Fact:Eye exercises will not improve or preserve vision or reduce the need for glasses. Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises.
As the eyes age, problems with vision become more common. Learn how to recognize the risk factors and symptoms of specific eye diseases— cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy — and what steps one can take to prevent or treat them before your vision deteriorates.
Myth: Reading in dim light will worsen our vision.
Fact: Dim lighting will not damage our eyesight. However, it will tire our eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over the shoulder. A desk lamp with an opaque shade pointing directly at the reading material is ideal.
Myth: Carrots are the best food for the eyes.
Fact: Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against cataracts and age-related macular degeneration. Just don’t expect them to prevent or correct basic vision problems such as nearsightedness or farsightedness.
Myth: It’s best not to wear glasses or contact lenses all the time. Taking a break from them allows our eyes to rest.
Fact: If we need glasses or contacts for distance vision or reading, we should use them. Not wearing glasses will strain our eyes and tire them out instead of resting them. However, it will not worsen our vision or lead to eye disease.
Myth: Staring at a computer screen all day is bad for the eyes.
Fact: Using a computer does not damage our eyes. However, staring at a computer screen all day can contribute to eyestrain or tired eyes. People who stare at a computer screen for long periods tend not to blink as often as usual, which can cause the eyes to feel dry and uncomfortable. To help prevent eyestrain, we should adjust the lighting so it doesn’t create a glare or harsh reflection on the screen, it is advised to rest the eyes briefly every 20 minutes, and make a conscious effort to blink regularly so that our eyes stay well lubricated.
It can be a frightening moment. When the doctor diagnoses an eye disease such as glaucoma, cataract, or AMD, we immediately worry about losing our sight or becoming seriously vision-impaired.
It’s important to know what to do not only when disease strikes, but what to do before and after. We should know the warning signs and how a diagnosis is made. And the best treatment options for that.
The good news is, with the proper treatment decisions, those eye diseases can be addressed and controlled and their potential to compromise our sight can be halted.
Our eyes do change as we get older. That’s a truth we can do little about. It’s the consequences we can change. We we should learn all the facts about treating adult eye diseases.

Common Names: Siberian fritillary, Pale-Flowered Fritillary Habitat : Fritillaria pallidiflora is native to E. Asia – China to E. Siberia.(Xinjiang, Kyrgyzstan and Kazakhstan) It grows in the Alpine meadows, woods and scrub. Slopes in the sub-alpine zone. Forests, thickets, meadows, grassy slopes, mountain steppes, 1300 – 2500 metres in NW Xinjiang, China.
Fritillaria pallidiflora is a bulb growing to 0.6 m (2ft) by 0.1 m (0ft 4in) It is in flower from May to June. The flowers are yellow, and nodding (hanging downward).
CLICK & SEE THE PICTURES
The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects.Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers moist soil.
One of the best species in this genus for growing outdoors in Britain, it is easily grown in a moderately fertile well-drained soil so long as it is not allowed to dry out. Prefers a rich peaty soil in semi-shade. Another report says that it succeeds outdoors when grown in a bed of river sand and leafmould about 60cm deep. A very ornamental plant. Cultivated for medicinal use in China. Propagation:
Seed – best sown as soon as ripe in a cold frame, it should germinate in the spring. Protect from frost. Stored seed should be sown as soon as possible and can take a year or more to germinate. Sow the seed quite thinly to avoid the need to prick out the seedlings. Once they have germinated, give them an occasional liquid feed to ensure that they do not suffer mineral deficiency. Once they die down at the end of their second growing season, divide up the small bulbs, planting 2 – 3 to an 8cm deep pot. Grow them on for at least another year in light shade in the greenhouse before planting them out whilst dormant. Division of offsets in August. The larger bulbs can be planted out direct into their permanent positions, but it is best to pot up the smaller bulbs and grow them on in a cold frame for a year before planting them out in the autumn. Bulb scales. Medicinal Uses:
The bulbs are antitussive, expectorant, febrifuge and pectoral. They contain fritimine which lowers blood pressure, diminishes excitability of respiratory centres, paralyses voluntary movement and counters effects of opium. An infusion of the dried powdered bulb is used internally in the treatment of coughs, bronchitis, pneumonia, feverish illnesses, abscesses etc. The bulbs also have a folk history of use against cancer of the breast and lungs in China. This remedy should only be used under the supervision of a qualified practitioner, excessive doses can cause breathing difficulties and heart failure. The bulbs are harvested in the winter whilst they are dormant and are dried for later use. Disclaimer : The information presented herein is intended for educational purposes only.

