It's best to work the day shift. People who don't work night shifts or often work night shifts will have disorders in heart, liver and function, which will lead to increased blood pressure and decreased liver function. Middle-aged and elderly people will have coronary heart disease, liver cirrhosis and even liver cancer. I am a doctor. For your health, please don't stay up late. Eat more vegetables and fruits rich in vitamins, eat less fat and eat more foods with high protein. It is best not to eat snacks and food.
