For many professionals and business travelers, long-distance flights or cross-time zone business trips have become commonplace. However, jet lag can cause many to experience symptoms such as insomnia, fatigue, mood swings, and decreased concentration. The question is: How can one recover quickly and maintain their performance in an unfamiliar environment?
Why does jet lag occur?
Jet lag essentially occurs when your body clock (circadian rhythm) becomes out of sync with the external environment.
This means you feel sleepy during the day when you should be awake. And even when you're tired, you can't fall asleep at night. Even digestion, hormone release, and cognitive performance can feel out of sync.
Research shows that circadian rhythms are primarily regulated by light, melatonin secretion, and the autonomic nervous system. After crossing time zones, it can take several days to a week for the brain and body to readjust.
Scientific Ways to Combat Jet Lag
1. Light
Get as much natural light as possible during the day to suppress melatonin and maintain alertness. At night, avoid bright light, especially blue light from phones and laptops.
2. Diet and Hydration
Avoid consuming caffeine or alcohol at inappropriate times, as these can disrupt sleep. Doctors recommend avoiding caffeine after 2 p.m. because it's not metabolized by the body before bedtime, significantly affecting sleep. Staying hydrated can also help reduce fatigue.
3. Melatonin and Breathing Exercises
Short-term use of melatonin supplements can help reset sleep rhythms.
Slow breathing exercises (approximately 6 breaths per minute) can enhance parasympathetic nerve activity, helping the body enter rest mode.
4. New Neuroscience Approach: taVNS
In recent years, transcutaneous auricular vagus nerve stimulation (taVNS) has been increasingly shown to aid sleep and fatigue recovery.
Autonomic Nerve Regulation: Studies have shown that taVNS can reduce sympathetic nervous system activity and enhance parasympathetic nervous system activity, thereby improving sleep quality and mood stability (Bretherton et al., Scientific Reports, 2019).
Cognitive Benefits: Another study found that taVNS can improve attention and information processing during periods of fatigue (Ventura-Bort et al., Neuropsychologia, 2018).
DreamPhone: A Portable Sleep Aid for Travelers
Powered by taVNS, the DreamPhone is designed for sleep and relaxation. For frequent travelers or business professionals, it offers the following key advantages:
Lightweight and Portable: The headband design eliminates pressure on the ears, making it comfortable to wear on airplanes and in hotels.
Quick Relaxation: Just 10 minutes before bed or during a flight can help your brain enter "rest mode," relieving travel-related stress and anxiety.
Efficient Recovery: Not only does it improve sleep, it also helps your body recover faster for better performance the next day.
Jet lag is an unavoidable part of modern life, but science offers effective strategies: light management, melatonin, breathing exercises, and now, neuroscience tools like taVNS.
For frequent travelers and business professionals, the DreamPhone is the ideal travel companion. It helps you relax and fall asleep naturally in unfamiliar surroundings, ensuring better recovery during limited rest time, making your travels and work more productive. Traditional sleep aids: Key points and limitations. White noise machines mask external sounds and don't relieve internal stress. Earplugs block noise and have no effect on brain wakefulness. Sleep apps teach relaxation. Screen time delays melatonin. DreamPhone (taVNS) directly modulates the nervous system and addresses the root causes of insomnia. 💤 The future of sleep lies in neurological relaxation. Technology can record, mask, and guide—but only neuroscience can truly reset the overactive brain that keeps you awake. With DreamPhone, you can not only manage your sleep but also retrain your brain to rest naturally. No drugs, no dependency, just science-backed calm.