Palmer hyperhidrosis is profuse perspiration (excessive sweating) of the palms.It is one form of focal hyperhidrosis, meaning profuse perspiration affecting one area of the body. Sweaty palms may be accompanied by profuse perspiration of the feet, forehead, ckeeks, armpits (axillae) or be part of general hyperhidrosis (profuse perspiration throughout the body). Hyperhidrosis refers to profuse perspiration beyond the body’s thermoregulatory (temperature control) needs.
Palmer hyperhidrosis is a common condition in which the eccrine (sweat) glands of the palms and soles secrete inappropriately large quantities of sweat. The condition may become socially and professionally debilitating. The condition usually is idiopathic and it begins in childhood and frequently runs in families.
The intensity of symptoms may vary among sufferers and trigger factors should be carefully noted. Common symptoms are :
*Perspiration of the hands can vary from mild clamminess to severe perspiration resulting in dripping sweat.
*Temperature differences of palmar surface compared to surface temperature of other parts of the body may be noted.
*Sloughing (peeling) of skin may be noted in profuse perspiration.
*Episodes of profuse perspiration may be followed by periods of extreme dryness on the palmar surface.
*Hyperhidrosis often starts in puberty, and family history is often reported.
The secondary effects of palmar hyperhidrosis can result in both psychosocial effects as well as difficulty in undertaking certain tasks or handling equipment. Sufferers of palmar hyperhidrosis are often reluctant to partake in socially expected actions like shaking hands or touching loved ones. The embarrassment of dealing with this condition can affect the level of interactivity in both social and work situations. Difficulties with holding objects, gripping equipment or soiling electronic devices like keyboards may affect functioning at work. Daily activities such as writing with a pen or counting cash notes is often difficult.
Causes: Hyperhidrosis is either primary focal or secondary generalized.
1. Primary Palmar Hyperhidrosis
Focal palmar hyperhidrosis is usually localized and is referred to as primary (essential, idiopathic), meaning no obvious cause, except strong family predisposition can be found (4,5), and affected persons are otherwise healthy . Sweating on other locations as feet, armpits and face may appear. Primary palmar hyperhidrosis is caused by overactivity of the sympathetic nervous system, primarily triggered by emotional causes including anxiety, nervousness, anger and fear .
There may be a significant reduction in perspiration during sleep or sedation.
2. Secondary Palmar Hyperhidrosis
In secondary palmar hyperhidrosis hands sweat due to an obvious underlying disorder like:
*Secondary palmar hyperhidrosis as part of generalized hyperhidrosis due to several hormonal causes (diabetes, hyperthyroidism, thyrotoxicosis, menstruation, menopause), metabolic disorders, malignant disease (lymphoma, pheochromocitoma), autoimmune disorders (rheumatoid arthritis, systemic lupus erythrematosus), drugs like hypertensive drugs and certain classes of antidepressants (list of medications causing hyperhidrosis), chronic use of alcohol, Parkinson’s disease, neurological disorders (toxic neuropathy), homocystinuria, plasma cell disorders. Detailed list of conditions causing generalyzed hyperhidrosis.
How Sweat Glands Work:
In eccrine glands, the major substance enabling impulse conduction is acetylcholine, and in apocrine glands, they are catecholamines.
Body temperature is controlled by the thermoregulatory center in the hypothalamus and this is influenced not only by by core body temperature but also by hormones, pyrogens, exercise and emotions.
Diagnosis: The first step in diagnosing the Palmar hyperhidrosis is to differentiate between generalized and focal hyperhidrosis.
A thorough case taking and medical history is usually sufficient to diagnose palmar hyperhidrosis and any trigger factors (scheduled drugs, narcotics, chronic alcoholism).
Diagnostic criteria for primary focal (including palmar) hyperhidrosis are:
*Bilateral and relatively symmetric sweating
*Frequency of at least 1 episode per week
*Impairment of daily activities
*Age at onset before 25 years
*Cessation of sweating during sleep
Tests may include:
*Hematological studies may be necessary to identify thyroid disorders (thyroid function test for T3 and T4 as well as thyroid antibodies) and diabetes (fasting blood glucose or a glucose tolerance test).
