How to Manage Your Diabetes in Extreme Summer Heat  

Published

How weather can affect your blood sugar  

 

We often look forward to a change of seasons and warmer temperatures. But if you have diabetes, you may be especially sensitive to the hot weather of summer.

Extreme heat can affect your blood sugar control. If you use insulin or your blood sugars aren’t effectively controlled, you could be at higher risk during the summer months. Worsening blood sugar control is often the main concern, and depending on your level of activity, developing low blood sugars may also be a concern.

If you’ve had complications from diabetes that have damaged the nerves to sweat glands, you may be unable to sweat properly. This can become serious as outdoor temperatures rise, leading to heat exhaustion and heat stroke.

Extreme temperatures can also damage your medications and testing equipment, says Dr. Marwan Hamaty, endocrinologist at Cleveland Clinic, Ohio. “I always remind my patients to take precautions to protect themselves and their supplies during both winter and summer.”

He says it’s important to get a handle on your blood sugar control before you engage in summer fun. “If your blood sugars are mostly higher than 250 mg/dl, I recommend improving your blood sugar control before engaging in heavy physical activity — regardless of the climate and the temperature, as recommended by the American Diabetes Association.”

Dr. Hamaty also advises that the extreme heat of summer affects blood sugar levels. How the heat affects your levels depends on what you’ve eaten, whether you’re well-hydrated and your activity level.

If the heat and your activity make you sweat a lot, you may become dehydrated, leading to a rise in glucose levels. “If you become dehydrated, your blood glucose levels will rise. This can lead to frequent urination, which then leads to further dehydration and even higher blood sugar levels — a kind of vicious cycle,” he says.

Things can become even worse if the treatment includes insulin: “Dehydration reduces blood supply to your skin and, therefore, the ability of your body to absorb the insulin you’ve injected is reduced,” he says.

Most types of insulin can tolerate temperatures up to 93-95 degrees Fahrenheit. Exposing your supply to anything higher than this will make the medication quickly break down. Be careful and pay attention to any insulin you’re carrying with you in the heat.

While it’s fine to store insulin and glucagon in the refrigerator, hot temperatures (as well as freezing temperatures) will cause the medications to degrade, making them ineffective and unusable. High temperatures can have a negative effect on other medications and diabetes management supplies too. Don’t forget about the weather’s effect on things like test strips and monitoring devices. When the mercury begins to rise, these items can change in their effectiveness.

Physical activity usually causes blood sugar levels to decrease, reducing your need for insulin. The sudden addition of exercise may put you at an increased risk for low blood sugars.

Therefore, if you’re active in extreme heat, know that you’re at high risk for both low and high blood sugars. This means you should take extra precautions and monitor your sugar levels before exercising.

“I advise my patients to maintain warm skin and adjust insulin dosage prior to engaging in physical activity because insulin adjustment could vary significantly,” says Dr. Hamaty. “But don’t allow the heat to keep you indoors. It’s OK to participate in outdoor activities and enjoy all types of weather as long as you take a few precautions.”

Dr. Hamaty also suggests seeking input from your doctor regardless of the temperature before adding physical activity to your routine.

Follow these tips to help manage your diabetes while enjoying the outdoors:

