How to Manage Diabetes During the Summer Season

How to Manage Diabetes During the Summer Season

Jun. 22nd, 2022

The summer comes with longer and hotter days. Although many people look forward to the warmer weather and outdoor activities, it can be a difficult time for those who need to manage diabetes.

If you have diabetes, extreme heat can affect your blood sugar levels. The high temperatures can also damage the equipment and medicine essential for those with diabetes.1

Here are some facts about diabetes and the ways that the heat affects those with diabetes. We also have signs for diabetics to look out for and tips for managing diabetes in the summer.

What is Diabetes?

Diabetes is a chronic health condition that affects how the body turns food into energy.2

Most of the food you eat is broken down into glucose (sugar) and released into the bloodstream. When your body’s blood sugar increases, the pancreas releases insulin, allowing blood sugar into the cells that can be stored or used for energy. When someone has diabetes, the body either does not make enough insulin or the body is unable to use it.3

There are two main types of diabetes:

  • Type 1 diabetes is an autoimmune disease in which the immune system attacks cells in the pancreas, the primary producer of insulin. About 5-10% of people with diabetes have this type.4
  • Type 2 diabetes is when an individual’s body becomes resistant to insulin, which causes sugar to build up in the blood.5 Approximately 90-95% of people with diabetes have this type.6

How the Heat Affects Those with Diabetes

Did you know that individuals with type 1 and type 2 diabetes feel the heat more than those who are not diabetic? There are a few explanations for this:

  1. Diabetes can cause damage to blood vessels and nerves, which can affect the sweat glands and the body’s cool down process.
  2. People with diabetes can experience dehydration more quickly than others.
  3. Heat can change how the body uses insulin.

The heat can negatively impact a diabetic person based on what they’ve eaten, their hydration levels, and their activity levels.7

If the heat or being active causes an individual who is diabetic to sweat a lot, then they can become dehydrated, leading to a rise in glucose levels. Dehydration also reduces blood supply to the skin, which affects the body’s ability to absorb medication. This could be an issue if that person needs insulin.1

Additionally, extreme temperatures can affect medications left in the heat or direct sunlight. High temperatures can cause the medication to degrade and become ineffective.

Managing Diabetes During the Summer

Managing diabetes in the summer can be timely and confusing. Here are some signs to look out for if you’re diabetic, as well as some management tips to avoid any health concerns during the summer.

Signs to Look Out For

Heat exhaustion, hypoglycemia, and hyperglycemia are common among those with diabetes during long, hot days. If you or a loved one is diabetic, here are some signs to watch out for during the summer months.8

  • Drop in blood pressure
  • Feeling faint or dizzy
  • Weak or rapid pulse rate
  • Nausea
  • Sweating
  • Tremors
  • Extreme thirst

Tips for Management

Here are some important tips to make sure you or your loved ones with diabetes stay safe and healthy in the heat.9

  • Drink plenty of water
  • Avoid drinks that lead to water loss and spiked blood sugar levels, such as coffee and alcohol
  • Test your blood sugar as often as you can
  • Keep medicine and equipment out of the heat
  • Wear loose, light clothing to stay as cool as possible
  • Stay in the air conditioning or shade when possible
  • Have a plan in case you lose power, or if you’re going somewhere without air conditioning for an extended amount of time
  • Protect your skin since sunburn can raise blood sugar levels
  • Don’t leave medicine in direct sunlight or a hot car

If you’re diabetic and spend a lot of time in the heat or are very active during the summer, talk with your doctor about adjusting your insulin dosage if needed.
