Spring Fatigue: Why You Lack Energy and What Actually Helps

Picture this morning. Outside the window, real sunshine is shining for the first time in months. The birds have been making a racket since dawn. The thermometer shows a pleasant double-digit temperature. Everything is shouting: "Wake up, live, get going!" And you're lying in bed feeling as if someone has drained all your batteries.

You get up with difficulty. At work you can't focus - your thoughts scatter in all directions. In the afternoon you feel like lying down on the floor and falling asleep. You're irritable for no reason. And then there's that runny nose that came out of nowhere.

Sound familiar? This is probably spring fatigue. And although the name sounds a bit like a folk excuse for laziness, there's concrete physiology behind this state. Today we'll explain what really happens in your body in spring - and what you can do to regain your energy. Without buying ten colourful boxes all at once.

What exactly is spring fatigue?

Spring fatigue is the common term for a set of symptoms that appear in many people at the turn of March and April - during the transition from winter to spring. It isn't an illness, and you won't find this diagnosis in any official medical classification. But it is a real, noticeable state of weakness.

Your body worked in "saving mode" throughout the winter. Little light, cold, short days - the body slowed down its metabolism, limited activity, adjusted its rhythm. In spring, conditions change abruptly, and the body needs time to "shift gears". This transitional period is precisely spring fatigue.

Typical symptoms of spring fatigue

Most people will recognise several of the following in themselves:

• Chronic tiredness - despite a full night's sleep, you wake up unrested
• Daytime drowsiness - especially in the afternoon, around 2 to 4 p.m.
• Decreased concentration - it's harder to focus on tasks, worse memory
• Irritability and mood swings - little things annoy you more than usual
• Headaches - dull, not very strong, but bothersome
• Decreased immunity - you catch infections more easily, the runny nose lingers longer
• Less motivation - "I don't feel like doing anything", even though objectively nothing bad is happening

Importantly - the symptoms of spring fatigue are mild and temporary. They usually resolve on their own within 2 to 4 weeks, once the body adjusts to spring. If they last longer or are severe, that's a signal to look for another cause - we'll return to this later.

Where does it come from? Four main causes

Spring fatigue isn't a single mechanism, but overlapping factors. It's worth understanding them, because that tells you where to look for solutions.

1. The aftermath of the winter shortage of light and vitamin D

This is probably the most important factor. Vitamin D is produced in the skin under the influence of solar radiation. In Central Europe, from October to March, the sun is too low above the horizon for the skin to produce it in sufficient quantities.

The result? In early spring, many of us enter the new season with a real vitamin D deficiency, accumulated over the whole winter. And vitamin D affects not only the bones - it is involved in the work of the immune system, the muscles, and also in mood regulation. Its deficiency is associated with fatigue, low mood and weakened immunity.

2. A poorer diet after winter

In winter we eat differently. Less fresh vegetables and fruit, more heavy, calorie-rich, processed dishes. After several months of eating like this, the body may have reduced reserves of certain vitamins and minerals - especially those whose main source is fresh plant products.

On top of this comes a common spring trap: an abrupt "cleansing of the body" with restrictive diets or fasting. This usually makes things worse - instead of adding energy, it takes even more of it away.

3. A disrupted circadian rhythm

Your internal clock - the circadian rhythm - is governed mainly by light. In spring the days lengthen rapidly, the sun rises earlier and earlier, and on top of this comes the change to summer time. The body has to readjust the production of melatonin (the sleep hormone) and cortisol (the alertness hormone).

This rebuilding doesn't happen overnight. For several weeks your biological clock may be "out of sync" - hence the difficulty falling asleep, the shallow sleep and the morning tiredness.

4. Fluctuations in weather and pressure

Spring weather is capricious - now warm, now cold, with abrupt changes in atmospheric pressure. People sensitive to these changes (weather-sensitive individuals) may then experience headaches, drowsiness, a feeling of being run down and dips in mood. This additionally overlaps with the other factors.

What actually helps - without buying ten products

Here's an important note at the outset. In pharmacies and drugstores, whole displays appear in spring "for spring fatigue" - energy complexes, adaptogens, multivitamins, "vitality tablets". The temptation to buy a set of five different products is strong.

But the truth is: most of the work against spring fatigue is done by lifestyle, not by tablets. Supplementation can be sensible support - but only support, and only in a few specific areas. Let's start with what works the strongest.

