A new study shows that women who have the habit of sleeping with the lights on are at an increased risk of weight gain.
Who would have suggested that sleeping with artificial light from a lamp or TV would put women at risk of weight gain and even obesity? Holy cow! But it's true.
Researchers reported in the Journal of the American Medical Association that women sleeping with artificial light are at greater risk of weight gain, obesity, a higher body mass index and a larger waist circumference than those who do not. Turning on the light or the TV in the bedroom while sleeping is associated with these frustrating and common problems that almost every woman knows too well.
You may wonder if it is really about fire or something else, such as age, race, physical activity, diet, amount of sleep, etc. Researchers controlled these factors and found that, in fact, the problem is not only the presence or absence of artificial lighting
Compared to the weight of women sleeping without artificial light, women sleeping with the lights on were:
- 11 pounds heavier
- 22% are more likely to be overweight,
- 33% increased risk of obesity.
It is unclear why sleep with artificial lighting is associated with a risk of weight gain. Most women are already struggling with this issue! Researchers suggest that light can disturb your normal phases of sleep enough to alter the hormones that regulate your appetite – but we don’t need it! It can also reduce the quality of sleep, so that we feel sleepy during the day, and it can make us reach for sugar and carbohydrates to keep going.
We can add this new information to what we already know about the benefits of a good night's sleep for your appearance. A 2010 study by the Faculty of Psychology at Stockholm University showed the sad effects of poor night sleep on your appearance.
What happens to your face if you do not get enough sleep?
Sleep quickly affects your appearance. The day after a bad dream, expect to see more
- hanging eyelids
- red eyes (larger than normal redness)
- swollen eyes (more than any typical edema)
- dark circles under the eyes,
- pale skin,
- increased wrinkles / fine lines,
- additional saggy corners of the mouth.
In this study, a good night's sleep was defined as 8 hours. Sleep deprivation was 5 hours.
I wrote about this study in the past, including my advice on how to counter the visible effects of sleep deprivation on your face. As the researchers said,
Since these areas of the face are important in communication between people, signs of sleep deprivation and fatigue can carry social consequences for a person deprived of sleep in everyday life.
Someday it just won’t work, and you need to know how to revive your “communication” with your face after not getting enough sleep. If you know that you are getting sleep deprivation, click here to see my quick remedies to counter some of the facial effects.
What struck me was that now we know that sleep affects not only our transient manifestation and physiology. Longer-term effects, such as weight gain, also affect.
Combining the information from these two studies is a wake-up call (pun intended) that we need 8 hours of sleep in a dark room to look and feel better.
I know that light adversely affects the quality of my sleep, and I sleep with an eye mask to help block the light. I bought a really good one on vacation and use it every night. I found it in Australia at Love Stories, a store selling the coolest pajamas and intimate friends. I bought my favorite pair of pajamas there.
At 60, I had a vicious dream – between menopause, career stress and just aging – and I appreciate a good night's sleep. For me, this is a priority, so my nightly routine is deliberate. This procedure is actually called "sleep hygiene." I will share this with you:
60-year-old dermatologist Dr. Cynthia Bailey night hygiene and night skin care:
I usually wake up around 7 in the morning. This is a good 8 hours, adding time for an overnight stay in the toilet (60-year-old adventure). I feel renewed and ready for the day.
Fortunately, I sleep well after many years of insomnia. My face looks less tired and saggy. Now that we know about weight loss and sleep problems, I’m doubly grateful.
Dermatologist night skin care at age 60:
Daily Face Cream is my favorite moisturizer for face that surpasses all my anti-aging nightly routines.
How is your dream Do you have any tips to get a good night's sleep? What is your nightly multitasking skincare routine? I would love to hear your stories. I know that many of us share sleep problems.
