Effects of Pollution on Health
Exposure to pollution has been widely recognized as detrimental to both lung and heart health. Numerous studies have established a strong connection between air pollution and an increased risk of heart disease, including heart attacks. Prolonged exposure to pollution can accelerate the aging of blood cells, induce oxidative stress, and cause a rapid accumulation of calcium deposits, which contribute to the development of atherosclerosis, the blockage of coronary arteries.
Why Waking Up Can be a Risky Time for Heart Attacks
When the alarm clock goes off in the morning, many people experience an unpleasant jolt. However, for individuals at risk of heart attacks, waking up can pose a significant danger. Interestingly, heart attacks occurring between 6 a.m. and noon are particularly hazardous. This heightened risk during the morning hours can be attributed to the activation of circadian-rhythm-based stress hormones, which promote increased blood flow. Additionally, factors such as dehydration and lower concentrations of heart medications in the system after a night of sleep may also contribute to this risk.
