Antioxidants against Cell Damaging

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. They are also available as dietary supplements. Examples of antioxidants include
-Beta-carotene
-Lutein
-Lycopene
-Selenium
-Vitamin A
-Vitamin C
-Vitamin E

Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet with lots of vegetables and fruits is healthy and lowers risks of certain diseases. But it isn’t clear whether this is because of the antioxidants, something else in the foods, or other factors.
High-dose supplements of antioxidants may be linked to health risks in some cases. For example, high doses of beta-carotene may increase the risk of lung cancer in smokers. High doses of vitamin E may increase risks of prostate cancer and one type of stroke. Antioxidant supplements may also interact with some medicines. To minimize risk, tell you of your health care providers about any antioxidants you use.






What is a Stent?

A stent is a small, expandable tube. It is permanently inserted into the artery during angioplasty. The stent keeps the artery open.
During angioplasty, the balloon is placed inside the stent and inflated, which opens the stent and pushes it into place against the artery wall to keep the narrowed artery open. Because the stent is like woven mesh, the cells lining the blood vessel grow through and around the stent to help secure it. Your doctor may use a bare metal stent or a drug-eluting stent.
Drug-eluting stents. All stents have a risk that scar tissue will form and narrow the artery again. This scar tissue can block blood flow. To help prevent this blockage, drug-eluting stents are coated with drugs that prevent the scar tissue from growing into the artery. Drug-eluting stents may lower the chance that you will need a second procedure (angioplasty or surgery) to open the artery again.
A stent is designed to:
-Press the plaque against the artery walls and open up the artery, thereby improving blood flow.
-Keep the artery open after the balloon is deflated and removed.
-Seal any tears in the artery wall.
-Prevent the artery wall from collapsing or closing off again (restenosis).
-Prevent small pieces of plaque from breaking off, which might cause a heart attack.






Evaluating MRI Scan Results

First, the difficulty with the results of an MRI scan, as with many other diagnostic studies, is that the “abnormality” that shows up on the MRI scan may not actually be the cause of back pain. Numerous clinical studies have shown that approximately 30% of individuals in their thirties and forties have a lumbar disc herniation on their MRI scan, although they do not have any back pain.
Therefore, an MRI scan cannot be interpreted on its own. Everything seen on an MRI needs to be well-correlated to the individual patient’s situation, including:
-Symptoms (such as the duration, location, and severity of pain)
-Any neurological deficits on their physical examination
Another important consideration with MRI scans is the timing of when the scan is done. The only time an MRI scan is needed immediately is when a patient has either:
-Bowel or bladder incontinence
-Progressive weakness in the legs due to nerve damage.
Fortunately, both of the above situations are rare.






Signs of Peripheral Artery Disease

The classic symptoms are pain, achiness, fatigue, burning, or discomfort in the muscles of your feet, calves, or thighs. These symptoms usually appear during walking or exercise and go away after several minutes of rest.
-At first, these symptoms may appear only when you walk uphill, walk faster, or walk for longer distances.
-Slowly, these symptoms come on more quickly and with less exercise.
Your legs or feet may feel numb when you are at rest. The legs also may feel cool to the touch, and the skin may look pale.
When peripheral artery disease becomes severe, you may have:
-Impotence
-Pain and cramps
at night
-Pain or tingling in the feet or toes, which can be so severe that even the weight of clothes or bed sheets is painful
-Pain that is worse when you raise the leg and improves when you dangle your legs over the side of the bed
-Skin that looks dark and blue
-Sores that do not heal






Stress Therapy

Frequent use of a personal computer and sitting at your desk for extended periods of time can cause chronic physical problems that you can hardly imagine. Neck and shoulder stiffness can lead to chronic headaches, numbness and weakness in the limbs and joints and eventually progress to Repetitive Strain Injuries (RSI) or work-related musculoskeletal disorders. These common ailments affect many of us who work long hours and more than 60% of us don’t receive the correct therapies and treatments.
RSI is treatable with physiotherapy, and Computer Stress Therapy has been created to relieve stressed musculoskeletal areas. Using our myofascial relief technique, soft tissue release, and upper body massage with superficial heat applied on the whole arm, Stress Therapy can help to increase blood circulation and relieve tension that manifests itself in the upper body. The treatment ends by applying an herbal compress to the eyes and facial area to relax soft tissue around the eyes.

When We Stop Breathing at Night…

The most common type of sleep apnea is called obstructive sleep apnea. It happens because the muscles in your throat relax, blocking the flow of air to your lungs. Your airway might be completely blocked or only partly blocked. When you stop breathing, the amount of oxygen in your blood drops. Your brain recognizes this and makes your body start breathing again.
If you have sleep apnea, there are times during the night when you stop breathing for 10 seconds or longer.

Your doctor needs to know how often there is a pause in your breathing. This helps to determine how severe your problem is. You might be asked to stay overnight in a sleep laboratory. Or your doctor might ask you to have your breathing measured at home.
Here’s one guide that doctors use:
-If your breathing is affected between five and 15 times an hour, you have mild sleep apnea.
-If your breathing is affected between 16 and 30 times an hour, you have moderate sleep apnea.
-If your breathing is affected more than 31 times an hour, you have severe sleep apnea.

People with severe sleep apnea may be at an increased risk of high blood pressure, heart disease and stroke and dying early.






Why Sex is Good for your Brain… and More?

