If your hands get too warm with gloves on, take the gloves off!
My hands get sweaty too when shoveling snow. If you keep doing exercise, your hands might be quite comfortable with the gloves off. If they get too cold after a while, put the gloves back on.
This is no different from wearing a jacket. When you get hot from exercise, you take the jacket off, then put it back on when you cool down.
Please at least try this before using something disposable.
