hot always

If you’re constantly turning down the thermostat or parking yourself in front of a fan, you may wonder if your internal thermometer is broken.

Or, you may assume that you’re on the inevitable path to menopause. Feeling toasty isn’t an automatic sign that you’re barreling toward the end of your menstrual cycle.

“There are so many other reasons why a person has hot flashes that has nothing to do with menopause,” says Shraddha Shah, MD, a family medicine doctor at Placentia-Linda Hospital in Placentia, California.

But take note of your symptoms—especially if you’re sweating buckets or experience weight change, fatigue, or a racing heart beat—and check in with your doctor to help you figure out what’s going on.

Here are 10 common reasons why you feel hot all that time.

If you’re sweating all the time (especially at night) or can’t stand the heat, it may be a sign of insulin resistance.

This means your body has a hard time keeping blood sugar levels in check.

“Sweat and the sensation of heat intolerance is more common in those who are prediabetic or insulin resistant” and is a common cause of hot flashes among patients, says Rebecca Booth, MD, a board-certified obstetrician and gynecologist based in Louisville, Kentucky and an expert in hormonal wellness. Booth says blood sugar fluctuations may trigger the body’s fight-or-flight response, causing your temperature to rise and fall.

If you always run hot, one likely culprit may be your thyroid, the butterfly-shaped gland in your neck.

An overactive thyroid pumps out too much thyroid hormone, revving up your metabolism and making you feel overheated, according Dr. But an under-active thyroid can have a similar effect, too.

Weight change, fatigue and heart palpitations are other signs of a malfunctioning thyroid. Feeling overburdened or overly anxious can lead to a case of the sweats.

“The rush of adrenaline can cause a feeling of warmth, which is easy to confuse with hot flashes,” says Dr. Try deep breathing exercises or take a walk to calm your nerves and cool off.
