Natural remedies for jet lag

Natural remedies for jet lag (time zone change)

You landed in New York, Bangkok, or Los Angeles after a ten-hour flight and need to function normally, but your body thinks it’s midnight. You feel dizzy, tired, hungry at strange hours, and unable to sleep when you should. This is the classic experience of jet lag, a phenomenon that more and more Romanians experience as international flights and travel abroad multiply.

Jet lag, or time zone change syndrome, occurs when you rapidly cross multiple time zones, and your internal biological clock, called the circadian rhythm, lags behind local time. Your body operates on an approximately 24-hour cycle, regulated by light, eating, physical activity, and hormonal factors. When you suddenly arrive in an area with different hours, this cycle becomes unbalanced and it takes you whole days to adapt.

Fortunately, there are proven strategies to reduce the effects of jet lag and accelerate adaptation. From melatonin, which the body naturally produces, to strategic sun exposure, to adjusting nutrition and hydration, we have an entire arsenal at our disposal. Whether you’re going on vacation, a business trip, or to family, these tips can help you make the most of every day.

What jet lag is and why it occurs

To understand jet lag, we must first understand the circadian rhythm. This is an internal biological clock, located mainly in an area of the brain called the suprachiasmatic nucleus. This “clock” regulates dozens of physiological processes: hormone production, body temperature, appetite, metabolism, attention, and of course, sleep.

The circadian rhythm is regulated mainly by natural light. When it gets dark, the pineal gland begins producing melatonin, the hormone that prepares the body for sleep. When it gets light, production stops and cortisol and other substances that wake us up are released.

When you travel rapidly between time zones, light and activities change dramatically, but the internal clock doesn’t adapt immediately. For each hour of difference, your body needs approximately one day of adaptation. So a flight from Bucharest to New York (7 hours difference) can require a week of complete acclimatization.

What influences jet lag severity:

  • Number of time zones crossed (over 3-4 is clearly felt)
  • Direction of travel (east harder than west)
  • Age (people over 50 adapt more slowly)
  • General state before the flight (fatigue, stress)
  • Hydration and nutrition during flight
  • Travel frequency (those who fly often adapt more easily)

Symptoms of time zone change

Jet lag isn’t just fatigue. It’s a complex set of symptoms that can affect multiple aspects of your functioning:

Sleep symptoms:

  • Insomnia at sleep time
  • Very early waking, unable to fall back asleep
  • Fragmented, poor quality sleep
  • Excessive daytime sleepiness

Cognitive symptoms:

  • Difficult concentration
  • Poor short-term memory
  • Slow reactions
  • Frequent mistakes in usual activities
  • Confusion, “brain fog”

Digestive symptoms:

  • Hunger at strange hours (3-4 AM or afternoon)
  • Lack of appetite at normal hours
  • Constipation or diarrhea
  • Indigestion
  • Bloating

General symptoms:

  • Persistent fatigue
  • Headaches
  • Irritability
  • Mild depressive mood
  • Diffuse muscle pain
  • Abnormal sweating
  • Variable blood pressure

Intensity and duration depend on individual factors. In some people, jet lag is just mild discomfort that passes in a few days. In others, it can become a serious problem that affects vacation quality or business travel performance.

Why some adapt more easily

There are significant differences between individuals in their ability to adapt to time zone changes. Factors include:

Genetic: Certain genes (PER3, CLOCK) influence how rigid or flexible the internal clock is. People with flexible circadian rhythm adapt more easily.

Chronotype: “Morning” people (those who wake up early naturally) adapt better to eastbound flights. “Night” people prefer westbound flights.

Age: Children and young people adapt remarkably quickly. After 50, adaptation takes longer due to decreased melatonin production.

Health status: People without chronic sleep problems, with normal weight and physically active, have milder jet lag.

Travel frequency: Pilots, flight attendants, international businessmen develop personal strategies and certain resilience.

Travel anxiety: Those who sleep poorly on planes due to fear or stress have more severe jet lag.

East vs west: which direction is harder

A generally accepted rule is that eastbound flights (which shorten the day) are harder than westbound ones (which lengthen the day).

