Question

what happens in the body when a person is sleep - deprived on a regular basis? view available hint(s)
○ inflammation is reduced.
○ overall immune function is impaired.
○ metabolic rate is increased, and weight loss may occur.
○ muscle strength and function are enhanced.

Explanation:

• For "Inflammation is reduced": Sleep deprivation is known to increase inflammation, not reduce it, so this is incorrect.
• For "Overall immune function is impaired": Regular sleep deprivation disrupts the immune system's normal functioning, impairing its ability to fight infections and perform other immune-related tasks. This is consistent with scientific knowledge about sleep and immunity.
• For "Metabolic rate is increased, and weight loss may occur": Sleep deprivation is associated with a decreased metabolic rate and often weight gain (due to hormonal changes like increased ghrelin and decreased leptin), so this is incorrect.
• For "Muscle strength and function are enhanced": Sleep is crucial for muscle recovery and growth; deprivation would hinder, not enhance, muscle strength and function, so this is incorrect.

Answer:

B. Overall immune function is impaired.
