New Year celebrations often involve alcohol, and overindulgence can lead to several physical signs of distress. These include intense headaches and dehydration due to alcohol's diuretic effects, persistent nausea and vomiting from gut irritation, and extreme fatigue caused by disrupted sleep cycles. Other indicators are clumsy coordination and tremors affecting balance, and memory lapses due to the hippocampus being overloaded. Remedies can help the body recover from these symptoms.
