Many people have started their day with a cup of coffee early in the morning, or as soon as they wake up. But studies have shown that drinking coffee early in the morning is not good for your health. Let's learn about the right time to drink coffee and the right amount to drink.
Why is the first morning coffee bad for your health?
Many people have the habit of drinking coffee as soon as they wake up in the morning. Or you can see many office workers starting their day with a cup of coffee on their way to work.
However, studies have shown that drinking coffee this early in the morning, especially too early, is not good for your health.
Impact on Cortisol Levels
When we wake up from sleep, our body increases the secretion of 'cortisol', one of the stress hormones. Cortisol levels are highest when we wake up in the morning. If you drink coffee in this situation, your cortisol levels will rise even higher, putting your body under stress.
The right time for the first morning coffee?
Dr. Gregory Marcus, a cardiologist at the University of California, San Francisco, advises that "the first coffee of the day should be between 9:30 am and 11 am." He says that the cortisol levels in our body drop the most between 9:30 am and 1 pm.
The last coffee time of the day is also important
Not only in the morning, but also the time you drink your last coffee of the day should be taken into account. According to Dr. Gregory, you should drink coffee at least 6 hours before going to bed. This is because drinking coffee too late can interfere with sleep due to the stimulating effect of caffeine.
Caffeine's Impact on Metabolism
The effect of caffeine on sleep varies depending on a person's caffeine metabolic rate. People with slow metabolism have a shorter sleep duration after drinking coffee, while those with fast metabolism are not significantly affected.
Recommended Caffeine Intake
The US FDA recommends limiting daily caffeine intake to 400mg for adults. That's about 3-4 cups of coffee. The French National Institute of Health and Medical Research recommends 100-150mg as the right amount for health benefits.
Coffee is the key to starting your day with energy. However, keep in mind that drinking coffee too early in the morning or right before bed is actually harmful to your health. Enjoy a wise coffee life by drinking the right amount of coffee at the right time.
