BONES AND SUNLIGHT- very important
The same elements that protect plant leaves from sunlight protect you from UV. (another reason to eat raw green foods) Without sunlight, the bones cannot become calcified. Sunlight builds the immune system and increases oxygenation of the skin. It lowers blood sugar. Sunlight brings more blood to the skin surface which helps heal cuts, bruises and rashes. Open wounds and broken bones heal faster in sunlight. Sunlight improves eyesight and hormones. The best UV protection is inner protection- from the food you eat. Get at least 30 minutes of sunlight each day. There is no mistake in nature. We need sunlight.
-makes bones denser and muscles stronger
It was shown that rats fed exclusively a diet of flour, calcium lactate, sodium chloride, and ferric citrate developed bone lesions characteristic of rickets in human infants. However, if the rats were exposed to sunlight for 15 or 30 min each day, there were no symptoms of rickets like those in the control rats housed entirely in the dark. This study illustrated the necessity to treat light as an experimental variable.
Vitamin D is not really a vitamin at all, because there is no dietary requirement as long exposure to sunlight is sufficient to initiate the conversion of 7-dehydrocholesterol to vitamin D3. The active form of the hormone is necessary for calcium absorption by intestinal cells and calcium uptake by bone-forming osteoclasts.
Because of the seriousness of rickets and because of seasonally inadequate sunlight in many geographical regions, most individuals obtain vitamin D from food such as eggs and fish oils, but there really is no replacement for pure sunlight. Extended withdrawal results in many health issues, particularly bone-related.
Rickets seems to be making a small comeback due to fear of skin cancer. The disease manifests itself as abnormal bone growth, and enlargement of cartilage at the ends of long bones. Where bones must support weight, such as the legs and pelvis, the skeleton is likely to become bent or deformed. The result is often knock-knees, bowlegs, and deformities of the chest and pelvis. In temperate climates or the tropics, vitamin-D deficiency usually results from poor diet rather than from lack of exposure to ultraviolet rays of sunlight.
Symptoms of sunlight deficiency include: ¥ Painful bones.¥ Bone pain or tenderness - arms, legs, spine, pelvis ¥ Dental deformities¥ Restlessness, especially at night ¥ Weakness, progressive - decreased muscle tone (loss of muscle strength), decreased muscle development ¥ Muscle cramps¥ Increased susceptibility to fractures ¥ Fever. ¥ Dental problems, such as deformed teeth or soft tooth enamel. ¥ Deformities of the skeleton, such as bowed legs, kyphosis ('hunch-back'), scoliosis (sideways curves of the spine), outward jutting breastbone or abnormal skull shape. ¥ 'Rickety rosary' (osteoid bumps), which are abnormal bumps of bone¥ Slowed growth and development. ¥ Progressive loss of muscle tone and strength. ¥ Muscle cramps. ¥ Tetany (relentless muscle spasms)
A range of causes Some of the contributing factors and causes of rickets include:
¥ Lack of dietary calcium. ¥ Lack of dietary vitamin D. ¥ Insufficient sunlight exposure. ¥ The use of sunscreen lotions when outside. ¥ Exclusive breastfeeding without vitamin D supplements for the baby. ¥ Disorders of nutrient absorption such as short bowel syndrome. ¥ Kidney disorders such as renal tubular acidosis. ¥ Some liver disorders that affect absorption of dietary fats. ¥ Hyperparathyroidism.
Maintaining good posture helps to correct skeletal deformities
Vitamin D deficiency not only causes rickets among children but also precipitates and exacerbates osteoporosis among adults and causes the painful bone disease osteomalacia. Vitamin D deficiency has been associated with increased risks of deadly cancers, cardiovascular disease, multiple sclerosis, rheumatoid arthritis, and type 1 diabetes mellitus.
The avoidance of all direct sun exposure increases the risk of vitamin D deficiency, which can have serious consequences.
Bone development is influenced by a number of factors, including nutrition, exposure to sunlight, hormonal secretions, and physical exercise.
Regular exposure to sunshine, in addition to helping fight depression, also improves bone density. This is because vitamin D is made by the action of sunlight on the skin. How much sunlight does one really need for D synthesis? Well, it depends upon the time of day, season of the year, where you live, your age, and how much pigmentation occurs in your skin. People who live at high latitudes can't make vitamin D during winter months because of the low angle of the sun, so that blood levels of vitamin D are usually lower in wintertime. Women in Maine lost about 3% of their bone mass during winter due to decreased vitamin D blood levels. Part of the loss was recovered the following summer. People living in Boston and Chicago and further north can't make vitamin D from November to February while people in Columbus, Ohio and Denver cannot make vitamin D during January and February. People in Southern California, Texas or Florida receive sunlight all year around that is intense enough for adequate vitamin D synthesis.
When someone remains motionless in an overstretched or physiologically unsuitable position for extended periods musculoskeletal problems may occur.
What causes back problems? If ligaments and muscles are weak then discs in the lower back can become weakened. Poor physical condition, poor posture, lack of exercise, and excessive body weight contribute to the number and severity of sprains and strains.
Back injuries can be reduced by better physical conditioning, resulting in stronger muscles to hold the spine in proper posture and less body weight for the back to support. Doing work around the house or yard you should try to maintain proper posture. Prolonged sitting or standing, particularly in forward, bent or slouched positions, can cause muscle fatigue, which can lead to leg and back problems.
