I regularly have subtle but uncomfortable headaches after a diving session, sometimes during the diving session as I progress. However, I had associated these with my tendency to dive with short surface intervals, little CO2 ventilating, and far from ideal rest during surface intervals. This tendency has occurred due to a number of factors:
- to prolong dive session by staying active.
- to have a higher dive frequency before session is aborted due to cold tolerance.
- to encourage surfacing early due to CO2 buildup.
- to avoid drifting in currents away from the desirable dive spot.

When I line dive I do not find myself getting these headaches, and I imagine in warmer conditions this would lessen for me as well.

However, that being said, I would love to hear any perspectives that may assist in alleviating these headaches.
