The deaths of two UAE residents while exercising within a few days of each other have once again drawn attention to heart health, underlying conditions, and the risks of strenuous activity without proper physical preparation.

In one instance, Mohammed Safwan Shanu, a 38-year-old Indian national and well-known figure in the cricket community, suddenly collapsed and died during a match in Dubai. A few days later, Anwar Siddique, a 42-year-old Indian national, collapsed and passed away while playing badminton.

Doctors emphasize that the exact cause of such incidents can only be determined through medical investigations and should not be attributed to a single factor without professional findings. However, these events have reignited the debate over undiagnosed heart disease and the dangers of intense exercise without adequate conditioning.

Cardiologists warn that being young, lean, or appearing active is not a guarantee of heart health. Certain cardiac conditions can remain asymptomatic for years, only manifesting during periods of intense activity or sudden physical strain.

Medical professionals highlight a group known as "weekend warriors"—individuals who lead sedentary lifestyles during the week but engage in high-intensity activities such as football, cricket, badminton, or cycling on weekends. This pattern can place significant strain on the heart, particularly for smokers or those with hypertension, diabetes, high cholesterol, or a family history of heart disease.

Specialists also stress the distinction between a heart attack and cardiac arrest. A heart attack typically occurs when blood flow to a part of the heart is reduced or blocked, often presenting with chest pain, sweating, nausea, shortness of breath, or radiating pain. In contrast, sudden cardiac arrest is caused by an electrical malfunction in the heart, leading to an abrupt loss of consciousness—a condition that can be fatal within minutes without immediate resuscitation and the use of a defibrillator.

Doctors warn that symptoms such as chest pain or pressure, unusual shortness of breath, dizziness, fainting, heart palpitations, extreme fatigue, or a family history of sudden death should never be ignored.

The extreme summer heat in the UAE further escalates the risks associated with strenuous exercise. Dehydration, electrolyte imbalances, and increased cardiac strain are common consequences of physical exertion in high temperatures and humidity.

Experts recommend that individuals over the age of 35, or those with risk factors such as high blood pressure, diabetes, high cholesterol, smoking, or a family history of heart disease, undergo a medical evaluation before beginning intense or competitive sports. Such assessments may include blood pressure checks, blood sugar and lipid profiles, an electrocardiogram (ECG), and, if necessary, a stress test.

The message from medical professionals is clear: while exercise is vital for health, it must be consistent, gradual, and performed with awareness of the body’s signals. Sudden death during exercise does not imply that physical activity is dangerous; rather, it serves as a reminder that heart health cannot be judged solely by age, physical appearance, or activity levels.
