Light exercises in the evening like chair squats and calf raises can lead to a better night’s sleep and potentially mitigate the risk of diabetes and heart disease in older adults, a new study says. Previous studies have found that sitting for long periods and insufficient sleep are both linked to an increased risk of heart disease, diabetes and death. However, rigorous exercise before bed has long been discouraged as it can increase body temperature and heart rate, leading to poor sleep quality.
A new study, published in the journal BMJ Open Sport & Exercise Medicine, found that short bursts of light activity in the evening can extend sleep by as much as 30 minutes. In the first-of-its-kind research, about 30 participants completed two four-hour evening intervention sessions of prolonged sitting, and sitting interrupted with three-minute activity breaks every half hour. The intervention involved three exercises: chair squats, calf raises, and standing knee raises with straight leg hip extensions.
“These simple, bodyweight exercises were chosen because they don’t require equipment or a lot of space and you can do them without interrupting the TV show you are watching,” study co-author Meredith Peddie said. After the participants completed the exercise intervention, researchers found that they slept for 30 minutes longer. “We know that for many of us, our longest uninterrupted sitting happens at home in the evening.
In our previous studies we have found that getting .
