Better sleep leads to a longer, healthier life

In this episode, Natalja Fischer and Dr. Felix Bertram reveal how four simple rhythms – time, light, metabolic and temperature – can significantly improve your sleep, and with it your health, performance and longevity. They start with the basics: why sleep matters so much in the first place. Sleep isn't passive rest – it's active recovery, essential for both body and mind. And it's not just about how long you sleep, but how well. Deep sleep, REM phases and the right cycle sequences are what drive true restoration – which is why seven to nine hours alone is no guarantee of waking up refreshed. The episode also covers when sleep problems become clinically relevant, and why alcohol and sleeping pills are more of a trap than a solution. Natalja and Felix wrap up with practical, actionable tips for improving your sleep – quickly and sustainably. Worth sticking with: After 6–12 months, the results stabilize – better sleep, longer life. Additional note: according to the German Lung Information Service, around 30 percent of men and 13 percent of women in Germany suffer from sleep apnea – a condition that is often underestimated, but highly treatable.
