Ahoi Ashtimi (also called HOI or Ahoi Ekadashi) is a fasting festival observed by mothers for the well-being, longevity, and prosperity of their children. It is primarily celebrated in North India, where women fast and perform rituals for their offspring's health and happiness.

White coating on a baby's tongue is oral thrush, a common yeast infection (Candida albicans) in infants. Diaper rash affects the diaper area, milk rash is different, and internal yeast infection would have other symptoms.

When skin is exposed to sunlight, ultraviolet B (UVB) rays penetrate the skin and convert 7-dehydrocholesterol (a compound in skin oils) into Vitamin D3 (cholecalciferol). This is the primary way humans obtain Vitamin D, which is essential for bone health, immune function, and calcium absorption. The process is a natural biochemical reaction, not related to bacteria or tanning.

Heat exhaustion occurs when the body loses excessive amounts of water and salt through sweating. This depletion of fluids and electrolytes impairs the body's ability to regulate temperature and can lead to dizziness, weakness, and nausea if not treated.

When skin is exposed to sunlight, ultraviolet (UV) rays penetrate the skin and convert a compound called 7-dehydrocholesterol into Vitamin D3 (cholecalciferol). This is the body's primary natural source of Vitamin D, essential for bone health, immune function, and overall well-being. The other options are incorrect: infrared light doesn't kill bacteria in this context, resistance power isn't directly increased by sunlight, and tanning is a side effect not the health benefit.

Maintaining a healthy weight through diet and exercise, and limiting alcohol consumption, are proven strategies to reduce breast cancer risk. Alcohol increases estrogen levels, and excess body fat produces estrogen after menopause - both are modifiable risk factors.

Interferons are signaling proteins released by host cells in response to viruses, and they are also used as a medication to treat certain types of cancer, such as hairy cell leukemia and melanoma. They help modulate the immune system to fight malignant cells. Thus, cancer is the correct application among the choices.

MI stands for Myocardial Infarction, the medical term for heart attack. 'Myocardial' refers to the heart muscle (myocardium), and 'Infarction' means tissue death due to lack of blood supply. Note: the correct spelling is 'Infarction' not 'Infraction'.

Alcohol impairs brain function, specifically slowing down your reflexes and reaction time. When driving, quick reactions are essential for responding to unexpected hazards. Even small amounts of alcohol can significantly increase the risk of accidents.

True - nicotine is a stimulant that triggers immediate cardiovascular effects. Within seconds of inhalation, nicotine activates the sympathetic nervous system, causing release of catecholamines like epinephrine, which increases heart rate and blood pressure by 10-20 mmHg or more.

Studies have shown a link between periodontal (gum) disease and cardiovascular disease. Regular brushing and good oral hygiene may reduce inflammation markers associated with heart disease risk, though the evidence is not yet conclusive.

Yellow is the color used in medical settings to flag infectious diseases and caution. This is seen in isolation protocols, warning signage, and medical records. Pink, maroon, and magenta are not standard colors used for denoting infectious illness in medical practice.

Cancer causes approximately 9-10 million deaths globally each year, while AIDS-related deaths number around 600,000-700,000 annually. Therefore, more people die of cancer than AIDS.

Regular tooth brushing actually REDUCES heart disease risk rather than increasing it. Extensive research has established a strong link between gum disease (periodontitis) and cardiovascular disease. Poor oral hygiene allows bacteria to accumulate in the mouth, enter the bloodstream through gums, and contribute to inflammation and arterial plaque formation. Regular brushing and flossing remove plaque bacteria, reducing gum inflammation and systemic bacterial load. Studies consistently show that people with good oral hygiene habits have lower rates of heart attacks, strokes, and other cardiovascular problems.

Alcohol consumption dehydrates the body, provides empty calories, impairs muscle recovery and protein synthesis, and is counterproductive to fitness goals. Yoga, running, and swimming all contribute to improved physical fitness when done regularly.
