4. It may lead to weight gain.

Although black coffee may help you burn fat, it can also upset your healthy sleep patterns. When you don’t get enough sleep, you tend to feel hungrier and have more cravings for sweet snacks. Many coffee beverages, like popular sweetened blends, are packed with sugar and calories and might cause you to gain extra pounds.
5. It can worsen anxiety.
When you wake up in the morning, your stress hormones levels are usually at their highest. Because caffeine is a stimulant, it gives your body a jittery effect and can even trigger anxiety attacks for some people.
6. It can dry out your skin.

Because coffee makes you use the restroom more often, it dehydrates your body. When you become dehydrated, it’s harder for toxins to exit the body through your skin. This, in turn, dries the skin out and makes it more vulnerable to various problems, like premature wrinkles.
7. It may raise your blood sugar level.

Your morning cup of coffee makes it harder for your cells to regulate blood sugar, which can lead to various diseases. High blood sugar, in turn, can lead to weight gain and even raise your risk of skin infections.
When do you usually drink your first cup of coffee? Have you noticed any of these side effects?
