Is the depth of blood color related to health?

Hello, human health needs absolute coordination and relative balance in order to maintain a relatively normal state. Because people are both flesh and blood and alive, they also contain many living things to form the body, so they will change at any time under the influence of climate, environment, work, mental health departments, diet and other factors. If a person uses different diets every day, it will directly lead to different blood colors, which will always directly affect blood color and body energy. The oxygen content in blood depends on the absolute value of energy. Clinically, it is not how many times you catch a cold a year, but that everyone will catch a cold, because the main factors of a cold are sudden climate change, seasonal changes, air conditioning and electric fans. If you don't pay attention or adjust at different times, you will catch a cold in the morning and evening. If you take precautions in every way, you are bound to catch a cold, that is, you are weak and have poor resistance.
