[38] Influence of Stress and Sleep on Thermogenesis

Question 1

How does stress influence thermogenesis?

Answer 1

Stress, particularly chronic stress, can increase thermogenesis as part of the body’s “fight or flight” response, which increases metabolic rate and heat production.

Question 2

What is the effect of sleep on thermogenesis?

Answer 2

Sleep generally reduces the metabolic rate and thus decreases thermogenesis as energy demand decreases during rest. However, REM sleep is associated with increased thermogenesis compared to other sleep stages.

Question 3

Why does chronic stress increase thermogenesis?

Answer 3

Chronic stress leads to a prolonged “fight or flight” response, which involves increased metabolic activity and subsequently increased thermogenesis.

Question 4

How does REM sleep differ from other sleep stages in terms of thermogenesis?

Answer 4

REM sleep is associated with increased thermogenesis due to increased brain activity and possibly other factors, compared to other sleep stages.

Question 5

What’s the potential impact of sleep deprivation on thermogenesis?

Answer 5

Sleep deprivation can disrupt the balance of energy metabolism, potentially leading to increased thermogenesis during wakeful periods to compensate for the energy deficit.
