First of all, it is a healthy and sound sleep, in a completely dark room, without any devices, in a strictly allotted time for this. I go to bed at nine to ten in the evening and get up at five to six in the morning. This is the first and most important condition for a normal, enjoyable life. Without this discipline, all your efforts to improve your quality of life will be futile. The second is physical activity - the minimum of any healthy person is 10,000-200,000 steps in the fresh air, in any weather, every day, as well as swimming, cardio loads. The third is a full-fledged diet rich in vitamins and minerals, as well as a sufficient amount of good, high-quality water. All this is very familiar and you have already heard about it, but there are no other secrets.
