As the winter months approach, most of us are trying to find ways to stay warm. If you can’t get warm even when you’re all bundled up, it could be your medications. Understanding how medications affect cold tolerance is crucial for maintaining comfort and safety during cold weather.
Common Medications That Can Lower Cold Tolerance
- Beta-Blockers: Beta-blockers, like Toprol (metoprolol) and Coreg (carvedilol), are medications commonly prescribed for conditions like high blood pressure, heart disease, and anxiety. These drugs work by reducing the heart rate and lowering blood pressure. These drugs reduce blood circulation, which can make you feel colder than usual.
- Antidepressants: Certain antidepressants, such as selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants, can interfere with the body’s ability to regulate temperature. This can result in a lower tolerance for cold or hot weather. Patients taking these medications should carefully prepare for extreme hot or cold temperatures.
- Antipsychotic Medications: Antipsychotic drugs, like those used to treat schizophrenia or bipolar disorder, can impact temperature regulation, and make you more prone to feeling cold or hot.
- Decongestants: Over-the-counter decongestants, like Allegra (fexofenadine) and Zyrtec (cetirizine), can sometimes lead to vasoconstriction (narrowing of blood vessels). This constriction can reduce blood flow to the skin, making you feel colder.
- Weight Loss Medications: Medications designed to aid in weight loss, such as appetite suppressants or fat blockers, may affect metabolism and thermoregulation and make you more sensitive to cold temperatures. Medications like Ozempic (semaglutide) and Wegovy (semaglutide) can cause cold intolerance by lowering the amount you eat and affecting your metabolism. If you’ve lost weight, you also have less body fat to keep you warm.
Managing Cold Sensitivity While on Medications
If you’re taking medications that lower your cold tolerance, there are several strategies you can use to manage this side effect:
- Dress For the Weather: Wear layers of warm clothing, including hats, gloves, and scarves. Multiple layers help trap heat and keep your body warm.
- Stay Active: Activity generates body heat. A brisk walk or even just fidgeting can warm you up.
- Plan Your Day: Check weather conditions before an outing and plan accordingly. When possible, avoid prolonged exposure to extremely cold temperatures.
- Communicate with Your Healthcare Provider: If you experience severe cold sensitivity, tell your healthcare provider. They may consider adjusting your medication or providing additional guidance.
While some medications may leave you feeling chilly, you can manage cold intolerance and continue to enjoy a safe and comfortable winter season. Always consult with your healthcare provider before making any changes to your medication regimen or if you have concerns about cold sensitivity while on medication.