Light and movement in the fresh air

This is the cheapest and most effective "remedy" for spring fatigue. It works on two fronts at once - it provides light, which regulates the circadian rhythm, and movement, which stimulates circulation and improves mood.

• Go outside in the morning - even 15 to 20 minutes of morning light helps synchronise the biological clock
• Move every day - a walk, cycling, light jogging. It doesn't have to be intense, what matters is regularity
• Take breaks at work - a short walk outside in the middle of the day works better than another coffee

Sleep - a foundation, not a luxury

Since the circadian rhythm is out of sync, you have to help it stabilise. The most important principle is regularity.

• Go to bed and get up at fixed times - including at weekends
• In the evening, limit screens and bright, blue light - they interfere with the production of melatonin
• Make sure the bedroom is dark, cool and quiet
• Don't sleep off spring fatigue with long daytime naps - that throws the clock off even more

Diet - light, colourful, regular

Spring is a good moment to return to fresher food - but gradually, without drastic fasting.

• More vegetables and fruit - seasonal spring produce, a colourful plate every day
• Regular meals - a stable blood sugar level means stable energy
• Adequate hydration - dehydration in itself causes fatigue and headaches
• Careful with caffeine in the afternoon - it can make falling asleep in the evening harder and fuel a vicious circle

Sensible supplementation for spring fatigue

If lifestyle is the foundation, where is there room for supplements? Realistically, it's worth considering three areas - not ten. Remember, however, that dietary supplements are not medicines, and the decision to use them is best discussed with a doctor or pharmacist, especially if you take other medications.

Vitamin D

This is the most justified spring supplementation - because a real deficiency after winter affects a large part of the population. Guidelines recommend supplementing vitamin D in the autumn and winter months, and for many people also in early spring. The dose is best determined with a doctor, possibly after measuring the vitamin D level in the blood.

Magnesium

Magnesium is involved in the work of the muscles and the nervous system, and its deficiency is associated with fatigue, irritability and cramps. Some people experience improvement during spring fatigue after supplementing it. If you reach for magnesium, choose well-absorbed forms and don't exceed the recommended doses - an excess of magnesium most often leads to a laxative effect.

B-group vitamins

B-group vitamins take part in the body's energy metabolism and the work of the nervous system. With a poorer winter diet, supplementing them - preferably from a well-balanced diet, and if necessary from a preparation - can be sensible. Here too the rule applies: don't overdo the doses and don't buy five different preparations "to stock up".

The golden rule: if you're planning supplementation, it's better to buy one or two specific, sensibly chosen products than a whole "spring display". Less, but with sense - that works better for your health and for your wallet.

What to avoid with spring supplementation

Now that you know what to consider, it's also worth knowing what not to do. Spring fatigue is harvest time for the supplement industry, so it's easy to get carried away by marketing.

• Don't buy several products with the same ingredient - it's then easy to unknowingly exceed safe doses, because the same vitamins are often in a multivitamin, a separate preparation and an "energy" drink
• Don't treat a supplement as a substitute for sleep or movement - no tablet will make up for sleepless nights and a sedentary lifestyle
• Don't be guided solely by the promise on the packaging - slogans like "energy for the whole day" are the language of advertising, not a guarantee of effect
• Don't start several new products at once - when you introduce everything at the same time, you don't know what is actually helping and what is just straining the budget

A sensible spring support cabinet is usually a few well-thought-out items - not ten. Such a short, targeted set is also easy to compare on price afterwards and buy without overpaying.

A spring energy plan - how to structure your day

Knowing the causes and methods is one thing, and daily implementation is another. So instead of loose advice, see what a day can look like when structured to support the body during spring fatigue. Treat it as a draft to adapt to yourself.

Morning

The morning decides the whole day. The most important thing here is light and movement right after waking up.

• Get up at a fixed time - including at weekends, so as not to throw off the biological clock
• Let natural light into your eyes as soon as possible - open the window, and ideally step outside for a moment
• Eat a wholesome breakfast - this stabilises the energy level for the first half of the day
• Swap part of the morning coffee for a short walk - the invigorating effect tends to last longer

During the day

This is where the afternoon drop in energy usually hits. It can be eased with small decisions.

