Extreme variety. The peaks are bitterly cold even in summer. Some lower slopes are tropical. The south side of the range (near India) is very wet in summer, and dry in winter. The north side (near Tibet) is always dry, and always cold at night.
Unfortunately, there is no secret to always having naturally warm hands in cold weather. Keeping your hands covered with gloves or mittens, staying active to promote circulation, and staying hydrated can help maintain warmth.
No necessarily. There are cold deserts where the temperature remains quite mild or even cold in the summer.
Antarctica is polar. Both polar climates are 'cold' in 'summer' with temperatures usually below freezing.
Even though the name is cold, it is caused by a virus that can be caught even during the warmer times of year.
Denmark is always cool even in the summer!
Mars is very cold even in summer.
There are hot deserts and there are cold deserts so it is not always hot in a desert. The Antarctic Desert stays below the freezing mark even in summer. Some deserts are hot during the day but get quite chilly at night.
Near the North Pole and on top of mountains. Even in the summer, the region near the North Pole in Canada and Alaska, and on the tallest mountains, it still is somewhat cold in the summer.
Not necessarily. Some people have a slight problem with their circulation, or they are very sensitive to changes in temperature, and their hands feel cold even on a warm day. This condition is inconvenient but it doesn't have to mean something is wrong. However, sometimes, cold hands can be a symptom of a medical condition like diabetes or anemia. There are also some people who have a condition called "Reynaud's Syndrome," in which the hands (and sometimes the feet) are frequently cold. (Reynaud's is in the family of autoimmune diseases.) You may want to see your doctor and get tested to determine if these conditions are what is causing your hands to be cold all the time.
