NCOA Thermoregulation Review Flashcards
This layer of the skin becomes thinner with age, reducing the body’s ability to retain heat.
What is the subcutaneous fat layer?
The subcutaneous fat layer provides insulation and helps in heat retention.
This change in sweat gland activity reduces the older adult’s ability to cool the body through perspiration.
What is decreased sweat gland function?
Decreased sweat gland function leads to less perspiration and reduced cooling.
This circulatory change reduces heat distribution to the extremities in older adults.
What is decreased peripheral vasodilation?
Decreased peripheral vasodilation limits blood flow to the skin and extremities.
The reduced ability to sense changes in temperature due to aging is primarily caused by this change in sensory perception.
What is decreased thermal sensitivity?
Decreased thermal sensitivity affects the body’s response to temperature changes.
This age-related decline in metabolism decreases the body’s ability to generate heat in cold environments.
What is reduced basal metabolic rate (BMR)?
A lower BMR results in less heat production.
Older adults taking this class of medications are at higher risk for hypothermia due to decreased metabolic heat production.
What are sedatives or CNS depressants?
These medications can impair thermoregulation.
This chronic condition, common in older adults, reduces circulation to the extremities, increasing the risk for cold-related injuries.
What is peripheral arterial disease (PAD)?
PAD can lead to poor blood flow and a higher risk of cold injuries.
An older adult with this endocrine disorder is at higher risk for hypothermia due to reduced thyroid hormone production.
What is hypothyroidism?
Hypothyroidism can lead to decreased metabolism and heat production.
Reduced hydration in older adults impairs this mechanism for cooling the body in hot environments.
What is sweating or evaporative cooling?
Sweating is essential for cooling the body during heat exposure.
This term describes the inability of older adults to recognize or respond appropriately to temperature extremes.
What is thermoregulatory impairment?
Thermoregulatory impairment can lead to serious health risks in extreme temperatures.
