University of California – Los Angeles via News-Medical – When new mothers complain that all those sleepless nights caring for their newborns are taking years off their life, they just might be right, UCLA research published this summer in the journal Sleep Health suggests. Scientists studied 33 mothers during their pregnancies and the first year of their babies’ lives, analyzing the women’s DNA from blood samples to determine their “biological age,” which can differ from chronological age. They found that a year after giving birth, the biological age of mothers who slept less than seven hours a night at the six-month mark was three to seven years older than those who logged seven hours or more. Mothers who slept less than seven hours also had shorter telomeres in their white blood cells. These small pieces of DNA at the ends of chromosomes act as protective caps, like the plastic tips on the ends of shoelaces. Shortened telomeres have been linked to a higher risk of cancers, cardiovascular and other diseases, and earlier death. “The early months of postpartum sleep deprivation could have a lasting effect on physical health. We know from a large body of research that sleeping less than seven hours a night is detrimental to health and increases the risk of age-related diseases.” Judith Carroll, study’s first author, UCLA’s George F. Solomon Professor of Psychobiology While participants’ nightly sleep ranged from five to nine hours, more than half were getting less than seven hours, both six months and one year after giving birth, the researchers report. “We found that with every hour of additional sleep, the mother’s biological age was younger,” said Carroll, a member of the Cousins Center for Psychoneuroimmunology at UCLA’s Jane and Terry Semel Institute for Neuroscience and Human Behavior. “I, and many other sleep scientists, consider sleep health to be just as vital to overall health as diet and exercise.” Carroll urged new mothers take advantage of opportunities to get a little extra sleep, like taking naps during the day when their baby is asleep, accepting offers of assistance from family and friends, and, when possible, asking their partner to help with the baby during the night or early morning. “Taking care of your sleep needs will help you and your baby in the long run,” she said. Co-author Christine Dunkel Schetter, a distinguished professor of psychology and psychiatry at UCLA, said the study results “and other findings on maternal postpartum mental health provide impetus for better supporting mothers of young infants so that they can get sufficient sleep -; possibly through parental leave so that both parents can bear some of the burden of care, and through programs for families and fathers.” Dunkel Schetter added that while accelerated biological aging linked to sleep loss may increase women’s health risks, it doesn’t automatically cause harm to their bodies. “We don’t want the message to be that mothers are permanently damaged by infant care and loss of sleep,” she emphasized. “We don’t know if these effects are long lasting.” ‘This Aisle Is Closed’: Using Epigenetics to Determine Biological Age The study used the latest scientific methods of analyzing changes in DNA to assess biological aging -; also known as epigenetic aging, Dunkel Schetter said. DNA provides the code for making proteins, which carry out many functions in the cells of our body, and epigenetics focuses on whether regions of this code are “open” or “closed.” “You can think of DNA as a grocery store,” Carroll said, “with lots of basic ingredients to build a meal. If there is a spill in one aisle, it may be closed, and you can’t get an item from that aisle, which might prevent you from making a recipe. When access to DNA code is ‘closed,’ then those genes that code for specific proteins cannot be expressed and are therefore turned off.” Because specific sites within DNA are turned on or off with aging, the process acts as a sort of clock, Carroll said, allowing scientists to estimate individuals’ biological age. The greater an individual’s biological, or epigenetic, age, the greater their risk of disease and earlier death. The study’s cohort -; which included women who ranged in age from 23 to 45 six months after giving birth -; is not a large representative sample of women, the authors said, and more studies are needed to better understand the long-term impact of sleep loss on new mothers, what other factors might contribute to sleep loss and whether the biological aging effects are permanent or reversible. Carroll and Dunkel Schetter reported last year that a mother’s stress prior to giving birth may accelerate her child’s biological aging, which is a form of “intergenerational transfer of health risk,” Dunkel Schetter said. Co-authors of the new study included researchers from the department of psychology, the department of psychiatry and biobehavioral sciences, and the department of human genetics and biostatistics at UCLA and from the psychology department at the University of Colorado at Colorado Springs.

