A practical guide to using light, local-time habits, food and movement, and optional magnesium or glycine support to settle after travel and rebuild a consistent sleep schedule.
Jetlag happens when your sleep-wake timing is still following your old time zone while the clock, light, meals, and responsibilities around you have moved ahead. You can feel tired in the afternoon, wide awake at local bedtime, hungry at unusual hours, or foggy the next morning. The fastest route back is to give your body the same local-time signals every day.
Natural remedies for jetlag work best when they reinforce those signals. Morning light, a fixed wake time, sensible caffeine timing, and a short evening wind-down do more to move the schedule than adding several sleep products at once. Supplements can support the parts of the night that feel difficult, such as tight muscles, slow sleep onset, or a restless evening.
Why jetlag makes sleep feel out of place
Sleep is controlled by two overlapping pressures. One builds the longer you stay awake, while the other follows a daily rhythm that expects light and activity at certain times. Long-distance travel changes the local day suddenly, but the daily rhythm needs repeated cues before it catches up.
Eastward travel is often harder because it asks you to fall asleep and wake earlier than usual. Westward travel usually asks you to stay awake later. The direction matters, but the same basics help in both cases: wake at a chosen local time, get light at the right part of the day, avoid long naps, and keep the evening low stimulation.
Expect a few imperfect nights after a large time-zone change. The useful question is whether the schedule is moving in the right direction. A wake time that becomes more predictable, earlier morning alertness, and less time spent awake at local bedtime are better signs than one perfect night.
Start with light and a fixed wake time
Light is the strongest everyday cue for your body clock. Use the destination time as soon as you can. After an eastward trip, seek outdoor light soon after your planned wake time and keep the evening dim. After a westward trip, later-day light is useful for staying awake until the new bedtime, while very early light may pull the schedule earlier than you want.
Use bright light intentionally rather than staring into a bright lamp at random hours. The timing of light changes the direction in which your schedule moves. Outdoor daylight is the simplest first step. If you are considering a light box, follow the device instructions and ask a qualified healthcare professional for guidance if you have an eye condition, take medicines that increase light sensitivity, or have a history of mood episodes affected by sleep loss.
Pre-travel adjustment can help when your itinerary is predictable. In a 2003 randomized study by Burgess and colleagues in the Journal of Biological Rhythms, healthy adults moved their sleep and wake times one hour earlier each day for three days before eastward travel. Groups using bright light in the morning advanced their circadian timing by 1.5 to 2.1 hours, compared with 0.6 hours under dim indoor light.1 You do not need to copy the laboratory setup to use the principle: bring bedtime and wake time toward the destination gradually, then make morning light part of the routine.
Evening support for a changing sleep schedule
Choose the product that matches the part of your night that needs support while your local-time routine settles.
The natural remedies that reset the day
Use a few strong cues consistently instead of trying every remedy at once. The following routine works for travel and for a sleep schedule that drifted during a busy week.
Get outside after waking
Step outdoors soon after your chosen wake time, even if you do not feel sleepy at night yet. A short walk adds movement and daylight without making the morning feel like a treatment session. Keep the timing steady across weekdays and weekends while you are resetting.
Eat on local time
Move breakfast, lunch, and dinner toward the destination schedule. A heavy meal at 2 a.m. tells your body that the old time zone is still in charge. If you land at an awkward hour, choose water and a light snack, then wait for the next local meal rather than turning the whole night into a second dinner.
Use caffeine early
Caffeine is useful for the first part of a local morning, but late doses can keep the old schedule alive. Set a cutoff based on bedtime and move it earlier if sleep remains light. Do not use a large evening serving to push through the first tired day after travel.
Keep naps short
If you need a nap, take it early and keep it brief. A long late-afternoon sleep removes the pressure that would otherwise help you reach local bedtime. When the urge to sleep is strong, a short nap followed by daylight and a little movement is easier to recover from than sleeping until dinner.
Make the last hour boring
Dim the room, finish work messages, lower the temperature if the room is warm, and keep your phone away from the bed. A shower, light reading, stretching, or quiet music gives the evening a repeatable shape. The goal is to make bedtime predictable, not to force sleep on command.
Where magnesium and glycine fit
Once the daytime cues are in place, an evening supplement can help with the specific part of sleep that feels out of sync. Magnesium bisglycinate and glycine are single-ingredient formats, which makes the choice simpler than with a blend that hides amounts.
