Health Tips for March 1

Try Tea Tree Oil
For athlete's foot, reach for tea tree oil, an extract of the leaves of an Australian tree. It appears to have antiseptic properties and may work as well as or better than over-the-counter antifungal products. Apply a light coating of the oil to affected areas two to three times a day; continue for a week or two after symptoms disappear.

Take Tulsi
Research suggests that this Ayurvedic herb, also called holy basil, may help manage levels of the stress hormone cortisol, helping to boost your mood. Look for teas and supplements in health-food stores and follow package directions.

Eat Avocados
For dry skin, incorporate more avocados into your diet. They're rich in monounsaturated fat and vitamin E, both of which promote healthy skin. Try them on salads and sandwiches, and even in smoothies.

Keep Echinacea Close
If you feel a cold coming on, consider reaching for this age-old remedy. A 2007 meta-analysis showed that the herb can reduce cold symptoms. Aim for three grams daily in tincture or capsule form, starting at the first sign of symptoms.

Invest in a Neti Pot
Plagued with sinus problems? Rinse your nasal passages twice a day to flush out pollen and other irritants. Put saline solution (a 1/4 teaspoon salt and 1 cup warm water) in a plastic squirt bottle or a nasal irrigator, a spouted container that allows you to pour water directly into your nose. The solution should fill your nasal cavity and spill out the other nostril. Gently blow your nose afterward.

Health Tips for February 28

Eat Bananas
People whose diets are rich in potassium may be less prone to high blood pressure. Besides reducing sodium and taking other heart-healthy steps, eat potassium-packed picks such as bananas, cantaloupe, and oranges.

Love Lavender
To ease stress and prepare for bed, soak in a hot bath spiked with a few drops of lavender essential oil. Play soothing music while you bathe to unwind further.

Keep Capsaicin Cream on Hand
For sore muscles and joints, apply a cream or ointment that contains capsaicin, the active ingredient in chile peppers, two or three times a day. The heat from the peppers has been shown to help relieve pain.

Get a Massage
Certain trigger points -- spots of tension in musculoskeletal tissue -- can cause back pain. Ask a massage therapist or other bodyworker who specializes in myofascial release or neuromuscular therapy to focus on these points during a massage.

Go for Garlic
Adding raw or lightly cooked garlic and onions to your meals may help keep you healthy this winter. Both foods appear to possess antiviral and antibacterial properties and are believed to boost immunity.

Health Tips for February 27

Sniff Rosemary
According to some research, catching a whiff of this aromatic herb may increase alertness and improve memory. To stay sharp, try smelling fresh rosemary or inhaling the scent of rosemary essential oil before a test or meeting.

Embrace Bitters
Combat a yen for sugar by following a Chinese medicine approach: Eat foods such as endive, radicchio, cooked greens, and olives.

Fish for Dry Eyes?
If you suffer from dry eyes, up your seafood intake. Salmon, sardines, and mackerel contain omega-3 fatty acids, which the body uses to produce tears, among other things. Research suggests that people who consume higher amounts of these fats are less likely to have dry eyes.

Pop a Probiotic
To keep yeast infections at bay, head for the vitamin aisle. Supplementing with "good" bacteria (for example, Lactobacillus or Bifidobacterium) may help restore the balance the of bacteria living in the female genital tract and inhibit the growth of yeast in women with recurrent infections. Foods such as naturally fermented sauerkraut, kimchi, and kefir, as well as yogurt with active cultures, also contain these bacteria.

Benefit From Bilberry
Studies are mixed, but some have found that bilberry, a relative of the blueberry, may improve night vision. During World War II, fighter pilots reported better night vision after eating bilberry jam. Take 25 to 50 milligrams of bilberry extract; expect best results within the first few hours.

Health Tips for February 26

Oolong Tea for Eczema
Research suggests that people with mild eczema who drink oolong tea three times a day may show improvement in itching and other symptoms. Compounds in the tea called polyphenols appear to be responsible.

Herbal Treatment for Varicose Veins
For varicose veins, try horse chestnut, an herbal extract that's been shown in studies to strengthen veins and reduce swelling. The herb is also available in topical creams, though there's not as much evidence for these.

Tame Tension Headaches
Tame tension headaches by rubbing peppermint oil, Tiger Balm, or white flower oil into your temples. All three remedies contain menthol, which has analgesic properties.

Ginger for Congestion
The volatile oils in ginger have long made it a useful herbal remedy for nasal and chest congestion. Pour 2 cups of boiling water over a 1-inch piece of peeled, grated ginger; steep for 10 minutes; and strain. Add a pinch or two of cayenne pepper to the water and drink as needed.

Get a Good Pair of Sneakers
Is your energy lagging? Though it may be the last thing you feel like doing when you're tired, exercise -- even a brisk walk -- can be more effective than a nap or cup of coffee at fighting fatigue.