• Take short breaks for movement - a few minutes of walking resets the head better than another coffee
• Eat regularly - long gaps between meals deepen drowsiness and irritability
• Drink water systematically - dehydration in itself tires you and causes headaches
• Use your lunch break to go outside whenever the weather allows

In the evening

A good evening is the foundation of regeneration and a way to gradually stabilise the circadian rhythm.

• Limit intense, bright light and screens an hour before sleep
• Avoid caffeine in the afternoon - for many people it makes falling asleep harder and fuels a vicious circle
• Eat a light dinner - a heavy meal before sleep worsens its quality
• Go to bed at a fixed time, in a dark and cool bedroom

Such a rhythm won't work in a single day - but after two or three weeks of consistency, many people feel a clear improvement. This is usually more effective than any single supplement.

When it isn't "just" spring fatigue - warning signs

And here we come to the most important part of this article. Spring fatigue is mild and temporary. But identically - with tiredness, drowsiness, a drop in concentration - conditions can present that require diagnosis and treatment. The most common of these are anaemia and an underactive thyroid.

Anaemia

The most common is iron-deficiency anaemia. The body has no raw material to produce haemoglobin, which carries oxygen - hence the tiredness that doesn't resolve after rest. Symptoms that should draw attention:

• Paleness of the skin and mucous membranes
• Shortness of breath and heart palpitations on slight exertion
• Dizziness
• Brittle nails, hair loss
• Tiredness that persists for weeks and intensifies

An underactive thyroid

The thyroid governs the pace of metabolism. When it works too slowly, the whole body "slows down". The symptoms are sometimes confused with spring fatigue, but they are usually more persistent:

• Constant tiredness and drowsiness regardless of the season
• Weight gain despite an unchanged diet
• A feeling of constant cold, feeling chilly
• Dry skin, hair loss
• Constipation, low mood, sluggishness

What to do? If the tiredness lasts longer than 4 to 6 weeks, intensifies, is accompanied by the symptoms above or clearly hampers daily functioning - make an appointment with a doctor. Basic diagnostics are simple: a full blood count, measurement of iron and ferritin, and a test of the hormone TSH are usually enough to distinguish ordinary spring fatigue from a condition that requires treatment. Don't diagnose yourself on your own and don't "treat" a presumed anaemia with iron alone - an excess of it is also harmful.

Frequently asked questions

How long does spring fatigue last?

Usually 2 to 4 weeks - as long as the body needs to adjust to spring. If the symptoms persist longer than 6 weeks or intensify, it's worth looking for another cause and consulting a doctor.

Is spring fatigue the same as seasonal depression?

No. Spring fatigue is mild, temporary and does not seriously disrupt functioning. Seasonal depression is a mood disorder that requires the help of a specialist. If, besides tiredness, you experience persistent sadness, an inability to feel pleasure or thoughts of giving up - contact a doctor.

Does coffee help with spring tiredness?

In the short term, caffeine can add energy, but it doesn't solve the cause, and drunk in the afternoon it often worsens sleep and fuels the vicious circle of tiredness. It's better to rely on morning light, movement and regular sleep.

Do I have to supplement vitamin D in spring?

Many people have a real deficiency after winter, so supplementation is often justified in early spring too. The dose is best chosen with a doctor, possibly after measuring the vitamin D level in the blood - it's an individual decision.

Do "cleansing" fasts help with spring fatigue?

Usually not - restrictive diets and fasting most often deepen tiredness and irritability. A gradual change of diet to a lighter one, richer in vegetables and fruit, without drastic restrictions, works better.

Summary - what's worth remembering?

✅ Spring fatigue is a real, physiological state - not an excuse and not laziness.

✅ The main causes are the aftermath of the winter shortage of light and vitamin D, a poorer diet, a disrupted circadian rhythm and weather fluctuations.

✅ Lifestyle works the strongest - light and movement outdoors, regular sleep and a light, colourful diet.

✅ Supplementation makes sense only selectively - realistically it's worth considering vitamin D, magnesium and B-group vitamins, preferably after consulting a pharmacist.

✅ Less, but with sense - one or two sensibly chosen products instead of a whole pharmacy display.

✅ Vigilance is important - tiredness lasting more than 4 to 6 weeks may indicate anaemia or an underactive thyroid and requires a blood test.

✅ Don't diagnose yourself - a simple blood count, iron with ferritin and TSH will distinguish ordinary spring fatigue from a condition that requires treatment.
