It is well-known that the effect of coffee on mood is related to its content in caffeine. But why caffeine has such a strong effect on us? Caffeine operates using the same mechanisms of amphetamines, cocaine, and heroin to stimulate the brain, though with milder effects. It manipulates the same channels as the other drugs, and that is one of the things that gives caffeine its addictive qualities. There is a chemical in our brain called adenosine, that binds to certain receptors and slows down nerve cell activity when we are sleeping. To a nerve cell, caffeine looks like adenosine and it binds to the adenosine receptors. However, as it's not really adenosine, it doesn't slow down the cell's activity like adenosine would. So the cell cannot "see" adenosine anymore because caffeine has taken up all the receptors adenosine binds to. Then instead of slowing down because of the adenosine level, the cells speed up. The pituitary gland sees all of this activity and thinks some sort of emergency must be occurring, so it releases hormones that tell the adrenal glands to produce adrenaline. Adrenaline is the "fight" hormone, and it makes your heart to beat faster, the breathing tubes to open up, the liver to release sugar into the bloodstream for extra energy and your muscles to tighten up, ready for action. Because of this, after consuming a big cup of coffee your muscles tense up, you feel excited and you can feel your heart beat increasing. Moreover, as amphetamines, caffeine also increases the levels of dopamine, which is associated with the pleasure system of the brain, providing feelings of enjoyment and reinforcement. Hal ini juga diketahui bahwa efek kopi pada suasana hati yang berhubungan dengan isinya kafein. Tapi mengapa kafein memiliki efek yang kuat pada kita?

It is well-known that the effect of coffee on mood is related to its content in caffeine. But why caffeine has such a strong effect on us? Caffeine operates using the same mechanisms of amphetamines, cocaine, and heroin to stimulate the brain, though with milder effects. It manipulates the same channels as the other drugs, and that is one of the things that gives caffeine its addictive qualities.

Hal ini juga diketahui bahwa efek kopi pada suasana hati yang berhubungan dengan isinya kafein. Tapi mengapa kafein memiliki efek yang kuat pada kita? Kafein beroperasi menggunakan mekanisme yang sama amfetamin, kokain, dan heroin untuk merangsang otak, meskipun dengan efek lebih ringan. Memanipulasi saluran yang sama dengan obat lain, dan itu adalah salah satu hal yang memberikan kafein kualitas adiktif nya. Ada bahan kimia dalam otak kita yang disebut adenosin, yang mengikat reseptor tertentu dan memperlambat aktivitas sel saraf saat kita tidur. Untuk sel saraf, kafein terlihat seperti adenosin dan berikatan dengan reseptor adenosin. Namun, karena itu tidak benar-benar adenosin, itu tidak memperlambat aktivitas sel seperti adenosin akan. Jadi sel tidak bisa "melihat" adenosin lagi karena kafein telah mengambil semua reseptor adenosin mengikat untuk. Kemudian bukannya memperlambat karena tingkat adenosin, sel mempercepat. Kelenjar pituitari melihat semua kegiatan ini dan berpikir semacam darurat harus terjadi, sehingga melepaskan hormon yang memberitahu kelenjar adrenal untuk menghasilkan adrenalin. Adrenalin adalah "pertarungan" hormon, dan itu membuat jantung Anda berdetak lebih cepat, tabung pernapasan untuk membuka, hati untuk melepaskan gula ke dalam aliran darah untuk energi ekstra dan otot-otot Anda untuk memperketat, siap beraksi. Karena itu, setelah mengkonsumsi secangkir besar kopi otot Anda tegang, Anda merasa bersemangat dan Anda bisa merasakan hati Anda mengalahkan meningkat. Selain itu, sebagai amfetamin, kafein juga meningkatkan kadar dopamin, yang berhubungan dengan sistem kesenangan otak, memberikan perasaan kenikmatan dan penguatan.
