Many people believe rainy or stormy weather worsens joint pain, low air pressure triggers headaches, or temperature can influence an unborn child’s gender. These ideas, passed down through generations, have been studied worldwide. Some show partial evidence; others remain unproven or purely anecdotal.

In 2013, neurologists documented a striking case: a man claimed he could smell intense skunk-like odour mixed with onions before storms arrived. Researchers could not pinpoint the exact cause, but it raised fresh questions about whether subtle weather changes truly affect the body.

Experts note links between weather and health risks, including heart attacks, migraines, and even birth rates in certain studies. However, not all claims hold up equally under scrutiny.

Rain and Arthritis Pain: Coincidence or Fact?

Many insist damp, windy weather aggravates arthritis. A 2011 study on rheumatoid arthritis patients found no consistent weather-related pattern in symptoms. Researchers suggest this perception may stem from confirmation bias — people remember pain more when they expect weather to cause it.

Still, the idea cannot be dismissed completely. Some studies show partial connections, though lifestyle factors, clothing, or indoor/outdoor exposure often influence results.

Low Air Pressure and Headaches?

A Japanese study tracked 28 migraine patients for a year and found increased headache frequency when air pressure dropped. Another study noted higher sales of headache medicine during low-pressure periods.

Experts believe pressure changes may affect the vestibular system (which controls balance), potentially raising risks of dizziness and migraines.

Colder Weather and Heart Attack Risk?

Heart attack rates rise in winter. A Chinese study showed mortality from heart disease increased by up to 40% in winter compared to spring or summer. Cold weather raises blood pressure, which is considered a key factor.

Warmer Weather and More Boys?

Some research suggests warmer years in the Northern Hemisphere correlate with slightly higher male birth rates. After London’s severe 1952 smog, female births increased noticeably.

The exact mechanism is unclear. Some link temperature to hormonal balance; others see it as an evolutionary response. Experts caution the effect is minor and has no practical use in family planning.

Cosmic Storms and Health?

Studies from Lithuania found higher heart attack and stroke mortality during intense geomagnetic storms or cosmic ray activity. Another claimed people born during such events had shorter average lifespans (by about five years).

These findings are still inconclusive and require more research.

Weather undeniably influences daily life. But the precise link to complex bodily changes remains partly unclear. While some connections have partial support, many claims await stronger evidence.

So before blaming every rainstorm for arthritis pain or predicting a baby’s gender by temperature, remember: science has not yet spoken the final word.
