Common Medications Raise Heat Risks
Common medications may raise heat-related health risks in extreme weather, experts warn. These drugs can affect sweating, thirst, blood flow, or body temperature. Therefore, people taking medicines should take extra care during heat waves.
Several medicines for depression, anxiety, and bipolar disorder may change temperature control. Some antidepressants can affect sweating, making it harder for the body to release excess heat.
Mental Health Medicines and Heat
Certain medicines can affect the hypothalamus, which helps control body temperature. As a result, some people may struggle to cool down during hot weather.
Stimulant medicines used for ADHD may increase heat production and narrow blood vessels. Some antipsychotic medicines can interfere with temperature regulation. Studies have linked some medicines with serious heat-related outcomes.
However, people should not stop prescribed treatment without medical advice. Instead, they should ask a doctor or pharmacist about the effects.
Blood Pressure and Heart Medicines
The risks also involve medicines for high blood pressure and heart conditions. Diuretics can change fluid and salt levels, while ACE inhibitors and ARBs may affect the body with dehydration.
Medicines can reduce thirst awareness. Therefore, people may not notice when they need more fluids. Severe dehydration can put extra strain on the kidneys and cardiovascular system.
Experts recommend staying hydrated and avoiding excessive heat when needed. People should watch for weakness, dizziness, confusion, or other concerning symptoms.
Stay Alert During Heat Waves
Medication effects may not always seem obvious. During a European heat wave, one woman reported severe tiredness while living without air conditioning.
Her apartment reached 34°C, and she struggled with extreme fatigue. She later questioned whether her antidepressant and anxiety medicines contributed to her symptoms.
Experts say people using medicines that affect temperature control should remain careful. Checking medication guidance before a heat wave can help people prepare safely.
