In this solosode, you'll explore how to make peace with tinnitus after acoustic trauma, including the half dozen different root causes that can drive it and the specific supplements and technologies with research behind them, why cardiovascular fitness itself seems to protect your hearing as you age, and whether tattoos are actually as risky as people think, from the heavy metals hiding in colored ink to what a major 2024 study found about tattoos and lymphoma risk.
I also break down a new study showing you can get the same heat shock protein boost from heavy resistance training that you would normally only get from a sauna, why stacking a hard workout with a sauna session afterward may give you the best of both worlds, and take a closer look at a study making headlines for supposedly debunking the whole eating before bedtime rule, because the fine print tells a very different story than the headline does.

Mindsip insights from this episode:
Leverage heavy resistance training to boost heat shock proteins
Heavy resistance training, such as six sets of ten back squats, can significantly increase heat shock proteins, a benefit often associated with sauna use.
Reevaluate eating before bed based on timing insights
A recent study debunking the myth of not eating before bed was misleading, as it compared eating 2.5 hours versus 4.5 hours before sleep, while problems typically arise within 90 minutes of bedtime.
Stimulate vagus nerve to relieve tinnitus symptoms
Vagus nerve stimulation, using devices like Hulis or Truvaga, can provide remarkable and acute relief for tinnitus symptoms.
Assess tattoo risks for lymphoma due to ink pigments
A 2024 study found that tattooed individuals had a 21% higher adjusted risk of lymphoma, likely due to industrial pigments in inks migrating to lymph nodes.
Stimulate muscle growth with 1.5 grams of leucine-enriched amino acids
Just 1.5 grams of leucine-enriched essential amino acids can stimulate muscle protein synthesis as effectively as 40 grams of whey protein.
Choose tocotrienols over standard vitamin E for better absorption
Standard vitamin E (alpha-tocopherol) is just one fraction of the vitamin E family and can block the absorption of the more beneficial tocotrienols.
Increase essential amino acid intake to prevent muscle loss on GLP-1s
Being in a caloric deficit from GLP-1 medications can require a threefold increase in essential amino acid intake to prevent muscle loss.
Increase protein intake to 40 grams per meal after 40
Due to anabolic resistance, an older adult may need around 40 grams of protein per meal to get the same muscle-building response a younger person gets from 20 grams.
Address jaw issues to alleviate tinnitus
Musculoskeletal issues in the jaw, head, and neck, such as TMJ dysfunction, are a frequently overlooked cause of tinnitus.
