Can I prevent or slow down early-stage hearing loss?
Noise-induced hearing loss is largely preventable by limiting exposure to sounds above 85 dB(A) and wearing hearing protection. Once the damage is permanent, there is no going back.
Prevention is literally the only effective strategy here. Once permanent damage to your hearing has occurred, it cannot be undone by any treatment or supplement.
Damage occurs with repeated exposure to sounds of 85 dB(A) or more for eight hours a day. Below 75 dB(A) there is probably no lasting risk. A busy nightclub, a rock concert, or music at high volume through earbuds can easily reach 100 dB(A) or more. As a result, young people are increasingly experiencing hearing loss at an early age.
There is, however, an early stage that is still reversible: auditory fatigue. Do sounds seem muffled after a concert, or do you have a ringing in your ears? If so, your hair cells are overloaded. If you rest in time, your hearing can partially recover. If you keep up the exposure without sufficient recovery periods, the damage becomes permanent step by step.
The best protection in the workplace is tackling the noise source itself, through noise dampeners or acoustic shielding. Earplugs or earmuffs help, but are only truly effective as a supplement to these measures. The same applies outside work: earplugs at a concert only work if you wear them consistently and they fit properly.
In practical terms: keep music through earbuds below 60 percent of maximum volume, limit listening time, wear hearing protection in noisy environments, and consciously plan recovery time after exposure to loud sounds. Research into medications or antioxidants that prevent damage to the hair cells of the inner ear is ongoing, but has not yet produced anything proven to work in humans.
Seven controlled claims, based on five to six studies from epidemiological, audiological and guideline-based research. The damage threshold of 85 dB(A) and the irreversibility of permanent damage are causally and strongly substantiated. The evidence for social noise, auditory fatigue and prevention programmes is moderate. For education and pharmacological protection, the evidence is limited and associative.
How do I keep my eyes healthy and prevent cataracts or macular degeneration?
Protect your eyes with UV-filtering glasses, a diet rich in vegetables and fruit, good diabetes management and regular eye check-ups. If cataracts have advanced significantly, surgery is the only proven solution.
How do I keep my joints supple and prevent osteoarthritis?
Exercise and maintaining a healthy weight are the best-supported ways to prevent osteoarthritis and manage symptoms; however, no treatment stops the disease once it has begun.
What helps with osteoarthritis (joint wear)?
Exercise, losing weight where applicable in the case of excess weight, and an anti-inflammatory gel on the knee have the strongest supporting evidence; always discuss oral pain medication with your doctor because of the side effects.
How do you recognise gum recession early, and which habits can inadvertently make the problem worse?
Early gum recession is usually only detected by the dentist, not at home. Aggressive brushing, inflammation and smoking are the habits that offer the most concrete room for improvement.
Does having a pet benefit your health and longevity?
A pet can contribute to more physical activity, less loneliness, and a better sense of wellbeing, but whether it also extends your lifespan has not yet been demonstrated. If you are considering a pet primarily for your health, a dog is the best-supported choice, but weigh the practical burdens as well.
What actually helps with chronic low back pain?
Strength and stabilisation exercises have the strongest evidence base for chronic low back pain; if the effect is insufficient, anti-inflammatory drugs are the first pharmacological step, but opioids and surgery can almost always be avoided.