3 Tips to Stay Healthy in the Sun

AHA Publisher — Fri, 21 May 2021 07:00:43 +0000

Dr. Don Colbert – For most of us, it’s warming up and it’s that time of year that we are becoming more active and spending more time outside. This is great because being outside has a myriad of benefits for our health. Sun exposure can help synthesize vitamin D, balance hormones, restore the circadian rhythm, and supercharge the mitochondria in our cells. Fresh air can help clear the lungs and oxygenate the blood. Contact with the earth’s magnetic field can relieve the body of electromagnetic stress by discharging built up static electricity. The smells of the forest can calm the nervous system and relieve stress. Out of all these benefits, the most controversial by far is sun exposure. While we are well aware of the astounding benefits of sun exposure and related vitamin D synthesis, we are also being told to avoid the sun’s damaging rays due to the risk of skin cancer. At the same time, we know that vitamin D is crucial in combating cancer cells. So what is the deal? How can we safely interact with sun? We have compiled a list of 3 tips to help you navigate this convoluted subject. Thankfully the truth is actually very simple, elegant, and easy to implement! 1. Moderate Sun Exposure We all know that excessive sun exposure and sunburn can damage the skin, accelerate aging, and lead to inflammation. But safe moderate sun exposure is actually essential to our health. While we know ultraviolet radiation can contribute to the formation of skin cancer in susceptible individuals, it is important to remember that the sun has a wide spectrum of light frequencies that change depending on time of year, time of day, latitude, and cloud cover. These spectrums can balance out the UV radiation at certain times in certain places. As with most things, it is all about balance. Many people have become overly-vigilant and apply high SPF sunscreen every time they go outside. This has led to a widespread epidemic of vitamin D deficiency. Vitamin D is critical for optimal functioning of the body and although supplementation is an option, the vitamin D you supplement will not be fully utilized without some amount of sun exposure without sunscreen. For most people 10-30 minutes outside in the sun during the morning or evening can be sufficient for vitamin D synthesis, especially if you are supplementing. If you plan on spending long stretches of time outside, especially between the hours of 10am and 4pm, then it may be prudent to mitigate your exposure. You can wear clothing and hats to cover your skin or seek shade when you feel you have reached your limit. As a last resort in situations where these measures are not practical, sunscreen is always an option. However, if you do choose to use sunscreen, beware of the toxic cancer-causing chemicals used by many brands. 2. Avoid Toxic Sunscreens Unfortunately, many sunscreens contain toxic ingredients and endocrine disrupting chemicals. Many of these chemicals have actually been found in some studies to promote skin cancer growth and free radical production in the body. This may be hard to believe, but in the years since sunscreen use began skin cancer rates have actually risen. A 2007 document from the FDA stated that: “The FDA is not aware of data demonstrating that sunscreen use alone helps prevent skin cancer,” and some reports show that sunscreens that contain vitamin A actually raise skin cancer risk! Oxybenzone is another common chemical in many sunscreens. This chemical is a known hormone disruptor and is not recommended for use on children. Other common hormone disrupting chemicals found in sunscreens that should be avoided are: avobenzone, octisalate, octocrylene, homosalate, and octinoxate. The skin easily absorbs anything it comes into contact with. In fact, our digestive system is lined with a type of skin! Our outer skin functions similarly to our inner skin through absorption and assimilation. This is why supplements such as magnesium and testosterone can be applied “transdermally,” or “through the skin.” When these harmful chemicals are slathered on the body the are easily absorbed into the bloodstream and eventually harm our health. Alarmingly, when the Environmental Working Group tested over 1,400 sunscreens, only 5% met their safety standards and over 40% were listed as potentially contributing to skin cancer! Fortunately, there are nutritional interventions that can help make the skin more resilient to sun exposure. 3. Eat Your Antioxidants! One of the most powerful nutrients to combat potential damage from the sun is antioxidant polyphenols. Antioxidants, as a group, are compounds that help to squelch free-radicals and thus prevent oxidative damage to cells in the body. Polyphenols are a subcategory of antioxidants. Sources of polyphenols include: Coffee, tea, berries, cocoa, olives, herbs, and spices. Polyphenols are phytonutrients meaning they are found in plants and derived from the plant’s interaction with sunlight. When plants are exposed to high levels of sunlight they produce polyphenols to protect themselves. When humans consume these polyphenols we derive similar protection. This is why God naturally provides foods like berries in the environment during the warmer months when days are long and sun exposure is intense. It is also why polyphenol rich foods are often found in tropical climates. By eating more polyphenols you provide your body with the antioxidants necessary to combat the oxidative damage caused by the sun. A potent and convenient source of antioxidant polyphenols can be found in Dr. Colbert’s Organic Red Supremefood formula. Don’t Be Afraid! Excessive sun exposure and associated damage to the body is certainly something to be concerned about. But a healthy body can easily handle moderate amounts of healthy sun exposure and it is in fact necessary for good health! So be vigilant to avoid sun burn but do not be afraid of the sun! It provides life giving energy and nutrients and nothing on this planet would exist without it. As long as you maintain a healthy lifestyle, drink plenty of clean filtered or spring water, and follow the tips in this article, you will be able to safely enjoy the sun without risk of adverse side effects.
