¿Por qué te despiertas cansado y tus hormonas no funcionan bien? - Dr. Alexander Krouham - 447

Sleep is not a light switch that you flip at bedtime. According to Dr. Alexander Krouham, the quality of your sleep is determined the moment you wake up in the morning. In this episode of El Podcast de Marco Antonio Regil, Dr. Krouham explains that poor sleep is rarely an isolated problem—it is a symptom of a deeper breakdown in how your body produces energy, processes hormones, and manages stress. The conversation weaves together mitochondrial biology, hormonal balance, gut health, and social connection into a practical framework for reclaiming restorative sleep.

The Morning Sabotage: Coffee, Cortisol, and Adenosina

The most common mistake people make is reaching for coffee immediately upon waking. Dr. Krouham explains that caffeine and adenosine—the molecule of fatigue—are chemically similar. Adenosine accumulates throughout the day and binds to receptors in the brain, gradually signaling that it is time to sleep. When you drink coffee first thing in the morning, the caffeine occupies those same receptors, blocking the signal. But this does not give you energy; it merely blinds your brain to how tired you actually are. Meanwhile, adenosine continues to build up. When the caffeine wears off hours later, all that accumulated adenosine floods the receptors at once, causing the infamous afternoon crash that drives cravings for sugar or a nap.
