10 Fun Facts About Sleep

There's no denying that sleep is essential for good health and well-being. Unfortunately, our ever-increasing load of responsibilities -- from work and kids to cooking and laundry -- leaves us little time for shuteye. On the whole, though, people enjoy sleeping and feel more energized after getting a sufficient amount of it.

Here are a few fun facts about sleep from the National Sleep Foundation:

Exercising regularly makes it easier to fall asleep and contributes to sounder sleep. However, exercising sporadically or right before going to bed will make falling asleep more challenging.
Man is the only mammal that willingly delays sleep
Divorced, widowed and separated people report more insomnia
Newborns sleep a total of 14 to 17 hours a day on an irregular schedule with periods of one to three hours spent awake
Most healthy adults need seven to nine hours of sleep per night. However, some individuals are capable of functioning without drowsiness or sleepiness after as little as six hours of sleep. Others can’t perform at their peak unless they’ve slept ten hours.
We naturally feel tired at two different times of the day: about 2:00 AM and 2:00 PM. It is this natural drop in alertness that is chiefly responsible for the post-lunch dip.
Snoring is the main cause of sleep disruption for approximately 90 million American adults (37 million on a regular basis)
Scientists still don't know if animals dream during REM sleep, as human beings do
One of the primary causes of excessive sleepiness among Americans is self-imposed sleep deprivation
People who don’t get enough sleep are more likely to have bigger appetites due to the fact that their leptin levels (leptin is an appetite-regulating hormone) drop, promoting appetite increase

No response from someone IS a response

Make no mistake about it: When you don't get a response from someone -- whether they fail to answer your texts or return your phone calls -- it is still a response, and a powerful one at that. When a person fails to respond, it's a direct reflection of their interest -- or lack thereof -- in the relationship. Few things are more aggravating than having to hound a partner, friend, or relative for some sort of reply after we've reached out to them. Yes, we get busy from time to time, but that doesn't give anyone the right to leave the other person hanging. A terse text with something like "Been busy, will reach out soon" doesn't say much, but at least it shows some effort to bring the other person up to speed on why they've fallen off the radar. Failing to provide a response for weeks -- if not months -- communicates that you are just not a priority, and that you'll have to wait your turn to get this individual's attention. This is n...

Do you have Isolophilia? Find out...

You're probably asking yourself, "What in the world does Isolophilia mean?" It sounds like it would be something negative, doesn't it? After all, words that end in "philia" (e.g., pedophilia) tend to involve things we want nothing to do with. But Isolophilia isn't something all people deplore. In fact, introverts like me welcome it. Put simply, Isolophilia is defined as having a strong affinity for solitude. It describes a person who relishes being alone. While extroverts can only take so much solitude, we introverts find that it rejuvenates us. In order to recharge our batteries, we need to retreat to a quiet environment where we we're left alone to rest and/or gather our thoughts. Extroverts, on the other hand, become bored and drained when they're alone for a lengthy period of time. Social interaction is the fuel that drives them. So while an extrovert would probably do anything to avoid feelings of Isolophilia in most cases, an...

This will spell the end of your relationship

When asked to think about the most common culprits for a relationship's going south, most people will point to cheating, complacency, and taking one's partner for granted. While these are all valid -- and documented in various posts on this blog -- there are certain habits on the part of partners that may not kill the relationship right away, but cause it to erode more gradually. Among the most egregious of these is expecting your significant other to be perfect. They pick at your follies any chance they get. Nothing you do is ever good enough. In fact, you will never measure up to an ex, neighbor, or accomplished co-worker. Perhaps this all sounds a bit familiar. When you feel as though you're constantly being put under the microscope, it can inflict lasting damage on the relationship and your self-esteem. You're walking on eggshells all the time, praying you don't say or do something that's going to trigger your partner. This is no way to live, let alone ca...
