A moving rainy-season itinerary: a bedtime routine built on the NHS sleep tips
Japan's rainy season runs from early June to mid July in most of the country. Using the NHS sleep tips, a five-row bedtime routine for a trip where grey, damp days are the norm.
Our research draws on the sources listed below. Lumuwala shares ownership with stores we may discuss, including Calm Eden. About our commercial relationships.
Japan Guide’s rainy season page says most of Japan has a rainy season from the beginning of June to mid July, and that it does not rain every day. A trip then has plenty of grey, damp days and an unfamiliar bed. The NHS does not cover rainy-season travel, so the routine below applies its general sleep tips to it. The routine is our own suggestion and has not been tested in a trial. General information, not medical advice.
What the NHS says
The NHS guidance says to go to bed and get up at similar times each day, including non-working days, and to try not to use phones, tablets or computers for an hour before bed. It says big meals near bedtime can make dropping off harder, that caffeine is in tea, coffee and some soft drinks, and that alcohol and nicotine are best avoided 1 to 2 hours before bed. It says regular exercise supports sleep, that small amounts count, and that evening exercise that disrupts your sleep can be moved earlier in the day.
The routine
| Part of the day | What to try | Basis |
|---|---|---|
| Bed and wake times | Keep them similar every day of the trip, travel days included | NHS: similar times each day, including non-working days |
| After a late train or a long sightseeing day | No phone, tablet or computer for an hour before bed; read or listen to calm music | NHS: try not to use screens for an hour before bed |
| Dinner after sightseeing | Eat earlier or lighter if you can | NHS: big meals near bedtime can make dropping off harder |
| Tea, coffee and drinks | Switch to a warm milky drink or herbal tea in the evening; leave alcohol 1 to 2 hours before bed | NHS: caffeine is in tea, coffee and some soft drinks; avoid alcohol 1 to 2 hours before bed |
| A day of weather changes | Do the walk earlier in the day, not late | NHS: small amounts of exercise count; move evening exercise earlier if it disrupts sleep |
Our guides on sleeping in humid weather, jet lag and daylight, a wind-down after an evening walk in the rain and keeping a daylight walk when it rains go further.
A note on the umbrella
Calm Eden is a sister site of Lumuwala, under common ownership. A damp-day routine is easier when the walk still happens, which is the point of its guide to whether you need an umbrella in Japan. The Haven Umbrella listing mentions reflective strips and 30 carbon fibre ribs.
In short
- Keep bed and wake times similar, travel days included.
- No screens for an hour before bed, and an earlier, lighter dinner when you can.
- Alcohol and caffeine late in the day make it harder, according to the NHS page.

Common questions
Does the NHS say anything about evening drinks?
Yes. Its sleep page says caffeine is in tea, coffee and some soft drinks, suggests a warm milky drink or herbal tea instead, and says to avoid alcohol and nicotine 1 to 2 hours before bed.
How regular should my sleep times be?
The NHS says to go to bed and get up at similar times each day, including non-working days.
Why keep times the same on a trip?
The NHS says to go to bed and get up at similar times each day, including non-working days. A moving itinerary makes that harder, so fixing the times first is the simplest step.
Should I exercise on a rainy day?
The NHS says regular exercise supports sleep, that small amounts count and that if evening exercise disrupts your sleep you can move it earlier in the day.
Is this medical advice?
No. It is general information from one NHS page. If you often cannot sleep, ask a doctor.
