1. The breathability and warmth of pantyhose are insufficient. If pantyhose are not warm enough, you may feel cold in your legs even if you wear them more. At the same time, if the pantyhose is airtight, sweat may stay on your skin and make you feel uncomfortable.
2. The external environment temperature is low. Even if you wear pantyhose, if the temperature of the outside environment is very low, it may make your legs feel cold.
3. Physical factors. If you are in poor health, such as weak constitution or poor blood circulation, your legs may feel cold.
To alleviate this situation, you can try to wear thicker and warmer socks, or wear a pair of warm pants under your socks. At the same time, you can also try to adjust your physical condition, such as strengthening exercise and improving blood circulation. If these methods still can't alleviate the problem, it is recommended to consult a doctor or professional.
