What Causes Jetlag?
Jetlag happens when your circadian rhythm (body clock) is out of sync with local time. Symptoms can include daytime sleepiness, broken sleep, irritability, and brain fog.
- Good news: Some ingredients may help you fall asleep on local time, relax tense muscles, ease nausea, and reduce stress while you adjust.
Before your flight, make sure you're also set up with the right gear — a good travel pillow and sleeping eye mask can make a big difference to how well you rest on the plane.
Melatonin: The Natural Sleep Hormone
- What it is: A hormone your body releases at night to cue sleep.
- Why it may help: Can nudge your body to sleep at your destination's bedtime.
- Typical timing: Commonly used in low doses (≈0.5–3 mg) around 30–60 minutes before local bedtime. Follow label directions and professional advice.
- Note: Not a sedative; more of a "clock setter."
Traveller story (Sydney → US): "Taking a low dose on the first few nights helps me fall asleep on local time."
