Naomi Watts has written a new book about menopause

She told PEOPLE: "Women have had to suffer in silence and shame for too long about the changes they undergo during menopause, with little access to information, support or even much of an open conversation."

Naomi feels "grateful" to everyone who shared their experiences with her while she wrote the book.

The actress said: "I can't wait for you to hear about the highs and lows and everything in between about this life stage and get some real, practical advice and comfort about how to take on these changes head-on."

Naomi also hopes that the book will help other women to navigate menopause.

She explained: "I want this book to read like you're sitting down over coffee and having an intimate chat with your girlfriend.

"I hope it will be of help for anyone trying to get a hold on this phase of life and make it a time of liberation rather than purely a time of trial."

Earlier this year, Naomi revealed that she suffered sleepless nights during the menopause.

The movie star's sleeping struggles ultimately led her to suffer anxiety and stress.

She told Forbes magazine: "For me, that [menopause] started with dry, sensitive, and irritable skin. But I would say the most unpleasant symptom I experienced was sleeplessness, because that is connected to so many other issues.

"When you don't sleep, you can't concentrate, you get brain fog, you get migraines, you get anxiety, you get stressed and depressed."
