How to Manage Your Diabetes in Extreme Summer Heat
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:
- Drink plenty of water.Staying hydrated is important for everyone during physical activity, and it’s especially critical if you have diabetes.
- 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.
- 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.
- 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. - 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.
- 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.
- 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.
- 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.
- 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 Successful Completion of 2026 Summer READY Programme
Providenciales, Turks and Caicos Islands – August 18, 2026 – Turks and Caicos Islands Hospital is pleased to announce the successful completion of its Summer READY Programme, a two-week internship initiative designed to provide high school students in Forms 3-5 with hands-on exposure to the healthcare environment and an opportunity to explore careers within the sector.
The programme, organised and hosted by the Training and Education Department, welcomed students into various clinical departments,
where they gained first-hand insight into the day-to-day operations of a healthcare facility and learned directly from healthcare professionals.
Throughout the two-week internship, students were exposed to different aspects of patient care and clinical operations while developing important workplace competencies, including communication, teamwork, professionalism, punctuality and responsibility. The experience was designed to complement classroom learning while helping students make more informed decisions about their future education and career pathways.
Vernessa Forbes, Training and Education Manager, said the Summer READY Programme reflects the hospital’s commitment to developing young people and creating meaningful opportunities for them to explore the healthcare profession.
“Summer READY is about giving our young people an opportunity to experience healthcare beyond what they may have seen or learned in the classroom. Over the two weeks, our students were able to interact with healthcare professionals, observe different clinical environments and gain a better understanding of the dedication and teamwork required to care for our patients. We were impressed by their enthusiasm, curiosity and willingness to learn, and we hope this experience has inspired them to consider the many rewarding careers available in healthcare.”
By rotating through and gaining exposure to various clinical departments, students were also able to see that healthcare extends beyond the roles most commonly associated with a hospital. The programme introduced them to the range of skills, disciplines and professionals that work together to deliver safe, compassionate and high-quality patient care.
Dr. Denise Braithwaite-Tennant, Chief Executive Officer, said the hospital has an important role to play in building the human capacity needed to support the future development and sustainability of healthcare in the Turks and Caicos Islands.
“As a hospital, our responsibility extends beyond providing healthcare services today; we also have an important role in helping to develop the people who will deliver and lead healthcare tomorrow. Human capacity building is essential to the long-term sustainability of our health system, and programmes such as Summer READY allow us to introduce young people to healthcare careers early, nurture their interests and help them understand the educational and professional pathways available to them.
By opening our clinical environment to students and providing mentorship and practical exposure, we are helping to build a pipeline of
future nurses, physicians, allied health professionals and other healthcare workers. We want our young people to see that there is a place for their talents within the health sector and, importantly, that they can build rewarding careers while contributing to the health and development of the Turks and Caicos Islands. We are proud to play our part in investing in the next generation and strengthening our country’s future healthcare workforce.”
The programme concluded with the presentation of certificates of completion to the students, recognizing their successful participation and commitment throughout the two-week internship.
Turks and Caicos Islands Hospital congratulates all of the students who successfully completed the Summer Ready Programme and extends its appreciation to the clinical teams, supervisors and staff members who provided mentorship, guidance and practical learning opportunities throughout the programme.
Through the Summer READY Programme and its wider education, training, internship and professional development initiatives, Turks and Caicos Islands Hospital remains committed to supporting national human capacity development. By partnering with educational institutions, government agencies and other stakeholders, and by providing mentorship and practical learning opportunities within the healthcare environment, the Hospital aims to strengthen the pipeline of skilled healthcare professionals needed to meet the evolving health needs of the Turks and Caicos Islands.
NASSAU, Bahamas — More Bahamians are accessing HIV and sexually transmitted infection-related healthcare through National Health Insurance, a trend the NHI Authority says should be viewed positively.
NHIA stressed in an August 6 statement that its 2025 figures measure healthcare utilisation, not newly diagnosed infections. They include beneficiaries screened, treated, monitored or receiving follow-up care, including people diagnosed previously.
“Increased utilisation of these services should be viewed as a positive development,” NHIA said.
The Authority pointed to “greater enrolment and use of NHI, improved access to screening and testing, continued treatment and monitoring of existing conditions, and increased willingness to seek medical care.”
The development comes amid a mixed three-year HIV picture. New diagnoses rose from 130 in 2023 to 156 in 2024, before declining to 142 in 2025.
NHIA said increased utilisation demonstrates that more beneficiaries are accessing needed healthcare and actively managing their health, reinforcing the importance of screening, early diagnosis and continued treatment.
WASHINGTON, D.C. — The Americas has recorded 47,459 confirmed measles cases and 44 deaths in 2026, the region’s highest case count in 22 years, prompting the Pan American Health Organization (PAHO) to urge stronger vaccination, surveillance and rapid outbreak response.
As of July 18, cases were already more than triple the 15,011 recorded during all of 2025. Guatemala, Mexico, the United States and Peru
account for 95% of confirmed cases. Guatemala leads with 30,371 cases and 26 deaths, followed by Mexico with 12,255 cases and 17 deaths.
PAHO classifies the regional public health risk as very high, citing active outbreaks, immunity gaps, international travel and populations with inadequate vaccination coverage.
The organization says prevention starts with vaccination. Countries are being urged to achieve and maintain at least 95% coverage with two doses of measles-containing vaccine, particularly protecting children and under-vaccinated communities.
Measles spreads through the air when an infected person breathes, coughs or sneezes. Symptoms can include fever, cough, runny nose, red eyes and a rash.
PAHO is urging health authorities to detect suspected cases early and respond rapidly to stop transmission. Unvaccinated and under-vaccinated people, young children and communities with limited healthcare access face increased risk of severe illness and death.
