Many people experience weather changes with headaches, weakness, nausea, blood pressure surges, and exacerbation of respiratory and joint symptoms. This is called "meteosensitivity." Recent data clarify: some people do have a physiological vulnerability to fluctuations in barometric pressure, temperature, humidity, and the electrical activity of thunderstorms (especially those with migraines, chronic pain, asthma, and cardiovascular disease). The weather's contribution is variable and often moderate, compounded by personal triggers (sleep, stress, medications, dehydration). [1]

Large digital studies have shown that people with chronic pain are more likely to experience a "pain day" in conditions of high humidity, low barometric pressure, and wind. This effect was captured in real life using smartphone diaries in the "Cloudy with a Chance of Pain" study (2,658 participants, 15 months of follow-up). This doesn't mean weather is the sole culprit; it's part of the puzzle. [2]

Temperature extremes are important for the cardiovascular system. Cold is associated with increased blood pressure and higher mortality from cardiovascular causes; heat is associated with the risk of heat stress, dehydration, and decompensation of chronic diseases (especially in the elderly). The World Health Organization recommends heat as the leading weather-related health threat. [3]

Finally, high-profile episodes such as the 2016 "thunderstorm asthma" in Melbourne (a surge in visits and deaths among pollen-sensitized individuals) demonstrate that weather events can trigger widespread symptoms in vulnerable groups. This is important to consider for people with hay fever and asthma. [4]

Terms: meteosensitivity and meteolability

Meteosensitivity is a recurring association between worsening well-being and specific weather factors in one person (e.g., drops in blood pressure → migraine attacks). This is not a diagnosis in international classifications, but a description of the phenomenon that helps develop preventative measures (weather tracker + symptom diary). [5]

Weather sensitivity is a broader concept: increased autonomic reactivity (autonomic nervous system, vascular tone) to external fluctuations. This explains why, in some people, background factors (anxiety, lack of sleep, dehydration, medications) exacerbate the response to weather. In the clinic, we look at the sum of the triggers, not the weather alone. [6]

Table 1. Terms - short and to the point

Concept What is this Why is it necessary?
Meteosensitivity Repeated connection between weather and symptoms Customize prevention for your triggers
Meteorological instability Increased reactivity of the autonomous system Work with sleep, stress, hydration
Weather triggers Pressure, temperature, humidity, thunderstorms, wind Monitor and prevent exacerbations

Mechanisms: How weather triggers symptoms

Blood Pressure and Migraines. Drops and fluctuations in barometric pressure trigger cascades in the trigeminal vascular system in some people: vascular tone changes, sensory fibers are activated, neuroinflammation increases, and migraines develop. Reviews from 2023 to 2025 confirm the role of fluctuations in pressure and high humidity as triggers in a subgroup of patients. [7]

Temperature and the cardiovascular system. Cold causes peripheral vasoconstriction and an increase in blood pressure; heat causes vasodilation, fluid and electrolyte loss, and an increase in heart rate. Population-level studies show an inverse relationship between temperature and pressure, with an increase in cardiovascular events at extremes. [8]

Thunderstorms, pollen, and bronchi. During thunderstorms, large pollen grains break into microparticles, the wind "drives" them into the ground layer, and sensitized people experience "thunderstorm asthma"—an acute bronchospasm that affects thousands at once. This is a rare but crucially important phenomenon for allergy sufferers. [9]

Humidity, wind, and chronic pain. High humidity and strong winds are correlated with increased pain in people with arthritis and fibromyalgia (based on smartphone cohorts). The mechanisms range from changes in tissue pressure to central sensitization; the effect is not universal and is moderate in strength, but it can be taken into account in personal planning. [10]

Table 2. Weather factor → probable mechanism → typical symptoms

Factor Mechanism Symptoms are more common
Pressure drop Shifts in tone, trigeminal activation Migraine, headache
Cold Vasospasm, increased pressure Increased blood pressure, joint pain
Heat Dehydration, tachycardia, electrolyte shifts Weakness, dizziness, exacerbation of cardiovascular disease
Thunderstorm + pollen Pollen fragmentation, aerosolization Bronchospasm in allergy sufferers
Humidity/wind Tissue pressure, sensitization Increased chronic pain [11]

Who is at risk and how common is it?

