For those who are in the habit of poking the leg out of the bed sheet when sleeping

Limit daytime naps. Long naps during the day can interfere with nighttime sleep. If you have one, don’t let it last more than an hour and don’t let it be too late.

Get physical activity. Regular exercise can promote better sleep. However, as with meals, avoid activity too close to bedtime.

Manage worries. It may be very difficult, but you should try to resolve worries or concerns before bed. Or at least try to leave them outside the bedroom.
