Question

question 8 (multiple choice worth 3 points) (a ler mc) which of the following statements is true? melatonin disrupts your bodys natural sleep cycles, particularly the important rem and deep sleep cycles. phones and tablets produce a neutral white light that can boost your bodys production of melatonin. the blue light emitted from tablets and phones halts the production of melatonin, which is needed for sleep. when your bodys natural sleep cycle is disrupted, there is little to no impact on your overall physical health.

Explanation:

Melatonin is a hormone that regulates sleep - wake cycles. Blue light from devices like tablets and phones inhibits its production. Melatonin actually helps regulate sleep cycles, not disrupt them. Also, phones and tablets do not produce light that boosts melatonin production, and disrupted sleep cycles have significant impacts on physical health.

Answer:

The blue light emitted from tablets and phones halts the production of melatonin, which is needed for sleep.
