What are the advantages and disadvantages of drinking coffee in the morning?
Coffee time
Drinking coffee is best after breakfast and lunch, because it can promote gastrointestinal peristalsis, help digestion, can break down high-calorie, high-fat foods, and will not cause irritation to the stomach like drinking coffee on an empty stomach. It's best not to drink coffee after dinner, for fear it will affect your sleep. If you want to stay up all night by drinking coffee, you may drink too much without knowing it, which is bad for your health.
Make a mess when you are nervous
Caffeine helps to improve alertness, agility, memory and concentration. But drinking more coffee than you are used to will produce the same dose of stimulants that you are used to, which can cause nervousness. For people with anxiety disorders, caffeine can worsen symptoms such as sweaty palms, palpitations and tinnitus.
Aggravate hypertension
Caffeine is often combined with other simple painkillers because of its analgesic effect, but if you take it in large quantities for a long time, if you already have high blood pressure, using a lot of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, coupled with emotional stress, it can have a dangerous multiplication effect, so people at risk of high blood pressure should especially avoid drinking caffeinated drinks during stressful times at work. Some people who drink coffee all the year round think they are immune to the effects of caffeine, but this is not the case. One study shows that blood pressure can rise for up to 12 hours after drinking a cup of coffee.
Induce osteoporosis
Caffeine itself has a good diuretic effect, if you drink a lot of coffee for a long time, it is easy to cause bone loss, which will adversely affect the preservation of bone mass and may increase the threat of osteoporosis for women. But the premise is that people who don't get enough calcium in normal food, or people who don't move very often, plus women after menopause, calcium loss caused by lack of estrogen, coupled with a large amount of caffeine, may pose a threat to bones. If you can enjoy it in a reasonable amount, you can still stop eating for fear of choking.
These people drink coffee carefully:
1. Patients with liver disease
Caffeine prolongs the time it takes to thank caffeine in the body. In general, the metabolism of caffeine in normal adults takes 2 hours, but in patients with liver disease or liver insufficiency, the metabolism of caffeine may take 4-5 hours, so patients with liver disease must be careful when drinking coffee, it is best not to drink it after dusk, so as not to affect sleep due to long metabolic time, and it is best not to exceed 1 cup a day.
2. Patients with digestive system diseases
I believe that people who often have stomachaches and stomach ailments have an experience, that is, doctors will tell them not to eat irritating foods, including wine, chili peppers, coffee, tea and carbonated drinks.
Coffee is among them because the tannic acid stimulates gastric acid secretion, which must be avoided if it is in the acute stage of digestive disease. After returning to health, if you drink coffee occasionally, it is best to use it after meals to avoid drinking coffee on an empty stomach.
3. Pregnant women
Many women pay special attention to all foods they eat since they are pregnant, and drinks containing caffeine are also taboo. This is mainly due to the slow metabolism of caffeine in pregnant women, the caffeine stays in the body for longer, and the fetus in the belly will not be able to remove caffeine from the blood through metabolism until eight or nine months.
4. Children
Due to the incomplete development of children's liver and kidney and poor detoxification ability, the half-life of caffeine metabolism will be prolonged, so generally speaking, children under the age of 12 need to ban caffeine intake. Even people in Europe and the United States who drink coffee as boiled water all day have very strict restrictions on children's drinking coffee.
