Heat-retaining materials are substances that have the ability to trap and hold heat for an extended period of time. These materials are often used in insulation to prevent heat loss in buildings or to keep objects warm. Common examples of heat-retaining materials include wool, fiberglass, and certain types of foam. By using these materials, energy consumption for heating can be reduced, making them environmentally friendly options. **

Slight pressure on both eyes, a pressure sensation in the upper head area, and slight dizziness can be caused by a variety of factors.
