Anyone who's 'always hot' issued warning - as it could be sign of serious condition

People who are 'always hot' have been issued a health warning, as while it could be nothing, it could also be a symptom of a serious condition.

We all know those people that refuse to turn the heating on and constantly want the windows open, even if the temperature is in the minus degrees outside.

They fall into the same category of those who don shorts all year round, even in December.

While you may tease or poke fun at these people, if you are feeling hot all of the time, it's worth getting checked out by a doctor to rule out anything serious.

First of all, it's important to note that it's completely normal to feel hot from time to time, especially if you're a person who has always generally been on the warmer side.

Various lifestyle and environmental factors can temporarily cause it, such as exercising, being outside in hot weather, or even drinking a hot caffeinated beverage.

Alcohol and spicy food are also likely culprits, according to Cleveland Clinic.

This is because the caffeine found in coffee, tea and fizzy drinks boosts heart rate and metabolism, which may make you feel hot.

As for booze, it causes increased sweating and blood flow to your skin, making you feel warm, and finally, spicy foods make your body think it’s warm, which activates the production of sweat to cool you down.

However, as we say, if none of these factors are behind it, there could be an underlying condition at play, such as hyperthyroidism.

Also known as an overactive thyroid, this health condition leads to heat intolerance and excessive sweating.

Other common symptoms include but aren't limited to nervousness, anxiety and irritability, hyperactivity, mood swings, difficulty sleeping, feeling tired all the time and muscle weakness.

As per the NHS, an overactive thyroid can sometimes lead to further problems, particularly if it's not treated or well controlled, so it's important to rule this out if you are feeling hot all the time and experiencing any of the other symptoms.

People who have diabetes, either type 1 or type 2, also feel the heat more than those of us who don't.

Dr Amy Bernstein told Cleveland Clinic: "A blood sugar level that’s too high or too low can make you feel hot and sweaty.

"This problem can occur if you have poorly managed diabetes. It can also be an early sign of the disease."

Meanwhile, another culprit behind why you're feeling hot and sweaty a lot could be fibromyalgia, which is a chronic disease that causes heightened sensitivity to pain.

Feeling hot and sweaty can be one symptom of the health condition, along with sleep issues, brain fog, headaches and fatigue.

Finally, in extreme cases some types of cancer can affect your hormone levels and make you feel hot - these are neuroendocrine tumours and pheochromocytomas.

As per Cleveland Clinic, neuroendocrine tumours occur in hormone-producing endocrine cells located throughout your body and some of them produce extra hormones that can lead to carcinoid syndrome, with the most common symptom of this being feeling flushed and warm.

Pheochromocytomas are tumours of the adrenal gland and they produce too much adrenaline, which can make you feel hot.

Of course, there are a whole slew of other reasons that could be behind it, including pregnancy, menopause, and even taking certain medications. But as we say, if you're unsure, it's always worth seeing a health professional.
