Physical trauma (ie; being punched, kicked, etc), a tension headache, or, worst case scenario, a stroke. Be aware in any changes to your muscle control. Seek medical attention immediately if that happens.
the blood is not flowing to all parts of the body especially the head.
Several types of headache disorders can cause this to happen. Cluster headache causes fairly short lived, very severe headaches that can occur several times a day for a period of time. See your physician or headache specialist for appropriate diagnosis and treatment of Migraine and headache disorders.
more than likely the positioning of your neck and your jaw tightening from lack of support.
Pain is a protective function. When injured, pain reminds a person not to move the injured part. When ill, pain (such as a severe headache) reminds a person to lie down.
Gravity.
If you want to stop a headache that seems worse than normal, take liquid medicine. Next, get into a room with no sunlight. (Sunlight bothers my headaches!) But before you lay down, make sure the room is silent and steady. Get a cold wet washrag or a icey fresh glass of water. Lay down, try to sleep, keep the rag on your forehead, drink your water, and that should solve it within 30 min. Try it! At least it always works on me! ^^
Gravity. Things naturally travel in a straight line unless another force acts on them. The moon would travel in a straight line but is dragged down by the gravity of the earth. This constant acceleration towards the earth causes it to orbit the earth in a curve.
An airplane or bird wing has a curved upper part and a straight lower part. The lower part, when moving against air, causes more pressure down than the upper part, which causes flight.
Swmmer here. Usually this happens all the time when you are just getting used to the water pressure in the pool because you never really experenced anything like it out of the water
they get a headache from hanging upside down
