As temperatures in the UAE rise sharply this summer, many residents prefer to stay indoors to avoid the intense heat. While avoiding the scorching midday sun helps protect against heat-related illnesses, doctors note that spending most of the day sedentary with minimal activity carries its own health risks.
Risks of a Sedentary Lifestyle
Health experts warn that a sedentary indoor lifestyle gradually negatively affects almost all body systems. This increases the likelihood of weight gain, muscle stiffness, impaired blood circulation, Vitamin D deficiency, sleep problems, and low mood. They emphasize that the solution lies in adapting daily habits by maintaining activity in safer ways.
Specialists' Advice on Activity
Dr. Salma Khanam Patan, an internal medicine specialist at Medicare Hospital Sharjah, stated that the main point is that avoiding daytime heat does not mean completely giving up movement. She noted that incorporating regular activity throughout the day, even indoors in air conditioning, can significantly improve both physical and mental well-being.
Patan explained that prolonged sitting or lying down reduces muscle activity, slows blood flow, and contributes to stiffness, back and neck discomfort, as well as reduced flexibility. Furthermore, prolonged time indoors can limit exposure to natural daylight, which is vital for regulating internal biological clocks and ensuring healthy sleep.
Impact on Emotional State
According to Dr. Patan, physical inactivity also affects emotional well-being. She pointed out that limited movement and long periods indoors can lead to decreased energy levels, reduced motivation, and mood changes, as physical exercise promotes the release of substances that support emotional state.
Doctors also warn that maintaining a sedentary lifestyle for weeks or months can increase the risk of developing chronic diseases. Reduced physical activity leads to fewer calories burned, making weight gain more likely and increasing the risk of conditions such as type 2 diabetes, high blood pressure, and cardiovascular disease.
Circulation and Muscle Problems
Another issue is impaired blood circulation, especially in people who spend most of the day sitting. Dr. Patan explained that insufficient physical activity slows blood flow, particularly in the legs, which can cause swelling, discomfort, and, in some individuals with additional risk factors, increase the probability of clot formation.
Moreover, without regular movement, muscle strength and joint mobility decrease, and inactivity leads to poorer sleep quality, which in turn affects overall energy levels and health.
Other Doctors' Views
Dr. Zara Ahmed, an emergency medicine specialist at RAK Hospital, reported observing patients who become noticeably less active during hotter months. She noted that reduced activity in the summer can trigger weight gain, muscle stiffness, poor circulation, and flare-ups of conditions like diabetes, hypertension, and heart disease.
Ahmed added that much of the time spent indoors often means less sunlight, which increases the risk of Vitamin D deficiency, essential for bone, muscle, and immune function. She also highlighted the growing problem of excessive screen time.
In Dr. Ahmed's opinion, whether it is working on a laptop, scrolling through a phone feed, or binge-watching television, prolonged screen use can contribute to hypodynamia, cause eye strain, headaches, poor posture, and disrupt sleep, especially if screens are used late in the evening.
Recommendations for Staying Fit
Doctors reassure residents that they do not need intensive workouts to stay healthy in the summer; consistency is more important than intensity. The safest times for outdoor activities are shortly after sunrise or late in the evening when temperatures are lower. Intense exercise should be avoided between late morning and late afternoon when peak heat and humidity are reached.
For many people, there are safe indoor alternatives. Experts advise walking in shopping malls, exercising in gyms, swimming in temperature-controlled pools, attending fitness classes, practicing yoga or Pilates, or following home workout programs.
Dr. Ahmed advised that even 20–30 minutes of walking daily, combined with stretching and strength exercises, can help maintain physical fitness, improve sleep, and support heart health. She also mentioned the growing popularity of mall walks and indoor fitness events in the summer, suggesting online yoga and Zumba classes as practical ways to stay active at home. For children, she recommended indoor summer camps that encourage movement and reduce excessive screen time.
General Health Recommendations
Dr. Somaya Shamsai, an internal medicine specialist at Aster Clinic JLT, recommended that adults aim for at least 150 minutes of moderate physical activity each week, supplemented with strength training two or more days a week. She advised conducting workouts in air-conditioned spaces, pools, or at home during the summer, while maintaining hydration.
Shamsai added that people with diabetes, high blood pressure, or heart conditions should consult a doctor before starting a new exercise program. She also noted that despite the sunny climate of the UAE, Vitamin D deficiency remains common because many people avoid being outdoors. She believes that brief exposure to the sun outside peak UV hours, combined with testing and supplementation if necessary, can help maintain healthy Vitamin D levels.
Doctors insist that residents carefully monitor for signs of heat exhaustion during outdoor activities, including dizziness, headache, nausea, confusion, muscle spasms, and excessive fatigue. If symptoms appear, activity must stop immediately, the person must move to a cool place, rehydrate, and seek medical attention if symptoms persist.
Their advice is simple: avoid dangerous heat, but do not give up movement. By choosing cooler times of the day, utilizing indoor fitness options, and maintaining consistent activity, residents can protect their physical and mental health throughout the long summer in the UAE.
