Coffee is also sleepy, revealing the 6 major signs of body alarm

When the body is overloaded, even if there is no obvious physical exhaustion and psychological collapse, our bodies and brains will send a variety of signals to indicate, "really enough!" Recently, the Oprah Life Network in the United States has summed up "six codes for the body to exceed its limits."

Why do you feel sleepy when you drink coffee? reveal the six signals of the body calling the police.

1. I have a dream after taking a nap. Taking a nap can recharge your body. However, Dr. Christopher Winter, director of the Sleep Medicine Research Center at Massa Jefferson Hospital in Virginia, said the longest nap is about 30 minutes, usually in a light sleep. However, if you close your eyes during a nap and start having all kinds of strange dreams, it shows that the brain is seriously lack of sleep and can't wait to enter the deep sleep stage.

two。 My memory is getting worse. Dr. Annemarie Albano, director of the anxiety and related Diseases Clinic at Columbia University, said some healthy people have a poor memory. In fact, these people are "brain overload". Hormonal changes disrupt memory function, making it impossible for people to remember more and tend to forget recent events.

3. It's even worse after exercise. Dr. Sarah Berga, a professor of obstetrics and gynecology at Wake Forest University School of Medicine, said that in general, jogging for 45 minutes makes people feel relaxed, but if you feel tired as soon as you start exercising, your body is overloaded. Dr Boga's study found that stressed women who exercise at moderate intensity will lack energy and feel tired and tired.

4. I feel sleepy even when I drink coffee. Dr. Michael Bliss, an American clinical psychologist, said that brain activity changes after drinking coffee. If caffeine doesn't work, it means that the body and mind are extremely tired, counteracting the exciting effects of caffeine.

5. Eating mild foods can also aggravate pantothenic acid. A study published in the American Journal of Psychosomatic Medical Research confirms that stress does not cause pantothenic acid, but it can aggravate pantothenic acid. Even if you don't eat spicy and stimulating food, pantothenic acid symptoms still exist or are more severe, indicating excessive stress.

6. The scalp becomes sensitive. Dr. Richard Fred, an expert in clinical psychology in Pennsylvania, said that stress usually leads to an increase in neuropeptides and other natural chemicals in the skin, causing inflammation. This inflammation can break out in the form of acne or rosacea, and some can cause vasoconstriction, making the skin of the face and head too tight, tingling or sensitive.
