Insomnia increases cardiovascular risk
Experts have emphasised on sleep being an important factor to help the body rejuvenate and recover every day. A new study indicates that insomnia can heighten the risk of cardiovascular diseases or CVDs.

The study indicated insomnia can raise the risk of CVDs by 16 per cent. It analysed just over 1,000 people with an average age of 62 years old, who had all experienced a heart attack or a procedure to open blocked arteries in the past (average of) 16 months. The participants filled out a questionnaire on energy levels, their ability to fall asleep and stay asleep, etc., while data on other risk factors for heart health were collected from their medical records. All participants were tracked for an average of just over four years, to see if/when any major adverse cardiovascular events (MACE) occurred, such as stroke, heart failure, or cardiovascular death.

The study found nearly half of the participants had insomnia at the start of the study, and 24 per cent had used sleep medication recently. During the follow-up period, 364 MACE had occurred in 225 of the participants, according to the study. This means that 16 per cent of recurrent major adverse cardiovascular events might have been avoided if none of the participants had insomnia.
