4 things to avoid after drinking coffee

Although coffee is good for health, improper consumption can be harmful to the body. In fact, many people unknowingly drink coffee incorrectly.

To reap the health benefits of coffee, people should avoid the following:

Drink coffee instead of meals.

Many people, due to busy schedules and a desire to lose weight, choose to drink a cup of coffee instead of breakfast. This is a harmful habit. Coffee can suppress hunger and make drinkers feel alert for a short time. However, coffee does not provide enough energy, protein, fat, or essential vitamins that the body needs to function, according to the health website Healthline (USA).

Besides helping you stay alert, coffee also supports metabolism and reduces the risk of certain chronic diseases.

Experts say that skipping breakfast and replacing it with coffee causes blood sugar to drop, increasing cravings for sweet and fatty foods in the evening. Additionally, drinking coffee on an empty stomach increases stomach acid, potentially leading to gastritis, ulcers, or chronic digestive disorders.

Drink coffee after taking medicine.

Coffee can affect how the body absorbs and metabolizes certain medications, from antibiotics to thyroid and antidepressants. A study published in the journal Clinical Pharmacokinetics showed that the caffeine in coffee may reduce the effectiveness of levothyroxine, a medication used to treat hypothyroidism. Therefore, patients should avoid drinking coffee at the same time or immediately after taking their medication.

In addition, coffee increases the excretion of calcium, iron, and magnesium. These are essential minerals for the body, often added to some medications or dietary supplements. Therefore, you should wait at least an hour after taking medication before drinking coffee.

Smoking while drinking coffee

The combination of caffeine and nicotine in cigarettes can create a temporary feeling of well-being, leading many people to develop the habit of drinking coffee and smoking at the same time. However, research shows that this habit doubles cortisol and adrenaline levels, two stress hormones, causing the heart to beat faster and blood pressure to rise.

Furthermore, coffee stimulates bowel movements, while nicotine constricts blood vessels. This results in strong contractions in the digestive system, easily leading to stomach ulcers or irritable bowel syndrome.

High-intensity exercise immediately after drinking coffee.

Although coffee is often used as a stimulant to increase athletic performance, drinking coffee and then immediately engaging in high-intensity exercise can be dangerous, especially for those with cardiovascular problems.

According to the Journal of Strength and Conditioning Research , caffeine increases heart rate and blood pressure. When combined with heavy weightlifting or high-intensity cardio, the heart is pushed to work overtime, easily causing dizziness, irregular heartbeat, or even fainting. For safety, it's recommended to wait about 30-60 minutes after drinking coffee before engaging in strenuous exercise, according to Healthline .
