Spring sleep knows no dawn, Yawns come knocking at the door. Sleepless nights, Daytime drowsiness.
Spring fatigue, also known as "spring lethargy," is a well-known seasonal symptom that troubles the body—spring drowsiness, summer exhaustion, autumn drowsiness, winter hibernation.Spring's warmth unfolds, flowers bloom—a season brimming with vitality. Yet many struggle to muster energy, plagued by insufficient sleep and a foggy, heavy mind. Spring fatigue primarily stems from oxygen deprivation in the brain. As seasons shift, winter's relative chill causes skin sweat glands to contract, conserving body heat.As spring arrives and body temperature rises, the skin gradually relaxes, pores open, and sweat glands and blood vessels begin to dilate. This increases blood supply to the skin's surface and enhances cutaneous circulation, but relatively reduces blood flow to the brain. Insufficient oxygen supply to the brain impairs its functioning. Engaging in oxygen-intensive activities at this time can more easily trigger "brain hypoxia," severely disrupting the body's biological clock.
So how can we alleviate spring fatigue to boost work efficiency and quality of life?
Four Key Strategies to Combat Spring Fatigue
1. Maintain mental alertness through scientifically balanced nutrition. Breakfast should include carbohydrates as staples, such as whole-grain steamed buns. This helps stabilize blood sugar, prevent hypoglycemia, and alleviate fatigue while enhancing energy levels.Protein from lean meats, poultry, fish, and low-fat dairy products also boosts alertness and energy.
Increase intake of potassium- and vitamin C-rich fresh fruits and vegetables like kiwis, citrus fruits, oranges, lemons, grapefruits, strawberries, Chinese cabbage, tomatoes, and green peppers to meet your body's vitamin needs.Moderately supplement with B vitamins, essential for nerve function and metabolism. Limit greasy and heating foods; consume meat in moderation—100–150 grams daily is sufficient. Excessive meat consumption can acidify the body, leading to fatigue. Reduce alcohol intake, as excessive drinking causes drowsiness and disrupts normal sleep.
2. Adequate sleep nourishes liver blood. Poor sleep leads to liver blood deficiency, causing not only emotional changes but also potential issues with the nervous, digestive, and metabolic systems. Sleep is crucial—staying up late damages the brain, nervous system, and liver. Minimize late nights whenever possible.
Of course, more sleep isn't always better. Adults need about 8 hours daily. Excessive sleep reduces cerebral cortex excitability, putting it in an inhibited state that promotes drowsiness and lethargy, creating a vicious cycle of increased fatigue. Maintaining a regular schedule, sticking to set bedtimes, and taking short afternoon naps ensures adequate rest. This helps the body adapt to longer days and shorter nights, guaranteeing sustained energy levels.
3. Regular exercise enhances metabolic processes, boosts blood circulation and respiratory function, and stimulates the central nervous system. Spring is an ideal season for activities like ball games, swimming, walking, or hiking to promote blood flow, metabolic efficiency, and overall bodily function. Improving indoor air quality, ensuring ventilation, massaging temples, and sunbathing also help alleviate spring fatigue.When drowsiness strikes, apply Tiger Balm or peppermint oil externally, or drink coffee or tea to boost alertness.
4. A cheerful mood keeps bodily functions in optimal condition. Listening to upbeat, uplifting music or songs—singing or dancing along to the rhythm enhances the effect.Enjoying comedy shows, skits, or humorous programs and laughing heartily can stimulate the nervous system and dispel drowsiness. Additionally, moderate external stimuli like visual cues and light exposure help adjust the body's internal rhythm, rapidly activating the central nervous system to eliminate fatigue.
Friendly Reminder
Health expert Chen Banghua explains that general springtime drowsiness is a temporary physiological phenomenon caused by climate changes, particularly rising temperatures. However, severe cases may signal underlying health issues and warrant prompt medical attention.
Scenarios include:
While yawning occurs naturally with fatigue or sleep deprivation, persistent yawning in individuals with chronic conditions like hypertension, arteriosclerosis, coronary heart disease, or diabetes warrants serious attention. It may indicate worsening cerebral arteriosclerosis, where narrowing blood vessels cause chronic cerebral ischemia and hypoxia.
Clinical reports indicate that 80% of stroke patients experienced persistent yawning 5 to 10 days prior to onset.
Similarly, sudden excessive sleepiness in the elderly warrants investigation for potential brain pathologies, including cerebral inflammation, brain tumors, cerebral atrophy, cerebral arteriosclerosis, or cerebrovascular diseases.
Generally, springtime drowsiness subsides within five to ten minutes, restoring alertness. However, if episodes occur multiple times daily or more frequently, vigilance is warranted for conditions like "paroxysmal hypersomnia" or "sleep apnea syndrome."Particular caution is warranted when accompanied by pronounced daytime fatigue, weakness, excessive sleepiness, thunderous nighttime snoring, or even intermittent breathing cessation—prompt medical attention is essential.
