Researchers have found that temperature, humidity, barometric pressure, and even rainfall patterns play a crucial role in our physical and mental health. In this post, we’ll explore some of the most common weather-health connections and discuss how we can use weather data to predict and mitigate health risks.
Weather and Your Health
Have you ever felt a headache coming on just before a storm? Or noticed your joints aching when the weather turns cold? Many people intuitively sense that weather affects their health, but the science behind these connections is often overlooked.
Common Weather-Health Questions Answered
Why Does the Weather Give Me a Headache?
Many migraine sufferers report that shifts in weather can trigger attacks, especially changes in barometric pressure. A drop in pressure—often preceding storms—can cause blood vessels in the brain to expand, leading to pain. Studies suggest that high humidity and sudden temperature swings can also trigger headaches.
Does Cold Weather Really Make Joint Pain Worse?
People with arthritis frequently claim their pain worsens in cold or damp conditions. While the exact mechanism isn’t fully understood, research suggests that drops in barometric pressure can cause tissues to expand, leading to increased pain in sensitive joints. Cold weather may also reduce blood circulation, making muscles and joints stiffer.
Can You Actually Catch a Cold from Cold Weather?
Cold temperatures don’t directly cause colds, but they create conditions that help viruses spread. Research has shown that low humidity allows flu viruses to remain airborne longer, increasing transmission rates. Additionally, cold air dries out nasal passages, making it easier for viruses to enter the body.
How Does Weather Affect Mental Health?
The connection between weather and mental health is well-documented. Seasonal Affective Disorder (SAD), a type of depression that occurs in the winter months, is linked to reduced sunlight exposure, which disrupts melatonin and serotonin levels. Extreme weather events like floods and heat waves have also been shown to increase anxiety, depression, and PTSD.
People who live far from the equator, where sunlight hours drastically decrease in the winter, are more likely to experience SAD. Additionally, if you have a family history of depression or other mood disorders, you may be at a higher risk. -- Stephanie Strouth, LPC & Owner at Anchoring Hope Counseling
Medical Geography: Mapping Weather’s Role in Health
Medical geography is the study of how location and climate influence health outcomes. By mapping disease patterns, scientists can predict outbreaks and understand how climate change is altering health risks.
Disease Spread & Climate Change
Influenza & COVID-19 – Research shows that flu viruses thrive in low-humidity environments, while COVID-19 transmission rates were affected by temperature and humidity levels.
Valley Fever – This fungal disease is more common in dry, dusty climates like the southwestern U.S., where soil disturbance can release infectious spores.
Mosquito-Borne Illnesses – Warmer temperatures and increased rainfall expand mosquito habitats, increasing the risk of diseases like malaria and West Nile virus.
Air Quality & Respiratory Health
High humidity can make air feel heavier, worsening asthma symptoms.
Dry air can irritate airways, making people more susceptible to respiratory infections.
Wildfire smoke and pollution worsen lung diseases like COPD and asthma.
Seasonal Depression & Sunlight Exposure
Regions with long winters and limited sunlight see higher rates of Seasonal Affective Disorder (SAD). Lack of sunlight reduces vitamin D levels, which affects serotonin production and can lead to depression.
Turning Weather into Impact: Predictive Health Insights
With advances in meteorology and health analytics, we can now use weather forecasts to predict and mitigate health risks.
At the start of the COVID pandemic, Adiabat utilized early research studies published around COVID-19 spread to develop a weather-centric COVID spread forecast. The model was rooted in relationships between known virus spread and weather variables like temperature, wind speed, and humidity.
Here are additional ways to turn weather information into actionable insights for health and well-being:
Migraine Days
Some health platforms now include "migraine risk" forecasts, helping headache sufferers prepare by staying hydrated and avoiding triggers.
High-Spread Forecasts
Flu season forecasts use humidity, temperature, and case data to predict when flu transmission will spike. Schools, workplaces, and hospitals can use these alerts to reinforce hygiene measures.
Public Health Alerts
Governments issue heat advisories to prevent heatstroke and air quality warnings to protect vulnerable populations. Cities can implement cooling centers or limit outdoor activities during dangerous conditions.
Weather and Your Health: One Piece of a Bigger Puzzle
Weather isn’t just about what to wear—it can play a direct role in your health. Weather is just one of many influencing factors. Close contact with others, genetics, personal hygiene, air quality, access to healthcare, and lifestyle choices all significantly impact well-being.
