Why one always feels cold, even during hottest days?

Hello all.

My mother-in-law is being treated for hypothyroidism. She's 5'6" and weights only 127lbs. She eats normally, but nothing "cathces on".

Even though she drinks lots of coffee, eats salty foods, etc, her blood pressure is always pretty low (around 90/60). Even on the hottest summer days she is feeling cold and she tends to step out to be exposed to the sun for 10-15 minutes to start feeling warm again. If I did that, I think I'd faint and drop down, as that happens on extremely hot days.

Also, when she goes to the beach, she is comfortable with almost falling asleep on the sun (she could be lying there for hours), while others tend to run to the shade after 10-15 mins of sunbathing. Does anyone have idea what could be her problem, why is she always cold?

Thanks.

hypothyroidism Causes people to always feel cold. She should see her medical doctor and possibly get an adjustment or different medication. Dehydration can also cause some of the cold that she's feeling. Have her drink purified water with mineral water mixed 50/50. Source(s): retired doctor of Naturopathic medicine

i too have the same condition although not to that extreme.I have been taking meds for about 4-5 yrs and only recently have noticed the some of the symptoms diminishing.i have felt better though since i started them.and istill am cold-natured to some extent.your mom-in-law should talk to her doctor about this.and i hope she is using a sun block when she goes to the beach
I'm low thyroid as well. My hands & feet are always cold to touch. It probably poor circulation of the blood.
Sounds to me like poor circulation and possible clogged arteries. She should be checked out by a cardiologist for heart problems. It's better to catch it before she actually has a heart attack or a stroke. The doctors can go in and clean out her arteries with out leaving any permanent damage if it is caught in time
