Why do we feel unwell when the weather changes?

**Why do we feel unwell when the weather changes?**

A headache before a thunderstorm, weakness in the heat, and sleepiness when the weather suddenly turns cold — many people associate these conditions with weather changes. But can atmospheric pressure and temperature really affect a person's well-being?

**What is weather sensitivity and why does it occur?**

Weather sensitivity is not a disease, but a general name for symptoms that a person associates with weather changes. While some people get a headache before rain, others experience fatigue, irritability, or sleep disturbances.

According to experts, the weather can be an additional load on the body. When temperature, humidity, and atmospheric pressure change, the body is forced to adapt to new conditions. Usually, this process goes unnoticed, but if there are certain chronic diseases or a lack of sleep, unpleasant sensations can intensify.

At the same time, not every deterioration in well-being is related to the weather. Behind simple weather sensitivity, migraines, sleep disorders, or other conditions requiring a doctor's examination can sometimes be hidden.

**How do heat and cold affect the body?**

In hot weather, skin blood vessels dilate, and the body begins to sweat more actively to cool itself. Along with sweat, fluid is also lost, which is why weakness, dizziness, and rapid heartbeat can be observed in the heat.

When the weather turns cold, the opposite process occurs: blood vessels constrict, helping to retain heat. Because of this, pulse and arterial blood pressure can change.

People with hypertension, heart disease, and other chronic illnesses should be especially attentive to their condition. High temperatures can increase the load on the cardiovascular system, and some medications can increase the body's sensitivity to heat.

**Why does the head ache before rain?**

In some people, weather changes can indeed trigger migraine attacks. Possible causes include changes in atmospheric pressure, high temperatures, and dehydration. However, what causes a headache in one person may not affect another at all.

Additional factors are also important. For example, if a person did not sleep well the night before, was stressed, or drank little water, the likelihood of feeling unwell increases.

The widespread belief that joints definitely ache before rain is not fully confirmed scientifically.

In 2024, researchers analyzed data from 11 studies involving more than 15,000 people. They found no reliable link between changes in temperature, humidity, atmospheric pressure, and knee or back pain. Gout is an exception: hot and dry weather can increase the risk of a disease flare-up.

**Why does fatigue occur when the weather changes?**

Sometimes, weather changes manifest not as a headache, but as a feeling of weakness. Even if it seems like you have rested enough, it becomes difficult to focus on work, and routine tasks require more strength.

A person's condition can be affected by hot weather, lack of fluids, and sleep disturbances. For example, it is harder to get enough sleep in a stuffy room, and after a sleepless night, fatigue is much more noticeable.

A deficiency of certain nutrients, including iron and B vitamins, can also be accompanied by weakness and decreased productivity. Therefore, it is incorrect to explain constant fatigue solely by the weather.

**How to ease your condition when the weather changes?**

It is impossible to completely eliminate the influence of external factors, but a few simple habits can help the body cope with temperature changes more easily.

**Maintain a sleep schedule**

Try to go to bed and wake up at approximately the same time. On hot days, keep a comfortable temperature in the bedroom as much as possible.

**Do not forget to drink water**

The need for fluids can increase due to sweating in the heat. If a doctor has recommended limiting fluid intake, follow their instructions.

**Engage in moderate physical activity**

Walking and other suitable exercises help maintain overall health. In extreme heat, it is better to do workouts in the morning or evening.

**Keep a health diary**

For a month or two, write down when unpleasant symptoms appeared, what the weather was like, how much you slept, and how you felt. This makes it easier to notice recurring patterns and discuss them with a doctor.

First of all, pay attention to the variety of your diet. It should contain sources of protein, iron, vitamins, and other essential nutrients. If a deficiency is suspected, supplements should be selected individually together with a doctor. For example, magnesium, vitamin B2, and coenzyme Q10 have been studied as migraine preventatives. Some studies show their potential benefits, but there is not yet enough evidence to recommend them to everyone with headaches.

You should not self-prescribe magnesium, omega-3, or other supplements just because you feel unwell before rain. They cannot replace the treatment of chronic diseases, and some of them can interact with medications.

**When to see a doctor?**

If headaches, weakness, or dizziness bother you regularly, you should not immediately attribute them to the weather. It is very important to seek medical help, especially if the symptoms appear for the first time, worsen, or interfere with daily life.

A sudden and unusually severe headache, chest pain, severe shortness of breath, fainting, or signs of a stroke require emergency medical attention.

The main thing to remember is that weather changes can affect a person's condition, but they should not remain a universal explanation for any unpleasant sensations. If the body regularly sends warning signals, it is better to find out their cause rather than trying to adapt to the next weather forecast.
