Un­in­ter­rupted sleep the best

right). IF YOU want to be alert and ready to face the day, it’s bet­ter to have an un­in­ter­rupted night’s sleep, even if it’s not for the stan­dard eight hours.

A new US study shows that in­ter­rupted sleep is less restora­tive, and leads to a worse mood than a lack of sleep caused by go­ing to bed late.

Young par­ents and night work­ers are well aware that broken sleep makes you tired, but can also af­fect your mood.

Re­searchers at the Johns Hop­kins Univer­sity in Bal­ti­more in the US demon­strated that in­ter­rupted sleep and forced awak­en­ings had a nega­tive im­pact on mood.

These re­duced en­ergy lev­els and feel­ings of sym­pa­thy and friend­li­ness on a big­ger scale than a lack of sleep, or sim­ply go­ing to bed late.

The find­ings of this study sug­gest that nega­tive mood lev­els such as sad­ness and anger emerged on suc­ces­sive nights.

The re­searchers also noted dif­fer­ences in sleep struc­ture.

The group which had in­ter­rupted sleep had very short pe­ri­ods of deep, slowwave sleep, com­pared to the group of sleep­ers who went to bed late.

Deep sleep is the key to the feel­ing of restora­tion, the re­searchers say.

In­suf­fi­cient deep sleep could, there­fore, have a greater ef­fect on re­duced pos­i­tive mood, tired­ness, and en­ergy lev­els.

This ex­per­i­men­tal study on hu­mans also high­lighted for the first time that the par­tial loss of sleep caused by suc­ces­sive awak­en­ings is more dam­ag­ing to mood than a lack of sleep, or a shorter night’s sleep.

The re­searchers also be­lieve that these re­sults sug­gest that there could be a con­nec­tion be­tween de­pressed moods and in­som­nia. – AFP