Why it’s harder going east:

  • You have to go to bed “earlier” than your internal rhythm dictates
  • The natural circadian rhythm is approximately 24.2 hours, so the body naturally prefers to delay, not advance
  • Example: Bucharest to Tokyo flight (6 hours difference east). At 10 PM local, your body thinks it’s only 4 PM.

Why it’s easier going west:

  • The body “adds” hours, which is more natural
  • You can stay awake longer without problems
  • Example: Bucharest to New York flight (7 hours difference west). At 10 PM local, your body feels it could stay awake a few more hours.

Adaptation strategy:

For eastbound travel (Asia, Australia):

  • 3-4 days before, go to bed 1-2 hours earlier
  • At destination, force early bedtime even if not sleepy
  • Avoid long daytime naps
  • Expose yourself to morning light early

For westbound travel (America, Canada):

  • 2-3 days before, go to bed 1-2 hours later
  • At destination, stay awake until local bedtime
  • A short nap (20-30 minutes) in the afternoon is ok
  • Expose yourself to evening light

Remedy 1: Melatonin, the sleep hormone

Melatonin is the central hormone of the circadian rhythm, produced naturally by the pineal gland. For jet lag, orally supplemented melatonin is the treatment with the most scientific evidence of effectiveness.

How it works:

Melatonin signals the body that it’s time to sleep. When taken at the right time, it helps adjust your internal rhythm to the new time zone. If you arrive in an area where it’s early evening (local calendar), but your body thinks it’s still day, melatonin “tells” your body it’s time to prepare for rest.

Recommended dosage:

  • Effective dose: 0.5 to 5 mg
  • Contrary to intuition, small doses (0.5-1 mg) are often as effective as large ones
  • Very large doses (over 5 mg) are not more effective and can cause headaches and dizziness

When to take it:

For eastbound travel:

  • In days before the flight, take it 2-3 hours before usual bedtime at the new zone
  • At destination, take it at 10 PM local, for 3-5 days

For westbound travel:

  • At destination, take it only if you wake too early and can’t fall back asleep
  • Not necessary in all cases for westbound flights

Melatonin is available as:

  • Food supplement (without prescription) at pharmacies and natural stores
  • Preparations with doses between 0.3 mg and 5 mg
  • Extended-release tablets (more suitable for those who wake at night)
  • Liquid or sublingual forms (faster absorption)

Warning:

  • Don’t drive after taking melatonin
  • Don’t combine with alcohol or sedatives
  • Pregnant and breastfeeding women should consult a doctor
  • Some patients with autoimmune diseases shouldn’t take it
  • It’s not a sleeping pill but a rhythm regulator

Remedy 2: Sunlight, the natural clock

Light is the most powerful circadian rhythm synchronization factor. Strategic exposure to natural light can dramatically accelerate adaptation to a new time zone.

How it works:

Light receptor cells in the eyes send signals to the brain, which regulates melatonin, cortisol, and other hormones production. Morning light “sets” the internal clock and makes you alert for the rest of the day.

Practical strategies:

At eastern destination:

  • Go out in the sun immediately in the morning, at least 30 minutes
  • Avoid sunglasses in the first hours
  • Breakfast by the window, in light
  • Morning walk in a park or by water
  • Avoid strong evening light (including screens)

At western destination:

  • Exposure to light in evening, not immediately in morning
  • Stay awake with bright light until local bedtime
  • Avoid very early morning light (may worsen the problem)
  • Use good blinds at night

Light therapy lamps:

In severe cases or when traveling often, a light therapy lamp (10,000 lux) can be the ideal investment. 30 minutes in the morning equals sun exposure and helps enormously with regulation. They cost between 50-150 dollars and can be found at electronics stores or online.

Remedy 3: Proper hydration

Airplane cabin air is extremely dry, with humidity below 20%. During a long flight, you can lose up to 2 liters of water just through breathing and skin. This dehydration worsens jet lag symptoms: fatigue, headaches, mental fog.

How much to drink:

  • Before flight: 500 ml in the last hour
  • During flight: 200-250 ml every hour
  • After landing: 1-2 liters in first hours

What to drink:

  • Still water, the best option
  • Caffeine-free herbal teas
  • Coconut water (natural electrolytes)
  • Diluted natural juices

What to avoid:

  • Coffee (diuretic, worsens dehydration)
  • Alcoholic drinks (dehydrates and disrupts sleep)
  • Fizzy sodas (excess sugar)
  • Energy drinks

Flight attendant trick:

Take an empty 1-liter bottle and ask the flight attendant to fill it. You ensure you drink enough and avoid small cups. Many airports have water fountains after security.