  1. Drink plenty of water.Staying hydrated is important for everyone during physical activity, and it’s especially critical if you have diabetes.
  2. Avoid becoming dehydrated.Carry small bottles of water or low-calorie electrolyte-replenishing sports drinks in a backpack or on a belt while you’re hiking or playing sports.
  3. Adjust your insulin as needed.Ask your provider or diabetes educator how you should adjust your insulin (and sometimes eating extra carbohydrates) before exercising. Typically, your first few doctor’s visits focus on urgent issues, such as getting diabetes under control. Ask about how to adjust your insulin so you can prepare to be physically active.
  4. Test your blood sugar levels frequently.Since hot temperatures can cause blood sugar levels to fluctuate, it’s a good idea to test more often. That way, you can take appropriate and immediate action to keep your levels stable. You should continue frequent monitoring for several hours after you’re done with your workout or other activity. That’s because the effects of activities on blood sugars usually last for a longer period of time.
  5. Keep items to treat low blood sugar with you. This includes glucose tabs or glucose gel. If you’re at high risk for very low blood sugar (if you have frequent low blood sugar or had very low blood sugar previously), you should also have a glucagon kit available.
  6. Take some snacks with you.Some snacks can serve as a meal replacement while others help prevent low blood sugar. Discuss possible options with your dietitian.
  7. Protect your medication and supplies. Take proactive steps to protect your insulin, glucagon kit and other supplies before you head outdoors, regardless of the temperature. Consider a car cooler that plugs into a 12-volt car adapter to keep your supplies at the proper temperature. This will keep the temperature stable for some time. If you’re going away from your car for an extended period, you’ll need to take your supplies along with you. If you are on insulin pump, be sure to protect your insulin pump from high temperatures. Depending on the situation and how long your activity will be, you might simply need to monitor your glucose more often. In certain circumstances (if it’s extremely hot or you’re out for an extended amount of time) consider using a long-acting insulin temporarily along with meal insulin injection instead of an insulin pump.
  8. Avoid sunburn. You can get sunburned while skiing on the slopes or while hiking in the summer. Sunburn stresses your body and can raise blood sugar levels. Use a broad-spectrum sunscreen and wear protective eye gear.
  9. Finally, limit how much time you spend outside in extreme temperatures. “While I advise staying active during the peak winter or summer months, I also tell my patients to try to take advantage of outdoors activities when temperatures aren’t too extreme,” says Dr. Hamaty. By taking a few precautions, you can enjoy an active, healthy lifestyle in most any weather.

Turks and Caicos Islands Hospital Celebrates Patient Safety Awareness Month: “Team Up for Patient Safety”

Published

on

Turks and Caicos Islands – March 23, 2026 – In recognition of Patient Safety Awareness Week, observed March 8–14, 2026, the Turks and Caicos Islands Hospital, operated by InterHealth Canada Ltd., proudly joined healthcare partners worldwide in advancing this year’s theme, “Team Up for Patient Safety.” The 2026 campaign emphasized the critical role of teamwork and reinforced the importance of collaboration among patients, families, care teams, and leadership in creating safer healthcare environments.

While globally observed as a week-long initiative, the Turks and Caicos Islands Hospital extended its activities throughout the entire month of March, underscoring that patient safety requires sustained commitment, continuous learning, and shared accountability.

A Month of Learning, Engagement, and Collaboration

Throughout March, the hospital hosted a series of Continuing Professional Education (CPE) sessions aimed at strengthening competencies and reinforcing a culture of safety across all levels of care. These included:

  • Patient SafetyYour Role, empowering individuals to recognize and act on their impact on safety outcomes
  • Effective Communication Strategies, focusing on delivering safe care through structured, reliable communication
  • TeamSTEPPS – Reinforcement and Expansion, strengthening the use of evidence based teamwork tools to enhance care delivery

Grand Rounds sessions further supported clinical excellence and knowledge translation, featuring:

  • Rescue Ready 2025: Translating AHA PALS Updates into Practice
  • Colorectal Cancer Screening: A Roadmap for Caribbean Countries
  • Beyond the Algorithm: Applying the latest American heart Association BLS & ACLS Guidance in Emergency Practice

To promote engagement and learning in an interactive format, a Patient Safety Trivia Event was also hosted. The event featured five dynamic rounds covering patient safety principles, general knowledge, and a TCI knowledge lightning round, with prizes awarded to the top five participants. In addition, we welcomed Grade 4 students to our Hospital Teddy Bear Clinic, which served as an innovative extension of our patient safety efforts. This initiative allowed children to role-play as caregivers by bringing their teddy bears for “treatment,” helping them understand basic healthcare processes such as first aid, hand hygiene, communication, and safe care practices. By introducing these concepts early, the clinic not only reduces fear associated with healthcare settings but also promotes awareness of patient safety behaviours in a simple, memorable way.

Reaffirming a Shared Commitment

A defining moment of the month was the symbolic passing of the Patient Safety Baton, reinforcing the collective responsibility for safe care:

“Patient safety is not one person’s responsibility. It is a commitment we share across teams, departments, organizations, and nations; and it is upheld in partnership with every patient and family we serve.”