Migraine. Up to 15-20% of people experience migraines; for a significant proportion of these, weather is a trigger (according to diaries, 20% to 50% note a connection). Observational studies from 2023 to 2025 confirm the contribution of low pressure, high humidity, and heat to attack frequency in subgroups. [12]

Cardiovascular disease and the elderly. In population studies, cold has a stronger impact on mortality than heat, but extreme heat episodes also significantly increase risk, especially in older people, those with diabetes, and those with hypertension. [13]

Allergy sufferers and asthmatics. During pollen peaks and thunderstorms, the risk of exacerbations increases; in Melbourne in 2016, thousands of calls were recorded in a matter of hours due to "thunderstorm asthma." It is important for people with hay fever and bronchial asthma to heed warnings. [14]

People with chronic pain (arthritis, fibromyalgia, neuropathy). The relationship with weather varies from person to person, but on average, humidity, low pressure, and wind increase pain. The value lies in personal tracking and adapting your regimen. [15]

Table 3. Risks by group - what to monitor first

Group Main triggers What to keep under control
Migraine Drop in pressure, humidity, heat Sleep, Hydration, Magnesium/Caffeine, Quiet Days
Elderly, CVD Cold/heat Home pressure, clothing layers, drinking regime
Asthma/hay fever Thunderstorms during pollen season Peak flow, action plan, antihistamines
Chronic pain Humidity, wind, low pressure Load, heat/cooling, pain diary

Symptoms and patterns

Vulnerable individuals more often complain of headaches, heaviness in the head, nausea, weakness, "failures" when standing up, increased heart rate, shortness of breath in allergy sufferers, and increased joint and muscle pain. Repetition is important: the same type of weather → similar symptoms. [16]

Migraines are often triggered by a combination of humidity, high blood pressure, and lack of sleep. Asthma is triggered by pollen and thunderstorms. Orthostatic episodes are triggered by heat and dehydration. The more accurately you understand your own pattern, the easier it is to prevent an episode. [17]

In the elderly and with polypharmacy (multiple medications), heat can cause dizziness, confusion, falls - this is a red flag for immediate adjustment of fluids, clothing, and cooling of the room. [18]

When to see a doctor

Immediately - if you experience a severe headache "like a hammer blow," weakness in an arm or leg, slurred speech, shortness of breath with a blue tint to the lips, confusion in the heat, or loss of consciousness. This could indicate a stroke, heart attack, heatstroke, or severe bronchospasm. [19]

In the near future - if your blood pressure has started to fluctuate due to weather changes, your migraines have become more frequent, you have wheezing/coughing due to pollen, or you have chronic pain that significantly impacts your daily life - you need a management plan. [20]

Table 4. "Red flags" for weather sensitivity

Symptom Possible threat
Confusion + heat, dry, hot skin Heat stroke (emergency)
Sudden weakness of half the body, speech Stroke (emergency)
Shortness of breath with wheezing during thunderstorms/pollen Bronchospasm (urgent)
Blood pressure >180/110 mmHg + symptoms Hypertensive crisis (urgent)

Diagnostics: A Popular Science "Step-by-Step" Approach

Step 1: Journal. For 4-6 weeks, record symptoms (headache, pain, shortness of breath, blood pressure, heart rate), sleep, caffeine/alcohol, medications, and weather parameters (pressure, temperature, humidity, thunderstorms). This will help you see personal relationships rather than average ones. [21]

Step 2. Basic examination. Blood pressure measurements while lying down and standing (at the 1st and 3rd minutes), pulse, oxygen saturation during dyspnea, lung auscultation, and neurological assessment in people with headache complaints. Peak flowmetry is used for asthma. [22]

Step 3. Targeted tests.

  • For migraine: clinical criteria, the need for imaging is decided by the physician based on “red flags”.
  • For hypertension: home monitoring in cold/hot weather with adjustment of therapy.
  • For asthma/hay fever: allergy tests, spirometry, action plan. [23]

Step 4. Joint planning. Based on the diary and examination, the doctor helps create a personal "weather protocol": when to increase water and salt intake, when to reduce exercise, when to begin migraine prevention or strengthen anti-allergy protection. [24]

Table 5. Mini-algorithm: what to do if you suspect a weather problem

Scenario Act One Next
Drop in blood pressure, migraine is on the horizon Sleep + water, magnesium/caffeine (individually), dark room "Early" analgesic/triptan as planned
Cold, blood pressure rises Layers of clothing, warm hands/feet, home blood pressure monitoring Adjusting therapy with a doctor
Heat, weakness/dizziness Cooling, water with electrolytes, rest Check medications, plan for heat
Thunderstorm during pollen season, wheezing House/windows are closed, rescue inhaler Service Alerts, Asthma Plan

What Really Helps: Evidence-Based Methods

The basic strategy is to manage the triggers that increase the response to weather: sleep, hydration, nutrition, physical activity, stress, medications. This reduces the "amplitude" of the response and makes the weather more predictable. [25]

Sleep and routine. Lack of sleep increases the likelihood of migraines and increases autonomic instability. Try to go to bed and wake up at the same time, limit screen time 60 minutes before bed, and avoid alcohol on days before "weather" days. These are simple but effective measures. [26]

Hydration and electrolytes. In hot weather, increase fluid intake and supplement with electrolytes if you sweat or exercise. This is especially important for the elderly and people on diuretics. During orthostatic episodes (with the advice of a doctor), compression stockings and a moderate increase in salt intake are sometimes helpful. [27]