*X-rays and MRI scans will assist for diagnosing tuberculosis, pneumonia and tumors.
*Superficial electroconductivity can be monitored as any hyperhidrosis reduces skin electrical resistance.
*Thermoregulatory sweat test uses moisture-sensitive indicator powder to monitor moisture. Changes in the color of the powder at room temperature will highlight areas of increased perspiration.
Treatment: Conservative management should be coupled with prescribed treatment by the Doctor to reduce the symptoms.
*Counseling may be effective in managing primary palmar hyperhidrosis in cases of mental-emotional etiology.
*Trigger foods and aggravating factors should be noted if possible and relevant dietary changes should be implemented.
*Effective prevention of secondary palmar hyperhidrosis is difficult with conservative management and drug therapy or surgery may be required.
*Excessive physical activity and extremes of heat may be two trigger factors that should be avoided as far as possible.
*In cases of diabetes, a glucose controlled diet with low glycemic index may improve glucose tolerance which could assist with palmar hyperhidrosis.
*Abstinence from alcohol and narcotics is advisable if it is the causative factor for sweaty palms.
*Stimulants such as caffeine and nicotine may aggravate palmar hypehidrosis and should relevant dietary and lifestyle changes should be implemented.
*Anti-perspirant compounds like aluminum chloride can be applied on the palms to reduce moisture or palmar surfaces. Recent research on an aluminum sesquichlorohydrate foam has shown that it is effective in reducing sweat in palmar hyperhidrosis
Treatment remains a challenge: options include topical and systemic agents, iontophoresis, and botulinum toxin type A injections, with surgical sympathectomy as a last resort. None of the treatments is without limitations or associated complications. Topical aluminum chloride hexahydrate therapy and iontophoresis are simple, safe, and inexpensive therapies; however, continuous application is required because results are often short-lived, and they may be insufficient. Systemic agents such as anticholinergic drugs are tolerated poorly at the dosages required for efficacy and usually are not an option because of their associated toxicity. While botulinum toxin can be used in treatment-resistant cases, numerous painful injections are required, and effects are limited to a few months.
Standard therapeutic protocol may differ among cases of palmar hyperhidrosis depending on medical history and underlying pathology.
*Anticholinergic drugs have a direct effect on the sympathetic nervous system although there are numerous side effects.
*Treatment should be directed at contributing factors.
*Ionophoresis involves the use of electrotherapeutic measures to reduce the activity of sweat glands.
*Botulinum injections at the affected area may be useful for its anticholinergic effects.
*Surgery should be considered if drug therapy proves ineffective. Endoscopic transthoracic sympathectomy involves resection of the sympathetic nerve supply to the affected area. This prevents nerve stimulation of the sweat gland of the palms. However surgery has a host of complications including exacerbating the problem or increasing generalized hyperhidrosis.
Surgical sympathectomy should be reserved for the most severe cases and should be performed only after all other treatments have failed. Although the safety and reliability of treatments for palmoplantar hyperhidrosis have improved dramatically, side effects and compensatory sweating are still common, potentially severe problems.

Experts now say that stretching before exercise may actually harm you. ……Lenny Bernstein reports
It’s been a long, hard day at the office, and you need a good workout to blow off all that stress. But before you hit the free weights, the stationary bike or the elliptical machine, you spend 10 minutes carefully stretching all those stiff muscles, just as every coach, trainer and physical therapist has advised for as long as you can remember.
There’s no evidence that you’ll prevent injury. In fact, some people believe you’re more likely to cause one.
“There is not sufficient evidence to endorse or discontinue routine stretching before or after exercise to prevent injury among competitive or recreational athletes,” concluded the National Center for Injury Prevention Control, part of the Centers for Disease Control and Prevention, in a 2004 study that may be the most thorough look at the research on stretching.
Research and anecdotal information attribute many benefits to stretching: reduced muscle tension, improved circulation, pain reduction and management. Perhaps most important, stretching helps us maintain range of motion as we age, allowing older people to continue with the activities of daily living.
The question is whether “static stretching” — the most common type, which involves holding a muscle in one position for a defined period of time — has been misinterpreted, or oversold, as a preventive for what ails you.
