Heat waves are increasingly frequent in Spain and their effects go far beyond the discomfort of sleeping badly or not being able to go out in the central hours of the day. Extreme temperatures affect the bodyThey favor dehydration and can cause dizziness, exhaustion or even serious complications if precautions are not taken.
Although everyone is exposed to these risks, There are especially vulnerable groups: older people, young children and who live with chronic diseases. Among them, patients with diabetes occupy a prominent place because their metabolism is directly altered by heat.
Heat and its impact on diabetes
According to Sanitas, high temperatures can modify the way the body processes carbohydrates and insulin. This means that an intense heat day can favor unexpected hypoglycemia or decompensations That, sometimes, they go unnoticed because the initial symptoms are confused with the fatigue or fatigue typical of summer.
Marta Carrasco, head of endocrinology of the Sanitas La Moraleja University Hospital, explains it: “Heat can accelerate insulin absorption and make blood glucose levels fall faster. If we add sweat, fluid loss or appetite changes, the risk of hypoglycemia increases considerably. ”
It’s not just about medication. In summer it is usual to modify the routines: eat less, skip meals, improvise with light fruit or snack, or reduce physical activity without adjusting the treatment. “Walking under the sun or walking in mid -afternoon may seem harmless, but if there is no correct hydration, important imbalances can occur in glycemic control”Carrasco warns.
How to protect yourself from heat
From Sanitas they insist that summer does not have to be synonym for complications, provided that some simple precautions are taken.
For example, Drink water on a regular basis Although it is not thirsty it is key, because waiting to feel it already means going one step behind in dehydration. It is also convenient Organize meals Not to skip any and Always be at hand something that provides quick glucoselike a piece of fruit or a juice, in case an unexpected drop appears.
Another fundamental aspect is Care of medication: Insulin does not tolerate high temperatures well, so to keep it in a fresh place or in small portable devices can make a difference. In addition, specialists remember that walks or exercise should be done early in the day or at sunset, when the sun squeezes less.
Finally, it is important to listen to the body: dizziness, palpitations, cold sweats or mental confusion are signs that something is not doing well. Acting quickly can prevent a slight situation from becoming an urgency.
