Theo các nhà nghiên cứu, những người không muốn ngủ có nguy cơ mắc bệnh đau tim gấp đôi nguy cơ đau tim bình thường . Các nhà khoa học cho biết thức giấc thường xuyên vào ban đêm được xem như một lời cảnh báo về sức khoẻ không lành mạnh trong tương lai. Nghiên cứu gần đấy cho thấy rằng 13.000 người là những người phải vật lộn để ngủ vào ban đêm là 99% có nguy cơ bị đau tim hoặc đau thắt ngực nghiêm trọng. Những người mất hơn nửa giờ để ngủ hoặc ngủ ít hơn sáu giờ đồng hồ cũng có nguy cơ gia tăng bệnh . Nghiên cứu của Nhật Bản đã không xác định được lý do tại sao lại có một mối liên hệ mạnh mẽ giữa giấc ngủ và sức khoẻ của trái tim. Nhưng các nhà khoa học cho biết, hành động thức tỉnh liên tục có thể gây ra tình trạng "kích hoạt quá mức" trong hệ thần kinh, làm tăng nhịp tim và huyết áp, gây thêm căng thẳng lên tim. Ngủ kém cũng có thể là triệu chứng của tình trạng sức khoẻ kém, có nghĩa là những người có vấn đề về tim ít có khả năng ngủ ngon giấc. Cuộc nghiên cứu cho thấy những người phải mất hơn nửa giờ để ngủ có nguy cơ đau tim tăng 52% và 48% nguy cơ cơ thể bị đột quỵ tăng cao. Và những người có ít hơn sáu giờ để ngủ một đêm là 24 % nhiều khả năng bị đau tim.
