'False Facts' about Sleep
Most people found it difficult to sleep and most of us aren’t getting enough sleep. Hence people search for the tips and tricks to get a sound and peaceful sleep. Everyone seems to have the tricks for it. But how do you sort through that noise and find the methods that work for you?
Here are the definitive answers to the biggest myths about sleep:
get Cialis Professional Everyone must get 8 hours of sleep.
FACT: Some of us do best with eight hours of sleep; others do better with seven, nine, or even four hours. It’s all influenced by factors including genetics, age, and activity level.
For example, there are several genes connected to being a “short sleeper,” someone who can function on just a few hours of sleep.
Alcohol helps you sleep.
FACT: Although it might make you feel drowsy, that nightcap might actually disrupt your sleep. A small Australian study found that people who drank alcohol before bed tended to have certain patterns in their brain consistent with disrupted sleep. So even if they were experiencing restorative sleep, those waves negated any positive effect.
Scientists have been studying the counterintuitive relationship between the drowsiness that comes from drinking alcohol and actual sleep since the 1930s. There’s some evidence to suggest it has to do with the body metabolizing alcohol at the same time it’s trying to sleep, suggesting that it’s difficult for the body to multitask.
You can catch up on sleep.
FACT: Yes, the idea of being able to sleep in until noon on the weekends sounds enticing. But it’s wreaking havoc on your internal body clock. Every time you shift your hours, it feels roughly like flying from New York to California and then back again in one weekend, leaving your body confused on Monday.
Try to get a consistent amount of sleep each night at roughly the same time.
Sleep deprivation won’t mess up other aspects of your health.
FACT: While you may not feel it after one night of poor sleep, sleep deprivation can contribute to some pretty serious health conditions when it’s chronic and consistent.
Sleep deprivation has been linked to an increased risk of diseases such as diabetes, obesity, coronary heart disease, and stroke. But even in the short term, you may notice some negative consequences, such as poor vision, mood swings, and headaches.
Drinking warm milk can help you sleep.
FACT: Milk contains tryptophan, a compound our bodies convert into the sleep-influencing brain chemical serotonin. But there’s not enough of it in milk — 10 times too little, actually — to help you fall asleep.
Naps are bad for you.
FACT: It’s complicated. Nap too much during the day, and you risk not being able to fall asleep at night. But, in short 10-20-minute stints, researchers have continually found them to be effective ways to help people feel more alert during the day. Plus, naps have been linked to better memory, mental performance, and even boosted immune systems.
You can only dream during REM sleep.
FACT: Contrary to popular belief, you can actually dream during all phases of sleep.
The two primary stages are REM (Rapid Eye Movement) and non-REM. Though you dream during both stages, your dreams during non-REM are different, according to experts.
Your dreams during non-REM are usually related to daily events whereas REM dreams tend to be the more fantastical type.
generic Valtrex online Counting sheep helps you fall asleep.
FACT: If you regularly have trouble sleeping, this method might actually make you take longer to fall asleep. A 41-personstudy of people with insomnia found that on the nights they were instructed to count sheep, it took longer for them to fall asleep than on nights with no instructions.
Looking for other pre-sleep thoughts? Try picturing relaxing images. When those same participants did this, they fell asleep quicker than with no instructions or with instructions to count sheep.
If you die in your dreams, then you die in real life. buy Baclofen
FACT: Don’t worry, you won’t. This myth follows close behind the misconception that you could kill a sleep walker by waking them.
While you won’t die from your dreams, scientists still struggle to understand why we need so much sleep in the first place. After all, lying unconscious for hours on end could have made our ancient ancestors vulnerable to predators.
People who are under anesthesia are asleep.
FACT: Just because you’re unconscious doesn’t mean you’re asleep. When we snooze, our brains produce certain types of brain waves.
When we’re under an anesthetic, however, the brain hardly emits any brain waves at all, which clearly distinguishes it from regular sleep. In fact, anesthesia is more like a “reversible drug-induced coma” than a good night’s slumber.
Insomnia means that you have trouble falling asleep.
FACT: Insomnia is one of many sleep disorders, but it doesn’t necessarily mean that you have trouble getting to sleep.
About 1 in 3 Americans suffers from at least some form of mild insomnia, which could mean they experience any of the following:
Waking up to early and not being able to fall back asleep
Waking frequently during the night
Waking without feeling refreshed
Trouble falling asleep
The elderly need less sleep.
FACT: The elderly tend to sleep for a shorter time at night and wake up earlier in the morning, but that doesn’t necessarily mean they need less sleep overall.
Older people tend to wake up more throughout the night, meaning they tend to be less well-rested compared with if they’d stayed asleep, Sudhansu Chokroverty, who specializes in neurophysiology and sleep medicine at the JFK Medical Center, told WebMD.
“This is why they take naps during the day,” Chokroverty said.
