How else can we say “warmth”?

Heat is another word for physical warmth
1. the state of a body perceived as having or generating a relatively high degree of warmth.
2. the condition or quality of being hot: the heat of an oven.
3. the degree of hotness; temperature: moderate heat.
4. the sensation of warmth or hotness: unpleasant heat.
5. a bodily temperature higher than normal: the heat of a fever; the feeling of heat caused by physical exertion.
Warmth can be experienced through mental and physical heat. Due to intense, pleasant emotions we can experience mental warmth. This warmth can increase happy feelings and create a sense of safety and belonging. Generally, mental and internal warmth can be experienced through the feelings created by another living being.
Physical, or external warmth, can be created and stimulated by such things as; the sun, a fire, light bulbs, blankets, etc. These things can help  us feel safe and comfortable in our environment. Being cold and not warm will create a feeling of anxiety and uncomfortable experiences for the living being the cold is affecting. Since birth, all living beings crave and need warmth. The feeling of physical warmth is a need that all humans must fulfill. Physical warmth (safety/shelter) is one of the levels of the Maslow’s Hierarchy of Needs that all humans must accomplish in order to live a happy, successful life. From birth we need the soft, warm touch of another human being to comfort us. This need falls under the category of belongingness and social interaction on Maslow’s chart. A baby’s cerebellum does not develop properly if they are not rocked and cradled but another loving, warm human being. The need for social and physical warmth can be connected back to the mental warmth because both are needed in order to survive and thrive in a social environment.
