Will poor sleep result in heart attack? Renowned cardiologist explains

Stressful jobs, late doom scrolling, partying, late-night chats... we have umpteen reasons to let our time creep into our sleep schedule. According to Harvard Health, some people need less than seven hours, but others need more and what matters more is the quality of our sleep than the hours. Sleep quality is key to our overall health as well, as those with poor sleep are at a higher risk for heart diseases, mental health, depression, diabetes and more. Dr Joby K Thomas, Senior Consultant and Interventional Cardiologist at Caritas Hospital, Kottayam, explains why poor sleep can lead to cardiac issues. 

It's our resting time
Our sleep time is when our bodies rest and recover. "Hormones like cortisol, norepinephrine and adrenaline, which are called stress hormones, also control our blood pressure and sugar. If we don't sleep well enough, these stress hormones can increase in our bodies. This can result in worsening our diabetes and blood pressure. This can, in turn, increase the possibility of a heart attack," the doctor explains. 

How to improve your sleep hygiene
The Harvard Medical School offers a few tips to establish a sleep hygiene for better health:
1) Take steps to mask noice, the maximum, with heavy curtains.
2) Block lights, ensure outside lights aren't shining into your room, with thick curtains.
3) Keep the room temperature comfortable for your body.
4) Keep devices and work-related gadgets outside the room

5) Make sure your pillows and mattresses are clean and comfortable.
6) Have your dinner at least three hours before bedtime.
7) Don't have coffee after lunch if it interferes with your sleep.
8) Avoid smoking and alcohol, especially in the evenings, as they can interfere with your sleep quality. 
9) Set up any relaxing bedtime routine, like reading or listening to calm music.
