Why Does Summer Feel So Much Hotter Than It Did 10 Years Ago?
Hint: It's not just the weather.
Have you caught yourself saying, "I don't remember summers feeling this hot"?
You're not imagining it…but the answer isn't as simple as rising temperatures.
While many regions are experiencing warmer summers due to climate change, another important factor is often overlooked: your hormones. As we age, especially throughout our late 30s, 40s, and beyond, hormonal changes can significantly affect how our bodies regulate temperature.
If you've suddenly become the person who's constantly turning down the thermostat, avoiding the afternoon sun, or waking up drenched in sweat, your hormones may be trying to tell you something.
Your Internal Thermostat Changes with Age
One of estrogen's many jobs is helping regulate the body's temperature control center, located in the hypothalamus.
As estrogen levels begin to fluctuate during perimenopause and eventually decline during menopause, that thermostat becomes more sensitive. Even a small increase in body temperature can trigger your brain to respond as if you're overheating.
The result?
Feeling excessively warm when everyone else is comfortable
Hot flashes
Night sweats
Increased sensitivity to summer heat
Flushed skin and sudden sweating
For many women, these symptoms begin years before menopause, often during their 40s or even their late 30s.
It's Not Just Estrogen
While estrogen gets much of the attention, other hormones also play an important role.
Progesterone
Progesterone naturally rises after ovulation and has a warming effect on the body. As progesterone production becomes less predictable during perimenopause, many women notice changes in how they tolerate heat throughout the month.
Thyroid Hormones
Your thyroid helps regulate metabolism and body temperature. When thyroid hormones are too high, you may feel unusually warm and sweat more than normal. Even subtle thyroid imbalances can contribute to heat intolerance.
Cortisol
Chronic stress can keep cortisol elevated, making it harder for your body to regulate temperature efficiently. Poor sleep and ongoing stress may also intensify hot flashes and night sweats.
Why It Seems to Happen Overnight
Many women say,
"Last summer I was fine. This year I can't stand being outside."
Hormonal changes don't always happen gradually. During perimenopause, hormone levels can fluctuate dramatically from month to month, making symptoms appear suddenly.
It's common to experience:
Increased sweating during exercise
Difficulty sleeping because you feel too warm
Feeling overheated in restaurants, meetings, or social events
Less tolerance for hot, humid weather than you've ever had before
Could Low Testosterone Play a Role?
When most people think of testosterone, they think of men, but women need testosterone too.
Healthy testosterone levels support:
Energy
Muscle mass
Mood
Motivation
Metabolic health
While low testosterone isn't considered a primary cause of hot flashes, it often occurs alongside declining estrogen during midlife and can contribute to fatigue, reduced exercise tolerance, and an overall feeling of not being yourself. Addressing hormone balance as a whole may help improve how you feel day to day.