Mediterranean Diet's Benefits Confirmed

The Mediterranean diet has long been touted as healthy. Now a study released Monday of the effects of a diet rich in olive oil, nuts, vegetables, fruits and fish confirms that.

The study, published in the New England Journal of Medicine, showed that the diet can reduce the risk of stroke and other cardiovascular diseases by 30 percent.

Such a diet may seem like common sense, but researchers say the findings are significant because of the study's size and scientific rigor. It followed more than 7,400 people at risk of heart disease for nearly five years and measured the effects of the Mediterranean diet against a group that was assigned a low-fat diet.

"This study backs up what we thought we knew with science, and the results were pretty dramatic," said Dr. Rita Redberg, a UCSF cardiologist specializing in heart disease in women. "If this were a pill, people would be clamoring for it."

Redberg, who was not involved with the study, said one of the diet's main benefits is that it's not only heart-healthy, but it also promotes a way of eating that people can follow for a lifetime rather than just a few months. "This is a diet that's pretty doable, particularly for people living in Northern California, where we certainly have access to plenty of fruits and vegetables and grains," she said.

High-risk group

The study, which was conducted in Spain, involved people between 55 and 80 who did not have heart disease but were at risk of developing cardiovascular problems because of various factors, such as being overweight, smoking, having a family history of the disease, or having high blood pressure or high cholesterol.

Participants were assigned to one of three groups. People in two of the groups were required to follow a Mediterranean diet - in other words, meals rich in vegetables, fruit, fish and legumes. Those in the Mediterranean diet groups were instructed to add at least 4 tablespoons a day of extra-virgin olive oil to their daily diet. Those in the other group supplemented their meals with a combined ounce of walnuts, almonds and hazelnuts each day.

Participants in the control group, which was being compared against the groups eating the Mediterranean diet, were encouraged to lower their fat intake by eating lean meats and low-fat dairy products. Midway through the study, its authors said, they intervened to offer more specific guidance about what the participants should eat and how to prepare their foods.

Clear results

The results were so clear that the study was ended early. The two groups assigned to the Mediterranean diet had fairly similar results, with 3.4 percent of the group that ate extra nuts suffering major cardiovascular problems, compared with 3.8 percent in the olive-oil group.

Meanwhile, 4.4 percent of participants in the control group had major cardiovascular problems. Reduced stroke risk, rather than lower heart attack risk, accounted for most of the difference between the Mediterranean groups and the low-fat group.

While the findings were heralded by many in the health care community, not everyone was impressed.

Dr. Dean Ornish, UCSF professor and president of the nonprofit Preventive Medicine Research Institute in Sausalito, criticized the study, contending that the control group was not monitored carefully enough and wasn't assigned a truly low-fat diet.

"A Mediterranean diet is a healthier diet than what most people are eating," Ornish said. "The problem is they claim (the study) was comparing it to a low-fat diet, and it wasn't."

Ornish said the American Heart Association recommends a diet with fewer than 30 percent of calories coming from fat, but the control group's levels edged closer to 40 percent. Ornish, who promotes his own heart-healthy diet, urges people trying to reverse the effects of heart disease to cut that figure to as low as 10 percent.

Easy to follow

Dr. Cesar Molina, co-founder of the South Asian Heart Center at El Camino Hospital in Mountain View, said the study promotes a diet that people can easily follow.

"You just have two fists of cooked vegetables per day; one fist - or the size of a tennis ball - serving of fruit each day," he said. He advised people to make olive oil their primary choice of dietary oil and have about 12 nuts daily - preferably walnuts, because they are a source of the healthful omega-3 fatty acid.

The study noted that some authors had financial ties to food, wine and other industry groups, and foods were supplied by olive oil and nut producers in Spain, as well as the California Walnut Commission.

Dennis Balint, chief executive officer of the California Walnut Commission, said walnut growers represented by his group provided a daily half-ounce of walnuts to the group that supplemented the Mediterranean diet with nuts.

Balint said he was surprised by the magnitude of the study's results, but not that the diet with nuts proved healthful. "Every nut has its strong suit. Our strong suit is the fact that walnuts have plant-based omega-3," he said.

What to Keep in a First Aid Kit

A Proper Container
Your first aid kit should be portable and easily accessible. A small plastic tackle box or art supply box makes a good first aid kit, or you can use something as simple as a resealable freezer bag.

Where to Store Your First Aid Kit
Keep your home first aid kit in a central location so that it will be accessible during emergencies. Remember to keep it out of reach of small children. It's a good idea to maintain two different first aid kits: one for the home, and another for the car. Some practical places to store first aid kits include:

  • bathroom or kitchen cabinet
  • car (glove compartment is most accessible)
  • workshop
  • garage

The Most Important Item for a Car First Aid Kit
Your car first aid kit must have a cellular phone. There is no better tool in the event of an emergency.

