Why do I get a headache after working out?

Nowadays, more and more people like to go to the gym or other places to exercise, because fitness can not only strengthen the body, but also alleviate the occurrence of sub-health conditions. However, many people overdo it in order to achieve the desired fitness results. After doing so, they develop headaches. So, what exactly is going on when a person develops a headache after doing so?

Failure to fully recover after training indicates overtraining. Typical symptoms are: frequent fatigue, irritability, poor sleep, poor appetite, joint pain, headache, nausea, and lack of energy. Any of these symptoms can dampen your enthusiasm for training and prevent you from giving your all. Gym addiction is a precursor to this symptom, and if you've hit a wall in recovery, the only cure is to leave the gym completely until your passion for training is rekindled. Of course, it is better not to touch this wall at all, but if you do touch it, you should pay attention to recovery.

In addition, another reason for headache is related to the environment. Generally, we should pay attention to the following points:

One is the construction pollution of the new gym. Pollution from formaldehyde and benzene caused by interior decoration and indoor carpets. Radon exists in construction cement, slag bricks, decorative stones and soil. Its main harm to the human body is causing lung cancer. Ammonia in concrete antifreeze, formaldehyde in various boards and benzene in paints, glues and various interior wall coatings are also harmful to the human body.

Second, the density of people in the gym is inappropriate, causing human pollution. Especially in some aerobics rooms, the density of people is too high, and the breathing volume of the participants is relatively large. The production of carbon dioxide from breathing is more than twice that when they are still. Not only will there be a lack of fresh air in the room, but the participants will also inhale more harmful substances. According to research, a normal person breathes 30 cubic meters per hour, and during strenuous activities, the volume is more than 50 cubic meters per hour. If 20-30 cubic meters of fresh air are supplied per person per hour, the carbon dioxide content in the indoor air can be below 0.1%, and the air is relatively clean. However, gyms generally use underground buildings, are relatively closed, and lack independent ventilation systems, which can easily lead to a serious lack of fresh air volume, causing people to feel nausea, headaches and other discomforts. On the other hand, when there are many people in the gym, the odor discharged from the human body and microorganisms such as bacteria and viruses coexist with air particles, causing pollution.

The third is noise pollution. National regulations stipulate that dynamic noise in entertainment venues must not exceed 85 decibels, but gyms generally far exceed the standard. Long-term exposure to noise can increase adrenal secretion, leading to a series of uncomfortable symptoms such as cerebral vasoconstriction, increased heart rate, headache, decreased memory and concentration, weakened digestion, and physical and mental decline.
