Coffee relieves the pain? Caffeine because of its analgesic effect

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 large amounts of caffeine will only make your situation worse. Because caffeine alone can raise blood pressure, when combined with emotional stress, it can have a dangerous multiplier effect, so people at risk for high blood pressure should avoid caffeinated beverages especially when they are under high pressure at work. Studies have shown that drinking a cup of coffee can increase blood pressure for up to 12 hours.

Many people experience high spirits after drinking coffee and can't sleep. This is because there is a conductive substance called adenosine in the body, which can control nerve activity, causing breathing to slow down, mood to weaken, acid secretion to decrease, and diuretic effects. Caffeine, on the other hand, imitates adenosine, making the body think that the effects of adenosine have occurred, making you feel energetic, acid increased, more frequent urination, and naturally less able to sleep. It is worth noting that this brief wakefulness caused by caffeine does not mean that physical strength has really recovered. In addition, everyone's metabolic rate to caffeine varies, and their sensitivity to it varies, so some people don't feel that sleep is affected after drinking coffee. Therefore, a cup of hot coffee after getting up in the morning can lift the body and mind and make the mood more comfortable, while at night it may cause insomnia.

In recent years, as people pay more and more attention to the problems of calcium loss and osteoporosis, coffee has also generated considerable doubts. There is no direct evidence that caffeine causes osteoporosis, but some studies suggest that caffeine increases calcium loss.

Coffee lovers should eat more high-calcium foods to supplement calcium, such as preparing custard tablets or custard cakes with coffee, not only to supplement calcium, but also to make coffee more delicious.
