What is adrenaline
Adrenaline is a hormone that is produced in a situation when a person is under stress, danger, scared or excited.
The adrenaline rush starts in the brain. When you are in a stressful environment or a dangerous situation, this information is sent to the amygdala. The amygdala receives the signal, perceives the threat and sends the information to the hypothalamus. It is with the help of the hypothalamus that the signal is transmitted to the adrenal gland - in the end, adrenaline is already in the blood circulation system and you are ready to adequately respond to the threat.
The reason for the adrenaline rush may be:
- Horror movie;
- Parachute jump;
- Climbing;
- Zipline;
- Rafting
- Cage swimming with sharks and other activities.
The following symptoms appear during an adrenaline rush:
- Sweating
- Rapid heartbeat;
- Increased sensitivity;
- Rapid breathing;
- A person cannot feel pain;
- Dilated pupils;
- Excitement.
A heightened reaction is required in an adequate situation, but an adrenaline rush at a completely inappropriate moment causes discomfort. For example, an overdose of adrenaline generated at night will not really allow you to sleep.
A person may be comfortably snuggled up in a bed, in a cozy bedroom, but if he does not stop thinking about the unpleasant news during the day or tomorrow, it is impossible to sleep in so.
The reason for the production of adrenaline may be:
- Strong noise;
- Bright light;
- High temperature;
- Watching TV, scrolling on mobile or listening to loud music before going to bed.
