Vertigo is a feeling of lightheadedness or imbalance, and vertigo characterized by a spinning or off-balance sensation.
High temperatures also lead to increased health problems. High temperatures often lead to the risk of heatstroke or heat exhaustion, as the body’s ability to regulate temperature can be overwhelmed, leading to a range of uncomfortable and potentially dangerous symptoms, including dizziness.
Why do we feel dizzy when it is too hot?
There are many reasons why we may feel faint or dizzy in hot weather. Dehydration is one of the main causes of health problems in the summer. When the body loses more fluids and electrolytes than it needs, this can lead to dehydration. This fluid imbalance can reduce blood flow to the brain, leading to dizziness.
As the body tries to cool itself, blood vessels dilate (widen) to bring more blood closer to the skin’s surface. This can lower blood pressure and reduce blood flow to the brain, leading to dizziness.
How to control dizziness when the outside temperature is too hot?
You can follow these 4 principles to control dizziness:
- Stay hydrated: This is the golden rule that everyone must follow. Drink plenty of water and electrolyte-rich fluids, such as coconut water, to replace the fluids and minerals lost through sweat.
- Limit alcohol and caffeine: These substances can cause the body to lose more water and weaken the ability to regulate temperature, increasing the risk of dizziness and fainting.
- Wear breathable clothing: Choose breathable fabrics that allow sweat to escape and help the body cool down more effectively.
- Avoid prolonged outdoor activities: If possible, limit prolonged exposure to sunlight and high temperatures, especially during the hottest times of the day.
Beyond these basics, it’s important to be aware. Recognize symptoms like excessive sweating, nausea, headaches, and rapid heart rate, which can indicate a more serious heat-related condition that requires medical attention. By understanding what causes dizziness when the outside temperature is too hot and taking proactive steps to control your body’s response to high temperatures, you can reduce your risk of fainting and enjoy the summer months more safely.
If your dizziness becomes more severe or you have signs, symptoms of heat exhaustion, take the following steps immediately:
- Call for medical help.
- Move to a cool or shady area.
- Loosen or remove excess clothing.
- Lie down with your feet elevated.
- Use whatever means are available to cool your body, such as a fan or placing ice-soaked towels on your skin.
- Slowly sip water or other fluids. But DO NOT drink anything if you suspect you have heatstroke. Wait until help arrives. People with heatstroke are at risk of inhaling liquids (aspiration), which can be dangerous.
When emergency personnel arrive, they will immediately look for any signs of heatstroke. They may do things to cool you down, such as fanning you after spraying cool mist water on your skin. They may take you to the hospital so you can get intravenous fluids or other cooling methods more quickly.
If your heat exhaustion progresses to heatstroke, you will need to stay in the hospital for several nights or longer. Your doctor will provide additional treatment and monitor your condition.
