Caffeine may boost long-term memory

Numerous studies have suggested that caffeine has many health benefits. Now, new research suggests that a dose of caffeine after a learning session may help to boost long-term memory. This is according to a study published in the journal Nature Neuroscience.
The research team, led by Daniel Borota of the Johns Hopkins University in Baltimore, notes that although previous research has analyzed the effects of caffeine as a cognitive enhancer, whether caffeine can impact long-term memory has not been studied in detail.
To find out, the investigators analyzed 160 participants aged between 18 and 30 years.
On the first day of the study, the participants were shown pictures of different objects and were asked to identify them as "indoor" or "outdoor" items.
Soon after this task, they were randomized to receive either 200 mg of caffeine in the form of a pill, or a placebo tablet.
The next day, the participants were shown the same pictures as well as some new ones. The researchers asked them to identify whether the pictures were "new," "old" or "similar to the original pictures."

200 mg of caffeine 'enhanced memory'

From this, the researchers found that subjects who took the caffeine were better at identifying pictures that were similar, compared with participants who took the placebo.
However, the researchers note that both groups were able to accurately distinguish whether pictures were old or new.

New research suggests that consuming 200 mg of caffeine a day may boost long-term memory.
The team conducted further experiments using 100 mg and 300 mg doses of caffeine. They found that performance was better after the 200 mg dose, compared with the 100 mg dose, but there was no improvement after the 300 mg of caffeine, compared with 200 mg.
"Thus, we conclude that a dose of at least 200 mg is required to observe the enhancing effect of caffeine on consolidation of memory," the study authors write.
The team also found that memory performance was not improved if subjects were given caffeine 1 hour before carrying out the picture identification test.
They investigators say there are many possibilities as to how caffeine may enhance long-term memory.
For example, they say it may block a molecule called adenosine, preventing it from stopping the function of norepinephrine - a hormone that has been shown to have positive effects on memory.
They note that further research should be conducted to better understand the mechanisms by which caffeine affects long-term memory.
They add:
"Given the widespread use of caffeine and the growing interest in its effects both as a cognitive enhancer and as a neuroprotectant, these questions are of critical importance."

Potential benefits and risks of caffeine consumption

According to the latest figures from the US Food and Drug Administration (FDA), the average American consumes 300 mg of caffeine a day. The main sources of the compound are coffee, tea and soft drinks.
Many studies have suggested that caffeine offers health benefits. Last year, Medical News Today reported on a study suggesting that caffeinated drinks may reduce the risk of liver disease, while another study says drinking 2-4 cups of coffee a day may reduce suicide risk.
But it is not all good news. One study suggests that the stimulant is able to disrupt sleep patterns hours after consuming it, while another proposes that caffeine from energy drinks may alter heart function.

Cosway 7 smile Slow Juicer Review

Retains 100% of the essential nutrients and natural taste of fruit and vegetable juices for optimal health.

Easy and convenient way to get your 5 servings of fruits and vegetables every day!

Developed with unique technology, the Slow Juicer produces more juice than conventional juicers and better retains all the "live" nutrients, essential vitamins and enzymes.

Great for all kinds of fruits, vegetables, wheat grass, beans, and nuts!

Slow Juicer Features:

Continuous, clog–free operation – Pulp is automatically separated and pushed through a different outlet to allow for continuous juicing. There is no need to stop juicing to remove and discard the overflowing or clogged pulp. Just pour water through the feed chute for rinsing. Juicing can even continue with different types of fruits or veggies! The tastes don’t get mixed and the process is easy, convenient and hassie–free.

Low Speed Technology System (LIST) – Extraction is done at a low speed of 47 RPM with an ambient temperature so as not to disrupt the cellular structure of fruits and vegetables. This prevents oxidation and separation of the juices and produces 100% pure "living" juice that is filled with essential vitamins, nutrients and enzymes. It maintains the food’s natural flavor and color.

Unique method of pushing, pressing & squeezing – The special extraction process does not violently shred or disrupt the properties of the food, yet it actually extracts more juice than conventional juicers.

Conventional Juicers

High speed rotation and grinding – High heat is produced that disrupts the cellular structure of fruits and vegetables and allows oxidation (and loss of essential nutrients) because it exposes much of the juice’s surface to air.

