This product, called OXYfit, is claimed to improve your concentration when driving – by giving you a shot of oxygen. The maker says a blast of its propellant-free oxygen helps drivers combat fatigue, relieve stress and improve concentration. The motorist simply inhales and after about eight to 10 breaths, OXYfit says the benefits start to kick in. Researchers at the Albert-Ludwig University in Freiburg, Germany, say this is more beneficial than a cup of coffee in helping drivers to perk up.
