More energy on less sleep!


Shut-eye is the ultimate energizer, if you can get enough of it. For the 99.9 percent of us who can't; we have five instant uppers.

1. Skip the venti latte
You might be tempted to suck down the biggest coffee ever when you’re tired, but if you need lasting energy, sip a little at a time throughout your day. Harvard research found that small, frequent doses of caffeine helped people stay awake for 28 hours.

2. Sniff something lemony
Splurge on that citrus hand cream: A new study found that whiffs of lemon made women feel peppier. “The scent increases production of norepinephrine, a hormone associated with energy,” says lead study author Janice Kiecolt-Glaser, Ph.D.

3. Eat some good carbs
The fiber in whole grains like brown rice and whole-wheat bread provides a long-lasting source of energy for your brain and muscles, says metabolism researcher William Evans, Ph.D. Simple carbs like sweets will give you a quick rush but leave you tired later.

4. Spend five minutes with some funny online videos
It might not seem terribly productive, but laughing at a guy flying off a speeding treadmill will perk you up temporarily. Research shows that a hearty chuckle revs up the respiratory system, oxygenating the body and making you feel awake.

5. Get moving
A low-intensity workout like a short bike ride can boost energy levels by 20 percent, researchers at the University of Georgia in Athens found. Regular exercise also improves sleep—so when you do hit the sack, you sleep more soundly and wake more rested.

Why Disasters Are Getting Worse?

By: AMANDA RIPLEY Thu Sep 4, 12:40 PM ET In the space of two weeks, Hurricane Gustav has caused an estimated $3 billion in losses in the U.S. and killed about 110 people in the U.S. and the Caribbean, catastrophic floods in northern India have left a million people homeless, and a 6.2-magnitude earthquake has rocked China's southwest, smashing over 400,000 homes. If it seems like disasters are getting more common, it's because they are. But some disasters do seem to be affecting us worse - and not for the reasons you may think. Floods and storms have led to most of the excess damage. The number of flood and storm disasters has gone up by 7.4% every year in recent decades, according to the Centre for Research on the Epidemiology of Disasters. (Between 2000 and 2007, the growth was even faster - with an average annual rate of increase of 8.4%.) Of the total 197 million people affected by disasters in 2007, 164 million were affected by floods. It is tempting to look at the line-u...

Best scents to help you relax and stay alert

By: Allie Firestone, 10/15/08 3:03 PM Fall is chock-full of scents, and that’s one of the reasons I love it. Picking up on the huge variety of smells—whether it’s pumpkin pie, freshly-baked cookies, or spiced apple cider—is something I recently realized that I take for granted. Scientists say that humans can distinguish over 10,000 different odor molecules. Turns out, while it doesn’t require any conscious thought, our ability to pick up on a scent involves a sensitive and complex function that has powerful effects on our memory and behavior. How else can I explain how one whiff of pumpkin immediately conjures up thoughts of trick-or-treating and holiday gatherings? Scientists dedicated to tracking the complex relationship between smells, our behavior, and our moods have found that certain scents trigger feelings, including those that help us relax and fall asleep and those that perk us up and keep us alert and focused. Sleep and Relaxation Looks like I’m not the only one tossing and t...

Banks Boost Customer Fees to Record Highs

by Jane J. Kim Thursday, November 13, 2008provided by: theworldstreetjournal.com Bounced Checks, Overdrafts and ATM Use All Cost More; Penalizing Repeat Offenders Banks are responding to the troubled economy by jacking up fees on their checking accounts to record amounts. Last week, Citigroup Inc.'s Citibank started charging some customers a new $10 "overdraft protection transfer fee" to transfer money from a savings account or line of credit to cover a checking-account shortfall. Citibank had already raised foreign-exchange transaction fees on its debit cards and added minimum opening deposit requirements for its checking accounts. Over the past year, J.P. Morgan Chase & Co.'s Chase, Bank of America Corp., and Wells Fargo & Co. have boosted the fees they charge noncustomers who use their automated teller machines to as much as $3 per transaction. With all these changes, the average costs of checking-account fees, including ATM surcharges, bounced-check fees a...
