In this episode, Mario and Max discuss the scientific evidence on alcohol consumption. They debunk common myths and explain how alcohol affects the body, from the first sip to its long-term effects on the brain, sleep, and cellular health. The episode explores why even small amounts of alcohol are harmful and why the trend toward more mindful and reduced alcohol consumption, particularly among younger people, is a positive development.
Mario and Max note that alcohol consumption is declining, particularly among younger people. They attribute this to greater health awareness, the availability of alternatives such as mocktails and alcohol-free beer, and changes in leisure activities. Despite this positive trend, average per capita consumption in Germany remains high at 10.6 liters of pure alcohol per year, suggesting high consumption among older generations.
Alcohol is both water- and fat-soluble, allowing it to enter every cell in the body freely. In the body, it is broken down into acetaldehyde, a highly toxic, carcinogenic substance that causes DNA damage. Acetaldehyde contributes to an increased risk of at least seven different types of cancer, including colorectal, liver, and esophageal cancer. The rate at which acetaldehyde is broken down is genetically determined and cannot be accelerated.
Alcohol works by enhancing the effects of the inhibitory neurotransmitter GABA and suppressing those of the excitatory neurotransmitter glutamate. In the short term, this leads to relaxation and reduced inhibitions. With regular consumption, however, the brain adapts, creating an imbalance when you are sober: less GABA and more glutamate. The result is a higher baseline level of stress, anxiety, and nervousness—a state known as "hangxiety." Alcohol thus briefly relieves the stress that it causes over the long term.
Many people use alcohol as a sleep aid. However, it acts as a sedative, leading to a rapid loss of consciousness rather than restorative sleep. Alcohol severely disrupts sleep architecture by reducing the important deep sleep and REM sleep stages. REM sleep is essential for psychological processing and recovery. Without it, you feel more stressed, less focused, and more emotionally unbalanced the next day.
The myth that a daily glass of red wine is healthy—the "French Paradox"—persisted for a long time. Mario and Max explain that the studies showing this effect had methodological weaknesses. Their non-drinker groups included many people with a history of alcohol dependence who already had health problems. Once this factor is accounted for, a linear dose-response relationship emerges: every drop of alcohol increases the risk of disease.
Even one alcoholic drink can disrupt sleep, increase next-day stress and cause cellular damage. We explain why there is no risk-free level of alcohol consumption—and why drinking can still feel relaxing at first.
Breathe through your nose instead of your mouth? Mario and Max explain how nasal breathing more than doubles the release of nitric oxide, thereby noticeably increasing oxygen saturation in the body. They also explore how nasal strips, mouth taping, and nasal rinses can help with blocked airways.
Take a warm shower in the evening to cool down and fall asleep faster? Mario and Max explain the physiological process behind vasodilation and how a controlled drop in core body temperature can improve sleep efficiency. They also reveal why timing is crucial—and why just ten minutes in the sauna can be enough.
Acute stress cannot be switched off through willpower alone—but it can be regulated through breathing. Mario and Max explain the neurobiological effects of the physiological sigh, also known as cyclic sighing. They show how a double inhale reopens collapsed alveoli and how a slow exhale activates the vagus nerve.
