Dr. Anshuman Kaushal, a specialist in advanced laparoscopic gastrointestinal and bariatric surgery, argues that coffee should not be the first beverage consumed in the morning. He emphasizes that upon waking, the body activates a natural cortisol response, which helps with alertness and blood pressure. Consuming coffee right away can lead to negative effects such as acidity, anxiety, and irritability. Instead, he recommends starting the day with 300-500 ml of plain water to rehydrate the body after sleep. Following hydration, he suggests exposure to sunlight and light physical activity before having coffee about an hour after waking. Kaushal also notes that the ideal caffeine limit is around 400 mg, though individual factors like genetics and sleep quality can influence this. He warns against consuming coffee late in the day, as it can disrupt sleep, particularly for those with anxiety or sleep disorders. This advice serves as a guideline for a healthier morning routine, promoting better hydration and overall well-being.
