Explain how things such as circadian rhythms jet lag shift work and sleep disorders may effect alertness and attention span?

Answer 1

The circadian rhythm are the natural cycles of our sleep. It is measured in a 24 hour intervolve. Humans are creatures of habit and once your body sets itself on a rhythm you will feel the effects once broken. For example if you go to bed at nine every night, wake at seven the next morning, go to work at 8:30 and get off at 5:30. One night you decide to stay out with your friends until midnight and go to sleep an hour later you have broken your cycle. That's why you will feel tired the next day. Jet lag and different work shifts do this too. Your sleep pattern is unpredictable and varies in quantity and quality. This lowers your effectiveness and your attention as you are not getting a consistent quality and quantity pattern of rest.

Answer 2

Circadian rhythms are the body's internal clock that regulates alertness and attention throughout the day, with peak alertness during the day and decreased alertness at night. Jet lag disrupts this rhythm, causing fatigue and reduced attention span. Shift work can also disrupt circadian rhythms, leading to decreased alertness and attention due to working during times the body is naturally programmed to rest. Sleep disorders like insomnia or sleep apnea can result in poor sleep quality, leading to decreased alertness and attention span during waking hours.
