Bad habbites [habits].
Sadly I have a bad habit which is staying awake at night and sleeping all morning.
When I wake up after this such a long time of sleeping I feel dizzy and have a bit of a headache, because in a normal life cycle said that we should sleep at least 5 hours at night (after midnight).
So the unhealthy thing which that happens to us is of our own making.
So My first advice to everyone and myself at first is "Stop doing it!" (:
