Drink water for a long time, have regular meals, and eat less and more meals. Students like to go out for a midnight snack after studying at night, which is the most taboo. Try not to eat for three hours before going to bed. Because of accommodation, lifting and kicking your legs after getting up in the morning can promote blood circulation, and long-term persistence can achieve the effect of stovepipe. Try not to let your body feel cold. I hope I can help you and wish you success in your studies.
