Caffeine has a half-life of about 5 hours, meaning that it takes about 5 hours for the body to eliminate half of the caffeine that has been consumed.<\/p>\n<p>Caffeine is a central nervous system stimulant that increases alertness, attention, and energy levels. It can also improve mood and cognitive function. However, caffeine can also cause side effects such as anxiety, insomnia, and headaches. In high doses, caffeine can be toxic.<\/p>\n<p>The amount of caffeine in a serving of tea or coffee varies depending on the type of tea or coffee, the brewing method, and the size of the serving. A cup of brewed coffee typically contains about 95 milligrams of caffeine, while a cup of brewed tea typically contains about 47 milligrams of caffeine.<\/p>\n<p>Lemon water does not contain caffeine.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Join Our Telegram Channel Subscribe on YouTube<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20],"tags":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v22.2 (Yoast SEO v23.3) - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>The alkaloid caffeine is present in<\/title>\n<meta name=\"description\" content=\"Caffeine is a central nervous system stimulant that increases alertness, attention, and energy levels.
