5 Everyday Things Keeping You From Good Sleep

5 อย่างที่จะทำให้คุณนอนหลับไม่สนิท
Loneliness -ความเหงา
The small study of 95 adults in South Dakota shows that people who perceived themselves as lonely had more fragmented sleep (which affects sleep quality, but not total sleep amount) than people who didn't think they were lonely. The findings mirror a 2002 study that showed that college students who felt lonely also had more fragmented sleep. 

High Altitude- พื้นที่สูงๆ
"When you're in high altitude, the air becomes thinner, and when the air is thinner, we breathe irregularly," Decker told HuffPost. "As we breathe irregularly, that causes our brain to wake up from sleep and have disruptive sleep."

A 2002 study conducted by researchers from the Mayo Clinic shows that 53 percent of pet owners reported they had disrupted sleep every single night, although only 1 percent of the pet owners said that their sleep was interrupted by more than 20 minutes a night because of the pet, ScienceDaily reported. 
In addition, 21 percent of the pet owners said their dogs snore at night, and 7 percent said their cats snore at night. 
"Pets in the bedroom can disrupt sleep because of the noise they make," Decker said. 

Working The Night Shift ทำงานกะกลางคืน
Decker explained that the problems that come with working during the nighttime and sleeping during the daytime occur because of our body's sensitivity to light, and the cues we take from light to signal sleep time. 
"Light and dark are cues that help synchronize our circadian system to our environment," Decker said. 

Room Temperature อุณหภูมิห้อง
In the evenings, our core body temperature begins to drop, Decker said, and that drop in temperature is the signal that it's time to go to sleep. Taking a hot bath or drinking something warm raises their core body so that it's able to drop and people are able to get that physiological cue for sleep, he said. 

As the night goes on and the morning begins to approach, our body temperature begins to gradually increase, until it reaches the room temperature and signals our brains to wake up, Decker explained. 

"So if a room is too warm, our body temperature can actually increase," and can lead to us waking up, he said. "Keeping the room cool helps ensure that we have a better quality of sleep and that we allow our brain temperature mechanisms to do what they're supposed to do." 

It's also possible to have affected sleeping if the room is too cold, too, WebMD reported.
