PATTAYA, Thailand – For many people, coffee is more than just a drink. It is part of their morning routine and a daily source of energy. But the question remains: is coffee helping the body or quietly causing harm? Medical experts say coffee can provide both benefits and risks depending on the amount consumed, added ingredients and the timing of each cup. When consumed properly, coffee contains compounds that may support overall health. Coffee beans are rich in antioxidants, especially polyphenols, which help protect cells from damage, reduce inflammation and may support healthy ageing.
For those looking for the healthiest option, black coffee such as an Americano or drip coffee is considered a better choice than sweetened coffee drinks. Adding large amounts of sugar, cream or artificial creamers can reduce the health benefits and increase unnecessary calories. Coffee timing can also affect how the body responds. Caffeine stimulates the central nervous system, helping people feel more alert and increasing energy expenditure. Some studies suggest caffeine may support exercise performance by helping the body use stored energy more efficiently.
For people who exercise, drinking coffee around 30 to 45 minutes before a workout may allow caffeine levels to peak during physical activity, potentially helping improve endurance and reduce feelings of fatigue.
However, drinking coffee too late in the day may interfere with sleep. Caffeine has a half-life of around five to six hours, meaning a significant amount can remain in the body hours after consumption. A cup of coffee in the afternoon may still affect the brain’s sleep signals, making it harder for some people to fall asleep or achieve deep rest. Many health professionals recommend avoiding coffee after around 2 p.m. if sleep quality is a concern. Experts also advise against drinking coffee immediately after waking. The body naturally produces cortisol, a hormone linked to alertness, at higher levels in the morning. Waiting one to two hours after waking before having coffee may help some people get a stronger effect from caffeine. A suggested time for the first cup is between around 9:30 a.m. and 11:30 a.m., when natural alertness may begin to decline.
For healthy adults, the generally recommended maximum caffeine intake is about 400 milligrams per day, which is roughly equivalent to three to four standard cups of coffee. For many people, one to two cups daily may provide benefits while keeping caffeine intake moderate.
Choosing unsweetened black coffee, drinking it at the right time and avoiding excessive consumption may allow coffee lovers to enjoy their favorite drink while supporting energy, focus and long-term health.
