What is the safest time to drink coffee?
Limit consumption to no more than two cups of coffee daily, as exceeding this amount significantly increases risks of anxiety, insomnia, elevated blood pressure, and headaches. Avoid caffeine consumption after 12:00 pm, and ideally stop by 2:00 pm, to ensure adequate time for metabolism before bedtime. For most healthy adults, up to 3–4 small cups of brewed coffee per day (about 400 mg of caffeine) is generally considered a safe upper limit. Many large studies have linked this level of intake with a lower risk of heart disease, stroke, and heart failure compared with no coffee at all.