Remedy 4: Strategic nutrition

Food is a second “clock” for circadian rhythm. When you eat influences as much as light.

Basic principle:

Start eating at destination time zone hours as soon as possible. This means sometimes you’ll skip meals or eat at “strange” hours for your stomach, but it’s essential for adaptation.

Foods that help:

Evening, for sleep:

  • Turkey (contains tryptophan, melatonin precursor)
  • Bananas (magnesium, potassium)
  • Walnuts, almonds (natural melatonin)
  • Cherries (melatonin)
  • Whole grains
  • Warm milk (tryptophan)

Morning, for energy:

  • Eggs (proteins with tyrosine)
  • Yogurt with fruits
  • Fatty fish (omega-3)
  • Vitamin C fruits (oranges, kiwi)
  • Coffee (but only in morning!)

To avoid before sleep:

  • Heavy meals
  • Excess sugar
  • Alcohol (may cause sleep but disrupts quality)
  • Caffeine after 2-3 PM
  • Spicy or acidic foods

Intermittent fasting and jet lag:

There is an interesting strategy: 14-16 hour fast before landing and first meal at destination, at local breakfast time. Some researchers suggested this “resets” the internal clock more quickly. Not for everyone, but worth trying.

Remedy 5: Scheduled sleep

Strategic sleep management is essential. It’s not just how much you sleep but when.

Naps:

  • Allowed: 20-30 minutes, no more
  • Right moment: afternoon, never late evening
  • Don’t sleep 3-4 hours during day, you’ll disrupt night sleep

Evening routine:

  • Applied at local bedtime, regardless of how you feel
  • Dark and cool room (18-20 Celsius)
  • No screens 1 hour before (blue light blocks melatonin)
  • Relaxing warm bath
  • Calming herbal tea (valerian, linden, chamomile)
  • Good book (not thrillers that activate you)

Strategic wake-up:

  • Alarm at local wake time
  • If you wake earlier, don’t stay in bed
  • Go out into light as quickly as possible
  • Breakfast at normal local time

Natural sleep aids:

  • Magnesium (200-400 mg evening)
  • Valerian or passiflora tea
  • Lavender essential oil in diffuser
  • Meditation or relaxation apps

Strategies before the flight

Proper preparation significantly reduces jet lag impact.

A week before:

  • Make sure you’re rested, not overloaded with work
  • Start gradually adjusting bedtime (1 hour per day)
  • Hydrate more than usual
  • Take vitamins, especially B complex
  • Avoid major stress

2-3 days before:

  • Quality sleep (7-9 hours)
  • Moderate physical activity
  • Avoid alcohol and heavy meals
  • Pack your bags with time to avoid last-minute stress

Flight day:

  • Normal breakfast, then light meals
  • Hydrate abundantly
  • Arrive at airport early, without stress
  • Walk as much as you can in the airport
  • Don’t drink coffee if flying at night

What to take in cabin baggage:

  • Water bottle (fill after control)
  • Healthy snacks (nuts, dried fruits)
  • Eye mask
  • Earplugs or active headphones
  • Comfortable neck pillow
  • Light blanket
  • Moisturizer, lip balm
  • Personal hygiene products
  • Comfortable change of clothes
  • Melatonin, magnesium, vitamins

Strategies during the flight

The flight itself can be used as an adaptation tool.

Clock adjustment:

Immediately after takeoff, set your watch to destination time. Live mentally at the new time.

Food:

  • Airplane meals usually follow destination time
  • If not hungry, don’t force, but try to eat a little at local meal time
  • Avoid heavy or very salty meals

Movement:

  • Get up every 1-2 hours and walk through the plane
  • Do stretching exercises in your seat
  • Move toes, roll ankles
  • Prevents deep venous thrombosis

Sleep on plane:

  • Sleep if it’s night at destination
  • Resist sleep if it’s day at destination
  • Eye mask, headphones for noise
  • Most comfortable position possible
  • Don’t take strong sleeping pills (thrombosis risk)

Hydration:

  • Water every hour
  • Avoid alcohol entirely
  • Limit coffee
  • Hand cream, thermal water spray for face

Strategies after landing

First days at destination are crucial.

