Sleep: Essential for Mind-Body Health
Adults and children alike are spending more time awake late at night to study, work, or have fun. All those late nights may be slowly killing us. More than 20 years of research shows us that sleep is vitally important to physical and mental health.
Most of what we know about sleep and health comes from studies of what happens to the mind and body when we don't sleep enough, or at all. In animal and human studies, living without sleep for even a few months resulted in death. Sleeping fewer than 8 hours a night on a regular basis is associated with increased risk for diabetes, heart disease and stroke, depression, colds and flu, and obesity.
While We Are Sleeping...
Sleep affects brain chemistry and has an important role in the functioning of the nervous, immune and endocrine systems. During sleep we develop and reinforce neural pathways involved in memory, learning, and emotion. New research suggests sleep helps flush toxins from the brain.
While we are sleeping, the body manufactures hormones that repair damage caused by stress and the environment in which we work and play. Growth hormone cleanses the liver, builds muscle, breaks down fat, and helps normalize blood sugar. We also produce hormones that help fight infections. If we aren't getting sufficient sleep, we get sick more often and take longer to recover. Lack of sleep increases inflammation, which is has been linked to heart disease and stroke.
Skimping on shut-eye is linked with obesity in adults and children. Lack of sleep interferes with the levels of metabolic hormones that signal when you're hungry and when you're full.
The amount of sleep you need varies based on age, activity level, quality of sleep, and genetics (e.g., some of us really are night owls). Infants typically require 14-15 hours of sleep per 24-hour period; young children about 12 hours; teens about 9 hours, and most adults 7-9 hours. A general rule of thumb for determining your sleep requirement: If you do not wake feeling refreshed, you may not be getting enough sleep.
Are You Sleep Deprived?
You don't have to pull "all-nighters" to become sleep deprived. A sleep debt of just 1-2 hours a few nights a week can affect your health and performance. To become fully well-rested and regain energy after a sleep debt, get an extra hour of sleep each night for one week.
If you experience any of the following the signs of sleep deprivation, talk to your healthcare provider about natural approaches to getting your sleep back on track.
· Daytime drowsiness; fatigue
· Poor memory; difficulty concentrating
· Changes in appetite
· Difficulty dealing with stress
· Muscle tension; impaired vision
· Increase in accidents or clumsiness

The Power of Sweet Potato
Sweet Potato is a powerhouse of nutrition. This vibrant orange tuber is rich in vitamins, antioxidants, anti-inflammatory nutrients, and blood sugar-regulating nutrients. The antioxidant Beta-carotene, which gives Sweet Potato its orange flesh, is necessary for your body to produce Vitamin A. We need vitamin A for eye health, for a strong immune system, and for healthy skin. One medium Sweet Potato provides 100% of your daily needs for Vitamin A, as well as a healthy dose of vitamin C, several of the B vitamins, potassium, calcium, iron, magnesium, zinc, and vitamin E.
Some research has shown that, as antioxidants from Sweet Potato and other phytonutrients pass through the digestive tract, they act in ways that may lower the health risk posed by heavy metals. Scientists are also studying the anti-inflammatory nutrients contained in purple Sweet Potatoes, which may provide protection against certain types of cancer. Sweet Potatoes also have a fascinating ability to potentially improve blood sugar regulation. Researchers are interested in determining what effect this may have on Type-2 Diabetes. High in fiber, including Sweet Potato in your diet can promote regularity of the bowels and healthy digestive function.
You can enjoy Sweet Potato as a main course, side dish, in soups, or in desserts. When shopping for these versatile veggies, remember that Yams are not the same as Sweet Potatoes. The two are not in the same "food family" and each has a different nutrient profile. Yams are usually imported from Africa or Asia, whereas the Sweet Potato is grown abundantly in the U.S. Finally, Sweet Potato color, both flesh and skin, can range from white to yellow-orange to brown or purple. There also are "firm" or "soft" varieties, which can make a difference in your cooking.
Calcium Essential for Strong Bones, Sound Sleep
Did you know that Calcium, the most abundant mineral in the human body, is not only essential for strong bones, it also supports healthy functioning of the cardiovascular, musculoskeletal, and nervous systems? When it comes to sound sleep, insufficient dietary Calcium has been associated with insomnia. Calcium is instrumental in the way our brains cycle through the stages of sleep and in the ability to generate brain chemicals, including tryptophan, associated with deep sleep.
The best way to get calcium is through whole foods. Dairy products are abundant in the mineral in a form that's easy for most people to digest. Vegans sources of this mineral include almonds, dark leafy greens, and tofu. However, figuring out how much calcium you're actually getting from veggies is tricky. If a vegetable contains oxalic or phytic acid, then the calcium may be poorly absorbed because of the acids. For example, 1 c. of frozen spinach contains nearly as much calcium as 1 c. of milk, but only a tenth as much is absorbed because of the oxalic acid.
For a healthy adult, the recommended intake for a Calcium supplement is 1,000 - 2,000 mg daily, depending on health status and lifestyle habits including exercise. There are many factors and forms of calcium supplements (e.g., carbonate, citrate), that affect how well the body absorbs the mineral. Also, calcium supplements can interact with other medications. Too much calcium can stress other bodily systems, leading to health problems. For these reasons, consult with a health practitioner as to which type and dosage of calcium is best for you.
Soothing Herbs for Restful Sleep
Three herbs well known for calming effects are Lavender, Chamomile and Oats. Perhaps, not quite as well known as the first two herbs, Avena sativa (Oats Milky Seed or Oat straw) is the grain* source of oatmeal. The entire plant is abundant in minerals and trace nutrients, in particular the B-vitamins, calcium, and magnesium, which help soothe and strengthen the nervous system. As an herbal remedy, oats can ease the effects of stress, anxiety or exhaustion and resolve sleeplessness. Oats contain the amino acid tryptophan, which research shows promotes sleep. In fact, Scottish folks suggest a bowl of oatmeal before bedtime to ensure restful sleep!
Of its many medicinal uses, lavender is known worldwide as an herbal "rescue-remedy" for reducing stress, anxiety and tension. Its strong, relaxation-inducing scent is used in massage therapy lotions, candles, bath salts, tinctures and essential oils. As one of the few essential oils that can be applied directly to the skin, a dab of lavender on the inside of your wrist can help soothe a stressful moment. Lavender is also used in teas, often paired with chamomile. If you aren't a tea-drinker, dried lavender can be added to a sachet and placed beneath your pillow to help induce sleep.
Chamomile has been used for centuries as an herbal remedy for easing stress and insomnia. Today, these uses continue and we also have good clinical evidence for the safe use of chamomile preparations to help reduce inflammation, promote more restful sleep, ease colic and digestive upset, and facilitate wound healing when used in a cream. While chamomile seems to reduce the effects of anxiety, which can contribute to sleeplessness, more research is necessary to demonstrate the specific properties of chamomile that contribute to its effects.
Since there are many different ways to prepare these herbs, and some people can be allergic to certain herbs, do check with your wellness practitioner for the best approach to help you relax and get a good night's sleep.
*If you have sensitivity to gluten, be sure to use an oat product produced using gluten-free manufacturing practices.
