2. You have a different bedtime schedule on the weekends
Your body runs on consistency. In fact, it needs this consistency to be able to operate smoothly. So when you go against your usual bedtime to go out for drinks with your friends on the weekend, it could cause dysfunction and ultimately — health problems.
It’s the same with sleeping in and waking up late. Most people try to compensate for their lost sleep on weekdays over the weekend. If you do, don’t expect any sleep on Sunday on your weekday bedtime schedule. These irregularities can actually disturb your sleep cycle and cause long term damage.
Sleep doctors call this phenomenon “social jet lag,” as you are forcing your body to go back and forth between two different timezones per week. This can disturb your biological cycle and cause potential health risks. This can cause anxiety, stress, headaches, grogginess, crankiness, and even depression. Not only that, it makes you incredibly lazy.
