Drinking coffee in the morning right after waking up is not good for your health.

Many studies have shown that coffee can have health benefits, but there are coffee drinking habits that can affect your energy, sleep, and overall health.

The following habits can affect your health:

Drinking coffee late in the day

Drinking coffee late in the day can affect sleep, as it can disrupt the body's ability to fall asleep or stay asleep.

This is due to the side effects of caffeine - a natural stimulant found in coffee that affects the central nervous system and its sleep-disrupting effects can last for several hours after drinking.

Research has shown that drinking coffee within 6 hours of bedtime can affect sleep quality. Sleep is important for disease prevention, mood, concentration and immune function. Therefore, it is recommended to limit coffee consumption within 6 hours of bedtime to ensure optimal sleep quality.

"It's okay to switch to decaf coffee after 2 p.m. or whenever you typically feel sluggish in the afternoon," Melissa Prest, a registered dietitian, told Health magazine.

Drink unfiltered coffee

Regular consumption of unfiltered coffees like French press, Turkish coffee, espresso can increase LDL cholesterol levels - also known as bad cholesterol.

Compared to filtered coffee, unfiltered coffee contains higher levels of diterpene compounds, especially kahweol and cafestol, which have been linked to increased levels of LDL cholesterol in the blood. High levels of LDL cholesterol have been shown to increase the risk of stroke and heart attack.

"If possible, opt for machine-brewed coffee with a paper filter. Save unfiltered coffee for weekends or special occasions if you're watching your cholesterol," says nutritionist Prest.

Adding too much sugar to coffee

Adding too much sugar and sweeteners to your coffee can spike your sugar intake, which can increase your risk of high blood pressure and chronic diseases like heart disease, cancer, and diabetes.

High sugar consumption also disrupts the balance of gut bacteria and may worsen symptoms of mental health disorders. Additionally, studies show that consuming too much added sugar contributes to weight gain and an increased risk of obesity.

Instead, enjoy your coffee black or lightly sweetened with a small amount of natural sweeteners like raw honey, date syrup, or pure maple syrup.

Drink coffee as soon as you wake up

To optimize your energy during the day, limit your coffee intake immediately after waking up. Drinking coffee immediately after waking up can interfere with the activity of adenosine - a neurotransmitter that affects your circadian rhythm (24-hour biological clock) and sleep-wake cycle.

To minimize this effect, Debbie Petitpain, a spokesperson for the Academy of Nutrition and Dietetics, suggests drinking your first cup of coffee about 60 to 90 minutes after waking up.

“During that time, stay hydrated, get some natural light, and do some light exercise to naturally wake you up. You may find that your coffee is more effective, and you may even need less of it—just by adjusting the timing of your coffee,” says Petitpain.

Use coffee as a meal replacement

Some people have a habit of drinking coffee instead of meals, whether with the goal of losing weight or out of personal preference. Coffee can help with weight loss and overall fat loss, but it is not nutritionally sufficient to replace a meal.

To ensure the benefits of coffee, it is recommended to use it after meals, such as breakfast to improve metabolism and control blood sugar levels better. A maximum of 400mg of caffeine should be consumed in 1 day to ensure health safety.
