Why Heat Affects Medications
Summer is often seen as a time to slow down, recharge, and enjoy the outdoors. However, for many people, this season can also bring a unique kind of stress. Travel logistics, heat-related fatigue, disrupted routines, and the pressure to be constantly active can take a toll on both mental and physical well-being.
Instead of reaching for high-caffeine drinks or quick fixes that lead to burnout, many people are turning to evidence-based natural remedies that support calm, focus, and recovery, without sedating side effects or dependency. Here are four pharmacist-recommended options to consider this summer:
1. Magnesium Glycinate: The Nervous System Supporter
Magnesium plays a critical role in nervous system regulation, muscle relaxation, and sleep quality. Research shows that low magnesium levels are linked to increased anxiety and sleep disturbances, yet many Canadians are unknowingly deficient due to stress, poor diet, or medication use.
Why it works:
Magnesium glycinate is a well-absorbed form that’s gentle on the stomach and known for its calming effects.
Common uses:
- General anxiety
- Muscle tension
- Poor sleep
- Headaches caused by stress
Available in capsules or powder format, magnesium can be taken daily and is generally safe for most people, but consult your pharmacist if you take medications for blood pressure or heart conditions
2. L-Theanine: Calm Focus Without Fatigue
L-theanine is an amino acid naturally found in green tea, known to promote alpha brain waves; the same type associated with calm and alert states. It has been shown in studies to reduce physiological markers of stress, such as heart rate and cortisol levels, without causing drowsiness.
Why it’s helpful:
It helps support mental clarity during periods of stress or high demand, making it popular among students, professionals, and frequent travellers.
Ideal for:
- Daytime anxiety
- Exam or work stress
- Public speaking or social tension
It can be taken alone or alongside low doses of caffeine to reduce jitters
3. Ashwagandha: The Adaptogen for Burnout
Ashwagandha is a traditional herb used in Ayurvedic medicine, now backed by modern studies showing its effectiveness in reducing cortisol, the body’s primary stress hormone. It belongs to a group of herbs known as adaptogens, which help the body adapt to physical, emotional, and environmental stress.
Evidence shows:
Daily use of ashwagandha (particularly KSM-66 or Sensoril® extracts) can support:
- Reduced stress and anxiety
- Improved energy levels
- Better sleep quality
- Enhanced resilience during burnout
Ashwagandha is available in capsules, powders, and teas. However, it may interact with certain medications, including thyroid drugs, so speak to your pharmacist before use.
4. Melatonin (Used Properly): Resetting Your Internal Clock
While not a stress reliever in the traditional sense, melatonin can be a useful tool when stress affects sleep. Melatonin is a hormone that helps regulate your sleep-wake cycle, and short-term use can be helpful for:
- Travel-related jet lag
- Shift work
- Trouble falling asleep due to racing thoughts
A low dose (0.5–3 mg) taken 30–60 minutes before bed is typically enough. Overuse or high doses can cause grogginess and interfere with natural melatonin production, so it’s best used occasionally or with guidance.
