Medical and nutrition experts have provided guidance regarding the consumption of coffee and its impact on physiological health. Cardiologist Aurelio Rojas suggests limiting intake to five cups per day and consuming coffee before 3:00 PM to prevent sleep disruption. While some concerns exist regarding digestive health, physiology professor Kim Barrett notes that the stomach’s mucus layer typically protects against coffee-related irritation.

Further advice regarding morning routines suggests that caffeine consumption immediately upon waking may stimulate cortisol and potentially disrupt hormonal balance or blood sugar regulation. Experts recommend prioritizing rehydration with electrolytes and natural light exposure over immediate caffeine or digital stimulation to better regulate circadian rhythms.
