Which practice may weaken our circulatory system?

a. Having a daily exercise

b. Staying up late at night

c. Taking vitamins every day

d. Avoiding vices like smoking​

b. Staying up late at night.

Staying up late at night,  practice may weaken our circulatory system.

Staying up very late disrupts the body's natural sleep-wake cycle, which can affect a person's mental functioning and energy levels the next day. Frequently staying up all night may lead to sleep problems and can have long-term effects on health.
