Hot or Cold Temperature
All the outer layers of the body are susceptible to the outward state of the atmosphere, whether it is cold or hot. The body naturally responds to the environment’s state and condition. When the sun is high, and the temperature is too hot, the skin tends to dry and wither when not hydrated with enough water or any fluids. Most of the time, the shoulders, hands, arms, and face are the areas that easily get sunburned as the sun’s heat is directly positioned on them throughout the day. These body parts crack, dry out, lose their fair complexion, and get chapped.
On the other hand, when the temperature is too cold (particularly in winter), the external organs get numb and react through shivering or teeth clattering. When the lips (especially the lower lip) are exposed to much heat, the weather is arid, or there is a sudden temperature drop, it swells badly. Though the swelling sometimes happens overnight, it usually subsides during the day using a cold compress (ice wrapped in cloth/pack), a moisturizing lip balm, an ointment, or a home-prepared remedy.
