If you really can't avoid staying up late, you can only eat as many fruits and vegetables as possible and supplement more vitamins. The other is to add Lycium barbarum in the thermos cup to keep healthy as much as possible.
You can also assist some simple massage chairs and massage equipment to relax your shoulders, neck, waist and legs.
If possible, try to get enough sleep the next day.
So there is no healthy staying up late, only cherish your health and try to avoid staying up late, especially avoiding staying up late.