Juice extraction with graters and blades – Can’t extract all of the juice from fruits and vegetables. (Just notice how wet the leftover pulp is).

Pulp accumulations in the juicer – The operation is slowed down because the pulp accumulates and clogs the juicer. The juicing process needs to be stopped to remove the pulp.

Laughter is good for your health

Humor & Laughter: Health Benefits & Online Sources

Humor is infectious. The sound of roaring laughter is far more contagious than any cough, sniffle, or sneeze. When laughter is shared, it binds people together and increases happiness and intimacy. Laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use

Laughter is strong medicine for mind and body

“Your sense of humor is one of the most powerful tools you have to make certain that your daily mood and emotional state support good health.”
~ Paul E. McGhee, Ph.D.
Laughter is a powerful antidote to stress, pain, and conflict. Nothing works faster or more dependably to bring your mind and body back into balance than a good laugh. Humor lightens your burdens, inspires hopes, connects you to others, and keeps you grounded, focused, and alert.
With so much power to heal and renew, the ability to laugh easily and frequently is a tremendous resource for surmounting problems, enhancing your relationships, and supporting both physical and emotional health.


Laughter is good for your health

  • Laughter relaxes the whole body. A good, hearty laugh relieves physical tension and stress, leaving your muscles relaxed for up to 45 minutes after.
  • Laughter boosts the immune system. Laughter decreases stress hormones and increases immune cells and infection-fighting antibodies, thus improving your resistance to disease.
  • Laughter triggers the release of endorphins, the body’s natural feel-good chemicals. Endorphins promote an overall sense of well-being and can even temporarily relieve pain.
  • Laughter protects the heart. Laughter improves the function of blood vessels and increases blood flow, which can help protect you against a heart attack and other cardiovascular problems.

Laughter and humor help you stay emotionally healthy

Laughter makes you feel good. And the good feeling that you get when you laugh remains with you even after the laughter subsides. Humor helps you keep a positive, optimistic outlook through difficult situations, disappointments, and loss.
More than just a respite from sadness and pain, laughter gives you the courage and strength to find new sources of meaning and hope. Even in the most difficult of times, a laugh–or even simply a smile–can go a long way toward making you feel better. And laughter really is contagious—just hearing laughter primes your brain and readies you to smile and join in the fun.

The link between laughter and mental health

The link between laughter and mental health
  • Laughter dissolves distressing emotions. You can’t feel anxious, angry, or sad when you’re laughing.
  • Laughter helps you relax and recharge. It reduces stress and increases energy, enabling you to stay focused and accomplish more.
  • Humor shifts perspective, allowing you to see situations in a more realistic, less threatening light. A humorous perspective creates psychological distance, which can help you avoid feeling overwhelmed.

The social benefits of humor and laughter

Humor and playful communication strengthen our relationships by triggering positive feelings and fostering emotional connection. When we laugh with one another, a positive bond is created. This bond acts as a strong buffer against stress, disagreements, and disappointment.

Laughing with others is more powerful than laughing alone

Creating opportunities to laugh

  • Watch a funny movie or TV show.
  • Go to a comedy club.
  • Read the funny pages.
  • Seek out funny people.
  • Share a good joke or a funny story.
  • Check out your bookstore’s humor section.
  • Host game night with friends.
  • Play with a pet.
  • Go to a “laughter yoga” class.
  • Goof around with children.
  • Do something silly.
  • Make time for fun activities (e.g. bowling, miniature golfing, karaoke).
Shared laughter is one of the most effective tools for keeping relationships fresh and exciting. All emotional sharing builds strong and lasting relationship bonds, but sharing laughter and play also adds joy, vitality, and resilience. And humor is a powerful and effective way to heal resentments, disagreements, and hurts. Laughter unites people during difficult times.
Incorporating more humor and play into your daily interactions can improve the quality of your love relationships— as well as your connections with co-workers, family members, and friends. Using humor and laughter in relationships allows you to:
  • Be more spontaneous. Humor gets you out of your head and away from your troubles.
  • Let go of defensiveness. Laughter helps you forget judgments, criticisms, and doubts.
  • Release inhibitions. Your fear of holding back and holding on are set aside.
  • Express your true feelings. Deeply felt emotions are allowed to rise to the surface.

