# Why Does Weather Give Us Headaches and What Can Help ## Jak počasí ovlivňuje naši hlavu Mnoho li
Everyone knows it – a storm rolls in, the pressure changes, the wind shifts, and suddenly a dull headache arrives to ruin the entire day. This is neither coincidence nor hypersensitivity. Weather-induced headache is a well-documented phenomenon that affects millions of people worldwide, and science is beginning to understand it better. What actually happens in our bodies when atmospheric conditions change, and what can be done about it?
The answer is not as straightforward as it might seem. The human body is an extraordinarily sensitive system that constantly responds to its environment – including changes that are completely invisible to the naked eye. Atmospheric pressure, humidity, temperature, solar radiation and electrical charges in the air – all of these can influence how we feel. And in some people, this sensitivity manifests as headaches or even full-blown migraines.

What happens in the body when the weather changes
The key player in the whole process is atmospheric pressure. When a front approaches – whether warm or cold – air pressure changes, and fairly rapidly. Our body must respond to this change. Blood vessels in the brain dilate or constrict, blood flow to the meninges and surrounding tissues shifts, and this is precisely what can trigger pain. A study published in the specialist journal Cephalalgia showed that migraine patients exhibit significantly greater sensitivity to drops in barometric pressure, with the risk of an attack increasing by up to thirty percent during a rapid pressure drop.
Air humidity and temperature also play a role. Dry, hot air causes dehydration, which is itself one of the most common headache triggers. Conversely, cold and humid air can worsen tension in the muscles of the neck and nape, which then refers pain to the head. It is therefore no surprise that people suffer most frequently at the turn of the seasons, when the weather changes from day to day and the body has no time to adapt.
The influence of solar radiation and light is also noteworthy. Bright, intense light – particularly in summer when the sun shines low on the horizon, or when reflected off snow in winter – stimulates sensitive receptors in the eyes and can directly trigger a migraine attack. This phenomenon is so well described that neurologists refer to it as photophobia and consider it one of the diagnostic criteria for migraine.
Then there is a lesser-known but fascinating factor – air ionisation. Before a storm, positive ions accumulate in the atmosphere, which according to some research affects serotonin levels in the brain. Serotonin plays a key role in regulating pain and mood. When its levels fluctuate, this can lead to dilation of cerebral blood vessels and subsequent pain. Conversely, after a storm, when the air is rich in negative ions, many people feel refreshed and better – and this is not merely a perception.
Who is most at risk and why
Not everyone responds to weather changes in the same way. There are groups of people who are considerably more sensitive to meteorological fluctuations, and their experience of headaches is therefore more intense and more frequent. First and foremost, these are people who suffer from migraines – a chronic neurological condition affecting approximately fifteen percent of the population. Their nervous system is generally more sensitive to various stimuli, making weather changes one of many potential triggers for them.
Alongside migraine sufferers, people with low blood pressure are also vulnerable, as their blood vessels respond less effectively to external changes. Similarly affected are people with chronic cervical spine problems or tension-type headaches – for them, the physical tension caused by cold or damp is a direct route to an all-day headache. Interestingly, women are generally more sensitive to meteorological headache triggers than men, which is likely connected to hormonal fluctuations that themselves influence the pain threshold.
Consider a specific example: Jana, a forty-five-year-old teacher from Brno, has suffered from migraines since her twenties. For years she believed that stress or overwork was responsible for her attacks. It was only when she began keeping a headache diary that she discovered the vast majority of her attacks occurred one to two days before a significant weather change – particularly before a storm or during a transition from cold to warm weather. Keeping such a diary proved to be a key tool for understanding her own triggers and planning preventive measures.
As the world-renowned neurologist and author Oliver Sacks said: "The brain is not a passive recipient of sensations – it is an active interpreter that constantly seeks patterns and responds to them." And it is precisely this reactivity of the brain that explains why some people can "feel" an approaching storm before they see it in the sky.
How to defend against weather-induced headaches
We cannot change the weather, but we can change how we respond to it. Both preventively and in the moment when pain has already set in.
Hydration is the first and simplest step. Dehydration amplifies pain sensitivity and weakens the body's ability to regulate blood circulation. Adequate fluid intake – ideally plain water or herbal teas – helps keep blood vessels in good condition and reduces the risk of an attack. Experts from the American Academy of Neurology recommend regular hydration, sleep and physical activity as the foundation of migraine prevention.
Regularity in daily routine is equally important. The body does not tolerate chaos – irregular sleep, skipping meals or sudden lifestyle changes weaken its ability to cope with external fluctuations. If we add stress on top of this, which itself increases muscle tension and nervous system sensitivity, we have an almost guaranteed recipe for a headache.
Among natural approaches, magnesium is worth mentioning, as deficiency is very common in migraine sufferers. Magnesium is involved in regulating nerve conduction and muscle relaxation, and its regular intake – whether through a diet rich in nuts, seeds and green leafy vegetables, or in the form of a quality dietary supplement – can significantly reduce the frequency of attacks. Herbs such as lavender and lemon balm work similarly, having a calming effect on the nervous system.
Caring for the home environment can also help. A quality air humidifier, temperature regulation in the room, and reducing noise and light stimuli at the first signs of pain – these are all simple steps with a genuine effect. Some people swear by essential oils, particularly lavender or peppermint, which when applied to the temples or the back of the neck can relieve tension headaches.
For those who wish to go further, there is the option of monitoring meteorological apps specifically focused on forecasting "migraine weather." Apps such as Migraine Buddy or Weather & Migraine allow users to link personal pain records with current meteorological data and identify individual patterns. It is a smart way to prepare for difficult days and take preventive action in time – for instance by planning a quieter schedule, remembering to take medication, or engaging in relaxation techniques.
Relaxation techniques themselves – meditation, yoga, breathing exercises or progressive muscle relaxation – have a firm place in headache prevention. They reduce the baseline level of stress and tension in the body, thereby raising the threshold at which external triggers such as weather changes can provoke an attack. Regular practice, even if only ten minutes a day, proves over the long term to be one of the most effective non-pharmacological approaches.
Of course, in the case of severe or recurring headaches, consultation with a doctor or neurologist is always appropriate. Chronic headache can have various causes, and meteorological sensitivity is just one of them. Modern medicine offers a wide range of preventive and acute treatment options – from specific medications and botulinum toxin to neurostimulation – and an accurate diagnosis is the key to effective treatment.
It is interesting to note that interest in more natural approaches to healthcare has grown significantly in recent years. People are increasingly seeking solutions that do not rely solely on medication, but take into account overall lifestyle, nutrition, movement and mental wellbeing. And this is precisely where the topic of weather-induced headaches connects with the broader approach to a healthy and mindful way of life – because a body that we care for holistically is more resilient to all kinds of stress, including the atmospheric kind.
The weather cannot be controlled, but our approach to our own health can. And that is perhaps the most important message to take away from this entire subject.
