Posted by Sarah McClutchy on

Dr. Darlyne Johnson, MD is a New England-based OB/GYN and co-author of the clinical study The Efficacy of the BedJet Climate System® for Peri-Menopausal Night Sweat and Hot Flash Symptoms and Corresponding Impact on Sleep. The study was published as an abstract in the December 2018 issue of the scientific journal Menopause: The Journal of The North American Menopause Society. The study results were presented at the North American Menopause Society Conference in San Diego, CA on October 4th, 2018.

We sat down with Dr. Johnson to ask her a few frequently asked questions about perimenopause, menopause, and sleep issues. Here’s what she said.

Q. What is perimenopause?

Dr. Johnson: Perimenopause, also known as the "climacteric", is the phase that precedes menopause. It typically lasts three to five years. Symptoms of perimenopause include:

  • Decreased libido or sexual health
  • Mood swings
  • Depression
  • Insomnia
  • Hot flashes
  • Night sweats

Q. What is Menopause?

Dr. Johnson: Menopause is a normal biological event that occurs in all women. Menopause typically occurs between 40 and 60 years old, and the average age in the United States is 51 years old. It is diagnosed by loss of menstrual periods for 12 consecutive months. Symptoms of menopause include:

  • Hot flashes
  • Mood swings
  • Libido or sexual health issues

Q. How is sleep affected during perimenopause and menopause?

Dr. Johnson: Hot flashes and night sweats during perimenopause and menopause can be extremely disruptive to sleep. Up to 80% of women suffer from sleep disruption due to these symptoms. Different factors may worsen hot flashes and night sweats in different people. Common triggers include:

  • Alcohol
  • Spicy food
  • Caffeine
  • Smoking

Q. How can women find relief from bedtime symptoms of perimenopause/menopause?

Dr. Johnson: Hormonal treatment is often prescribed to treat perimenopausal sleep issues with varying results. For women who don’t want to or can’t use hormonal treatment, the BedJet is an excellent solution.

In a recent clinical study, 46 perimenopausal/menopausal women that were experiencing hot flashes, night sweats, and sleep disturbances were tested for three weeks while using a BedJet. The study’s primary results included:

  • 94% of study participants reported improved sleep
  • 89% of study participants reported improved daytime function
  • 85% of study participants reported reduced hot flashes and night sweats

Based on the study results, the BedJet System is the first clinically proven device to be highly effective for treating poor quality of sleep in menopausal women.

How did I live without this?

I have watched my wife suffer with menopause hot flashes for years. Finally I started looking at what I could buy to help her at night. This system is so awesome I am going to order one for my side of the bed. Works great on cool and now that we are in winter the warming is also incredible!