Magnesium bisglycinate is relevant when travel leaves you with tight muscles, frequent waking, or a body that has trouble winding down. A typical supplement dose is around 90–100 mg of elemental magnesium taken 15 to 30 minutes before bedtime. A 2023 systematic review by Arab and colleagues in Biological Trace Element Research found that observational studies linked magnesium status with several sleep measures, while randomized trials of supplementation reported inconsistent results.2 Keep expectations practical and judge by your own evening routine. Deep Rest is one example of a clean-label magnesium bisglycinate product.
Glycine is relevant when the main problem is taking too long to fall asleep or waking with morning brain fog. In a 2012 randomized placebo-controlled study by Bannai and colleagues in Frontiers in Neurology, 3 g of glycine before bed reduced next-day fatigue in healthy adults during three nights of partial sleep restriction.3 A supplement like Dream On provides that studied dose. Glycine also supports the body's natural drop in core temperature around bedtime, relevant when a racing mind makes sleep onset drag on.
If both muscle tension and slow sleep onset are problems, magnesium bisglycinate and glycine can be taken together. They do not compete, and neither is habit-forming. Start with whichever matches the bigger problem. Add the second later only if a gap remains.
Which supplement matches your night
Jetlag does not create the same problem for everyone. Use the table to identify the better fit, then keep the rest of the routine stable so you can tell what is helping.
| What you notice | Start with | Typical evening dose |
|---|---|---|
| Tight muscles, frequent waking, hard evening wind-down | Magnesium bisglycinate | ~90–100 mg elemental magnesium, 15–30 min before bed |
| Slow sleep onset, morning brain fog | Glycine | 3 g with water before sleep |
| Both patterns are present | Magnesium bisglycinate + glycine | Same as above for each |
Use one consistent serving. Do not double up because one night went badly. If you take medication, have a chronic condition, are pregnant or nursing, or have reacted to supplements before, speak with a qualified healthcare professional before adding a new product.
A seven-day plan for fixing your sleep schedule
Use the first week to make the timing boring and repeatable. Record your destination wake time, bedtime, first outdoor light, last caffeine, nap length, and how refreshed you felt. The notes do not need to be precise. They only need to show whether the schedule is moving.
Days 1 and 2: anchor the morning
Choose a wake time you can keep for the next week. Get outside after waking, eat the first meal on local time, and keep caffeine to the earlier part of the day. If you arrive after a long flight and feel exhausted, use a short early nap rather than sleeping through the afternoon.
Days 3 and 4: move the evening earlier or later
For eastward travel, start dimming the evening earlier and avoid bright indoor light close to bedtime. For westward travel, use normal indoor activity and later-day light to stay awake until the local bedtime. Keep meals, exercise, and caffeine in the same local-time pattern.
Days 5 to 7: keep the signal steady
Do not change the plan because one night was poor. Keep the wake time, daylight, caffeine cutoff, and evening routine steady. This is the point at which you judge whether magnesium bisglycinate, glycine, or both fits the specific issue you are still noticing.
Keep the schedule as the foundation and the supplement as a small part of the evening. If sleep remains severely disrupted, daytime sleepiness makes driving or work unsafe, or the problem continues after the travel adjustment period, consult a qualified healthcare professional rather than escalating a supplement dose.
Frequently Asked Questions
What is the best natural remedy for jetlag?
Start with local-time cues: a fixed wake time, outdoor light after waking, local meals, earlier caffeine, short naps, and a dim final hour. These habits address the timing problem directly.
Should I sleep when I land?
Sleep according to the destination clock when possible. If you cannot stay awake safely, take a short early nap and get up rather than sleeping through the rest of the day.
Is morning light better after an eastward flight?
Morning light is a useful cue when you are trying to move the schedule earlier. Use it after your chosen local wake time and keep late evening light low. If you are unsure about the timing or have a light-sensitive condition, ask a qualified healthcare professional.
Should I choose magnesium or glycine for jetlag?
Choose magnesium bisglycinate when muscle tension, frequent waking, or evening wind-down is the main issue. Choose glycine when falling asleep and morning freshness are the main issues. Both can be taken together when both patterns are present.
When should I take magnesium or glycine?
Magnesium bisglycinate is typically taken 15 to 30 minutes before bedtime. Glycine is taken before sleep, mixed with water. Keep the timing consistent and do not double the serving after a missed dose.
How long does it take to fix a sleep schedule?
It depends on the size of the time-zone change, travel direction, and how consistently you use local-time cues. Look for a trend over several days rather than expecting one night to erase the shift.
Can I combine magnesium or glycine with other supplements?
Magnesium bisglycinate can be taken with most other supplements, but medication use, pregnancy, nursing, chronic illness, and prior reactions call for professional guidance before combining products.
