Hello,
With the question “Is it okay to have trouble breathing, heart palpitations when the weather is hot? ", the doctor would like to answer as follows:
On the background of the high temperature of the weather, all activities and metabolism in the body are affected. To adapt to hot weather, the body adjusts by increasing sweating and dilating peripheral blood vessels. When you sweat a lot, the body will lose water, reducing the volume of circulating blood, while the heart still has to contract to ensure that enough blood is pumped throughout the body. Due to the reduced blood volume, the heart has to work harder, increasing the force of contraction and increasing the number of beats per minute. On the other hand, when exercising, sweating a lot, losing a lot of fluid, the muscles require more blood supply.
When too much fluid is lost, body temperature rises, organs are damaged, especially the nervous and cardiovascular systems, the patient is very tired, loses consciousness, lacks concentration, heart palpitations, blood pressure increases, You should see a cardiologist early, to detect underlying cardiovascular disease early (if any), to have a treatment method and prevent the underlying disease from worsening in hot weather.
You should stay indoors during the hottest time of the day, from 10am to 3pm, if possible, in an air-conditioned place, wear loose and comfortable clothes. If you have to go out, you need to wear loose, cool clothes and a hat. If it is not necessary, go early in the morning or in the evening. Do not eat too full, eat easy-to-digest liquid foods, limit the amount of salt you eat. You should eat a lot of fresh fruits such as oranges, tangerines, bananas, grapes to provide a full range of electrolytes for the body, do not drink alcohol, beer, coffee. You need to take all the medicine as directed by your doctor. Drink enough water as recommended is about 2 liters of water / day (including water in meals).
However, people with heart failure should avoid drinking too much water because it increases the burden on the cardiovascular system. People with heart disease need to monitor their weight every day to make up for the right amount of water, for example, losing 1 kg of weight means losing 1 liter of water, so they need to drink the corresponding amount of water to make up for it. Limit physical activity in hot weather to avoid loss of salt and water and increase the burden on the heart.
If you still have questions about shortness of breath, heart palpitations in hot weather, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