Thermal management. In cold weather, wear layers of clothing, warm socks and gloves, and heat your bedroom. In hot weather, seek shade, use the air conditioner on recirculation mode, use "cooling stations" (a damp cloth on the neck, a cool shower), and plan your morning and evening activities. The World Health Organization emphasizes that heat stress is the leading weather-related health threat. [28]

Migraine plan. Keep a diary, keep a "speed dial" (take your medication early when an attack is imminent), and consider preventative treatment if you have frequent attacks (as prescribed). Some patients find moderate caffeine and magnesium helpful—this varies from person to person. Weather forecasts ("migraine forecasts") can be helpful, but are not a substitute for a treatment plan. [29]

Allergy sufferers and asthma. During pollen season, follow warnings about the risk of thunderstorm asthma, keep your inhaler and antihistamine handy, close windows during thunderstorms, and use the air conditioner in recirculation mode. If episodes are frequent, discuss intensifying your basic therapy with your doctor in advance. [30]

Blood pressure and heart. In cold weather, monitor your blood pressure at home and don't hesitate to adjust your treatment with your doctor (sometimes winter/summer doses differ). In hot weather, discuss medications that increase the risk of overheating or dehydration (some antihypertensives, diuretics, and some psychotropic medications). [31]

Chronic pain. Plan "soft" activities on "weather-friendly" days: stretching, warm showers, short breaks. According to smartphone cohorts, humidity and low pressure exacerbate pain, so lighten your schedule in advance and reschedule strenuous activities for milder weather. [32]

Skepticism about "miracle cures." There's no evidence that weather-control bracelets, extreme detoxes, or "magnetic stickers" reduce weather sensitivity. The usual things work: a regimen, water, a medication plan, proper protection from heat and cold, and targeted treatment of your ailments. [33]

Table 6. What to do in different weather scenarios (quick reminder)

Scenario In 24 hours On the day of the "peak" After
A sharp drop in pressure (migraine) Sleep, water, limit screen time Early drug, silence/darkness Sleep restoration
Cold wave (pressure↑) Warm clothing, indoor activity Monitor your blood pressure at home and avoid hypothermia. Correction of therapy (if necessary)
Heat/humidity Morning to-do list, electrolytes Cooling, shade/air conditioning Water, rest
Thunderstorm + pollen Check your asthma plan House, windows closed, inhaler Return to normal mode

Prevention for every day

Personal "weather matrix." Identify 2-3 key triggers and write a short plan: "If X → do Y." For example: "If humidity is >80% and a front is approaching, take a triptan and cancel evening exercise." [34]

Prepare for the heat. Check your air conditioner and blinds, keep electrolyte solutions in the house, and plan a "cool spot" (such as a shopping mall or library). Health organizations are emphasizing heat wave preparation. [35]

Prepare for cold weather. Layers of clothing, shoes with non-slip soles, mittens, regular walking indoors, home blood pressure monitoring. [36]

Allergy season. Monitor pollen counts, develop an action plan, and discuss immunotherapy with an allergist if symptoms persist annually. [37]

Weeks Target Actions
1 Understand your profile Symptom + Weather Diary; Migraine/Asthma Basic Plan
2 Regime and water Sleep +20 minutes; labeled water bottle; electrolytes in hot weather
3 Home and work Air conditioning/heating adjustments; postponing heavy tasks from "weather" days
4 "Anxious suitcase" First-line medications, list of actions "if there is a front/heat/thunderstorm"

Myths and facts

"Weather harms everyone equally."
No. There are individual vulnerabilities (migraines, asthma, cardiovascular diseases), and for most people, the impact of weather is moderate and manageable. [38]

"It's suggestion."
Large-scale digital cohort data did show statistical associations (humidity, pressure, wind) with pain in patients. But the effect isn't universal and not always effective. A diary helps identify your pattern. [39]

"If you're hot, you should stop taking your medication."
This is dangerous. Some medications do increase the risk of overheating/dehydration, but only adjust your medication with a doctor. [40]

FAQ: Briefly about the main points

Is it possible to "cure" weather sensitivity?
Eliminate it completely – no, but significantly reduce its symptoms – yes: regimen, water, medication plan, temperature management, early treatment of migraines/asthma. [41]

Is there any point in "migraine prognosticators"?
As a reminder and a reason to rest/drink water in advance – yes. As a substitute for treatment – no. [42]

How can you tell if the weather is truly to blame?
Keep a diary for 4-6 weeks and compare your symptoms with weather parameters. If you see a recurrence, adjust your weather plan. [43]

Which is more dangerous: heat or cold?
At the population level, cold often leads to more cardiovascular outcomes, but heat is the leading weather-related cause of acute emergency conditions and service overload. We need to prepare for both. [44]
