Key takeaways
- Get morning daylight and stay up until a sensible local bedtime on day one.
- Drink water steadily through the journey and go easy on alcohol on the plane.
- Keep naps short, eat at local mealtimes and plan a gentle first 48 hours.
- An Energy & Jet Lag drip is an optional top-up, not a substitute for sleep and light.
Getting to Koh Lanta is part of the adventure, but it is a long one. If you are flying in from Europe or Australia, you may land feeling foggy, wide awake at 3am or ready to sleep at lunchtime. These jet lag Thailand tips are designed to help you reset your body clock quickly so you can enjoy the island rather than drift through it.
Nothing here needs special equipment. Light, sleep, food and fluids do most of the work.
Why does jet lag hit so hard on the way to Thailand?
Jet lag happens when your internal body clock is out of step with local time. Your sleep, hunger, alertness and even digestion run on that clock, and it only shifts gradually. Crossing several time zones in one go leaves it lagging behind.
Travellers from Europe usually fly east to Thailand, which many people find harder because you need to fall asleep earlier than your body expects. Australians cross fewer time zones, but a long day of travel still leaves people tired.
On top of the time difference, the journey itself takes a toll. Dry cabin air, broken sleep, airport food and long periods of sitting all add to that drained feeling. Then you step into tropical heat and humidity.
The journey to Koh Lanta: what to expect
Most visitors arrive in Thailand on a long-haul flight, often with a connection, then fly on to Krabi. From Krabi, it is a road transfer down to the coast and a short car ferry across to the island. Many people arrive in Saladan, at the northern end, before heading on to their accommodation in Klong Dao, Long Beach, Kantiang Bay or elsewhere.
It all adds up to a long day. Planning for that, rather than expecting to bounce straight into a busy schedule, makes a real difference.
On the plane
- Set your watch to Thai time when you board and start thinking in local hours.
- Drink water regularly. Cabin air is dry and it is easy to fall behind.
- Limit alcohol and caffeine, both of which can disturb sleep and add to dehydration.
- Sleep if it is night-time in Thailand; try to stay awake if it is daytime.
- Walk the aisle and stretch now and then.
On the transfer and ferry
Keep a bottle of water and a light snack with you for the drive and the ferry. It is tempting to nap in the car, but a short doze is better than a deep sleep if it is still daytime.
Your first 48 hours on Koh Lanta: a simple plan
Day one
- Get outside in daylight. Light is the strongest signal for resetting your body clock. A walk along the beach or a coffee on a shaded terrace counts.
- Eat at local mealtimes, even if you are not very hungry. Something light and familiar is fine.
- If you must nap, keep it short, ideally under 30 minutes and not late in the afternoon.
- Watch the sunset from a west-coast beach. It is a lovely way to mark the end of the day for your brain as well as your camera.
- Go to bed at a normal local time, in a cool, dark room.
Day two
- Get up at a reasonable time, even after a broken night, and get morning light again.
- Plan gentle activity: a swim, a short walk or a relaxed trip to Lanta Old Town.
- Keep drinking water and eat regular meals.
- Save big days, such as dive trips and long island tours, for later in the week.
Koh Lanta tip: Mornings on Koh Lanta are usually cooler and calmer than midday. An early beach walk gives you bright daylight to help your body clock without the full force of the afternoon heat.
How can you sleep better in the heat?
Heat and humidity can make it harder to fall asleep, especially when your body clock is already confused. A few simple steps help:
- Use air conditioning or a fan, and keep curtains closed during the day.
- Take a cool shower before bed.
- Avoid heavy meals and plenty of alcohol late in the evening.
- Put your phone away for a while before sleeping.
- If you wake in the night, stay calm, keep the lights low and rest rather than scrolling.
Some people use melatonin for jet lag. Rules and availability vary between countries, so speak to a doctor or pharmacist before trying it, particularly if you take other medicines.
Can an IV drip help with jet lag?
An IV drip cannot reset your body clock; only light, sleep and time do that. What it can do is help you rehydrate after a long journey and top up some vitamins while you rest in your room.
Our Energy & Jet Lag drip contains vitamin B12, B complex and magnesium with fluids, and no caffeine. A registered nurse comes to your accommodation, runs a quick health check and stays with you for around 45 to 60 minutes. Many guests like it as a calm way to start the trip, then head out for daylight afterwards.
If you would like to know more about the visit itself, see how it works.

Shake off the journey and start your holiday with energy. A registered nurse comes to your villa, hotel or bungalow anywhere on Koh Lanta.
When is it more than jet lag?
Tiredness, poor sleep, mild headaches and a slightly off appetite are normal after a long flight and should ease within a few days. Some symptoms are not jet lag and need prompt attention.
When to get medical help
When to get medical help. Long flights slightly raise the risk of blood clots. Seek urgent help if you have a painful, swollen or warm calf, sudden breathlessness, chest pain or coughing up blood. Also get help for a high fever, confusion, fainting or severe headache. Call 1669 for an ambulance or go straight to hospital. Koh Lanta Hospital is near Lanta Old Town, and larger hospitals are in Krabi Town.
Bringing your body clock to island time
Most people find they feel settled within a few days, especially if they get morning light, eat at local times and keep the first couple of days gentle. Drink steadily, rest well and save the big adventures until you feel like yourself.
If you would like a nurse to visit on your arrival day, message us on WhatsApp and we can talk through whether it suits you.
