Think about this for a second, how many people do you ever see wiping down the handles and grips of exercises machines they use?
Yes, most well educated gym goers will clean the surfaces of benches and seats that they come in to contact with, but most of us simply don't think to wipe down the surfaces that we actually take hold of with our hands and this could be one of the biggest factors responsible for passing around many types of germs and bacteria from person to person. Wearing gym gloves could help combat this by forming a barrier between your hands and the things that you and other folks take hold of.
Whilst it is true that sweat itself from other people poses no threat to you at all, the bacteria and germs that it carries however most certainly can do. These germs are the ones responsible for all manner of illness such as stomach upsets, colds or viruses etc.
The main thing to watch out for is that you don't touch your mouth, eyes or nose with your hands. Now this is far easier said than done and most of time you'll probably do this without even thinking about it. To be safe totally safe, you'd need to wash your hands after every set or exercise that you did... something that is obviously not practical to do.
However there is a far more obvious solution. By wearing gym gloves, you can ensure that no sweat get's in to contact with the skin on your hands. The gloves will be the part touching any sweat left on weights by others and not your skin.
Did you know on average we lose at least 1 litre of sweat every day and this is increased enormously if you work out in the gym for any amount of time. You don't need to worry about your own sweat as it is an odorless cooling agent which helps to regulate your body's temperature. In fact studies carried out in Germany recently show that some of the protein found in sweat may actually kill off one strain of bacteria. However other studies carried out by scientists in Demark pointed to a conclusion that sweat is the perfect breeding ground for superbugs.
Either way, it is better to be on the safe side and protect yourself and the skin on your hands and just wear the gym gloves in the first place. They can help to improve the control you have over the weights you use, may support your wrists and fingers and above all protect the skin on your hands meaning you're far less likely to suffer from blisters and calluses.
