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.
Cold showers in the morning for better focus and fat burning? Mario and Max debunk myths about brown adipose tissue, explain how cold actually affects the nervous system, show how box breathing helps during ice baths, and explain why people who take cold showers get sick less often.
Collagen is marketed for skin, joints, tendons and connective tissue, but how strong is the evidence? We review benefits, limitations, risks and the differences between hydrolyzed collagen peptides, gelatin and vegan products.
