Even on multiday adventures, you'll still want your pack close to 20 percent of your body weight, so you'll need to be extra thoughtful about the gear and clothing you're carrying to compensate for all that extra gear.
By putting a heavy weight on your shoulders in the wrong way, the weight's force can pull you backward. So people who carry heavy backpacks sometimes lean forward. Because of the heavy weight and this unnatural position, they can develop shoulder, neck, and back pain.
Don't Waste SpacePacking is best done modularly. Try to pack in kits based on need. By keeping items of similar purpose together, you'll save time and energy while trying to find things later. Colored stuff sacks and compression bags are great ways to organize and save space.
Always put heavier or larger items at the bottom of the suitcase. This will make it easier to find items and will keep heavy objects from crushing or damaging lighter pieces such as souvenirs and toiletries. Pack lighter items like dress shirts on top.
Pain caused from excessive loads has gained the term “backpack syndrome.” Backpack syndrome causes headaches, neck and back pain, and fatigue. There have been studies examining the effects of carrying backpacks on one shoulder versus both shoulders. Carrying a bag on one shoulder causes significant asymmetries.
It can cause poor posture, compressed discs in the spine, and even curvature of the spine. Straps digging into the muscles of the shoulder were also found not just to irritate the area, but to cause potential damage to the nerves of the hands and arms. These issues aren't just small problems.
Overloaded backpacks may strain muscles and joints, cause neck pain, and can lead to headaches. Heavy backpacks can also pinch or strain nerves at points of contact.
In terms of kilos, a full 55 litre backpack will weigh around 14kgs approximately whereas a full 70 litre backpack will weigh around 20kg. That's too much to travel around the world with. Naturally, as a backpacker, you want to travel as light as possible so I would recommend taking a 55litre.
But, based on my own experience, 70L is too large for a carry-on item with most airlines. If you're looking for the optimal balance between the largest bag possible, and the most airlines it would be allowed on, I find that 35L (53x35x20-cm) is allowed on 155 of the 175 airlines I could find data for.
Wearing a backpack that is too heavy can cause back pain, neck pain, numbness and tingling in the arms and hands, and weakness in the arms and hands. Done repetitively or for long periods of time, this practice can potentially damage the spine and sensitive nerves of the neck and back.
Using a heavy bag actually causes children to have back problems, such as spinal misalignments, because it pulls bones, ligaments, and muscles downward. The misalignments can cause pain, fatigue, and other side effects. They can cause long-term pain and side effects if not addressed properly.
You're going to set down on the floors or other places that's going to be dirty. You may throw it in the trunk of your car. White gets dirty quicker than any other color!! I would purchase a color that doesn't get dirty so easily.
