Suddenly dry skin all over the body: causes and when to have it checked

In short

If your skin suddenly becomes dry all over the body in autumn, the reasons are usually external: dry heated air, cold, long hot showers, soap and shower gel. Less often, dry skin all over the body is a sign of an internal cause, such as an underactive thyroid, kidney disease, diabetes, a medicine or a deficiency. What you can do: for two weeks, shower briefly in lukewarm water, use soap sparingly and apply cream straight afterwards; don't overheat your rooms; and have it checked by a doctor if nothing improves, intense itching sets in or signs such as tiredness, feeling cold, thirst, weight change or a new medicine fit the picture.

The problem: when all your skin feels tight and flaky

A few weeks into the heating season, it is no longer just the face that feels tight after showering, but everything: shins and arms are rough, fine flakes lie on dark clothing, the back itches in the evening. This is very common. In skin examinations of 48,630 employees in Germany, 29.4 per cent had dry skin, more often with increasing age (Augustin et al. 2019a); beyond 60, almost everyone has it (DermNet: Dry skin). A position paper by German dermatologists estimates that more than ten million people in Germany are affected and also calls dry skin a key symptom of many skin, internal and neurological diseases (Augustin et al. 2019b).

That is exactly what makes the question difficult: usually it is the winter, sometimes there is more to it. The overview below helps with orientation. It does not replace a diagnosis; only a medical examination gives certainty.

Why it happens in autumn and winter

The external reasons come together in winter. Low humidity and cold weaken the skin's barrier function and make it more susceptible to friction and irritants (Engebretsen et al. 2016). Heated air, wind and direct heat from radiators or fires draw water out of the horny layer; frequent bathing, soaps, cleaning products and friction from rough clothing remove fat (DermNet: Dry skin). Hot water adds to this: in an experiment with 50 healthy volunteers, the skin lost more than twice as much water after hot water as before (Herrero-Fernandez et al. 2022). Anyone who showers longer and hotter in winter affects the whole body surface at once, which is why the dryness then seems to appear "suddenly" and everywhere.

Then there are habits that are rarely connected with the skin: sauna sessions, swimming pools, hard water after a move, wool clothing directly on the skin. What limescale does when you wash is explained in Hard water and dry skin: what limescale does when you wash, what dry indoor air does in Humidity and skin: what dry heated air does and what helps. Why skin gets drier over the years is covered in Dry skin in old age: causes, winter care and applying oil safely.

When internal causes may be behind it

The table below lists conditions in which dry skin or itching all over the body has been described. It is not a self-test. Many of these signs also have harmless reasons; only a doctor can clarify whether a condition is present.

Possible causeWhat may show on the skinOther clues
Underactive thyroid, often due to the autoimmune condition Hashimoto's diseasedry skin, dry hair or hair loss; itching probably comes from the dryness (Weisshaar et al. 2025)tiredness, feeling cold, weight gain, constipation, hoarse voice; develops slowly; diagnosed with a blood test (NHS: Underactive thyroid)
Diabetesdry skin up to scaly skin, especially on the shins and feet (Piérard et al. 2013)tiredness, peeing more than usual, constant thirst, losing weight without trying (NHS: Type 2 diabetes)
Chronic kidney diseasedry skin; very common on dialysis, often with itching on the back, legs and arms (Sommer et al. 2022)usually known; discuss itching with the care team
Liver diseaseitching rather than dryness, often all over the body, at first on the palms and soles, worse in the evening and at night (Weisshaar et al. 2025)yellowish skin or eyes need to be seen by a doctor promptly
Medicinesdry skin, for example with oral retinoids, water tablets (diuretics) and certain cancer medicines (DermNet: Dry skin)onset after a new or changed medicine; never stop on your own
Malnutrition, marked weight lossdry skin (DermNet: Dry skin)can only be clarified by examination, not with supplements on suspicion
Acquired ichthyosisfish-scale-like skin that first appears in adulthood; rare, but linked to thyroid deficiency, lymphoma, other tumours, sarcoidosis or HIV (DermNet: Dry skin)have it checked promptly
Sjögren's syndrome and other autoimmune diseasesin Sjögren's syndrome, itching is usually linked to dry skin (Weisshaar et al. 2025)dry eyes and dry mouth

The solution step by step

StepWhat you doWhy
Now: change how you showershort, lukewarm showers instead of long, hot baths; bathe less often; soap or shower gel only where needed, or a mild soap substitutethis is what the dermatology source advises for dry skin (DermNet: Dry skin); hot water increases water loss (Herrero-Fernandez et al. 2022)
Now: apply creampat dry and generously apply a rich care product to the still slightly damp skin, for example the Solid Body Butter - Beeswax & Aloe Vera or, for large areas, Almond Oil - puregenerous and frequent care, especially after bathing, is the basis (DermNet: Dry skin)
Every day: indoor airdon't overheat rooms, air them briefly but thoroughly; a humidifier can help if it is kept cleandry, cold air weakens the barrier (Engebretsen et al. 2016)
Every day: clothingsoft fabrics directly on the skin, wool on topfriction from rough clothing dries the skin out (DermNet: Dry skin)
After two weeks: take stockclearly better: carry on. Unchanged or itchy: make an appointment and take a list of the medicines from the last twelve monthsthe guideline on chronic itch specifically asks about new or changed medicines in this period (Weisshaar et al. 2025)

