Brief Answer:
Lab tests... good diet... multivitamins

Detailed Answer:

Hi,

Please specify that have you checked your body temperature when you feel very cold.
And do you have any medical problem as anaemia or low thyroid level or low blood pressure or low pulse or low sugar level?
Are you taking any drug?

If everything is ok then no problem.

I have seen many elderly persons who feel excessively cold especially at night.

There is no specific reason for this. You are using extra clothing and its good idea. Take a good multivitamin antioxidant combination containing ginseng. Such products are available as over the counter products. Maintain a nutritious diet.

Hope I have answered your query.

Regards,
Dr. Varinder Joshi, General & Family Physician