****MOST PHYSICAL PROBLEMS ARE RELATED. JUST BECAUSE THE MEDICAL SOCIETY LIKES TO LABEL SETS OF SYMPTOMS WITH SPECIFIC NAMES, DOES NOT MEAN THAT ONE CONDITION IS REALY THAT DIFFERENT FROM ANOTHER.
Here are some similar conditions. After a while, you will notice similarities within all the conditions.
The parathyroid glands
A diet low in calcium or vitamin D can result in weakened bones. The four tiny parathyroid glands are located around the thyroid in the throat. The main function of these glands is to make the parathyroid hormone (PTH), which regulates the amounts of calcium, phosphorus and magnesium in the bones and blood.
Calcium is crucial for healthy bones, but blood-borne calcium is also needed for proper functioning of nerve and muscle cells. When calcium levels in the blood are too low, the parathyroid glands release extra PTH, which leeches calcium from the bones. Low vitamin D levels cause calcium levels to drop, because calcium can't be absorbed by the body without adequate vitamin D. Over time, the constant 'borrowing' of calcium from the bones weakens their structure until they become soft, easily broken and deformed.
Hyperparathyroidism is a condition characterised by overactive parathyroid glands. The excessive levels of PTH strip calcium from the bones. Some of the causes include kidney disease and certain medications. Hyperparathyroidism is more common in women aged 50 years and over. Interestingly, hypoparathyroidism (an underactive gland) can also cause osteomalacia, as parathyroid hormone is a major regulator of the renal production of vitamin D.
Paget's disease of bone
Paget's disease of bone is a chronic disorder that often results in enlarged and deformed bones. The excessive breakdown and formation of bone tissue that occurs with Paget's disease can cause bone to weaken. This, in turn, can lead to bone pain, arthritis, deformities, and fractures. (Read about "Arthritis and Rheumatic Diseases" "Bone Fractures")
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), Paget's disease of bone may be caused by a viral infection. There is also a hereditary factor since the disease may appear in more than one family member. It is most common in people over the age of 40. Sometimes, there are no noticeable symptoms. When symptoms do occur, NIAMS says they can include: ¥ Bone pain, which is the most common symptom and can occur in any bone affected by the disease. ¥ Headaches and hearing loss (Read about "The Ear and Hearing"), which may occur when Paget's disease affects the skull. ¥ Pressure on nerves, which may occur when Paget's disease affects the skull or spine. (Read about "The Spine") ¥ Increased head size, bowing of limb, or curvature of spine (Read about "Curvature of the Spine") ¥ Damage to cartilage, which may lead to arthritis
Osteopetrosis is a congenital condition in which the bones are overly dense. This happens because the body makes more new bone than it breaks down. Although the bones are dense, however, they are not very strong and tend to break more easily. In addition, problems with the bone marrow mean that the person's immune system may be weakened. (Read about "The Immune System")
NIAMS says there are three major types of osteopetrosis. ¥ Malignant infantile form, which is very severe. It is inherited when both parents have an abnormal gene that is passed to the child. ¥ Intermediate form, which is less severe than the malignant infantile form. It is found in children younger than 10 years old, and usually does not shorten life expectancy. ¥ Adult form, which is a milder type of osteopetrosis that is found in adults between 20 and 40 years old. This form rarely causes a significant reduction in life expectancy.
Symptoms can include increased bone fractures (Read about "Bone Fractures"), frequent infections, blindness and/or deafness. Treatment options include physical therapy. In severe cases, bone marrow transplant can be an option.
Bone tumors may be benign (noncancerous) or malignant (cancerous). According to the National Cancer Institute (NCI), benign bone tumors are more common than malignant ones. Benign tumors do not spread and are usually not life-threatening. However, they can grow and compress healthy bone tissue; they can also absorb or replace healthy tissue with abnormal tissue.
The American Academy of Orthopaedic Surgeons (AAOS) says common benign tumors include: ¥ Osteochondroma, which is the most common benign bone tumor. It is marked by bony growths that project from the surface of the affected bone and is most common among teens and young adults. ¥ Giant cell tumor, which usually starts in the ends of bones and tends to occur more frequently in young adults. It can cause extreme pain. ¥ Unicameral bone cyst or solitary bone cyst, which is a fluid-filled cavity that can weaken bones, leading to increased risk of fracture. (Read about "Bone Fractures") It is more common in children. ¥ Osteoid osteomas, which are small tumors that can develop on any bone, but are most often seen on the arms and legs ¥ Benign cartilage tumors
In many cases, according to AAOS, benign bone tumors need no treatment other than observation. In the case of cysts, fluid may need to be removed by needle.
It may be necessary to remove some types of benign tumor to reduce the risk of fracture and disability. It's also possible that a benign tumor may come back after removal. Some types of benign tumors can also become malignant (i.e. turn into cancer) and metastasize.
Osteonecrosis occurs when a portion of bone loses its blood supply and begins to die. AAOS says doctors see about 10,000-20,000 new cases of osteonecrosis each year. Common locations include the knee and the hip, but other areas can be affected as well. The exact cause is unknown, but AAOS says factors that increase your risk of developing osteonecrosis include:
¥ corticosteroid use
Osteonecrosis causes pain, swelling, and limited range of motion. Strengthening exercises may be the best option.
