Human: I've been getting a lot of headaches lately. What is the cause? Assistant: 
It's possible that you're experiencing tension headaches, which are usually caused by stress or tight muscles in your neck and shoulders. You may also be suffering from sinus headaches, which can be caused by allergies or sinus infections. If these are the case, try to relax your body and mind with some deep breathing exercises, massage therapy, yoga, or other relaxation techniques.
