Let's just say this is your first blood donation. I haven't eaten much or slept since (you're not insomnia, are you? Or are people too tired to sleep? At present, you feel the same as usual, which means that your body is still healthy and can withstand such tossing. You are lucky not to faint on the side of the road (I have fainted before).
There is no problem now, but no matter whether you insist on donating blood every six months in the future (oh, I personally do, I don't ask you to do so), as long as you live a life that can't guarantee normal diet and sleep quality, your body will collapse sooner or later! I'm not alarmist! )
In addition, collapse is a chronic recessive development. You may feel that you seldom catch a cold, but you may be very ill after a sudden fever.
Donating blood is an act worthy of encouragement. Do one good deed every day.
But instant noodles are not nutritious things, they can only be used occasionally to satisfy hunger, and they can never be eaten for a long time.
Rice and eggs are cheap and nutritious. When you can't afford meat, at least make sure you can eat eggs.
As for vegetables, I have had a hard time, and I have also picked leaves in the market, so that I can eat vegetables even if I have no money.
Health is capital.
A good diet and rest can ensure your health, and you can go all out to do what you want.
Difficulties can be overcome!
Come on!
