Taiwanese doctor reveals research results: When is the best time to drink coffee? How many cups can you drink in a day?
Dr. Wang Jianli cited research that found drinking coffee in the morning (4 a.m. to 11:59 a.m.) may be more effective at reducing the risk of heart disease and all-cause mortality than drinking coffee throughout the แทงบอล UFABET ราคาดีที่สุด ไม่มีขั้นต่ำ day.
The relationship between time and amount of coffee consumption
Dr. Wang Jianli, chief physician of the Department of Internal Medicine at National Taiwan University Hospital, said that previous studies focused on “coffee intake“, such as how many cups per day, and its effect on the risk of heart disease, diabetes, or death. It was found that drinking 2-3 cups of coffee per day was associated with a reduced risk of heart disease and death. However, there has been no deep analysis of the “time of drinking coffee” and its effect on health.
Major research from Tulane University
The new study used data from the National Health and Nutrition Examination Survey (NHANES), which included more than 40,725 adults aged 18 and older, and examined coffee drinking timing across three time periods:
- Morning : 04:00 – 11:59
- Afternoon : 12:00 – 16:59
- Evening and Night : 17:00 – 03:59
Interesting results
- People who drank coffee in the morning had a significantly reduced risk of death from all causes and heart disease compared to those who did not drink coffee.
- For those who drank coffee throughout the day or at other times, there was no clear association with reduced risk.
- Even if you drink more than 3 cups of coffee in the morning, your risk of death and heart disease is still reduced, but if you drink coffee throughout the day or in the evening, the protective effect is not as clear.
Why Drinking Coffee in the Morning Is Good For You
- Biological cycles and sleep
Drinking coffee in the afternoon or evening can disrupt sleep and the body’s biological cycles, reducing the benefits that coffee can provide. However, drinking it in the morning is in line with the body’s natural cycles. - Anti-inflammatory and metabolism properties:
Coffee contains anti-inflammatory compounds such as polyphenols, which can help reduce inflammation that often occurs in the morning. - Lifestyle
People who drink coffee in the morning tend to have health-promoting behaviors, such as waking up early, exercising, and getting quality sleep.
Tips for drinking coffee for health
Dr. Wang Jianli suggests that if you are someone who drinks 1-3 cups of coffee a day, you should drink it in the morning until noon to avoid affecting sleep. If you have to drink it in the afternoon or evening, be careful about the amount and the effect on sleep, especially if you already have insomnia.
However, this research is an observational study and cannot clearly confirm a cause-and-effect relationship. However, it is a recommendation for those who want to benefit from coffee for health.
