The disadvantages of not drinking too much coffee

1. Confusing caffeine in times of stress 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.

two。 Aggravate high blood pressure 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.

3. Induced 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. For women, it may increase the threat of osteoporosis. 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.
