Did you know that your skin also plays an important role in blood sugar control?
That’s right, and sunburns can negatively affect glucose levels, especially in people with type 2 diabetes. In this post, we will explain how this relationship works, give you some tips to protect yourself from the sun and take care of your health, and offer you additional information about studies, statistics, and other related resources.

How sunburns affect blood sugar
Sunburns are an inflammatory response of the body to excessive exposure to ultraviolet (UV) rays from the sun. This inflammation releases hormones such as cortisol and prostaglandins, which can increase insulin resistance.
Insulin is a hormone that helps the body use glucose (sugar) as an energy source. When there is insulin resistance, the body cannot use glucose efficiently, which can lead to an increase in blood sugar levels.
Studies supporting this relationship
A study published in the journal Diabetes Care found that people with type 2 diabetes who had sunburns had a higher risk of having high blood sugar levels in the next 24 hours.
Another study, published in The Journal of Clinical Endocrinology & Metabolism, found that sunburns can increase insulin resistance in people with type 2 diabetes.
Relevant statistics
- Type 2 diabetes is the most common form of diabetes, affecting more than 400 million people worldwide.
- People with type 2 diabetes are at increased risk of developing diabetes-related complications, such as heart, kidney, and eye disease.
- Sunburn is one of the most common causes of skin cancer.
What can you do to protect yourself?
1. Use sunscreen:
It is essential to use a broad-spectrum sunscreen with an SPF of 30 or higher every day, even on cloudy days. Apply it generously to all exposed areas of skin 30 minutes before going out in the sun and reapply every two hours, or more often if you sweat or swim.
2. Cover your skin:
Wear protective clothing such as wide-brimmed hats, sunglasses, and long-sleeved shirts to cover as much skin as possible.
3. Avoid the sun during peak hours:
The intensity of UV rays is highest between 10 am and 4 pm. If possible, try to avoid direct exposure to the sun during these hours.
4. Stay hydrated:
Drinking plenty of water helps keep your skin hydrated and reduces the risk of sunburn.
5. Monitor your blood sugar levels:
It is important to monitor your blood sugar levels more often after sun exposure, especially if you have type 2 diabetes.
6. Choose the right sunscreen:
Look for a sunscreen that is:
- Broad-spectrum, which means it protects against UVA and UVB rays.
- With an SPF of 30 or higher.
- Water resistant, if you will be swimming or sweating.
- Fragrance-free and paraben-free, if you have sensitive skin.
7. Consult your doctor:
Your doctor or diabetes educator can help you choose the right sunscreen for you and give you personalized recommendations for sun protection.
