As the temperature rises and days get longer, many of us often find ourselves relaxing in the pool throughout the summer. However, for some individuals, the summer season can bring challenges, particularly when it comes to managing low blood pressure. It is not uncommon for blood pressure to decrease during hot weather, leading to symptoms that can disrupt daily activities. In this article, Dr Shobha Subramanian Itolikar, Consultant-Internal Medicine, Fortis Hospital Mulund, helped us why low blood pressure happens in summer and signs to look out for.
Low Blood Pressure In Summer
Low blood pressure, also known as hypotension, is a condition characterised by a decrease in blood pressure below normal levels. During the summer, several factors can contribute to low blood pressure:
Dehydration
Hot weather and increased sweating can lead to dehydration, causing a decrease in blood volume and a subsequent drop in blood pressure.
Vasodilation
In warm temperatures, blood vessels tend to dilate to help cool down the body. This dilation can cause a decrease in blood pressure.

Lack of Salt Intake
Excessive sweating during summer activities can lead to salt depletion. Sodium plays a role in maintaining blood pressure, and low levels can contribute to hypotension.
Signs Of Low Blood Pressure
Recognising the signs of low blood pressure is crucial for managing the condition. Common symptoms include:
- Lightheadedness or dizziness
- Fatigue or weakness
- Blurred vision
- Fainting or feeling faint
- Nausea
- Rapid or shallow breathing
If you experience any of these symptoms, it's important to take appropriate measures to manage your blood pressure.
Lifestyle Changes To Manage Low Blood Pressure
Fortunately, there are several lifestyle changes you can make to manage low blood pressure, especially during the summer months:
1) Stay Hydrated
Drink plenty of water throughout the day to avoid dehydration and maintain blood volume. Caffeine and alcohol usage should be limited as they can contribute to dehydration.
2) Increase Salt Intake
If your healthcare provider approves, slightly increasing your salt intake can help raise blood pressure. However, it's essential to consult with a medical professional before making any significant changes to your diet.
3) Wear Compression Stockings
Compression stockings can help improve blood circulation and prevent blood pooling in the lower extremities, thereby reducing the risk of low blood pressure.
4) Avoid Prolonged Standing Or Sitting
If possible, avoid long periods of standing or sitting in hot environments. Take breaks, stretch, and move around to promote blood flow.
5) Stay Cool
Avoid excessive heat exposure by seeking shade, using fans or air conditioning, and wearing lightweight, breathable clothing. This can help minimise vasodilation and maintain blood pressure.
6) Exercise Regularly
Engaging in regular physical activity can help improve cardiovascular health and maintain blood pressure within a healthy range. However, it's important to consult with a healthcare professional before starting any new exercise regimen.
