Morning coffee can have harmful effects on the body, such as irritation of the digestive system.
Many people start their morning with coffee. This is to clear the mind, but ‘morning coffee’ is often harmful to the body, so be careful.
The hormone cortisol is the most secreted for 1-2 hours immediately after waking up. Cortisol is a hormone that acts as a natural stimulant, such as increasing bodily vitality. The problem is that the caffeine in coffee has a stimulant effect similar to cortisol. Caffeine intake when cortisol is secreted can lead to excessive arousal, which can lead to side effects such as headache, heart palpitations, and heartburn.
According to the Gachon University study, people who actually drank morning coffee were 2-3 times more likely to experience side effects than those who drank coffee during lunch and dinner time. Caffeine also affects the secretion of cortisol in the body.
Excessive secretion of cortisol increases the risk of high blood pressure, cardiovascular disease, and metabolic disease. The secretion of cortisol increases not only immediately after waking up, but also between 12:00 pm to 1:00 pm and 5:30 pm to 6:30 pm in the evening. Therefore, the best time to drink coffee during the day is 1 to 2 hours after waking up and from 1:30 to 5 pm.
Morning coffee can cause tooth discoloration. This is because many people do not brush their teeth until lunchtime after drinking coffee after going to work. Teeth have microscopic holes that go deep down. When you drink coffee, the brown pigment gets into the pores and stains the inner layer of your teeth.
If the coffee you drink is mixed coffee or coffee with syrup added, you should be concerned about not only discoloration but also tooth decay. A domestic study also found that people who drink coffee mix every day are 1.69 times more likely to have fewer than 19 teeth out of 28 compared to those who drink coffee once a month. Sugar, syrup, cream, etc. added to coffee increase acidity in the mouth, which increases acidity, which is the cause of tooth decay, and creates bacteria.
Digestive Tract Irritation
Drinking morning coffee on an empty stomach also adversely affects the digestive system. If you drink morning coffee on an empty stomach, various stimulants in coffee, such as caffeine and fatty acids, can attack the gastric mucosa and cause gastrointestinal diseases such as gastritis, gastric ulcer, and irritable bowel disease. In addition, a lot of stomach acid is secreted on an empty stomach, and the caffeine in coffee promotes gastric acid secretion more. Caffeine stimulates the lower esophageal sphincter, increasing the risk of stomach acid and food reflux. If these symptoms worsen, it can lead to reflux esophagitis.