First day:

  • Respect local time (meal, sleep, activity)
  • Don’t sleep more than 20-30 min if very tired
  • Go outside in light
  • Short walk, not intense sport
  • Hydrate continuously
  • Light food

Second day:

  • Normal activities at local time
  • Go out in morning light
  • Avoid alcohol another 1-2 days
  • Moderate sport if feeling well

Days 3-5:

  • Gradual adaptation to normal schedule
  • Increasing productivity
  • Better sleep
  • At 5-7 days, most people are fully adapted

Adaptogenic plants that help

Adaptogenic plants help the body cope with stress and fatigue. They can be valuable allies in managing jet lag.

Ashwagandha (Withania somnifera):

  • Reduces stress and anxiety
  • Improves sleep quality
  • 300-500 mg in evening

Rhodiola rosea:

  • Reduces physical and mental fatigue
  • Improves concentration
  • 200-400 mg in morning

Siberian ginseng (Eleutherococcus):

  • Creates stress resistance
  • Energizes
  • 300-500 mg in morning

Valerian:

  • Calms nervous system
  • Favors sleep
  • Tea or capsules in evening

Schisandra:

  • Complex adaptogen
  • Supports liver functions
  • 500-1000 mg per day

Consult a doctor or pharmacist before using adaptogens, especially if taking other medications.

Frequently asked questions

1. From how many time zones do you feel jet lag?

From 3 time zones, symptoms are clearly felt. At 1-2 zones, most people adapt in one-two days without major problems. Over 5-6 zones, adaptation requires active strategies.

2. Children and jet lag - is it worse for them?

Paradoxically, children adapt faster than adults but can be more irritable in first days. Keep home routines (sleep, food) as much as possible at the new destination too. Children under 5 sometimes have more difficult adaptation.

3. Is melatonin safe for regular use?

For occasional use (a few days per trip), it is considered safe. For chronic use, data is limited. It doesn’t seem to cause physical dependence, but some people develop psychological dependence. For frequent travel, consult a doctor.

4. Are there differences between men and women in jet lag?

Studies suggest women may have slightly more severe jet lag, possibly due to hormonal fluctuations. In the luteal phase of the menstrual cycle, adaptation is harder. Pregnant women should consult a doctor before long trips with large time differences.

5. Can I combat jet lag with coffee?

Coffee is strategically useful, not as a general solution. A cup in the morning can help alertness, but in the afternoon it will disrupt sleep. Those very sensitive to caffeine should avoid it entirely in the first days.

6. Can jet lag cause long-term health problems?

Occasional jet lag doesn’t seem to have lasting effects. Chronic jet lag (in pilots, flight attendants, frequent businessmen) has been associated in studies with cognitive problems, chronic sleep disorders, increased risk of diabetes and cardiovascular problems. Important to take breaks and care for sleep between trips.

Conclusion

Jet lag is an inevitable challenge of the era of rapid travel, but with correct strategies its impact can be significantly reduced. The combination of melatonin, strategic light exposure, adequate hydration, intelligent nutrition, and sleep management can shorten adaptation from a week to just a few days.

The key is preparation. A traveler who knows what they’re doing, who hydrates properly on the flight, who takes melatonin at the right time and exposes themselves to light in the morning at destination will have a totally different experience from someone who just lands and hopes everything will be fine.

For those who travel frequently, developing a personal protocol is essential. Each body responds differently, so experiment and find the combination that works for you. Over time, you’ll learn to manage jet lag like a professional.

And don’t forget: even if the first days can be hard, the human brain is incredibly adaptable. In 5-7 days you’ll be fully integrated into the new temporal reality and you’ll be able to enjoy your trip fully.

Medical warning: This article is informational in nature. People with chronic diseases (diabetes, epilepsy, severe sleep disorders, autoimmune diseases), pregnant or breastfeeding women, and those taking medications should consult a doctor before using melatonin or adaptogens. If jet lag symptoms persist over 2 weeks or are accompanied by unusual symptoms (chest pain, vision disturbances, severe confusion), consult a doctor.
