handling stress

One of our sprints my developer deployed code very late time
and I didn't have much time to get job done. But I was working
so hard worked extra hours and especially nights and I was
finished my task on time.
My first approach is trying to calm down and work extra hours.
I try to react to situations, rather than to stress. That way, the
situation is handled and doesn't become stressful. Mostly
these have helped me to handle stress. I also eat chocolate.
Also, in scrum environment we working as a team. I always
maintain good communication and relationship with my
colleagues. So, they trust me and they can communicate with
me very easily. I always avoid miscommunication and my team
believe me every time.
Sometimes some requirements are not understandable, so I try to
figure out and I try to understand the requirements. In the
beginning of the application I spend extra effort to understand
functionality. Sometimes it takes time to understand.
