Those who have been exposed to sudden, excessive noises can reduce the risk of developing a hearing loss by taking the antioxidant acetylcysteine. This antioxidant can for example be found in our food.
Swedish researchers have found that antioxidants can prevent against hearing loss if one has been exposed to noise exposure.
In the search for methods to protect one's hearing after noise exposure, Swedish researchers found that the antioxidant acetylcysteine has a protective effect on noise-related hearing loss. Acetylcysteine, usually used as an expectorant, should be taken as soon as possible and at the latest four hours after an acoustic accident, recommends Ulf Rosenhall, professor at the Karolinska University Hospital in Stockholm, Sweden.
Antioxidant in the medicine cabinet
In the study, the researchers examined a group of Swedish officers in a shooting exercise in which they were exposed to excessive noise. By using a sensitive technique that can measure even minor hearing loss, they examined the officers hearing before and after the exercise. The study showed that acetylcysteine protected the officers hearing when it was taken within one hour after exposure to the noise.
The Swedish military have now implemented a directive which states that the antioxidant should now be found as standard in military medicine cabinets.
However, antioxidants also exist in our food, especially in fruits and vegetables. The vitamins C, A and E are some of the most important antioxidants. Therefore, Professor Ulf Rosenhall believes that nutrition is also vitally important in the fight against developing hearing problems.
