Sugar rush意思

"Sugar rush" is an English term that refers to the sudden, brief feeling of excitement, energy, or euphoria that some people experience after consuming a large amount of sugar. This term is often used colloquially and is not a medical term.

The phenomenon is thought to be caused by a rapid increase in blood sugar levels, which can lead to the release of the hormone insulin. Insulin helps to regulate blood sugar levels by signaling cells to absorb glucose from the blood. When insulin levels are high, it can also lead to the release of the hormone epinephrine (adrenaline), which is associated with the body's fight-or-flight response and can cause a person to feel more alert and energetic.

However, the sugar rush is often followed by a "crash," as blood sugar levels drop back down, leading to feelings of fatigue and irritability. This crash can be more pronounced if a person's blood sugar levels were very high to begin with.

It's important to note that not everyone experiences a sugar rush, and the effect may be more psychological than physical for some people. Additionally, consuming large amounts of sugar can have negative effects on overall health, including contributing to obesity, diabetes, and other health problems.