What helps – and what doesn't really

MeasureAssessment
Short, lukewarm showers, then creamwith external causes usually helps within one to two weeks
Ever richer creams, but still hot showersrather not; the cause remains
Drinking a lotpart of good health, but no substitute for care; what is known about it is in Dry skin despite drinking plenty? What water, diet and omega-3 really do
Vitamins or minerals on suspicionrather not; whether there is a deficiency is shown by a medical blood test
Body scrub against the flakesrather not on dry, itchy skin; it adds friction
Stopping a medicine because the skin is drynever on your own; talk to your doctor or pharmacist first
Putting up with itching for weeksrather not; from six weeks, itching is considered chronic and should be investigated (Weisshaar et al. 2025)

Common mistakes

  • Only changing the cream. As long as the shower stays hot and long, even the richest care will hardly be enough.
  • Fragranced shower gels and bath additives on the whole body every day. Cleansing removes fat; on arms, legs and back, water is usually enough.
  • Not mentioning accompanying signs. Tiredness, feeling cold, thirst or weight changes belong on the table at the appointment, even if they seem to have nothing to do with the skin.
  • Taking supplements on suspicion. Whether there is a deficiency can only be shown by an examination; supplements on suspicion do not replace it. More in Dry skin and vitamin deficiency: causes and what you can do.
  • Leaving out a medicine. Even if the dryness started with it: this is something to discuss with the doctor.

When to seek medical advice?

Have dry skin all over the body checked by your GP if

  • it has not clearly improved after about two weeks of lukewarm showers and daily care,
  • the skin itches for longer than six weeks, itches intensely at night or itches without a visible rash; according to the guideline, internal diseases, medicines or nerve conditions are then also possible (Weisshaar et al. 2025),
  • tiredness, feeling cold, weight gain, hair loss or a hoarse voice are added (NHS: Underactive thyroid),
  • you are constantly thirsty, need to pee often or lose weight without trying (NHS: Type 2 diabetes),
  • your skin or the whites of your eyes turn yellowish,
  • the skin has been dry since a new or changed medicine; don't stop it, talk to your doctor or pharmacist,
  • the skin newly looks like fish scales or cracks, turns red or weeps; dry skin can turn into eczema (DermNet: Dry skin),
  • you have kidney disease or are on dialysis and your skin itches; in a German study of 302 dialysis patients, only 40 per cent of those with dry skin sought medical help, although most treated it themselves (Sommer et al. 2022).

Promptly, within a few days, you should go if itching all over the body occurs mainly at night together with fever, night sweats, unintended weight loss or great tiredness; the guideline names this as a sign of more serious illness (Weisshaar et al. 2025).

At the practice it is about talking, examining the skin and, if needed, a blood test. The European guideline names as first steps, among others, a blood count, kidney and liver values, the thyroid value TSH, blood sugar and iron stores (Weisshaar et al. 2025); which values are needed is decided by the doctor. For children with dry, itchy skin all over the body, the paediatrician is the right place.

Frequently asked questions

Why is my skin suddenly dry all over my body?
Usually because of winter: dry heated air, cold and long, hot showers affect the whole body surface at once. If it doesn't improve within about two weeks with lukewarm showers and daily care, have it checked by a doctor.

Which deficiency can cause dry skin all over the body?
Malnutrition and marked weight loss can make the skin dry. A vitamin deficiency is rarely the reason in Germany, as our page on vitamin deficiency explains; whether there is one can only be shown by a medical blood test. Supplements on suspicion do not replace this.

Can the thyroid cause dry skin?
Yes. Dry skin and dry hair are among the common signs of an underactive thyroid, together with tiredness, feeling cold and weight gain. The most common cause is the autoimmune condition Hashimoto's disease. It is diagnosed with a blood test.

Which diseases cause dry skin?
Besides skin diseases such as atopic eczema, mainly an underactive thyroid, diabetes and chronic kidney disease. With liver disease, itching tends to be in the foreground. Less common are autoimmune diseases such as Sjögren's syndrome or acquired ichthyosis.

My skin itches all over. What should I do?
First care for the skin and shower in lukewarm water. If the itching lasts longer than six weeks, wakes you at night or there is no visible rash, have the cause checked by a doctor.

Does drinking more help?
Drinking enough is important, but it does not replace care from the outside. With dry skin from heated air and hot showers, changing your habits helps most.

Which blood values are checked for dry skin?
That is decided by the doctor. For longer-lasting itching, the European guideline names as first steps, among others, a blood count, kidney and liver values, TSH, blood sugar and ferritin.

My skin is flaking all over my body. Is that dangerous?
Fine flakes in winter are usually dry skin. If the skin newly looks like fish scales, is red, weeps or if fever and feeling unwell are added, it should be seen by a doctor.
