(1) what is the role of sleeping and eating?
SLEEP: Sleeping’s two main roles are conservation and restoration. When you sleep, your bodie conserves energy and soldifies the attainment of new tasks, so it is also important for memory. It is believed that sleeping aids in the consolidation of learning and memory. Also, when you sleep your body repairs itself and wasteful toxins in your body are removed, your blood is cleaned as your body restores itself.
FOOD: eating’s main purpose is to provide the body with energy. This energy is used for brain functioning, cellular repair and growth. It’s also very interesting to note that the brain uses 80% of your bodies energy. So people who go on bad diets where they dont eat, they might think they’re getting thinner, but they should think of what their depriving their poor brain of! this is why a lot of nutritionists suggest eating frequently, in smaller portions, every few hours.
(2) does lack of sleep or bad eating habits affect mental abilities?
SLEEP: lack of sleep is known as sleep deprivation. sleep deprivation may be linked to more serious diseases, such as heart disease and mental illnesses, such as psychosis and bipolar disorder. Studies show that REM sleep is essential for blocking neurotransmitters and allowing the neurotransmitter receptors to "rest" and regain sensitivity which in turn leads to improved regulation of mood and increased learning ability. Sleep deprivation also increases stress hormones, which may reduce new cell production in adult brains in conjunction with decreased levels of concentration, moodiness, slower response rates and impaired cognitive functioning.
FOOD: food is vital for energy and growth. however bad eating habits such as eating in frequently would simply result in lower energy levels and inability to concentrate, and also learning, retaining and recalling information would be harder.
(3) how do sleep and diet affect growth and development?
well, i answered some of it in the above questions, but sleep allows your body to conserve energy from food which is then used for growth, but more specificially cellular growth and repair, i.e when you cut yourself your cells undergo mitosis to duplicate cells and heal the wound. certain foods like calcium promote bone and teeth growth while other foods like caffiene and nicotine stunt growth. sleep promotes cognitive development and mental development and aids in the retention of information, transferring it from short term memory to long term memory.
(4) what are the negativies of lack of sleep and food? nature vs. nuture.
i don’t really have more to add from (2), but the nature versus nurture debates concern the relative importance of an individual’s innate qualities (nature0 versus personal experiences (nuture) in determining or causing individual differences in physical and behavioral traits.
anyway, hoped that helped, pick up any first year psych textbook and you’ll have all the information you can absorb, and if you sleep afterwards, you might remember it
