Hii, from last 4 days I used to study at night from 9 pm to 4 am approx after that I prefer some breakfast type and sleeps upto 12 noon and after taking lunch took rest upto 4 pm. I following this schedule becoz I am not able to concentrate at day time. I also used to exercise at evening and meditates. So I want to ask that will it effect my health in any way. Please suggest me I am a student and if it will effect then how I can maintain it also I doesn't feel any frustration while studying pls suggest me if there is any chance of getting unhealthy.
