Before summer, some people more often notice a runny nose, fatigue, a “general feeling of unwellness,” mild cold-like symptoms, or worsening of allergies. This may be related to seasonal infections, increased levels of allergens, and changes in environmental conditions. A short or mild episode on its own does not necessarily indicate a health problem, but if symptoms become frequent, prolonged, or overall condition worsens — it is worth paying attention.
In spring, the body often reacts to seasonal changes, temperature fluctuations, and exposure to new allergens. At the same time, respiratory viruses continue to circulate during this period, so symptoms may have different origins. In such cases, it is important to assess not only the presence of discomfort itself, but also its duration, frequency, and overall pattern.

Why you may get sick more often in spring
Body adaptation
The transition between seasons is a period when temperature, humidity, pollen levels, activity patterns, sleep, and even diet change. The body does not “break down,” but it does go through adaptation. Because of this, mild short-term symptoms may feel more noticeable than in winter or during more stable periods. This is more of a contextual explanation rather than a medical diagnosis.
External factors
In spring, pollen becomes an important trigger, and respiratory viruses do not suddenly disappear. The CDC notes that the common cold remains a very frequent infection, with adults experiencing on average 2–3 colds per year, and children even more. So not every runny nose in May is something unusual.
| What may affect | How it may manifest |
|---|---|
| Pollen and allergens | Runny nose, itching, watery eyes |
| Mild viral infections | Nasal congestion, weakness, sore throat |
| Changes in sleep and activity patterns | Fatigue, feeling drained |
| Weather fluctuations | Increased sensitivity of mucous membranes |
When this may be within the normal range
Mild symptoms
A short episode of a runny nose, a few days of fatigue, or a reaction to pollen can be a typical part of the seasonal transition. Especially if symptoms resolve on their own, do not significantly disrupt daily life, and do not keep recurring.
Short-term conditions
If symptoms are not long-lasting, without high fever, severe weakness, shortness of breath, or prolonged course, they often do not indicate anything serious. However, it is important to look not at a single day, but at the overall pattern over several weeks. This is clinical reasoning rather than dramatization.
How to distinguish a cold, allergy, and seasonal fatigue
In spring, symptoms may look similar even if their causes are different. A runny nose, fatigue, nasal congestion, or watery eyes may be linked either to viral infection, allergic reaction, or general seasonal fatigue of the body.
One key factor is the duration and nature of symptoms. For example, cold-like conditions usually last a few days and may be accompanied by fever, whereas allergic reactions often persist longer and depend on exposure to the allergen.
Seasonal fatigue, in turn, is more often manifested by general low energy without pronounced respiratory symptoms.
| Sign | Cold | Allergy | Seasonal fatigue |
|---|---|---|---|
| Temperature | Often elevated | Rare | None |
| Runny nose | Yes | Yes (often watery) | None |
| Itchy eyes | Rare | Common | None |
| Duration | 5–7 days | As long as allergen is present | Intermittent |
| General weakness | Moderate | Sometimes | Often |

When to pay attention
Frequent or prolonged symptoms
If episodes occur frequently, last for weeks, do not resolve, or become more severe each time, this no longer resembles simple “body adaptation.” Especially if accompanied by persistent cough, marked weakness, loss of appetite, or other new symptoms.
Worsening overall condition
Warning signs include high fever, shortness of breath, pronounced lethargy, recurrent infections with short intervals, noticeable weight loss, or prolonged recovery. At this point, it is better not to explain everything as “seasonal adjustment.”
| Sign | How to assess it |
|---|---|
| Symptoms last a few days and resolve | Often not concerning |
| Runny nose due to pollen | Possible allergic cause |
| Frequent long episodes of illness | Worth attention |
| Significant worsening of condition | Medical consultation needed |
Questions and answers
How many times a year is it normal to get sick?
On average, adults may experience 2–3 episodes of common colds per year. In children, this number is usually higher due to the characteristics of the immune system and more frequent social contacts.
Can frequent illness be related to a weakened immune system?
Frequent cold-like conditions may be associated with various factors, including lifestyle, stress levels, sleep, and seasonal changes. In cases of recurrent or prolonged symptoms, it is advisable to consult a doctor for overall assessment.
Is it normal to feel mild discomfort several times in spring?
Yes, this can happen because allergens, viral infections, and environmental changes overlap in spring.
Do children get sick more often than adults?
Yes, the CDC states that children experience more colds than adults.
When is it no longer considered normal?
When symptoms are frequent, prolonged, or accompanied by noticeable deterioration in condition.
Can allergies look like a “constant cold”?
Yes, especially in spring.
Conclusions
Before summer, overall well-being may fluctuate: occasional fatigue, runny nose, or mild cold-like symptoms may appear. In many cases, this is related to seasonal factors — changes in temperature, viral activity, or exposure to allergens — and does not necessarily indicate a health problem.
At the same time, it is important to pay attention to the frequency and duration of symptoms. If discomfort occurs often, lasts longer than usual, or noticeably affects daily well-being, it may be a sign that the body is reacting more sensitively to stressors or external factors.
In such cases, it is advisable to assess the overall condition and, if necessary, seek medical advice to clarify possible causes.