Advancing the 2026 Patient Safety Objectives

Aligned with the global theme, the hospital’s initiatives focused on four strategic priorities:

  • Promote Collaboration: Encouraging active participation from all members of the care team, including patients and families
  • Enhance Communication: Strengthening open dialogue to improve understanding of care plans and safety protocols
  • Recognize Achievements: Celebrating progress while identifying opportunities for continuous improvement
  • Engage Communities: Inspiring broader discussions on patient safety, equity, and quality in healthcare delivery

Acknowledgements

The Board of Directors and Executive Leadership of the Turks and Caicos Islands Hospital extend sincere appreciation to all who participated in the month’s activities and contributed to the success and sustainability of this important initiative.

Special thanks are extended to our dedicated healthcare teams for their unwavering commitment to delivering safe, high-quality care; our video and production team for effectively amplifying key messages; our valued healthcare partners for their collaboration and support; and the leadership of the Turks and Caicos Islands, including Her Excellency the Governor, Dileeni Daniel-Selvaratnam, the Honourable Premier, Charles Washington Misick and the Honourable Minister of Health, Kyle Knowles for their continued guidance and commitment to advancing patient safety nationally.

Building a Culture That Lasts

“Patient safety is not a solo effort, it is a collective commitment that defines the integrity of our healthcare system,” said Isha Honoré, Quality, Risk, Patient Safety and Management Lead at the Turks and Caicos Islands Hospital. “Our responsibility is to design and sustain environments where teams are supported, patients are heard, and risks are proactively managed. Through sustained engagement beyond this month, we are advancing a culture of high reliability, where safety is consistently delivered, measured, and continuously improved.”

Dr. Denise Braithwaite-Tennant, Chief Executive Officer of the Turks and Caicos Islands Hospital, reaffirmed the organization’s commitment, noting that patient safety remains central to the hospital’s mission and strategic direction. “Patient safety is at the heart of everything we do. This year’s theme, ‘Team Up for Patient Safety,’ reinforces a simple but powerful truth, safe care is achieved when we work together. At the Turks and Caicos Islands Hospital, we are committed to fostering a culture where collaboration, communication, and accountability guide every interaction. I am proud of our teams for their dedication throughout this month and beyond, as we continue to strengthen systems, empower our staff and patients, and deliver care that is consistently safe, reliable, and of high quality.”

The Turks and Caicos Islands Hospital remains dedicated to fostering a culture where safety is prioritized, communication is strengthened, and every voice, staff, patient, and family, is valued.

Healthcare professionals, community partners, patients, and families are encouraged to continue supporting patient safety by speaking up, staying informed, and working collaboratively to improve care outcomes.

Gut Health Linked to Lower Colorectal Cancer Risk According to Cleveland Clinic Dietitian

Published

on

March 19, 2026 – March is Colorectal Cancer Awareness Month, a time dedicated to highlighting the importance of prevention and early detection of one of the most common cancers affecting both men and women, according to the CDC.

March is Colorectal Cancer Awareness Month and according to the CDC, colorectal cancer is the third most common cancer for both men and women.

The good news is there are ways to help prevent it, like improving your gut health.

“A healthy gut and a diverse microbiome help decrease inflammation, and chronic inflammation we know can lead to increased risk of cancer, specifically colorectal cancer,” explained Julia Zumpano, RD, registered dietitian at Cleveland Clinic.

Zumpano said we can help improve our gut health by improving our diet.

She recommends eating foods that are high in fiber, such as whole grains, fruits, vegetables, legumes, nuts and seeds.

She also suggests adding fermented and probiotic foods into your diet. Some ideas include yogurt, kefir, kimchi and sauerkraut.

Zumpano notes that it can be overwhelming to eat a bunch of new foods at once, which is why it’s best to make a gradual transition.

“I would first begin by reducing processed foods and incorporating more fiber rich foods. And you’ll see your gut symptoms improve. So, if you have any symptoms like constipation or diarrhea, those things should improve. Now if you’re finding that you’re having gastrointestinal symptoms that aren’t going away despite making positive health changes, that’s when you should seek medical attention,” she advised.

Besides keeping a healthy diet, Zumpano said it’s also important to make sure you’re getting enough physical activity as exercise has been shown to help reduce a person’s risk for colorectal cancer.

By focusing on small sustainable lifestyle changes such as eating a fiber-rich diet, supporting gut health and staying physically active, people can take meaningful steps toward lowering the risk of colorectal cancer and improving their overall health.
