Medications That Can Cause You to Overheat Faster

How Medications Can Make You More Susceptible to Overheating in Hot Climates

Living in southern Louisiana, it’s hard to imagine the heat getting any worse, but if you’re taking certain medications, the high temperatures and humidity can take a greater toll on your body, making you more vulnerable to heat-related illnesses.

The hypothalamus, a part of the brain, helps regulate body temperature by controlling sweating and directing blood flow to the skin, arms, feet, and face to release heat. However, some medications can interfere with these processes, making it harder for your body to cool down and maintain a stable core temperature. Medications that may affect your ability to sweat or circulate blood effectively include:

• Antidepressants
• Antipsychotics
• Beta blockers
• Antihistamines and decongestants
• Amphetamines
• Diuretics

Many of these medications belong to a group known as anticholinergics, which work by blocking the neurotransmitter acetylcholine. Anticholinergics are used to treat conditions like COPD, gastrointestinal disorders, and Parkinson’s disease. Additionally, some medications, such as amphetamines used for ADHD, can directly increase body temperature. Others, like diuretics, can lead to dehydration, heightening the risk of heat-related illnesses.

Certain populations, like older adults, are particularly at risk because their bodies don’t adjust as easily to temperature fluctuations. Babies are also more vulnerable since they don’t sweat as much to cool down. Additionally, pregnant women face an increased challenge, as their bodies must work harder to regulate heat for both themselves and the baby.

Whether or not you’re currently taking any of these medications, there are several ways to reduce your risk of heat-related illnesses:

• Schedule outdoor activities during the early morning or after sunset, avoiding the peak midday heat.
• Stay hydrated by drinking plenty of water rather than sugary sports drinks.
• Wear the right gear, such as breathable clothing, sunscreen, and cooling accessories.
• Take frequent breaks in the shade, especially if you’re working outdoors.
• Pay attention to your body’s signals and get out of the heat if necessary.

By taking these precautions, you can stay safe and cool, even when temperatures soar.
