Never Work Immediately After Meals!
A 30-something patient from a private company reported persistent dizziness, insomnia, mental tension, memory decline, general fatigue, and sluggish reactions for months. After thorough examination by a neurologist, the diagnosis was chronic brain overuse—specifically, prolonged intense mental labor immediately after meals. Doctors thus warn those engaged in intellectual work: always rest for at least half an hour after eating before resuming work.
After meals, blood redistributes to digestive organs, causing relative cerebral hypoxia, leading to drowsiness. Additionally, increased levels of amino acids from digested food suppress brain alertness. Working under such conditions inevitably burdens the brain. Those with family history or risk factors for cardiovascular disease face heightened risks of heart and brain disorders if they start intense mental work immediately after eating. Prevention is crucial.
Some try to overcome post-meal drowsiness by jumping straight into work, using cold water to wash face, slapping the head, or applying menthol ointment. These actions harm digestion and fail to restore brain function quickly. Only allowing the brain to rest fully for 30 minutes, calming emotions, prevents long-term brain damage and lifelong suffering caused by short-term urgency.
