When Arianna Huffington collapsed in 2007, hitting her face on a desk and breaking her cheekbone, sleep deprivation was the last thing on her mind. But then she learned it was lack of sleep that caused her blackout. She knew she had to overhaul her life and make time for the rest she desperately needed.

Her latest book, The Sleep Revolution, calls for a complete cultural overhaul in the way we regard sleep, citing the latest research in sleep science. “Sleep time isn’t empty, it’s a rich time of renewal,” The Huffington Post founder, 66, tells PEOPLE, before explaining how she got a “really good” night’s sleep the evening before.

“I followed my routine of turning off my phone half an hour before bed and moving it outside of my bedroom to charge,” she says. “And then I had my hot bath with Epsom salts and then put on PJs, an actual nightgown. I don’t any longer wear the same clothes I go to the gym in!”

Arianna Huffington Says Fainting In 2007 Was Wake-Up Call

Here are Huffington’s favorite tips for a good night’s sleep:
• Keep your bedroom dark, quiet and cool, between 60 and 67 degrees.
• No caffeine after 2 p.m.
• Shut off your phone half an hour before bed, and move it outside of the bedroom to charge.
• Do some light stretching, deep breathing, yoga or meditation to help your body and mind transition to sleep.
• When reading in bed, choose a book or e-reader that doesn’t emit blue light, and make sure it’s not work-related.
• Ease into sleep mode with chamomile or lavender tea.
• Before bed write a list of what you are grateful for – it’s a great way to make sure your blessings get the closing scene of the night.

Huffington says people seem to finally be paying more attention to the importance of sleep.

“There is a huge cultural shift happening, we have all the science of sleep that makes it so clear that sleep deprivation degrades every aspect of our lives. Our health, our productivity and our happiness,” she says. “It’s almost like how we’ve convinced people of the importance of nutrition and exercise now that we have the information. But the third pillar of health and mental health is sleep.”
