Summer Safety
This is for informational purposes only. For medical advice or diagnosis, please consult a professional. I will include a list of resources at the bottom.
It’s no secret that July typically brings the hottest weather of the year. With elevated temperatures, you also face the increased risk of heat related illness, such as heatstroke and heat exhaustion. Implementing immediate measures, like frequent water breaks, is essential to protect against heat stress. And if you take SSRIs for a mental health condition, the risk of heat related illness increases.

SSRIs (Selective Serotonin Reuptake Inhibitors) are the most widely prescribed class of antidepressant medications, primarily used to treat major depressive disorder, anxiety disorders, OCD, and PTSD. They work by increasing the availability of serotonin—a neurotransmitter that regulates mood and emotion—in the brain. SSRIs block the reabsorption (reuptake) of serotonin by the presynaptic nerve cells. By preventing the brain from immediately reabsorbing it, more serotonin remains in the synaptic space to bind with receptors, which helps improve mood and communication between brain cells. Some commonly prescribed SSRIs include Fluoxetine (Prozac), Sertraline (Zoloft), Escitalopram (Lexapro), Citalopram (Celexa), Paroxetine (Paxil), and Fluvoxamine (Luvox).
SSRIs can impair your body’s temperature regulation and disrupt thirst perception, significantly increasing your risk of heat exhaustion, dehydration, and heat stroke. They can also cause photosensitivity, making you more prone to sunburn. Here are some ways you can stay safe this summer, while keeping your mind happy and healthy:
- Manage your medication: Keep SSRIs in a cool, dry place out of direct sunlight, as high temperatures can degrade their effectiveness.
- Protect your skin: Because some SSRIs cause photosensitivity, apply an SPF 30+ sunscreen daily and wear protective, lightweight clothing.
- Avoid peak sun: Limit outdoor activities and exposure between 10:00 AM and 4:00 PM when UV rays and temperatures are highest.
- Preempt dehydration: Drink fluids regularly before you feel thirsty. Carry water with you, and take breaks in the shade or indoors where it is cooler.
- Watch for warning signs: Monitor for rapid heartbeat, dizziness, nausea, headache, or excessive/absent sweating. Seek medical attention immediately if you feel you are experiencing a dangerous, heat related emergency.
In addition to SSRIs, individuals taking antipsychotics are also at risk. Antipsychotics, which are used to treat conditions like schizophrenia and bipolar disorder, can also interfere with the body’s natural cooling system, reducing awareness of heat or thirst, and increase the risk of overheating. This means people taking them may find it harder to stay cool during a heatwave.
So, as the temperatures rise, so must our ability to recognize the symptoms of a heat crisis. Watch for warning signs, stay hydrated, and limit outdoor sun exposure. Be sure to speak to your physician or healthcare professional if you notice severe or persistent sweating, are feeling faint or confused, or are unusually hot, which could be signs of heat exhaustion or heat stroke.
Until next time, stay happy, healthy, cool, and safe! ~Sally~
