Isn't strange the the glaring Sun as well as
the icy cold snow can both leave us dehydrated?
In the case of the Sun we will be aware of the dehydration
but no one will associate it with the snow and ice!

Dear Mrs. Visalakshi Ramani,

I had the same doubts in my mind.
Later when I read articles on this subject, I came to know this condition is called Acute Mountain Sickness (AMS) or Altitude Sickness and it occurs when you travel in high attitudes above 10,000ft.

A few lines to help others who go on trekking pilgrimages in The Himalayas.

Acute mountain sickness is due to a combination of reduced air pressure and lower oxygen levels at high altitudes.The causes of altitude sickness are not fully understood. When we move away from MSL up into higher altitudes air pressure gets lowered. Air at lower pressure has less oxygen per lungful. At lower air pressure, water evaporates faster. This can lead to dehydration. Dehydration due to the higher rate of water vapour lost from the lungs at higher altitudes may contribute to the symptoms of altitude sickness. Easy way to prevent altitude sickness is to give the body enough time to get used to the rarefied air. A slow and steady ascent is help a lot. Adequate hydration is a must. The body is constantly losing fluid from the lungs and the skin in the high, dry environment. Drink enough to maintain a clear and abundant urine output. Other measures include eating a high carbohydrate diet, climbing high during the day and coming lower down to sleep, and to mild to moderate activity during the day rather than just lying around are suggested to keep the body fit.

Brahmanyan,
