Vitamin D, also known as the sunshine vitamin, is primarily known for its role in assisting with calcium absorption and building strong bones. But Vitamin D also plays a vital role in a variety of other bodily processes such as immune health, sleep and mood, muscle maintenance, and prevention of osteoporosis, cancer, cardiovascular disease, diabetes, and a number of other chronic diseases. Knowingthis, most of us should be flocking to stock up on this powerful vitamin. But with all of the conflicting information on recommendations and intake sources, it is difficult to know exactly how much Vitamin D you should be getting and from where.
Conflicting Views on Vitamin D
There is a lot of confusing information out there on the proper dosage of Vitamin D. When Vitamin D first arrived on the scene in the early 20th century, doctors began to liberally recommend Vitamin D through the consumption of cod-liver and spending time in the sun. Food manufacturers began to enhance a variety of foods with Vitamin D. But in the 1950’s health officials began to become cautious of lifestyles and diets overloaded with Vitamin D after an outbreak of hypercalcemia, a condition in which the body has too much-circulating calcium, and stopped promoting it as much.
Vitamin D made a re-entrance in the health scene in the early 2000’s as research demonstrated its need for optimal bodily functions. In 2010, the Food and Nutrition Board of the Institute of Medicine, now known as the National Academy of Medicine, recommended adequate amounts of Vitamin D blood serum levels be at 20 ng/mL, far below the 30 ng/mL recommended by researchers.
So what exactly is Vitamin D, why is it important, and how much should we actually get?
Vital Roles of Vitamin D
Vitamin D is a nutrient we intake from both food and the sun when our skin is exposed to UVB rays. Once Vitamin D is in your body, it makes the hormone calcitriol, a hormone necessary for calcium and phosphorus absorption. Every cell in our bodies, including immune cells, contain Vitamin D receptors. This explains Vitamin D has a vital role in immune function and prevention of diseases such as cancer and autoimmune diseases.
Assessing Your Need of Vitamin D
Before assessing how much Vitamin D you feel you need to get, it is important to know that everyone is different in their Vitamin D needs. Factors such as how much time you spend outside vs. inside, where you live, how often you apply sunscreen, and how much Vitamin D are you actually getting from your diet, all influence your Vitamin D needs.
The best way to know how much Vitamin D you, as an individual, need is to get tested. It is recommended you get tested each year, or ideally, every 6 months. Most doctors include lab work to measure the active form of Vitamin D, 25-hydroxyvitamin D, or 25(OH) D, during an annual exam. You can also purchase a direct-to-consumer lab for about $60.
An accurate way of assessing your personal Vitamin D levels is to check your parathyroid hormone (PTH) levels. If you are deficient in Vitamin D, your parathyroid gland releases more PTH. So if your PTH levels are high, it may be an indication of low Vitamin D levels.
The important thing to remember is that everyone is different in their Vitamin D levels and needs. Vitamin D levels can fluctuate based on nutrition, sun exposure, and geographical location.
Too Much or Too Little Vitamin D
Since Vitamin D affects multiple bodily functions, it is important to remain within a range that is ideal for your body. If Vitamin D levels are too low, it can affect hormones such as cortisol and thyroid. If it is too high, it can throw off other hormones in the body. About 70% of the world’s population is deficient in Vitamin D. Low levels of Vitamin D can cause migraines, muscle and joint pain, depression, and inflammation.
Too much vitamin D, however, can also cause adverse side effects. Excessive levels of Vitamin D can lead to hypercalcemia. Other symptoms associated with excess Vitamin D include poor appetite, nausea, vomiting, frequent urination, and kidney problems.
Practical Ways to Boost Vitamin D Levels
One of the easiest ways to get Vitamin D into your life is to get outside and expose your skin to natural sunlight. The amount of unprotected sun exposure you need depends on your skin tone. If your skin tone is fairly light, 10-15 minutes outside is enough time for your skin to absorb the sun’s benefits. For those of you with darker skin tones, it may take up to two hours.
