Weather and Your Mind

Do rainy days depress you? Does excessive heat make you angry? Do humid conditions make you feel lazy and lethargic?

Several studies and articles over the years have looked into the connections between weather and mental symptoms and states. The data, not surprisingly, shows that although there is not a definitive, rock-solid link between weather and mood there are some clear patterns that emerge.

One research paper (Baylis P, Obradovich N, Kryvasheyeu Y, Chen H, Coviello L, Moro E, et al. (2018) Weather impacts expressed sentiment. PLoS ONE 13(4): e0195750.  published earlier this year studied the effects of inclement weather on people’s posts in social media, namely Twitter and Facebook, between 2009-2016. While the authors point out that this type of data does have limitations, including the fact that social media can distort who the subjects are and the ways they express emotions, the data from this research does indicate a lowering of overall mood during periods of cloud cover, extreme heat or cold, precipitation, and high humidity.

Other recent articles have investigated similar ideas. An interesting article on the website PsychCentral, written by John Grohol, Psy.D. ( commented on a recent blog post that reviewed some research showing a small impact on mood from weather. Dr. Grohol cited quite a bit of contrary research, showing that weather actually does have significant affects on mood including studies which show the largest impacts on emotion come from sunshine, temperature and humidity. In fact, quite a few studies seem to show negative impacts from high heat and humidity, including an increase in lethargy, aggression and violence.

Another, more light-hearted example of weather-mood research was a study done in France from 2013 (Taylor & Francis. “Feeling flirty? Wait for the sun to shine.” ScienceDaily. ScienceDaily, 28 January 2013. which studies the effects of sunshine on flirting. A 20-year old male chronicled the success or failure he had of getting the phone numbers of young women he met on sunny days versus cloudy days and found more success (22%) on sunny days vs. cloudy ones (14%).

And yet another interesting article ( cites quite a few studies and reports showing all kinds of effects on mood and behavior from weather, including higher tipping on sunny days, greater contemplation and study on cloudy days, and increased verbal aggression in the heat.

Clearly, there seems to be something to the idea that people think, react and behave differently depending on the weather they experience. Obviously, those who have recently experienced a weather catastrophe are going to be affected by that situation.  And some people have a condition known as Seasonal Affective Disorder (SAD) where they literally go into depression during periods of low sunlight. While more research is needed, there is no reason to believe that people are not mentally affected by weather.

What can you do about this? I’ll take a look at some tips in an upcoming post.

Florence’s Floods

Hurricane Florence is nearing the coast of North Carolina, and should make landfall overnight. While Florence is far from the strongest storm we’ve seen in recent years, it nonetheless will bring many of the same risks that hurricanes bring – a massive storm surge along coastal areas, and strong winds over 100 mph are possible even inland. But the main threat from Florence will be catastrophic flooding.

Almost all of North Carolina will see at least 5 inches of rain from this storm. But, the eastern half of the state will most likely receive more than 10 inches, with many areas, particularly along the coast, seeing between 15 and 30 inches of rain! This is due to the expected slow nature of the movement of the storm, once it nears the coastline. The circulation is expected to meander southwest for a couple of days, before turning north.

Preparations for the storm should be finalized today, and anyone in flood-prone areas should be evacuating.

Florence and the Tropical Machine

The tropical Atlantic has moved into high gear this September with two current active hurricanes, and one tropical storm. The main story is Hurricane Florence, however, with a landfall in North Carolina late Thursday now looking likely. The track following landfall is still quite uncertain, with a good chance that the storm could linger over the Carolinas or Virginia for at least a day or two. This could bring catastrophic flooding to that area, along with whatever damage could come with wind and coastal storm surge.
