It is not suitable to drink coffee before going to bed at night. Drinking a lot of coffee before going to bed can easily lead to insomnia and inability to sleep.

Precautions:

People with calcium deficiency should avoid drinking coffee. Studies by foreign researchers show that drinking two cups of coffee drinks will lose about 15 mg of calcium in the body, so people who drink this drink often should eat more foods rich in calcium, such as meat, bean products, shrimp skin, kelp, laver and fungus.

People with hyperlipidemia should avoid drinking coffee. Men who regularly drink caffeine drinks have much higher blood cholesterol than men who don't drink, especially the increase of low-density lipoprotein related to atherosclerosis, which can promote atherosclerosis. Women who drink coffee regularly have slightly higher blood cholesterol than normal people.
