Do you get dizzy on a hot day? This is what you can do

These are the reasons why you feel dizzy on a hot day

Do you love sunbathing, but get dizzy when you get up from the beach chair? Or do you get sick if you are walking or exercising on a hot day? You are certainly not alone. This is what an expert says about the cause of dizziness and what you can do about it.

Low blood pressure

First of all, the dizziness you feel on a hot day can be caused by lower blood pressure. As Dr. Auldric Ratajczak explains to Women’s Health, to regulate your body temperature on a hot day, your blood vessels dilate. Blood flow is controlled by your brain to keep your skin and body cool. This change in blood flow can make you feel light-headed and dizzy.

To sweat

A second cause of dizziness in high temperatures is a large loss of moisture. You sweat a lot on hot days, so you lose more moisture than usual. If you don’t drink enough to replenish the moisture in your body, you may experience dizziness from this deficiency.


Feeling dizzy on a hot day is not always harmless. In addition to dizziness, do you also suffer from headaches, decreased appetite, excessive sweating, cramps, rapid breathing, a great thirst and a high body temperature? These are obvious symptoms of heatstroke. In this case, find some shade as soon as possible and drink plenty of (lukewarm) water. In severe cases, you can pass out from heatstroke. If this happens to someone in your area, call 911.

What can you do?

No heatstroke symptoms, but feeling dizzy? Fortunately, there are a few things you can do to avoid this nauseous feeling from the heat. So, you can drink pomegranate juice as soon as you feel the dizziness coming on. This drink hydrates and is good for your circulation. In addition, it is important – we cannot say this often enough – to drink enough water on a hot day. Consuming alcohol and caffeine will dehydrate you sooner, so drink extra water if you like a glass of wine, a cold beer or coffee. Furthermore, avoid the sun between noon and 4 pm, wear a hat, sunglasses and light clothes. Finally, eating lighter meals can help. Your metabolism does not have to run at full speed, so your body warms up less quickly.
