If you find yourself feeling tired after some sleep, you might have sleep inertia. Sleep inertia means that upon waking up, you feel very tired. You’ll suffer from similar symptoms of sleep-deprivation, such as having a bad mood. Luckily, this feeling usually lasts 30 minutes. So, next time you wake up sleepy, try some of these tricks. 1
As soon as you wake up, you can start exercising. Since you just woke up, you shouldn’t do any intense or long exercises first thing in the morning. Try walking, climbing stairs, or squats.
Good old caffeine. This drug works it’s magic by blocking adenosine receptors. Adenosine is a chemical made by your body to help you sleep. As a result, you’ll be more alert and awake. Caffeine is found in coffee, tea, and chocolate. 2
Assuming it’s daylight when you woke up, go outside. The circadian rhythm in your brain determines whether it’s nighttime or daytime. If your circadian rhythm detects blue light (daytime), you’ll feel more energized.
Take a shower
The trick is to alternate between cold and warm water. Make the water as cold as possible and stand under the water for 30 seconds. Now make the water as hot as you can and stand under the water for 30 seconds. By doing this, you’ll have more blood flow, waking you up. 3
