- Drink plenty of water and avoid alcohol and sleeping pills.
- Headache with nausea, dizziness or exhaustion means stop going up. If it does not improve with rest, go down.
- Breathlessness while resting, a wet cough, confusion or trouble walking straight is an emergency: go down at once, by night if necessary, and get medical help.

- Medicines such as acetazolamide (Diamox) are for a doctor to prescribe; they are not a substitute for going up slowly.
