Insomnia: Self-Care Tips and When to See a Doctor | Causes of Sleeplessness During Travel

■Symptoms

Insomnia refers to difficulty falling asleep, waking up multiple times during the night, waking up too early in the morning, or feeling unrefreshed despite getting enough sleep. During travel, insomnia may occur temporarily due to jet lag, changes in environment, fatigue, or stress.

It may also be accompanied by daytime sleepiness, difficulty concentrating, headaches, fatigue, or dizziness. In most cases, insomnia is temporary, but occasionally it may be related to an underlying physical or mental health condition.

■Causes

Possible causes include:

• Sleep-related disorders such as sleep apnea
• Psychological stress, anxiety, or depression
• Physical symptoms such as fever, pain, or coughing that interfere with sleep
• Disruption of the body’s internal clock due to jet lag or environmental changes
• Effects of caffeine, alcohol, or certain medications

If insomnia is accompanied by shortness of breath, chest pain, severe anxiety, or symptoms that interfere with daily activities, we recommend seeking medical attention as a precaution.

■When to Seek Medical Attention

【Seek Medical Attention Promptly If You:】

• Have been unable to sleep properly for several days
• Experience shortness of breath or chest pain
• Have severe anxiety or palpitations
• Feel confused or unable to function due to sleep deprivation
• Cannot sleep because of fever or severe pain

【You May Monitor Your Symptoms If:】

• You are experiencing temporary sleep difficulties after starting your trip
• You can carry out normal daytime activities
• Your symptoms are gradually improving with rest
• You are sleeping less than usual but otherwise feel well

However, if your symptoms persist or you are concerned about your condition, we recommend consulting a healthcare provider as a precaution.

■Self-Care Tips

• Avoid caffeine and alcohol before bedtime
• Limit smartphone, tablet, and computer use before sleep
• Keep your room dark, quiet, and comfortable

• Maintain a regular daily routine and engage in light daytime activities

Avoid taking sleeping medications without medical advice or exceeding the recommended dosage.
