1. Lingering in Bed After Waking Up

Many office workers struggle to get up early due to heavy workloads and tend to stay in bed. While adequate sleep relieves fatigue and restores energy, some mistakenly believe oversleeping boosts health, especially for teenagers’ growth, and thus stay in bed far longer than necessary. This bad habit harms physical health over time.

After an overnight fast, the stomach is empty and hunger sets in. Lying in bed disrupts the regular rhythm of gastrointestinal activity, damaging gastric mucosa and triggering gastritis, gastric ulcers and indigestion in the long run.

It is vital to maintain a reasonable sleep schedule and healthy daily routines.

2. Rushing to Urinate Right After Waking Up

The bladder fills with urine overnight, creating an urgent urge to urinate. However, one should not jump out of bed to empty the bladder immediately no matter how strong the urge is.

Emptying the bladder abruptly upon waking may lead to dizziness and even micturition syncope.

3. Doing Strenuous Exercise Immediately After Getting Up

Moderate morning exercise brings benefits, yet improper timing negates these advantages.

If you wish to work out in the morning, rest for a while after waking up and wait until qi, blood, yin and yang regain balance. Otherwise, strenuous activity may trigger cardiovascular and cerebrovascular emergencies.

4. Skipping Breakfast

Nutrition experts confirm that breakfast is the most important meal of the day. After sleep, the body is ready for work and study, requiring abundant nutrients to sustain daily energy expenditure.

Harms to the Brain

Brain tissue accounts for only 2%–3% of body weight, yet it receives about 800 ml blood flow per minute, consumes 45 ml oxygen per minute and uses roughly 5 grams of glucose hourly.

Teenagers’ developing brains demand even more blood, oxygen and glucose than adults. Persistently low blood sugar impairs mental activity and permanently hinders brain growth and development.

Harms to the Digestive System

Food from the previous night empties out of the stomach into intestines in about six hours without breakfast the next morning. Gastric acid and digestive enzymes will erode the stomach’s mucosal lining instead of digesting food.

Over time, the stomach cells’ mucus-secreting function deteriorates, greatly increasing risks of gastric and duodenal ulcers.
