Summer heat & anxiety medications: What you need to know
As summer temperatures soar, it’s important to be aware of how hot weather can interact with your mental health medications—particularly if you’re managing anxiety. While most people know to drink more water or apply sunscreen when the heat hits, fewer realize that certain anxiety medications can actually make it harder for your body to cope with high temperatures.
How anxiety medications affect your body in the heat
Medications like benzodiazepines (e.g., Lorazepam, Diazepam) and some antidepressants— including SSRIs and SNRIs, which are often prescribed for anxiety—can interfere with your body’s natural ability to regulate heat. These medications may
• Reduce your body’s ability to sweat, limiting your natural cooling process
• Affect hydration, making you more vulnerable to dehydration
• Impair heat response, increasing your risk of heat exhaustion or even heat stroke
Additionally, some of these medications can make your skin more sensitive to sunlight, leaving you prone to sunburn or skin irritation even after brief sun exposure.
5 tips for managing heat while on anxiety medications
If you're taking medication for anxiety or other mental health conditions, be extra cautious during hot weather. Here are some practical tips to protect your health:
Hydrate frequently – Aim for water throughout the day, even if you’re not feeling thirsty
Use sun protection – Apply sunscreen regularly, and wear a hat and protective clothing
Limit sun exposure – Stay out of direct sunlight during peak hours (10 a.m to 4 p.m)
Find shade or AC – Take breaks in cooler areas when spending time outdoors
Watch for signs of heat-related illness:
• Dizziness
• Nausea
• Rapid pulse
• Confusion
If you experience these symptoms, get to a cool place, sip water, and seek medical attention if your condition doesn’t improve.
Check in with your provider
If you’re concerned about how your medications might be interacting with the summer heat, don’t hesitate to reach out to your health care provider. Together, you can make a plan that keeps you both mentally and physically safe.
