1. People Who Are Sensitive to Caffeine
Some people can drink coffee in the evening and fall asleep without a problem. Others can have one cup in the afternoon and find themselves awake hours later.
Caffeine can cause or worsen symptoms such as:
- Restlessness
- Nervousness
- Shakiness
- Rapid heartbeat or palpitations
- Difficulty falling asleep
- Headaches
People who notice these effects may benefit from reducing their intake or switching to lower-caffeine
