Feeling overheated for no reason? From night sweats to hot flashes, temperature swings can be disruptive. Research suggests cannabis may play a role in helping the body maintain balance and support healthy thermoregulation.
We’ve all had that moment of being overwhelmed by a wave of heat with no clear reason. It usually passes and can be managed by removing a coat or sweater. But for some, that sensation of overheating is a regular, frustrating occurrence. Hormones, certain autoimmune conditions and even sleep disorders can all be the culprits behind temperature dysregulation, but whatever the cause, the situation is no less challenging.
But there’s good news: Whether you’re dealing with night sweats, navigating hot flashes in menopause or struggling to cool down after physical or emotional stress—cannabis may be able to help. In fact, a 2022 survey found that 33 percent of Canadian women aged 35–65 reported using cannabis within the last month, with many citing relief from menopause-related symptoms like hot flashes and sleep disruptions.
How Your Body Controls Temperature
Your body’s temperature regulation, or thermoregulation, is managed by the hypothalamus—the part of your brain that’s responsible for homeostasis, or your body’s ability to keep all of its processes in check. It works like a thermostat, responding to signals from your body and the environment. When it detects that you’re cold, it triggers shivering and reduces blood flow to conserve heat. When you’re hot, it prompts sweating and increased blood flow to the skin.
Hormones—especially oestrogen—play a big part in how the hypothalamus functions, which is why up to 80 percent of women experience hot flashes during perimenopause and menopause.
How Cannabis Factors In To Thermoregulaton
You probably already know that cannabis interacts with the endocannabinoid system, or the ECS, to influence mood, sleep, pain and more. It can also impact temperature regulation. Studies suggest that cannabinoids like THC and CBD affect neurotransmitters released by the hypothalamus. THC is known to cause a mild drop in core temperature, while CBD may help stabilize the nervous system—useful when stress is the driver behind heat surges.
Reliefs for Hot Flashes, Night Sweats and More
While research is still emerging, many people report that balanced or CBD-dominant strains or products can help reduce the intensity or frequency of heat events. Edibles taken before bed have been shown to improve sleep and ease night sweats. A recent U.S. study also found that midlife women using cannabis for menopause symptoms reported better sleep quality compared to those using hormone therapy alone.
Cannabis and Thermoregulation Beyond Menopause
Temperature swings aren’t limited to menopause. People with autoimmune conditions like multiple sclerosis, as well as those dealing with chronic stress or sleep disorders, can also experience temperature dysregulation. Early research suggests cannabis may help in these cases by calming the nervous system and reducing inflammation—two factors that play a role in how our bodies manage heat.
As always, start low and slow, and consult a cannabis-informed healthcare provider before you explore how cannabis can help you keep your cool.
