Dr. Galina Smirnova, a neurologist, announced that people feel sleepy in the middle of the day during hot weather, which is a natural process and a protective mechanism of the body. In a conversation with the newspaper "Izvestia," the doctor notes that the feeling of drowsiness in hot weather has been known since ancient times, with designated rest periods in some countries, such as siestas in Spain and Argentina.
From a medical perspective, napping during hot weather can be beneficial, as metabolic processes slow down during sleep, providing relief to the body. However, long naps are not recommended to avoid sleep issues at night. She states, "The body's natural defense mechanism in heat is to slow down metabolic processes and heat production, accompanied by a decrease in blood flow and heart rate, causing the person to feel sleepy. Dehydration and electrolyte imbalance also contribute to drowsiness."
According to her, to maintain alertness in hot weather, one should wear appropriate clothing, preferably made from natural fabrics (like cotton and linen), which should be loose-fitting and long-sleeved, along with a hat and sunglasses.
She added, "The volume of physical exercise should be reduced or moved to early morning or evening. Avoid direct sunlight and stay in the shade as much as possible. Try to remain indoors during the hottest hours of the day."
Dr. Smirnova continued, "In the summer, it's important to increase fluid intake. Even if you do not feel thirsty, it is advisable to drink at least a little water. However, carbonated and sugary drinks containing caffeine are not recommended; only pure or mineral water is advised. Fresh fruit and vegetable juices, especially vegetable juices, can also be consumed."
The doctor emphasizes that mild drowsiness during the day is not a disease but a natural occurrence. If the aforementioned recommendations are followed, this drowsiness will not have any negative impact on health and the ability to work. She advises: "If feelings of weakness are significant, do not match the individual's activity level, and continue throughout the day—not just in the heat and do not decrease even on cold days or after rest—then a doctor should be consulted. Such symptoms may indicate thyroid or adrenal gland disease, anemia, depression, or issues with the kidneys and other internal organs."
