 per cent of stroke.
\n\u201cNight light exposure was a significant risk factor for developing cardiovascular diseases among adults older than 40 years,\u201d authors wrote in the study published in the Journal of the American Medical Association (JAMA) Network Open.
\nLead author Daniel Windred, research associate at Flinders University, said, \u201cThis is the first large-scale study to show that simply being exposed to light at night is a strong and independent risk factor for heart disease.\u201d \u201cDisrupting your body\u2019s internal circadian clock by repeatedly exposing yourself to bright light at night, when it would typically be dark otherwise, will put you at a higher risk of developing dangerous heart issues,\u201d Windred said.
\nThe study also found that women and younger people were especially vulnerable to the impact of light exposure at night.
\n\u201cWomen may be more sensitive to the effects of light disrupting their body clock, which supports earlier research findings,\u201d senior co-author Sean Cain, professor at Flinders University\u2019s college of medicine and public health, said.
\n\u201cIn fact, women exposed to high levels of night light had similar heart failure risks to men, which is unusual because women typically have some natural protection against heart disease,\u201d Cain said.
\nThe researchers suggested avoiding light at night may be a useful strategy for reducing risks of cardiovascular diseases.
\nUsing blackout curtains, dimming lights, and avoiding screens before bed could help address health risks related with being exposed to light at night, they said.<\/p>\n
