Skipping 1 night's sleep makes a person cranky and clumsy. After missing 2 nights of sleep, a person will have problems thinking and doing things; his or her brain and body can't do their normal tasks nearly as well. After 5 nights without sleep, a person will hallucinate (this means seeing things that aren't actually there). Eventually, it becomes impossible for the brain to give its directions to the rest of the body without sleep!
Sleep is as vital for survival as food, it gives your body a
rest and allows it to prepare for the next day…But chronic lack of sleep can
lead to health problems such as high blood pressure, obesity, depression, irregular
hormone production, a weakened immune system and memory lapses…
5 Signs You Need More Sleep:
- Cravings & Hunger: If you find yourself hungry all day (and not because you skipped breakfast or have recently amped up your gym routine) it might be because you've been skimping on sleep.
Research presented at the 2010 linked insomnia and lack of sleep with higher levels of the hormone Ghrelin, the same one that triggers hunger. This uptick in the hunger hormone seems to lead to not only increased snacking, but also a craving for high-carb, high-calorie foods, which may help explain why people who don't get enough sleep are at a greater risk of obesity. - You Are Emotional: Ever find yourself tearing up over an embarrassing TV commercial? While women might be quick to blame PMS, it could be a lack of sleep sending your emotions into overdrive. A 2007 study found that sleep-deprived brains were 60% more reactive to negative and disturbing images.
How Many Hours of Sleep Do You Really Need?
The average amount of sleep needed changes over our lifetime, especially during childhood and adolescence. Although there are averages, there will be individuals who fall both above and below these needs:- Infants (3-11 months) need 14-15 hours
- Toddlers (12-35 months) need 12-14 hours
- Preschoolers (3-6 years) need 11-13 hours
- School age (6-10 years) need 10-11 hours
- Adolescents (11-18 years) need 9.25 hours
- Adults need an average of 8 hours
- Elderly adults may need less than 8 hours
