Why You May Have Uneven Body Temperatures on Each Side

Understanding Asymmetrical Body Temperature

Have you noticed that one side of your body feels warmer than the other? An asymmetrical or uneven body temperature is more common than you may realize. Keep reading to understand what causes temperature differences between sides of the body and when it may indicate an underlying condition.

What Is Considered a Normal Body Temperature?

Before exploring temperature asymmetry, it helps to understand average body temperature. A normal oral temperature is typically around 98.6F (37C). However, many factors like age, time of day, and activity level influence temperature within a healthy range of 97F (36.1C) to 99F (37.2C).

Your temperature is lowest in the early morning and increases by 1F to 2F throughout the day. Vigorous exercise can also raise your temperature up to 103F (39.4C) as your body works to cool itself.

Why Do We Have A Symmetrical Body Temperature?

Maintaining an even, balanced body temperature on both sides is essential for overall health. When functioning properly, the hypothalamus region of the brain closely regulates temperature by signaling responses like:

• Constricting blood vessels to decrease heat loss
• Stimulating shivering to generate body heat
• Releasing sweat for cooling

These mechanisms work to keep your measurable temperature within 0.5F (0.3C) between opposite sides of the body in most cases.

What Causes Uneven Body Temperatures?

While a 0.5 to 1F temperature asymmetry is harmless, more significant or persistent differences on one side may indicate an underlying issue. Potential causes include:

1. Inflammation and Infection

Inflammation from illness or injury can make the affected area feel much warmer than the surrounding tissue. For example, a bacterial skin infection on your arm might make it feel feverish compared to the other arm.

This happens because inflammatory responses in your body increase blood flow as infection-fighting white blood cells and other immune defenses are recruited to the region. The heightened blood flow to the inflamed area releases excess heat.

2. Circulation Problems

Issues with blood circulation can also hamper your body's ability to maintain an even temperature. Poor blood flow means oxygen and nutrients vital for metabolism and heat production don't reach the extremities as efficiently.

Medical conditions like peripheral artery disease, varicose veins, diabetes, and blood clots can all restrict blood flow. Nerve damage, injuries, smoking, obesity, and aging also contribute by harming circulation.

3. Skin or Nerve Damage

Since your skin and nerves work together to regulate body heat, damage to either system can disrupt optimal temperature control. Nerve damage or disorders mean critical signals about external temperatures don't reach the brain promptly.

Meanwhile, skin trauma from burns, wounds, or surgery can make it harder for the affected area to retain a steady temp. Scarring and loss of functioning sweat glands interfere with the skins role in trapping heat inside the body.

When to Seek Medical Care

In most cases, a slightly higher temperature on one side of your body isnt concerning on its own. However, if you notice any of the following, consult your healthcare provider:

Significant or Prolonged Difference

While a subtle temperature asymmetry under 1F is usually harmless, a more prominent or persistent variance between body sides may require evaluation. This is especially true if accompanied by other symptoms like pain, swelling, numbness/tingling, or changes in skin color.

Fever

A markedly elevated temperature on one side over 100.4F (38C) likely indicates an infection or inflammation demanding medical treatment. Skin redness or a rash may also be present.

Sudden Onset

Rapid development of a substantial temperature difference may signal a new health issue like a blood clot or nerve compression. Seek prompt emergency care if it arises alongside numbness/weakness or difficulty moving the limb.

Catching circulation troubles swiftly improves outcomes before permanent tissue damage sets in. Fast medical intervention also helps contain infections before they spread further throughout the body.

Staying Proactive About Body Temperature Changes

Carefully tracking your bodys temperature from day to day aids early detection of asymmetry and associated conditions. Consider regularly checking different spots like underarms, hands, feet, knees and hips for comparison.

Dont ignore or downplay unusual temperature variances, inflammation, numbness, or pain, especially if prolonged or worsening. Getting checked out quickly facilitates successful treatment and prevention of complications when required.

Stay alert about body temperature changes and respond appropriately by talking to your doctor. Catching and addressing problems early is vital for protecting your health and wellbeing.
