The human spine is made up of 33 bones called vertebrae, and between the vertebrae are discs that act as shock absorbers. When something heavy-such as a backpack filled with books-is incorrectly placed on your child's shoulders, the force of that extra weight can pull your child backwards. To compensate, your child may bend forward at the hips or arch his or her back, which can cause your child's spine to compress unnaturally. Because of the heavy weight he or she is carrying, your child might begin to develop shoulder, neck, and back pain.
Harnessing solar energy as a renewable power source has long been a feature in green living and solar backpacks is one of the offerings. Even the US military, which has adopted the use of renewable energy in its overseas missions in various ways, has equipped its troops in Afghanistan with solar backpacks. Of course it does make a lot of sense for them because solar backpacks are powered by sunlight.
First, it is important to note that backpacks can be grouped into four different categories - frameless (your typical backpack for college), external frame (hiking, camping), internal frame (hiking, skiing, sports), and the body pack (overnight camping, long trips). As I mentioned, the frameless style is your best bet for the college lifestyle. These backpacks are usually constructed using synthetic materials and are much cheaper than the other three types.
Frameless backpacks allow the wearer to carry a decent load without having to lug around a huge backpack. They are often constructed with many different pockets, and some are even designed to be waterproof. If you're looking for backpacks for college, definitely consider going frameless.
There are so many backpacks to choose from, and choosing the right one for your child is not always easy. Backpacks come in all sizes, colors, fabrics, and shapes-all of which help kids express their own sense of style. As practical as backpacks are for those who use them, backpacks can cause strained muscles and joints and back pain when worn incorrectly.
A backpack is probably the most versatile and use item that everyone owns. Everyone needs a backpack, no matter what the purpose may be. Backpacks are easy to carry around, they're useful because you can fit a lot of stuff into them, and most importantly, they are made of some pretty sturdy material so they can carry hold quite a bit of weight in them. Whether you call it a backpack rucksack, or a knapsack, there is no denying that a backpack is probably one of the most useful items you are going to have in your possession.
