How does the time change affect our sleep and health?
Quick Answer: The time change caused by Daylight Saving can disrupt your sleep cycle, leading to tiredness and mood changes. It may briefly affect your heart health and concentration. Most people adjust within a few days, but the initial shift can be rough.
When clocks move forward or backward, your body’s internal clock, called the circadian rhythm, gets thrown off. This can reduce your total sleep time and lower sleep quality. That groggy feeling after the change comes from your brain trying to reset.
The sudden shift also stresses the heart slightly, increasing risks of heart attacks and strokes for a short time. Concentration and reaction times may dip, raising the chance of accidents. Luckily, most people bounce back quickly once their bodies adapt.
