While a daily low-dose aspirin can slash the risk of heart attacks and strokes in those with an elevated risk, it can also cause dangerous bleeding in the stomach and intestines. Drugs called NSAIDs, which include ibuprofen (Advil and generics) and naproxen (Aleve and generics), can magnify that risk.
Yawns can be caused by boredom. When watching an uninteresting performance, movie, or recital a person may have a bout of excessive yawning. To suppress the yawns, he can hold his mouth closed tightly and clench his jaws. When the yawn comes on he must keep the pressure in the rear of his jaws and swallow the yawn. Excessive yawning, caused by sleepiness, can be counteracted by drinking lots of water. Dehydration is a big cause of fatigue. When a person drinks a lot of water, the yawning will cease. Every time the urge to yawn is strong, drink a big gulp of water and the yawn will pass.
In fact, yawning is usually triggered by sleepiness or fatigue. Some yawns are short, and some last for several seconds before an open-mouthed exhale. Watery eyes, stretching, or audible sighs may accompany yawning. Researchers arenât exactly sure why yawning occurs, but common triggers include fatigue and boredom. Yawns may also occur when you talk about yawning or see or hear someone else yawn. It is believed that contagious yawning may have something to do with social communication.
