How does weather affect your health?
When atmospheric pressure decreases, your blood pressure drops, biometeorologist Jennifer Vanos, P.h.D., said in an interview with weather.com. Low temps cause your blood vessels to narrow, meaning on the whole, blood pressure is lower in the summer.
Self-harm has a season, according to biometeorologist Grady Dixon, P.h.D., who studies the weather and emotional health. Suicides spike in the late spring and early summer while overall, sour moods are more likely on cold, cloudy days.
Asthma and allergies
Changing seasons and hot weather can exacerbate asthma and allergy symptoms, with the growing season and air pollution playing a serious role. The fix? Be prepared with your allergy treatments before spring weather arrives.
Sudden changes in barometric pressure, such as the switch that occurs right before a storm, can trigger joint pain. Cold weather can also cause painful changes in joint fluid thickness, some research has found.
Headache and pressure
Barometric pressure can be a headache for some, though the reason is unclear. It might affect the pressure in the brain or the way the brain blocks pain, or it might be evolutionary, as it keeps humans in tune with their environment.
Headache and the seasons
As the days get longer, the additional exposure to bright light often triggers migraines. Pollen can also trigger headaches for people with allergies.
Blood-sugar changes and diabetes
Any front is associated with low pressure, so during cold fronts, blood viscosity, or thickness, increases, Vanos said. “Diabetics will have more trouble controlling their blood sugar during cold fronts,” she said.
When you’re out in the cold, your body’s “good” brown fat activates, which burns calories (the other type of fat, white fat, does not contribute to a calorie burn). Exercising when it’s hot doesn’t burn more calories, however.
Each 1.8 degree Fahrenheit the temperature drops is associated with around 200 additional heart attacks nationwide, according to a study in BMJ. Higher blood pressure, an increased risk of blood clots and challenging activities like shoveling show contribute to the risk.
COPD and other lung diseases
Hot, humid weather can make breathing difficult, particularly for people with preexisting lung conditions. Air pollution, which is worse when it’s hot, also plays a role.
Cold and flu
Many people swear they contract the common cold when the weather changes, Vanos said. Although it’s not entirely clear why, experts believe it’s because rapid temperature swings weaken your immune system. The cold virus also transmits better in cold air. Chinese medicine has long recognized environmental factors as a cause of illness. Factors include heat, cold, wind, and damp. There are specific treatments that help bolster the immune system and dispel the invasions.
People with ADHD are more likely to develop seasonal affective disorder, some studies have found. Plus, sunny regions are less likely to have a high number of ADHD patients.
When barometric pressure, or the weight of the air pressing down on the surface of the earth, changes, many people feel it acutely in their sinuses.
