As we all know, caffeine can promote the brain. It can prevent a neurotransmitter called adenosine from being transmitted to brain receptors, which is used to regulate our sleep cycle. This prevents adenosine from telling the brain that you are tired, which is why we feel more energetic and awake after drinking coffee.

2. Exercise

Although you may feel tired when you are sleepy, doing exercise can relieve stress and benefit your brain health. Maybe run a few laps or do a set of yoga. After sweating, you are not as sleepy as before.

3. Smelling oranges

The smell of oranges can stimulate human senses and make people feel refreshed.
