NASA Warns of 'Social Jet Lag' Health Risks
Imagine your body has a built-in clock that wants you to sleep and wake at the same times every day.
Social jet lag happens when you don't follow your body's clock.
It's like having jet lag without traveling!
When you sleep at different times, especially on weekends, your body gets confused.
This can make you feel tired, unfocused, and even affect your health.
NASA scientists say it's important to go to bed and wake up around the same time every day to feel your best.
To fix social jet lag, try getting sunlight in the morning and making sure your bedroom is dark and quiet.
Social jet lag occurs when sleep schedules are inconsistent, misaligning with the body's natural clock.
NASA scientists warn that social jet lag can lead to fatigue, poor focus, and negative health impacts.
Sleeping in on weekends can worsen social jet lag, intensifying morning grogginess and sleep inertia.
Health risks associated with social jet lag include cardiovascular issues, metabolic disorders, and mental health problems.
Experts recommend consistent sleep schedules, morning light exposure, and environment optimization to combat social jet lag.
- Who
