Because something is keeping the air from moving freely through the passages behind their noses and mouths. Maybe they have bad sleep posture, or maybe they’ve put on weight or have a sinus infection. Sometimes, snoring is brought on by age. Whatever the reason, snoring can get loud. A woman in England once snored loud enough to drown out the sound of a low – flying passenger plane!

Those who have enlarged tonsils, an enlarged tongue or excess weight around the neck are more prone to snoring. And structural reasons like the shape of one’s nose or jaw can also cause snoring. The snoring sound itself is a result of the narrowing of a person’s airway, which causes a throat vibration and the snoring sound. No matter the reason, 40% of normal adults snore regularly, whether they realize it or not.

Scientists aren’t really sure. Studies suggest that dreams help us cope with painful memories. Dreaming might also make us smarter and more creative during our waking hours. So if you’re feeling drained, grabbing 40 winks – and a few vivid dreams – might recharge your brain.

Dreams facilitate memory consolidation. New things learned during the day are reinforced by the firing of the new neuronal connections at night. But people don’t generally dream about a task they learned.

Dreams occur when specific neuron networks are activated. This is evidenced by neurocognitive research showing that during sleep neural activity only decreases by 10%. Without the neuron connections constantly firing, connections may degenerate. And thus, dreams are non-functional side effects of activation of networks that need to be activated to help keep the brain intact.

Doctors believe that good night’s sleep comes with many benefits, including improved creativity and mental sharpness. Avoid going to bed and you’ll soon suffer the consequences: crankiness, clumsiness – even hallucinations if you miss a few days. Your brain will go on strike, and easy tasks will become supremely difficult until you turn in and switch off.

If you continue to operate without enough sleep, you may see more long-term and serious health problems. Some of the most serious potential problems associated with chronic sleep deprivation are high blood pressure, diabetes, heart attack, heart failure or stroke. Chronic sleep deprivation can even affect your appearance.  Over time, it can lead to premature wrinkling and dark circles under the eyes. Also, research links a lack of sleep to an increase of the stress hormone cortisol in the body. Cortisol can break down collagen, the protein that keeps skin smooth.

Whenever you try to defeat drowsiness to finish one more Harry Potter chapter, you’re actually locked in a losing battle over bedtime with your brain stem. This chunk of gray matter at the base of your brain regulates your sleep, along with other automatic bodily functions such as breathing and the ticking of your heart.

When the stomach is full, then sleepiness will occur. This happens to many people. Sleepiness after eating is caused by many factors, such as the type of food you consume, messy sleeping habits, your health condition and so forth. Bad sleeping patterns can also cause sleepiness post-meal. After a meal, the body feels full and relaxed, making the body feel like it is resting, resulting in a feeling of sleepiness, particularly if you didn’t get a good night’s sleep the night before. 

To avoid this, improve your sleeping habits to prevent stress. Engaging in regular physical exercise can help you get a good night’s sleep. It is recommended that you avoid napping if you are having trouble sleeping at night.

You bet, at least among higher primates such as chimpanzees and bonobos (for the same reason as for humans, researchers suspect). Even more surprising, experiments show that dogs catch yawns from watching people!

When two groups of chimpanzees were shown videos of familiar and unfamiliar chimps yawning, the group watching the chimps they knew engaged in more contagious yawning. This study, by Matthew Campbell and Frans de Waal, supports the theory that yawning plays a role in the evolution of social bonding and empathy.

And dogs not only catch each others’ yawn, they are susceptible to human yawning as well. In one study, 29 dogs watched a human yawning and 21 of them yawned as well — suggesting that interspecies yawning could help in dog-human communication.

Absolutely! In fact, yawning is so contagious that even reading about yawning can make you yawn.(Go ahead and get it out of your system) Studies have shown again and again that people who see other people yawn – even in videos – are more likely to yawn. Yawning most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality. It is commonly associated with tiredness, stress, sleepiness, or even boredom and hunger. In humans, yawning is often triggered by others yawning (e.g. seeing a person yawning, talking to someone on the phone who is yawning) and is a typical example of positive feedback. This “contagious” yawning has also been observed in chimpanzees, dogs, cats, birds, and reptiles, and can occur across species.
