An important new study confirms there is a genetic link between insomnia and heart disease, reports Fox 11.

“Insomnia is waking up in the middle of the night and having trouble sleeping for an extended period of time,” Khandwalla told Good Day LA.

And, according to Khandwalla, insomnia can be caused by a variety of reasons and can affect people of all ages, although insomnia increases in incidence as people get older. Prolonged insomnia, Khandwalla said, can lead to a variety of different health conditions, including depression, hypertension and heart disease.