Bringing more humor and laughter into your life

Want more laughter in your life? Get a pet…

Therapeutic Benefits of Pets
Most of us have experienced the joy of playing with a furry friend, and pets are a rewarding way to bring more laughter and joy into your life. But did you know that having a pet is good for your mental and physical health? Studies show that pets can protect you depression, stress, and even heart disease.
Laughter is your birthright, a natural part of life that is innate and inborn. Infants begin smiling during the first weeks of life and laugh out loud within months of being born. Even if you did not grow up in a household where laughter was a common sound, you can learn to laugh at any stage of life.
Begin by setting aside special times to seek out humor and laughter, as you might with working out, and build from there. Eventually, you’ll want to incorporate humor and laughter into the fabric of your life, finding it naturally in everything you do.
Here are some ways to start:
  • Smile. Smiling is the beginning of laughter. Like laughter, it’s contagious. Pioneers in “laugh therapy,” find it’s possible to laugh without even experiencing a funny event. The same holds for smiling. When you look at someone or see something even mildly pleasing, practice smiling.
  • Count your blessings. Literally make a list. The simple act of considering the good things in your life will distance you from negative thoughts that are a barrier to humor and laughter. When you’re in a state of sadness, you have further to travel to get to humor and laughter.
  • When you hear laughter, move toward it. Sometimes humor and laughter are private, a shared joke among a small group, but usually not. More often, people are very happy to share something funny because it gives them an opportunity to laugh again and feed off the humor you find in it. When you hear laughter, seek it out and ask, “What’s funny?”
  • Spend time with fun, playful people. These are people who laugh easily–both at themselves and at life’s absurdities–and who routinely find the humor in everyday events. Their playful point of view and laughter are contagious.
  • Bring humor into conversations. Ask people, “What’s the funniest thing that happened to you today? This week? In your life?”

Developing your sense of humor: Take yourself less seriously

One essential characteristic that helps us laugh is not taking ourselves too seriously. We’ve all known the classic tight-jawed sourpuss who takes everything with deathly seriousness and never laughs at anything. No fun there!
Some events are clearly sad and not occasions for laughter. But most events in life don’t carry an overwhelming sense of either sadness or delight. They fall into the gray zone of ordinary life–giving you the choice to laugh or not.

Ways to help yourself see the lighter side of life:

  • Laugh at yourself. Share your embarrassing moments. The best way to take yourself less seriously is to talk about times when you took yourself too seriously.
  • Attempt to laugh at situations rather than bemoan them. Look for the humor in a bad situation, and uncover the irony and absurdity of life. This will help improve your mood and the mood of those around you.
  • Surround yourself with reminders to lighten up. Keep a toy on your desk or in your car. Put up a funny poster in your office. Choose a computer screensaver that makes you laugh. Frame photos of you and your family or friends having fun.
  • Keep things in perspective. Many things in life are beyond your control—particularly the behavior of other people. While you might think taking the weight of the world on your shoulders is admirable, in the long run it’s unrealistic, unproductive, unhealthy, and even egotistical.
  • Deal with your stress. Stress is a major impediment to humor and laughter.
  • Pay attention to children and emulate them. They are the experts on playing, taking life lightly, and laughing.

Checklist for lightening up

When you find yourself taken over by what seems to be a horrible problem, ask these questions:
  • Is it really worth getting upset over?
  • Is it worth upsetting others?
  • Is it that important?
  • Is it that bad?
  • Is the situation irreparable?
  • Is it really your problem?



Using humor and play to overcome challenges and enhance your life

The ability to laugh, play, and have fun with others not only makes life more enjoyable but also helps you solve problems, connect with others, and be more creative. People who incorporate humor and play into their daily lives find that it renews them and all of their relationships.
Life brings challenges that can either get the best of you or become playthings for your imagination. When you “become the problem” and take yourself too seriously, it can be hard to think outside the box and find new solutions. But when you play with the problem, you can often transform it into an opportunity for creative learning.
Playing with problems seems to come naturally to children. When they are confused or afraid, they make their problems into a game, giving them a sense of control and an opportunity to experiment with new solutions. Interacting with others in playful ways helps you retain this creative ability.
