A Season of Pause — Winter Break in Punjab Brings Relief, Joy and Reflection As frost sets in and mornings grow colder, the people of Punjab get a much-anticipated pause. The Punjab government has announced that all public and private schools across the province will observe winter vacations from 22 December 2025 to 10 January 2026. For many families — especially in places like Sahiwal, Faisalabad, Multan, and other central/southern districts — this annual break is more than just days off. It is a season of relief, reconnection, and possibilities. Why the Break Matters (Beyond Textbooks) ❄️ Health & Safety First December and January bring biting cold, dense fog, and often treacherous commuting conditions across Punjab. For kids traveling long distances on bikes or school transport, early-morning cold and low visibility pose real risks. The winter holiday gives children a chance to avoid harsh weather and reduces chances of cold-related illnesses. Many parents feel a sense...
imunity system of human beings ?
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against harmful pathogens, such as bacteria, viruses, fungi, and parasites. The immune system plays a crucial role in maintaining overall health and preventing infections. Here are key components and functions of the human immune system:

Sufficient and quality sleep is crucial for a well-functioning immune system.
Components of the Immune System:
White Blood Cells (Leukocytes)
Neutrophils: Phagocytic cells that engulf and digest pathogens. Lymphocytes: Including T cells, B cells, and natural killer (NK) cells, which play roles in adaptive and innate immunity. Monocytes/Macrophages: Phagocytic cells that ingest and break down pathogens. Lymphoid Organs:Thymus: Where T cells mature
Bone Marrow: Site of blood cell production, including B cells and some immune system components. Spleen and Lymph Nodes:Spleen
Filters blood and removes damaged blood cells. Lymph Nodes: Bean-shaped structures that filter lymphatic fluid, trapping and destroying pathogens. Immune Molecules:Antibodies (Immunoglobulins)
Proteins produced by B cells that recognize and neutralize specific pathogens. Cytokines: Signaling molecules that coordinate immune responses.Complement System:
A group of proteins that enhance the immune system's ability to recognize and destroy pathogens. Functions of the Immune System:Recognition and Differentiation:
Ability to distinguish between the body's own cells (self) and foreign invaders (non-self).Barriers:
Physical barriers like the skin and mucous membranes prevent pathogens from entering the body.Innate Immunity:
Immediate, non-specific defense mechanisms that include phagocytic cells, natural killer cells, and inflammation.Adaptive Immunity:
Specific response tailored to each pathogen. Involves T cells (cell-mediated immunity) and B cells (antibody-mediated immunity). Immunological memory allows for a faster response upon subsequent exposure to the same pathogen.Immunological Memory:
After an initial exposure to a pathogen, the immune system "remembers" and mounts a quicker and more effective response upon re-exposure.Tolerance:
Ability to recognize and tolerate the body's own cells, preventing the immune system from attacking healthy tissues (autoimmune reactions). Factors Influencing Immune Function: Nutrition: Adequate intake of vitamins and minerals, particularly vitamins A, C, D, and zinc, is important for immune function.Sleep:
