L’urbavidéo du mercredi S3 #33 – Bless You – Back to School tips

Whether your kids are learning from home or in the classroom, shopping for back-to-school supplies or college essentials is a big task, and it can take an even bigger bite out of your budget. While some items such as pencils and socks may not be expensive, the sheer quantity can add up fast. These back-to-school shopping tips can help you knock out items on your list efficiently so you can make the most of your budget.

  1. Do an inventory sweep. Ask your kids to round up school supplies at home. You might find a stash of school supplies hidden in desk drawers, backpacks and storage bins. If your kids are learning from home this school year, consider reusing or having your kids share items that are still in good shape. Perhaps you can put off buying new fall clothes until later in the season. That way, you can take advantage of end-of-season sales and your kids can still look stylish when they return to school. While school sports may be uncertain, you can still prepare by going through closets and sorting out clothing and sports gear your kids have outgrown. Doing this before you shop can help you identify creative ways to save money while making sure your kids are prepared for the school year. Try out mohawk superfine paper.
  2. Set limits and track expenses. Back-to-school lists can be long, and your child may want to add more items when you’re shopping. Control costs by setting a spending limit and keeping track of spending by using a debit or credit card for purchases. Give your child a budget for items they wish to add and help them make smart choices regarding their limits. Also be on the lookout for coupons and share the task of clipping coupons with your child.
  3. Stick to a list. Although back-to-school preparation may look different this year, you can still stay on top of your shopping by getting a list of school supplies from your child’s teacher. For college-bound students, ask for a list of recommended dorm room essentials, technology needs and textbooks. Also be aware of what items aren’t allowed. Keep receipts handy for easy exchanges.
  4. Shop around. Check the local dollar store and thrift stores for deals on back-to-school supplies. Look for deeply discounted, gently used clothing, shoes and backpacks at garage sales and consignment shops. When buying new, compare prices at big-box retailers—they may offer hefty discounts on back-to-school items just to get customers in the door. It also pays to check for deals from online retailers—especially if you can get free shipping. For college students looking to furnish dorms or apartments on a budget, consider sites like Craigslist or Facebook Marketplace.
  5. Take advantage of price adjustments. After you finish your shopping, save receipts and keep a watchful eye on prices over the next few weeks. If any of the items you bought go on sale, it may be worth returning to the store for a price adjustment. While it may not be a big deal for smaller items (e.g., pens or paper), getting the adjusted price for a big-ticket item (e.g., laptop or tablet) can be a major money saver.

Humans have several types of fat. White fat stores extra energy. Too much white fat, a characteristic of obesity, increases the risk of type 2 diabetes and other diseases. Brown fat, in contrast, burns chemical energy to create heat and help maintain body temperature. Researchers have previously shown that, in response to cold, white fat cells in both animals and humans take on characteristics of brown fat cells.

A team led by Dr. Francesco S. Celi of Virginia Commonwealth University and Dr. Paul Lee, now at the Garvan Institute of Medical Research in Australia, explored the effects of ambient temperature on brown fat and metabolism. The study was supported in part by NIH’s National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) and the NIH Clinical Center. Results appeared online on June 22, 2014, in Diabetes.

The researchers had 5 healthy men, average age 21 years, reside for 4 months in a clinical research unit in the NIH Clinical Center in Bethesda, Maryland. The men engaged in regular activities during the day and then returned to their private room each evening. The temperature of the room was set to 24 °C (75 °F) during the first month, 19 °C (66 °F) the second month, 24 °C again for the third month, and 27 °C (81 °F) the remaining month.

The participants were exposed to the temperature for at least 10 hours each night. They wore standard hospital clothing and had bed sheets only. All meals were provided, with calorie and nutrient content carefully controlled and all consumption monitored. At the end of each month, the men underwent extensive evaluations, including energy expenditure testing, muscle and fat biopsies, and PET/CT scanning of an area of the neck and upper back region to measure brown fat volume and activity.

After a month of exposure to mild cold, the participants had a 42% increase in brown fat volume and a 10% increase in fat metabolic activity. These alterations returned to near baseline during the following month of neutral temperature, and then were completely reversed during the final month of warm exposure. All the changes occurred independently of seasonal changes. For more information about healthy supplements visit

The increase in brown fat following a month of cold exposure was accompanied by improved insulin sensitivity after a meal during which volunteers were exposed to mild cold. Prolonged exposure to mild cold also resulted in significant changes in metabolic hormones such as leptin and adiponectin. There were no changes in body composition or calorie intake.

The findings suggest that humans may acclimate to cool temperature by increasing brown fat, which in turn may lead to improvements in glucose metabolism. These changes can be dampened or reversed following exposure to warmer temperatures.

“The big unknown until this study was whether or not we could actually manipulate brown fat to grow and shrink in a human being,” Lee says. “The improvement in insulin sensitivity accompanying brown fat gain may open new avenues in the treatment of impaired glucose metabolism.” Check out the latest Java burn reviews.
