Why do you often yawn?
Yawning is a common physiological phenomenon, but frequent yawning may hide health problems. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze the reasons for frequent yawning, relevant research data and coping methods.
1. The physiological mechanism of yawning
Yawning is the body's natural response to increasing blood oxygen levels by taking a deep breath. Studies have found that yawning can also help regulate brain temperature and signal fatigue or boredom in social situations.
| Yawn triggers | incidence | duration |
|---|---|---|
| tired and sleepy | 68% | 5-8 seconds |
| Environmental hypoxia | 22% | 3-5 seconds |
| social contagion | 45% | 4-7 seconds |
| brain temperature regulation | 31% | 6-9 seconds |
2. Six major reasons for frequent yawning
1.lack of sleep: The latest sleep study shows that if you sleep less than 6 hours for 3 consecutive days, the frequency of yawning increases by 300%.
2.hypoxic environment: When the carbon dioxide concentration in a confined space exceeds 1000ppm, the number of yawns increases significantly.
3.drug effects: Antidepressants, antihistamines, etc. can interfere with neurotransmitter balance
4.neurological diseases: Early symptoms of multiple sclerosis, epilepsy and other diseases
5.Abnormal body temperature regulation: A 0.5°C increase in brain temperature triggers the yawn reflex
6.psychological factors: People with anxiety disorders yawn 2-3 times more often than ordinary people.
| Crowd classification | Average number of yawns per day | peak hours |
|---|---|---|
| healthy adults | 5-15 times | 10-11 am |
| sleep deprived | 20-30 times | 2-4pm |
| depression patients | 30-50 times | Lasts all day |
| Neurological disease patients | 50+ times | After waking up in the morning |
3. The latest research findings in 2023
1. Harvard University research has confirmed that yawning can promote cerebrospinal fluid circulation and help clear beta-amyloid (a marker of Alzheimer’s disease)
2. Experiments at the University of Tokyo show that cooling the forehead can reduce the number of yawns by 57%
3. The journal "Sleep Medicine" points out that a 20-minute midday nap can reduce afternoon yawns by 72%.
4. 5 ways to deal with frequent yawning
1.Improve sleep quality: Get 7-8 hours of sleep and avoid using electronic devices 1 hour before going to bed.
2.Increase oxygen intake: Take 3-5 deep breaths every hour and place green plants in the office
3.regulate body temperature: Drinking warm water (around 60℃) can reduce yawning better than cold water
4.moderate exercise: 30 minutes of aerobic exercise a day can increase blood oxygen saturation by 15%
5.medical examination: If it is accompanied by symptoms such as headache and dizziness, a neurological examination is required
| Improvement methods | Effective time | efficient |
|---|---|---|
| Regular schedule | 3-7 days | 89% |
| Increase water intake | 1-2 days | 67% |
| Office ventilation | immediately | 92% |
| chewing gum | within 5 minutes | 78% |
5. Abnormal yawning that needs to be alerted to
It is recommended to seek medical treatment promptly when the following situations occur:
• Yawning more than 10 times per hour for more than 3 days
• accompanied by facial numbness or limb weakness
• Frequent yawning despite getting enough sleep
• Chest pain or difficulty breathing when yawning
The latest medical research shows that abnormally frequent yawning may be one of the precursor symptoms of stroke. According to data from the American Heart Association, 23% of ischemic stroke patients experience increased yawning 72 hours before the onset of stroke.
It can be seen from the above analysis that although yawning is a normal physiological phenomenon, abnormal frequency may indicate health problems. Only by maintaining good living habits and paying attention to the signals sent by your body can you better maintain your health.
