Today’s Health= Many people listen to music with earphones while exercising. This is because it can relieve boredom and increase the effectiveness of exercise. Listening to music while exercising can actually improve exercise ability, but you should be careful because the habit of listening with earphones can harm your ear health.
Let’s start by looking at the effects of music on exercise. Music has a positive effect on the amygdala of the brain, which is involved in emotional processing, and the cerebellum, which controls physical reflexes and emotions, helping you forget about fatigue and increase your concentration on exercise. There are also research results showing that even when you exercise while tired, listening to music improves your exercise ability.
According to a study conducted at the University of Edinburgh in Scotland, the research team conducted cognitive tests on people who usually enjoy running, made them mentally tired, and then listened to music while exercising. As a result, it was found that exercising while listening to music had a beneficial effect on exercise ability similar to when the subjects were not mentally tired.
However, if you exercise while wearing earphones, you can get otitis externa. The external auditory canal, which is the passage from the ear to the eardrum, is a part of the skin that is vulnerable to bacterial infection. Infection occurs more easily as humidity and temperature increase. When you exercise, your body temperature rises and you sweat, making you hot and humid. Sweat also forms in your ears. At this time, if you wear earphones and block your ear canal, ventilation is poor, and the temperature and humidity in your ears increase.
When otitis externa occurs, the ear feels itchy and stuffy as if it is blocked, and it hurts. It hurts when yawning, chewing food, or pulling the earlobe. If the symptoms get worse, there may be an odor coming from the ear or hearing may be poor. If the ear canal is injured by touching the inside of the ear with a cotton swab or fingernail because it is itchy, there is a risk of secondary infection.
If you listen to music with earphones while exercising, you may develop noise-induced hearing loss. In a study published in the international academic journal PLoS ONE, 17.2% of 2,879 middle and high school students reported that their noise-induced hearing loss was caused by earphone use. Noise-induced hearing loss is a condition in which auditory cells are damaged due to continuous exposure to noise, and it is difficult to completely cure.
To listen to music while exercising and protect your ears, it is best to use open-type earphones or bone conduction headphones that allow as much air to pass through the ear canal as possible. If you must wear earphones, you should minimize the time you wear them. It is also important to keep your ears and earphones clean. If you sweat where your earphones meet, you should quickly take them out and dry them thoroughly. The volume should be set to less than 50% of the maximum, and after putting the earphones in your ears, you should take them out for at least 10 minutes and let your ears rest.
