What causes headaches when taking a nap in summer

1. Irregular naps. Some people have no habit of taking naps at all. Suddenly one day they start taking naps. At this time, their own biological clock is destroyed, and the biological clock disorder occurs, leading to dizziness and headaches after the nap.

2. Sleeping too long If you sleep too long, especially for more than two hours, your brain will be overly relaxed. If you wake up suddenly, it will stimulate your brain. Headache is a normal stress response. Therefore, the right nap time is also very important.

3. The head gets cold during a nap. Especially in the hot summer, people are very greedy for coolness. When taking a nap, many people like to use fans or air conditioners, or even directly face the air vents. This will cause a lot of cold air to the head and cause headaches. Therefore, it is recommended that you turn off the air conditioner during a nap, do not use fans, and do not sleep outdoors.

4. Covering your head during a nap If you cover your head for a long time while sleeping, the oxygen will be reduced; and your whole body will easily become hot, and the excess heat cannot be dissipated, which will affect your head and cause a headache after waking up.

Can't eat anything when having a headache

People with headaches should not eat foods containing nitrites, such as ham and sausage. People with headaches should not eat chocolate, which contains more phenylethylamine, a substance that activates blood vessels. Exogenous phenylethylamine passes through the blood-brain barrier and affects changes in blood flow in the brain. People with headaches should not eat foods that contain a lot of serotonin, such as seafood, eggs, milk, beer, coffee, oranges, tea, etc. After entering the human body, serotonin will be produced, leading to cerebral vasomotor dysfunction and aggravating headaches. Spicy and stimulating foods will stimulate the body to produce heat, speed up blood flow and aggravate headaches. People with high tyramine content should not eat foods, because after eating, amino acids are not easily decomposed, but instead promote the synthesis of prostaglandins, which causes strong dilation of extracranial blood vessels and inflammatory reactions, leading to headaches.

What fruits can I eat when I have a headache?

Headache patients can eat fruits with high vitamin C content. Vitamin C has antioxidant and anti-atherosclerotic effects, and can also enhance the body's resistance. Patients can eat mangoes, strawberries, apples, and oranges. These fruits are rich in vitamin C.
