Altitude
Lachung & Yumthang Valley reaches 4,700 m, high enough for altitude sickness to be a real risk whatever your age or fitness.
- Gain height gradually. Above 3,000 m, try not to sleep more than about 500 m higher than the night before, and take a rest day for every 1,000 m gained.
- 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.
- Speak to a doctor before the trip if you have heart, lung or blood-pressure problems, or are travelling with small children.
- Medicines such as acetazolamide (Diamox) are for a doctor to prescribe; they are not a substitute for going up slowly.