Having more sex could not only make us feel good, it could provide far-reaching health benefits.
Unfortunately we are having less of it – on average we have sex fewer than five times a month, compared to six-and-a-half times 20 years ago, according to the National Survey of Sexual Attitudes and Lifestyles.
Yet studies have linked regular sexual activity to emotional well-being, reduced migraine pain and even a lower risk of prostate cancer.
A Canadian study last month found that half-an-hour of sexual activity could burn more calories than walking on a treadmill – the researchers claimed sexual activity could be considered significant exercise.
The study measured the sexual activity of 21 couples aged between 18 and 35 – they were monitored using an armband to calculate how many calories the wearer burned, and the intensity of the activity.
In a typical session lasting 25 minutes, the men burned an average of 100 calories, the women 69. The intensity of the activity was measured in METs (the Metabolic Equivalent of a Task); for men, the average reading was six METs, for women it was 6.6.
It’s roughly the same as playing doubles tennis, or walking uphill, for 20 minutes, 33 minutes of golf on a driving range, 40 minutes of yoga or 19 minutes of light rowing.
The Canadian findings chime with past campaigns by the British Heart Foundation, which suggested that 30 minutes of daily sex is as good for you as walking the dog.
Indeed, research is now showing that sex provides a ‘triple-whammy’ of benefits by combining a workout for the heart and lungs, the release of hormones that could lower stress and the production of new brain cells. And – for women – the added plus is a toning effect on the muscles in the pelvic floor.
Graham Jackson, a consultant cardiologist and president of The Sexual Advice Association, says we’ve known for a long time that sex has health benefits, but it’s only in the past decade that the taboo has been lifted from sex research in Britain… and the World.






How’s that Pain in the Neck?

Neck pain is discomfort in any of the structures in the neck. These include the muscles, nerves, bones (vertebrae), and the disks between the bones.
When your neck is sore, you may have difficulty moving it, especially turning to one side. Many people describe this as having a stiff neck. If neck pain involves nerves, you may feel numbness, tingling, or weakness in your arm, hand, or elsewhere.
Home Care
For minor, common causes of neck pain:
-Take over-the-counter pain relievers such as ibuprofen (Advil, Motrin IB) or acetaminophen (Tylenol).
-Apply heat or ice to the painful area. Use ice for the first 48 to 72 hours, then use heat after that. Heat may be applied with warm showers, hot compresses, or a heating pad. To prevent injuring your skin, do not fall asleep with a heating pad or ice bag in place.
-Stop normal physical activity for the first few days. This helps calm your symptoms and reduce inflammation.
-Do slow range-of-motion exercises, up and down, side to side, and from ear to ear. This helps to gently stretch the neck muscles.
-Have a partner gently massage the sore or painful areas.
-Try sleeping on a firm mattress without a pillow or with a special neck pillow.
-Ask your health care provider about using a soft neck collar to relieve discomfort. Do not use the collar for a long time. Doing so can make your neck muscles weaker.
You may want to reduce your activity only for the first couple of days. Then slowly resume your usual activities. Do not do any heavy lifting or twisting of your back or neck for the first 6 weeks after the pain begins. After 2 to 3 weeks, slowly begin exercising again. A physical therapist can help you decide when to begin stretching and strengthening exercises and how to do them.






Does Anxiety can Cause Asthma?

Some people worry that anxiety causes asthma. There is currently no evidence that anxiety can create asthma in those that did not originally have the condition. But there is a great deal of evidence that anxiety can worsen asthma symptoms.
It’s not clear why anxiety produces an increase in asthma symptoms, but the issue is fairly documented. The most likely reasons include:
Hyperventilation – Anxiety changes breathing habits. Many studies have shown that hyperventilation, whether it’s caused by a disorder (like anxiety) or no disorder at all, appears to increase the likelihood of an asthma attack. So those with anxiety that may be more prone to hyperventilating may be unintentionally forcing their own attack symptoms.
Inflammation – Stress can lead to inflammation. Asthma is the inflammation of airways. It’s unlikely that stress causes the inflammation that leads to asthma, but it’s possible that stress makes it harder to control inflammation when your asthma symptoms are acting up.
General Physiological Changes – On a physical level, stress does cause some issues that may contribute to asthma. For example, anxiety can release an excess of histamine (the chemical that causes allergies) that can lead to asthma attacks. Stress may also weaken your immune system in such a way that you become more vulnerable to viruses and external asthma triggers.
Muscle Constriction – Muscle constriction is also very common with anxiety. Muscle constriction can lead to tighter chest and other issues that may trigger asthma.
It doesn’t appear that asthma can be caused by anxiety, but there are strong indications that anxiety can make it much worse, especially if you are living with persistent anxiety or stress.






Symptoms of Exercise Headaches

Exercise headaches occur during or after sustained, strenuous exercise. Activities associated with exercise headaches include running, rowing, tennis, swimming and weightlifting.
Primary exercise headaches
These headaches:
-Are usually described as throbbing
-Occur during or after strenuous exercise
-Affect both sides of the head in most cases
Secondary exercise headaches
These headaches may cause:
-The same symptoms as primary exercise headaches
-Vomiting
-Loss of consciousness
-Double vision
-Neck rigidity

Primary exercise headaches typically last between five minutes and 48 hours, while secondary exercise headaches usually last at least a day and sometimes linger for several days or longer.
When to see a doctor- If you experience a headache during or after exercise, consult your doctor. Call your doctor right away if the headache begins abruptly or if it’s your first headache of this type.
