Let's ask our favourite friend:
Here are a few physiological and environmental factors that could be at play:
1.
Being near a volcano is exciting and possibly a bit stressful (in a good way). Novel or high-stimulus experiences like that can trigger
adrenaline and
dopamine release, which can temporarily override feelings of fatigue, nausea, or malaise—common hangover symptoms.
2.
If the volcano is at a higher elevation:
- The air may be cleaner and cooler.
- Slight hypoxia (lower oxygen levels) at altitude can cause increased breathing and circulation, which might help clear alcohol byproducts faster and wake you up.
3.
Natural sunlight helps regulate your
circadian rhythm and increases
serotonin and
vitamin D, all of which can help improve mood and energy. Sunlight may also suppress melatonin, helping you feel more alert.
4.
You probably had to
walk or hike to the volcano or around it. Light exercise:
- Boosts circulation and metabolism, helping process acetaldehyde (a hangover-causing toxin).
- Releases endorphins, improving mood and reducing pain.
5.
Some volcanic areas emit
sulfur dioxide and other minerals. While high levels of SO₂ can be irritating or toxic, very
low-level exposure in open air might have minor
stimulant effects or simply feel "invigorating" due to the distinctive smell and sensation—sort of like smelling salts.
6.
Being somewhere awe-inspiring and outside your normal environment is a
major distraction from your symptoms. Your brain may literally reprioritise where it allocates attention, making your hangover feel like it disappears.
TL;DR: The mix of adrenaline, movement, sunlight, cleaner air, and mental distraction likely combined to short-circuit your hangover. Nature therapy, volcanic edition.