Cellular phones must have enough battery power to turn the phone on, but you don't need a current contract with a service provider to call 9-1-1: federal law mandates that cell phones must be able to reach 9-1-1 anytime the number is dialed, regardless of the service agreement. So take your old cell phone that you don't use anymore and put it in your first aid kit for emergencies. If you don't have an old cell phone, you can find one via various programs that unite old, unused cell phones with people who need them for emergencies.

Items for Your First Aid Kit

  • first aid manual
  • acetaminophen
  • ibuprofen
  • tweezers
  • splint
  • alcohol wipes
  • antiseptic wipes
  • antiseptic hand cleanser
  • medical adhesive tape
  • sterile gauze (four inch squares are best)
  • elastic bandages
  • thermometer
  • flashlight and extra batteries
  • several sizes of adhesive bandages
  • insect bite swabs
  • triple antibiotic ointment
  • hydrocortisone cream
  • safety pins
  • calamine lotion
  • hydrogen peroxide
  • bandage scissors
  • triangular bandages
  • instant cold packs
  • exam gloves
  • barrier device for CPR
  • list of emergency phone numbers and important family medical info
  • blanket (stored nearby)

After You've Stocked Your First Aid Kits

  • Read the entire first aid manual so you'll understand how to use the contents of your kits. (If your kids are old enough to understand, review the manual with them.)
  • Check the kits regularly. Replace missing items or medicines that may have expired.
  • Check the flashlight batteries to make sure they work.
  • If you're flying, be sure to pack the first aid kit in your checked luggage. Many of the items won't be permitted in your carry-on bags.

Health Tips for February 20

Trying to Conceive?
Avoid all alcohol/drug use when trying to conceive, in case you do get pregnant.

Living with Peripheral Vascular Disease (PVD)
Avoid "cured meats." They contain nitrates and nitrites which can make your PVD much worse.

Want Healthy Kidneys?
Your kidney's job is to filter your blood. Drinking enough pure water will help them function better.

Depressed?
Depression can be caused by undiagnosed thyroid disease. Make sure your MD checks you for it.

Healthy Cooking Tip
Boil or poach your eggs to preserve the nutritional content of the fats and vitamins within them.

How to tell a cold from the flu

The common cold and flu are caused by different viruses but can have some similar symptoms, making them tough to tell apart. In general, the flu is worse and symptoms are more intense.

COLDS: Usual symptoms include stuffy or runny nose, sore throat and sneezing. Coughs are hacking and productive. It's unusual to have fever, chills, headaches and body aches, and if they do occur, they are mild.

FLU: Fever is usually present, along with chills, headache and moderate-to-severe body aches and tiredness. Symptoms can come on rapidly, within three to six hours. Coughs are dry and unproductive, and sore throats are less common.

PREVENTION: To avoid colds and flu, wash your hands with warm water and soap after you've been out in public or around sick people. Don't share cups or utensils. And get a flu vaccination — officials say it's not too late, even in places where flu is raging.

TREATMENT: People with colds or mild cases of the flu should get plenty of rest and fluids. Those with severe symptoms, such as a high fever or difficulty breathing, should see a doctor and may be prescribed antiviral drugs or other medications. Children should not be given aspirin without a doctor's approval.

Facts About Alcoholism and Alcohol Abuse

  • Alcohol abuse is a disease that is characterized by the sufferer having a pattern of drinking excessively despite the negative effects of alcohol on the individual's work, medical, legal, educational, and/or social life.
  • Alcohol abuse affects about 10% of women and 20% of men in the United States, most beginning by their mid teens.
  • Signs of alcohol intoxication include the smell of alcohol on the breath or skin, glazed or bloodshot eyes, the person being unusually passive or argumentative, and/or a deterioration in the person's appearance or hygiene.
  • Almost 2,000 people under 21 years of age die each year in car crashes in which underage drinking is involved. Alcohol is involved in nearly half of all violent deaths involving teens.

  • While some people with alcohol dependence can cut back or stop drinking without help, most are only able to do so temporarily unless they get treatment.
  • There is no amount of alcohol intake that has been proven to be generally safe during pregnancy.
  • The long-term effects of alcohol abuse and alcoholism can be devastating and even life threatening, negatively affecting virtually every organ system.
  • Codependency is the tendency to interact with another person in an excessively passive or caretaking manner that negatively affects the quality of the codependent individual's life.

Physical warning signs of drug abuse

  • Bloodshot eyes, pupils larger or smaller than usual.
  • Changes in appetite or sleep patterns.
  • Sudden weight loss or weight gain.
  • Deterioration of physical appearance, personal grooming habits.
  • Unusual smells on breath, body, or clothing.
  • Tremors, slurred speech, or impaired coordination.

