If you don’t like the heat, you can get out of the kitchen as they say, but we want you to stay in the kitchen AND get out of the heat! That may be easier said than done. We set a high temperature record in March. I no longer know when to plant my garden or prune anything. What I’m learning is that excessive heat is more than just annoying, it ages you!

Each year, the heat and humidity bother me more. That’s annoying, but a new study published in Science Advances suggests that it’s not just making me uncomfortable, fussy, and sluggish. It could be phenologically aging me. If that’s true, it’s probably physiologically aging me too. That sounds bad.
It’s a given that excessive heat creates the danger of heat stroke. We also know it can adversely affect heart problems and age your skin. I guess it stands to reason that longer numbers of days with temperatures exceeding 100° Fahrenheit would affect us in other ways. My body certainly tells me to get out of the heat!
A friend who lives closer to the equator experienced 60 consecutive days of temperatures over 110° last year. As she tells it, she would get up and do her outside work knowing that it would be too hot later in the day. Her plan was to then come in and do paperwork and volunteer hours after that.
Instead, once she finished the farm work, she found herself lying on the concrete floor for hours until the sun went down. She simply didn’t feel like moving. Trying to figure out if she was getting old, lazy, or old and lazy, she finally realized that the heat seemed to be aggravating her heart problems and affecting her blood pressure.
This year, she’s moving further north for a month to see if she feels better. If that works, next year she’ll expand her heat vacation to three months. I have a neighbor who leaves in June and returns in September. Seems they are onto something.
Here’s an excerpt from the study:
“For example, one-unit increase in heat days at the caution+ level is associated with a 1.15-year increase in PCPhenoAge acceleration over a 7-day window (95% CI = 0.63, 1.67); this means that 10% more heat days corresponds to a 0.115-year PCPhenoAge acceleration. This association remains significant over 30-day (B = 1.08, 95% CI = 0.53, 1.62), 60-day (B = 0.98, 95% CI = 0.40, 1.56), 1-year (B = 1.66, 95% CI = 0.56, 2.77), and 6-year (B = 1.87, 95% CI = 0.68, 3.06) windows. Comparable results are observed for heat days at the extreme caution+ level; for example, a one-unit increase in heat days over a 6-year period is associated with a 2.88-year increase in PCPhenoAge acceleration (95% CI = 1.28, 4.48).”
The bottom line is that people who experience more heat over the long-term age faster biologically than people who live in cooler environments.
I will add that quality of life decreases when the heat index is over 100°. Gardening may become exhausting. It’s harder to stay hydrated. And sitting on the porch visiting with neighbors sounds like sitting in an oven baking with potatoes.
Not all of us can move or go away for months at a time. We may have to alter our schedules to garden at first light, walk for exercise indoors, and grill in instead of out.
I’m sitting in a stuffy RV with wind gusting up to 49 mph outside. Humidity is 86%. The temperature is only 68 outside, but it’s way hotter in here and it’s only April 2. I am dreading August.
Now’s a good time to practice staying in the kitchen where there’s air conditioning. And if you don’t like the heat…I’m with you!