Another way to get Vitamin D is through your diet. Vitamin D is a fat-soluble vitamin, meaning you need dietary fat in order for Vitamin D to be properly absorbed in the body. Whole food sources of Vitamin D include cod-liver, fatty fish such as salmon, sardines, and mackerel, and eggs.
Lastly, supplementation is another way to get Vitamin D when sun exposure or diet sources are limited. It is best to choose Vitamin D3 when choosing to use supplements. Vitamin D3 is the most bioavailable for of Vitamin D and is 85% more effective at raising Vitamin D blood serum levels than Vitamin D2. Supplements can be found in both pill form and liquid forms.
Vitamin D from the sun stays in our bodies 24-48 hours and 12-24 hours from food sources. It is important to get adequate amounts daily via a combination of sources. Below are recommendations for Vitamin D supplementation from the Institute for Functional Medicine.
|25(OH) D Level||Supplement Dose|
|<10 ng/mL||10,000 IU/day|
|10-20 ng/mL||10,000 IU/day|
|20-30 ng/mL||8,000 IU/day|
|30-40 ng/mL||5,000 IU/day|
|40-50 ng/mL||2,000 IU/day|

Taking a breath is one of the first actions we perform when we come into this world but rarely do we ever give it any thought. Crucial to our survival, our body has adapted itself to perform the act of breathing subconsciously. While this makes it easier for us, since we don’t have to think before taking a breath, it may not always be best for our bodies.
The diaphragm is a dome shaped organ designed to support deep breathing, and is located at the bottom of the rib cage. Most people have developed an incorrect breathing technique and tend to breathe using the intercostal muscles as opposed to via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation. Most people who breathe shallowly do it throughout the day and are almost always unaware of the condition.
Before we get to learning about the diaphragmatic breathing exercises or actually doing them, here’s a small test to check your own breathing technique. Let’s find out whether you breathe from your belly, or your chest.
Test your breathing technique
Place one hand on your abdomen (stomach region) near the belly button, and the other on your upper chest, relaxing your body completely. Make an effort to regularize your breathing; the aim is to observe your breathing pattern in its unconscious form. Take a couple of slow breaths, they don’t have to be unnaturally deep, and pay attention to the way your body moves. Is your stomach/chest expanding? Where do you feel you’re drawing air from?
If you’re a chest breather, your upper hand is likely to have moved up and down with every breath. This isn’t an uncommon among most people who’ve developed an incorrect breathing technique over the years. There are a number of exercises you could try to rectify your breathing technique, most involving learning to use one’s diaphragm.
Posture is a crucial factor in determining one’s breathing technique and isn’t to be taken lightly. Make sure you’re standing straight, with your feet placed firmly on the ground and equal weight on either side. Consciously relax your shoulders (they usually hold a lot of tension) and any other part of your body which feels tensed. Now place both your hands, one on top of the other, on your abdomen (belly button) and take a deep breath.
When you breathe in, feel your stomach and rib cage expand rather than your chest. Breathe out, and gently push your stomach back in, tightening your muscles as you take a second breath. Keep the hand on your chest as still as possible. If you are experiencing any difficulty, try visualizing your breath as fire, or light, something to help you pull your breath from your lungs rather than chest.
You may get tired while doing this exercise initially, but keep at it and soon it’ll become your natural breathing technique. Practice for 10-15 minutes every day and increase the frequency as you grow more comfortable.
Lie down flat on your back, in the shavasana pose, and relax your body. Now place a book on your abdomen and focus on breathing such that your stomach rises a few inches, and subsequently falls when you breathe out. Continue this exercise for 3-5 minutes before reverting to Exercise 1, which will aid in reconnecting your conscious brain with the diaphragm. Once you’re comfortable, try with more than one book, but make sure they aren’t too heavy.