Behavioral signs of drug abuse

  • Engaging in secretive or suspicious behaviors.
  • Sudden change in friends, favorite hangouts, and hobbies.
  • Frequently getting into trouble (fights, accidents, illegal activities).

Psychological warning signs of drug abuse

  • Unexplained change in personality or attitude.
  • Sudden mood swings, irritability, or angry outbursts.
  • Periods of unusual hyperactivity, agitation, or giddiness.
  • Lack of motivation; appears lethargic or “spaced out.”

5 Myths About Drug Abuse and Addiction

MYTH 1: Overcoming addiction is a simply a matter of willpower. You can stop using drugs if you really want to. Prolonged exposure to drugs alters the brain in ways that result in powerful cravings and a compulsion to use. These brain changes make it extremely difficult to quit by sheer force of will.

MYTH 2: Addiction is a disease; there’s nothing you can do about it. Most experts agree that addiction is a brain disease, but that doesn't mean you’re a helpless victim. The brain changes associated with addiction can be treated and reversed through therapy, medication, exercise, and other treatments.

MYTH 3: Addicts have to hit rock bottom before they can get better. Recovery can begin at any point in the addiction process—and the earlier, the better. The longer drug abuse continues, the stronger the addiction becomes and the harder it is to treat. Don’t wait to intervene until the addict has lost it all.

MYTH 4: You can’t force someone into treatment; they have to want help. Treatment doesn't have to be voluntary to be successful. People who are pressured into treatment by their family, employer, or the legal system are just as likely to benefit as those who choose to enter treatment on their own. As they sober up and their thinking clears, many formerly resistant addicts decide they want to change.

MYTH 5: Treatment didn't work before, so there’s no point trying again. Recovery from drug addiction is a long process that often involves setbacks. Relapse doesn't mean that treatment has failed or that you’re a lost cause. Rather, it’s a signal to get back on track, either by going back to treatment or adjusting the treatment approach.

Signs and Symptoms of Drug Abuse and Addiction

Common signs and symptoms of drug abuse
  • You're neglecting your responsibilities at school, work, or home (e.g. flunking classes, skipping work, neglecting your children) because of your drug use.
  • You're using drugs under dangerous conditions or taking risks while high, such as driving while on drugs, using dirty needles, or having unprotected sex.
  • Your drug use is getting you into legal trouble, such as arrests for disorderly conduct, driving under the influence, or stealing to support a drug habit.
  • Your drug use is causing problems in your relationships, such as fights with your partner or family members, an unhappy boss, or the loss of old friends.
Common signs and symptoms of drug addiction
  • You've built up a drug tolerance. You need to use more of the drug to experience the same effects you used to attain with smaller amounts.
  • You take drugs to avoid or relieve withdrawal symptoms. If you go too long without drugs, you experience symptoms such as nausea, restlessness, insomnia, depression, sweating, shaking, and anxiety.
  • You've lost control over your drug use. You often do drugs or use more than you planned, even though you told yourself you wouldn't. You may want to stop using, but you feel powerless.
  • Your life revolves around drug use. You spend a lot of time using and thinking about drugs, figuring out how to get them, and recovering from the drug’s effects. You've abandoned activities you used to enjoy, such as hobbies, sports, and socializing, because of your drug use.
  • You continue to use drugs, despite knowing it's hurting you. It’s causing major problems in your life—blackouts, infections, mood swings, depression, paranoia—but you use anyway.

Causes of Bed Sores

Bed sores, also called pressure sores or decubitus ulcers, are caused by pressure against the skin that inhibits an adequate supply of blood to skin and underlying tissues. Other factors related to limited mobility can make the skin vulnerable to damage and contribute to the development of pressure sores. There are three primary contributing factors:

Sustained pressure. When your skin and the underlying tissues are trapped between bone and a surface such as a wheelchair or bed, the pressure may be greater than the pressure of the blood flowing in the tiny vessels (capillaries) that deliver oxygen and other nutrients to tissues. Deprived of these essential nutrients, cells of the skin and other tissues are damaged and may eventually die. This kind of pressure tends to happen in areas that aren't well padded with muscle or fat and that lie just over a bone, such as your spine, tailbone (coccyx), shoulder blades, hips, heels and elbows.

Friction. Friction is the resistance to motion. When a person changes position or is handled by care providers, friction may occur when the skin is dragged across a surface. The resistance to motion may be even greater if the skin is moist. Friction between skin and another surface may make fragile skin more vulnerable to injury.

Shear. Shear occurs when two surfaces move in the opposite direction. For example, when a hospital bed is elevated at the head, a person can slide down in bed. As the tailbone moves down, the skin over the bone may stay in place — essentially pulling in the opposite direction. This motion may damage tissue and blood vessels, making the site more vulnerable to damage from sustained pressure.
