In this guide
A day spent walking between wet streets, with a bag in one hand and an umbrella in the other, can end with a sudden knot in the calf in the middle of the night. We read the NHS page on leg cramps and its sleep tips on 5 November 2026. The cramps page was last reviewed in December 2023 and is due for review in December 2026. It does not say that a long day on your feet causes cramps; the routine below is our arrangement of what it does say.
What the NHS says about leg cramps
- How common. Common, usually harmless and short-lived. They can happen at any time, but most people have them at night or when resting.
- What they feel like. A muscle in the leg tightens and causes a sudden pain that can make it hard to move, most often in the calf. They can last from a few seconds to 10 minutes, and the muscle can feel sore for up to 24 hours afterwards.
- During one. Stretching and massaging the muscle may ease the pain, although most go away on their own. Standing up and putting your weight on the leg may also help. Paracetamol or ibuprofen can ease soreness afterwards but will not help while it is happening.
- Possible causes. Ageing, strain on muscles during exercise (which can be worse in hot or humid weather), late pregnancy, certain medicines such as statins and diuretics, not drinking enough fluids and liver disease from heavy drinking. The reason for some is unknown.
- Prevention. Regular calf stretches may help but may not stop them completely.
The NHS calf stretch
Stand facing a wall with your arms out until your hands can just touch it, feet flat and standing up straight. Lean forward, pressing your hands to the wall until you feel your calves stretch, and hold for 2 or 3 seconds. Stand up straight again. The NHS says to repeat this a few times for 5 minutes, 3 times a day, the last time just before bed, and that if cramps reduce you may only need once or twice a day.
An evening routine after a day on foot
The order is ours.
- Drink some water through the evening. The NHS lists not drinking enough fluids among the causes.
- Do the wall stretch last thing. The NHS puts the third session just before bed.
- Keep the rest of the routine. Its sleep page says a calm bedtime routine helps, with no phones, tablets or computers for an hour before bed, and something relaxing such as reading, meditation or calming music.
- If a cramp wakes you. Stretch and massage the calf, stand and put weight on the leg, and do not expect painkillers to work in the moment.
- If you are still awake after. The NHS sleep page says not to force sleep: after around 20 minutes, get up and sit somewhere comfortable, and go back when you feel sleepy.
When the NHS says to see a GP
If cramps are disturbing your sleep, if you also have numbness or swelling in your legs, or if one lasts longer than 10 minutes. A GP will look for the cause and may suggest stretching exercises or, if exercise has not helped, quinine tablets, which are not suitable for everyone.
What the pages do not say
Neither page links cramps to walking, rain or any particular footwear, and the cramps page gives no number for how much water to drink. If you have a medical reason to avoid exercise, or cramps that keep coming back, ask your pharmacist or GP.

If the long walk is the commute, a compact umbrella that clips to a bag keeps a hand free. Calm Eden’s guide to the best umbrella for city commuting covers routes and wind, and its Haven Umbrella folds to 40 cm (15.75 in), weighs about 390 g and opens to about 105 cm, with a swivel carabiner handle that clips to a bag or a hook; the figures are the maker’s. It is storm-proof on a frame of 30 carbon fibre ribs, with an SPF 50+ canopy that blocks 99.99% of UV, a lifetime warranty and a 30 Day Money Back Guarantee that accepts opened or used umbrellas, with free returns. Every order includes a Haven Cover and the Wellness Journal (digital); Buy 2 Get 1 Free adds the UV Charm and the Rain Poncho, and Buy 3 Get 2 Free also adds the Haven SPF 50+ Silk Square Scarf.

Common questions
What does the NHS say about night-time leg cramps?
It says they are common, usually harmless and only last a short time, and that most people have them at night or when resting. They can last from a few seconds to 10 minutes, and the muscle can feel sore for up to 24 hours.
What should I do during a cramp?
The NHS says stretching and massaging the muscle may ease the pain, although most cramps go away without you doing anything, and that standing up and putting weight on the leg may also help. Painkillers such as paracetamol or ibuprofen do not help while it is happening because they take too long to work.
Can calf stretches stop them?
The NHS says regular calf stretches may help reduce cramps but may not stop them completely. Its routine is to stand facing a wall, lean forward until the calves stretch, hold for 2 or 3 seconds and repeat for 5 minutes, 3 times a day, the last time just before bed.
Does a long day on your feet cause cramps?
The NHS page lists strain on muscles during exercise, which can be worse in hot or humid weather, along with ageing, pregnancy, some medicines and not drinking enough fluids. It does not name standing or rain, and says the reason for some cramps is unknown.
When should I see a GP?
The NHS says to see a GP if cramps are disturbing your sleep, if you also have numbness or swelling in your legs, or if a cramp lasts longer than 10 minutes.