One of the ways to forcefully stop yourself from chest breathing is by using a belt. Fasten and buckle the belt around your lower ribs so that you cannot inhale using the rib cage or chest. Now breathe in deeply, and you will find yourself forced to breathe through the abdomen. Keeping the belt on and concentrating on your breathing is a fast way of ensuring diaphragmatic breathing. However, it may not always be enough; it is important to develop the tools to continue breathing right once the belt is off as well.
Note: Make sure you don’t let yourself hyperventilate; breathe slowly and keep relaxed.
Body breathing, a fairly advanced exercise is aimed at allowing your body to breathe for you automatically. First, breathe out all the air in your lungs, as much as you can. Then, with your mouth open, allow the breath to be recalled automatically back in. You will find that your breath equalises itself; the same amount of air that is exhaled will be inhaled again. This is one of the most profound parts of breath training – allowing the body to breathe itself.
Don’t wait anymore, breathe right from today!

Ask yourself – when was the last time you went to the bathroom? If you’re suffering from constipation, you probably paused to think a while before answering.
A 2011 survey by United BioSource Corporation estimated that about 30.8 % of American men and women experience chronic constipation. Be it an unhealthy diet or lack of exercise, constipation can be caused by a number of factors. Most of these however, are are easy to tackle by oneself.
Sometimes though, constipation can be severe and a doctor’s opinion is well advisable. In those cases, treatments such as regular enemas and other laxatives may be prescribed. But before you head to the doctor, or self-prescribe any medicines, try these simple tips to get your bowels moving.
Water Is Your Best Friend
Drink six to eight glasses of water daily to soften your stool.
Hard stool can be extremely harmful for your rectum walls, often tearing or damaging it beyond repair. The best and easiest solution for constipation is to drink six to eight glasses of water on a daily basis. Keep an empty 64-ounce bottle by your side, and remind yourself to keep drinking. After a while, you won’t look at it as a compulsion anymore.
If your bathroom time is set in the morning, two glasses of warm water as soon as you wake up can get the bowels moving too.
Tickle your sweet tooth
Prunes or prune juice is the oldest remedy in the book.
While you may have heard of the classic cure, it’s important to understand why these tiny, sweet fruits are so useful. Prunes act as a natural laxative, owing to its high content of fiber and sorbitol. Both these nutrients add bulk to your stool, making it easier to go.
Apples and plums are good alternatives too owing to their high fiber content, especially in their skins. So the next time you think if peeling the skins, remember its perks!
Have people advised you that coffee is not good for your health? Maybe, maybe not.
While most people need a cuppa in the morning simply to wake them up, caffeine has proved to be a natural stimulant for the digestive system. However, like everything else, coffee too is good only in small proportions. A cup or two a day could wake your bowels, but more than that, could have the opposite effect.
A diuretic, coffee tends to make you urinate frequently, which could dehydrate your body and cause constipation. So watch your mug and don’t go overboard!
Exercise is found to be directly proportional to your bowel movements.
Have you ever felt like using the washroom after a nice, long walk or run? Or were you stuck at the office, sitting at a desk the entire day?
Any kind of physical activity be it running, walking or swimming, stimulates the body’s bowel function. It decreases the time taken for food to move through your intestines, allowing the stools to remain moist. Though there’s isn’t a given scientific explanation, a healthy routine of thirty minutes of exercise (at least) three times a week is said to be enough to prevent constipation. Don’t be too ambitious however and exercise immediately after dinner, that could cause cramps!
Squat. Don’t strain.
Last but definitely not the least, squatting is the way to go!
With constipation comes the desperate attempt to force stool out of your body. While this might (more likely not) do the job, forcing causes more harm than good. It increases the risk of rupturing rectal tissue, also known as prolapse of the rectum. There is however, a healthier and easier way out.
If you can’t go even after 15 minutes of trying, prop your feet on a kitchen stool/toilet seat and bend your knees without sitting down completely. This creates a natural pressure on your lower abdomen, which helps the stool to move along easily.
If this doesn’t work either, make sure you see a doctor without delay!Lear More
