Is it okay to drink coffee before bed?

Coffee is a very common drink in our daily life. When we are lacking energy or feeling tired, drinking a cup of coffee can help us to refresh ourselves. Because coffee has a certain stimulating effect, many people are very concerned about the timing of drinking coffee, especially worrying that drinking coffee at night will affect their sleep. So, is it good to drink coffee before bed? Let’s take a look below.

Drinking coffee at night is not good, it will affect your sleep. A recent study in the United States found that drinking coffee after 5 pm can easily lead to an hour less sleep at night because the stimulating effect of caffeine can last up to 6 hours.

During the four-day trial, participants took caffeine tablets six hours, three hours, and before turning off the lights to go to bed each day, and one of the doses was a placebo. In addition, one of the four days was filled with placebo, and three of the days were filled with placebo.

The results showed that drinking a large cup of strong coffee after 5 pm could lead to sleepless nights and drowsiness during the day. Even drinking two or three cups of coffee six hours before bedtime may reduce sleep time by an hour.

Many people know that drinking coffee before bed can make them excited and have difficulty falling asleep, but few people know that drinking coffee in the afternoon can also cause sleep disorders at night. The specific mechanism is that caffeine is the stimulating ingredient in beverages such as coffee and tea.

It interferes with the melatonin secretion by the pineal gland in the brain. Melatonin helps control the body's circadian rhythm, telling the body when to sleep and when to be awake. Disrupted melatonin levels can easily make it more difficult to fall asleep.