“People believe all kinds of amazing things, and it changes every 10-15 years,” said William Meller, a physician and associate professor of evolutionary medicine at the University of California at Santa Barbara. The merits of stretching are “not based on any science. It’s spread by coaches, trainers and all kinds of people.”
According to Julie Gilchrist, a medical epidemiologist who helped conduct the CDC study, “it’s probably important that we maintain some norm of flexibility throughout our life spans, but I don’t think anyone has really defined what that (norm) is.
“Our belief is there are probably people who would benefit from stretching. But then the question is who should stretch, when to stretch,” how much to stretch and, most important, what benefits can be expected.
Even for the elderly, “we don’t have the kinds of controlled intervention studies that we need to make a definitive statement about the benefits of doing flexibility exercises,” said Chhanda Dutta, chief of the clinical gerontology branch at the National Institute on Aging.
Similarly, coaches wouldn’t dream of putting athletes on a field, even for practice, without a battery of stretches that help them take the pounding and awkward landings of contact sports.
“As a coach, if I didn’t do that and somebody got hurt, I would probably have a tough time sleeping at night,” said Paul Foringer, a football coach at a high school in Gaithersburg, Maryland. “It’s kind of common sense. If you take something that’s taut and tough and you yank it, you’re going to tear it.”
But that’s not what studies show. “Stretching was not significantly associated with a reduction in total injuries,” said the CDC study, “and similar findings were seen in the subgroup analyses.”
In static stretching, “you’re taking the muscle to the point where it naturally wants to go, and then you’re taking it a little bit farther,” said Meller. That produces microscopic tears of muscle fibres and does nothing to prevent injury, he said. It also may weaken the muscle slightly, increase the possibility of injury and inhibit performance, according to him and the CDC study.
For those who want to stretch, it should be done after a warm-up or at the end of an exercise routine because warm muscles are more pliable.
Research indicates that warming up before exercise is more valuable than stretching. Specifically, Meller said, you should spend three to five minutes gently putting your body through the actions you’re about to perform, slowly increasing the intensity. If you’re going to play tennis, he said, swing forehands, backhands and serves, and run forward, backward and laterally before you hit the first ball.
Middle-aged non-drinkers can quickly reduce their risk of heart disease by introducing a daily tipple to their diet, South Carolina researchers say.
……………..click & see Wine was found to have the biggest effect on heart disease
New moderate drinkers were 38% less likely to develop heart disease than those who stayed tee-total, a four-year study involving 7,500 people found.
Those who drank only wine showed the most benefit, the researchers reported in the American Medical Journal.
But cardiac experts warned alcohol was not a panacea for good heart health.
The results came from a study of 7,500 people taking part in a trial to look at risk factors for atherosclerosis – hardening of the arteries.
None of them drank alcohol at the start of the study but 6% began to drink moderate amounts – one drink per day or fewer for women and two drinks per day or fewer for men – during the course of the research.
The reduced cardiovascular risk remained when the researchers from the Medical University of South Carolina took into account physical activity, body mass index, demographic and cardiac risk factors.
There was no difference in deaths over the four-year follow up.
Those who stuck to wine had the biggest reduction in cardiovascular events, such as heart attacks, compared with non-drinkers, heavy drinkers or those who drank other types of alcohol.
The study also found some improvement in HDL or “good” cholesterol in those who took up drinking.
Despite several studies showing an association with alcohol intake and reduced cardiovascular risk, guidance from the American Heart Association warns people not to start drinking if they do not already drink alcohol.
Study leader Dana King said he was surprised that the effect was so large and so quick.
“For carefully selected individuals, a ‘heart healthy diet’ may include limited alcohol consumption even among individuals who have not included alcohol previously,” he said.
However, Dr King said the benefits had to be weighed with caution against known adverse effects of drinking alcohol and it would not be advised in some people such as those with liver problems or cancer.
“I know there’s concerns about binge drinking but that is not the type of drinking pattern we’re seeing here.
“When we say seven drinks a week, we mean one a day not seven drinks on a Saturday night.”
Judy O’Sullivan, cardiac nurse at the British Heart Foundation, said the study added to the evidence that alcohol in moderation provides some protection for the heart.
But she added: “Alcohol is not a medicine and it should not be used as a panacea.
“There is a fine line between moderation and excess and alcohol can pose as many threats as it does benefits.
“Non-drinkers should not take up alcohol to protect their heart based on this study alone.”
